AI in Real Estate Appraisal:Does AI Change the Rule?

Artificial intelligence is moving into the real estate appraisal profession fast. At seminars, conferences, and professional discussions, appraisers are increasingly being encouraged to bring ChatGPT and other AI tools into their work.

There’s nothing wrong with that on its own. Used well, AI can be a genuinely useful tool for appraisers.

The trouble starts when AI is pitched as something you can simply ask to determine a property’s value — sometimes without even inspecting the property. That proposition deserves closer scrutiny.

AI Does Not “Know” Property Value

Ask an AI system for a property’s value and it will often produce an estimate readily — one that can look remarkably precise.

But where did that number come from?

Market value isn’t information AI inherently possesses. A credible opinion of value has to be supported by relevant market evidence, and AI is only as useful as the information it has to draw on.

This matters most in markets where reliable transaction data is thin. Where actual selling prices, property characteristics, transaction dates, and similar information are publicly available and systematically recorded, automated valuation systems have a lot to work with. Where that information is fragmented, privately held, hard to verify, or simply unavailable, the picture changes completely.

Online listings may be abundant, but an asking price is not a transaction price. A property listed at ₱20 million may eventually sell for ₱16 million. Another may never sell at all. A transaction may involve unusual financing, related parties, package deals, distress, or other conditions that never make it into the listing.

An AI system that doesn’t know any of this can still produce a confident-sounding estimate. That’s exactly where the danger lies.

Precision Is Not the Same as Reliability

Suppose an AI system concludes that a parcel of land is worth ₱18,437 per square meter. The figure looks scientific because it’s precise.

But suppose the data behind it consists mostly of asking prices, duplicated listings, outdated postings, mislocated properties, and transactions whose actual consideration was never verified.

No amount of sophistication in the calculation can make up for weak evidence underneath it. Worth remembering:

Precision of output is not reliability of value.

A sophisticated algorithm run on unreliable information just produces a sophisticated-looking but unreliable conclusion. Garbage in, garbage out didn’t go away because AI showed up.

ChatGPT Is Not an Automated Valuation Model

This distinction gets missed constantly.

ChatGPT and similar generative AI tools are general-purpose systems, built to understand, organize, analyze, and generate information. An Automated Valuation Model (AVM), by contrast, is purpose-built to estimate property values using defined property databases, transaction data, statistical techniques, and valuation models.

They are not the same thing.

Even a well-designed AVM has limits — its reliability depends heavily on the quantity, quality, recency, and representativeness of its underlying data. If a specialized valuation model struggles when market information is inadequate, there’s even more reason for caution when a general-purpose AI system is asked to value a specific property without being handed sufficient, reliable evidence to work from.

AI can process information. It cannot manufacture reliable market evidence where none exists.

Can AI Replace Property Inspection?

An equally concerning idea is that AI has made physical inspection unnecessary.

There may be legitimate cases for desktop or limited-scope valuation, depending on the applicable standards, the purpose of the assignment, the evidence available, and the agreed scope of work. But that’s a very different claim from saying AI removes the need for inspection altogether.

Consider what an appraiser actually finds on-site that no database captures reliably:

  • actual road access and road width
  • topography and elevation
  • physical condition of improvements
  • neighborhood influences
  • encroachments, easements, and rights-of-way
  • flooding or drainage conditions
  • transmission lines and other infrastructure
  • actual frontage
  • surrounding land uses
  • quality of views
  • occupancy
  • inconsistencies between documents and actual conditions
  • other physical characteristics affecting utility and marketability

A database may show a property fronting a road. Inspection may reveal the “access” is a narrow passage shared with several other lots. A map may show a regular, developable parcel. Inspection may reveal severe topographical limitations. Records may describe a residential improvement in good condition. Inspection may reveal serious deterioration.

AI cannot analyze a property characteristic it was never given. Technology doesn’t eliminate the need to actually understand the property being valued.

AI Cannot Cure Inadequate Appraisal Evidence

This may be the single most important idea in the whole discussion: AI cannot cure inadequate appraisal evidence.

Technology can process evidence faster. It can surface relationships within that evidence. It can organize thousands of data points at once. What it cannot do is turn unreliable information into reliable market evidence just by running it through a model.

The difference plays out like this:

  • AI + poor data + no verification + no appropriate inspection → a potentially misleading estimate
  • AI + reliable data + professional verification → genuinely useful analytical assistance
  • AI + reliable data + appropriate inspection + sound methodology + professional judgment → powerful appraisal support

The difference isn’t the sophistication of the AI. It’s the quality of the appraisal process around it.

Can AI Apply the Correct Valuation Method?

Even with sufficient data, another question remains: can AI determine the appropriate method for valuing a given property?

AI can certainly run the calculations. Given verified comparable sales, transaction dates, property characteristics, and defensible adjustments, it can assist with the Sales Comparison Approach — computing unit values, applying adjustments, analyzing ranges, testing alternative assumptions. Given reliable rents, vacancy rates, operating expenses, capitalization rates, and growth assumptions, it can run the Income Approach, including capitalization and discounted cash-flow analysis. Given reliable land values, construction costs, depreciation, and obsolescence data, it can assist with the Cost Approach.

But performing a method correctly is not the same as selecting the right method. That distinction is fundamental.

A Correct Calculation Can Still Produce the Wrong Appraisal

Take a beachfront resort property. An AI system might pull nearby land listings, calculate price per square meter, apply mathematical adjustments, and produce an indicated value — flawlessly.

But what if buyers of comparable resort properties actually base their decisions on income-generating capacity, development potential, tourism demand, or redevelopment opportunity, not raw land comparables? The math can be correct while the underlying methodology is entirely wrong for the asset.

The same trap applies to hotels, industrial properties, special-purpose properties, leasehold interests, partial takings, landlocked parcels, properties burdened by transmission-line easements, environmentally constrained sites, and properties with significant redevelopment potential.

AI can calculate almost anything. The professional question is whether that’s what should have been calculated in the first place. A correct calculation using the wrong valuation method is still a wrong appraisal.

Highest and Best Use Comes Before the Method

There’s a deeper layer still. Before an appraiser even selects a valuation approach, they must determine the property’s highest and best use.

A vacant parcel might physically resemble the residential lots around it. But its zoning, accessibility, location, development trends, physical characteristics, and market demand may point to an entirely different use. Get the highest and best use wrong, and everything downstream can be technically sophisticated and still conceptually wrong.

The proper sequence looks like this:

  1. Identify the property and property rights
  2. Define the appraisal assignment and valuation date
  3. Inspect and investigate as appropriate
  4. Analyze physical, legal, economic, and market characteristics
  5. Determine highest and best use
  6. Select the appropriate valuation approach and method
  7. Apply relevant, verified market evidence
  8. Reconcile the value indications
  9. Form the opinion of value

AI can assist at nearly every one of these stages. But if the whole process starts and ends with a single prompt — “What is the value of this property?” — most of the essential valuation questions never actually get answered.

AI May Spot Similarity — The Appraiser Determines Comparability

Comparable-property analysis is a good illustration of where AI genuinely helps and where it can’t take over.

Given enough reliable data, AI can screen hundreds or thousands of properties and flag those that look statistically similar to the subject. That’s valuable. But statistical similarity is not the same as appraisal comparability.

Two properties can have nearly identical lot areas and sit a short distance apart, yet differ substantially because one has better road access, wider frontage, superior topography, a better view, flood exposure, a transmission-line easement, development restrictions, stronger commercial exposure, or a different highest and best use altogether.

AI may identify statistical similarity; the appraiser determines comparability. Selecting comparables isn’t a search for similar numbers — it requires understanding which characteristics actually drive buyer and seller behavior in that specific market.

Where AI Can Truly Help

None of this means appraisers should reject AI. Quite the opposite — they should learn to use it well.

AI can help organize large datasets, screen potential comparables, analyze market trends, review documents, summarize regulations, flag inconsistencies, run statistical analyses, prepare sensitivity tests, work through income and expense figures, check calculations, and sharpen the clarity and consistency of appraisal reports. It can cut the time spent on repetitive work dramatically.

It’s also an effective quality-control tool — spotting inconsistencies between sections of a report, stress-testing assumptions, checking math, comparing scenarios, and flagging items that need further investigation.

Used well, AI frees the appraiser to spend more time where professional expertise actually matters most: verification, interpretation, highest and best use, methodology, comparability, reconciliation, and judgment. The right relationship looks like this:

AI assists → the appraiser verifies → the appraiser analyzes → the appraiser judges → the appraiser takes responsibility.

The Appraiser Still Signs the Report

This point shouldn’t get lost in the enthusiasm.

If an appraisal contains an unsupported adjustment, an inappropriate comparable, a wrong assumption, the wrong valuation method, or a flawed conclusion, the appraiser cannot fall back on “the AI generated it.” The professional who adopts the analysis and signs the report remains accountable for the opinion of value.

Artificial intelligence does not assume professional accountability. The appraiser does.

The Wrong Question About AI and Appraisal

The debate shouldn’t really be whether AI can produce a property value. Of course it can — a calculator can produce a number, a spreadsheet can produce a number, a regression model can produce a number, an AVM can produce a number, and so can ChatGPT.

The question that actually matters is: can the appraiser demonstrate that the resulting opinion of value is supported by sufficient, relevant, verified market evidence, appropriate methodology, and sound professional judgment?

That’s what separates a numerical estimate from a defensible professional appraisal.

AI Will Change Appraisal — Not Its Foundations

AI is going to reshape this profession. Data gathering will get faster. Market databases will get more sophisticated. Comparable searches will become increasingly automated. Statistical analysis will become accessible to far more practitioners. Report preparation and quality control will get dramatically more efficient. All of that is worth welcoming.

But the fundamentals of valuation don’t move. The appraiser still has to understand the property. Still has to understand the market. The evidence still has to be relevant, and the data still has to be verified. Highest and best use still has to be analyzed. The methodology still has to be appropriate. The conclusion still has to make economic sense. And someone still has to exercise professional judgment and take responsibility for the resulting opinion.

So the better message to appraisers isn’t “use AI to determine property value.” It’s this: use AI to strengthen the appraisal process, but never let it substitute for the evidence, verification, appropriate inspection, methodology, market analysis, and professional judgment an opinion of value actually depends on.

The future of appraisal isn’t AI versus the appraiser. It belongs to the appraiser who knows how to use AI effectively — and just as importantly, knows its limits and when its output shouldn’t be trusted.

Because the challenge in appraisal has never really been producing a number. It’s being able to explain and defend why that number represents value.

Article 4 and the Fight Over Wage Order NCR-27

The controversy surrounding NCR Wage Order No. 27 is not simply a dispute over an ₱85 minimum-wage increase. At its core is a more fundamental question about the allocation of governmental authority: when Congress creates a specialized mechanism for fixing and reviewing minimum wages, may an employer sidestep that mechanism, seek declaratory relief from a Regional Trial Court, and obtain an injunction against a wage order’s implementation?

That question is now before the Supreme Court, on a Petition for Certiorari and Prohibition filed by labor organizations challenging RTC orders that restrained the implementation of Wage Order No. NCR-27. The petition asks, among other things, whether RTCs may issue TROs or injunctions against wage orders despite Article 126 of the Labor Code, whether declaratory relief is available despite the specific administrative remedy under Article 123, and whether the RTCs committed grave abuse of discretion in entertaining the cases at all.

The dispute sits at the intersection of labor law, administrative law, remedial law, and statutory construction. But one provision deserves more attention than it has so far received: Article 4 of the Labor Code. Interestingly, the pending petition does not expressly develop Article 4 as part of its statutory-construction argument — an omission that opens an important additional line of analysis.

Congress Built a Specialized Wage-Setting System

The starting point is Republic Act No. 6727, the Wage Rationalization Act of 1989. It created the Regional Tripartite Wages and Productivity Boards (RTWPBs) to determine and fix regional minimum wages, with the National Wages and Productivity Commission (NWPC) exercising supervisory and review functions over them.

This was a deliberate institutional choice. Minimum-wage determination requires weighing the cost of living, workers’ needs, prevailing wage levels, employers’ capacity to pay, employment generation, and reasonable returns on investment — not questions of law alone, but ones demanding economic data, policy judgment, consultation, and specialized expertise. The Supreme Court has accordingly characterized the issuance of a wage order as an exercise of quasi-legislative power delegated by Congress, and the pending petition itself invokes Metropolitan Bank and Trust Co. v. NWPC for that proposition.

The statutory division of labor can be summarized simply:

  • RTWPB — fixes regional minimum wages
  • NWPC — administratively reviews wage orders
  • Courts — exercise judicial review, when properly invoked

NCR-27 tests the boundaries between these three functions.

From the RTWPB to the RTC

According to the petition, RTWPB-NCR issued Wage Order No. NCR-27 on June 23, 2026, providing for a phased increase of ₱60 effective July 25, 2026 and a further ₱25 effective January 20, 2027 — a total adjustment of ₱85.

On July 23, Readycon Trading and Construction Corporation and R-II Builders, Inc. filed a Petition for Declaratory Relief with Prayer for Preliminary Injunction, TRO and/or Status Quo Ante Order before the Pasig RTC. The court subsequently issued orders restraining implementation of the wage increase. A separate Rule 63 petition involving NCR-27 was also filed before the Navotas RTC.

This raises an obvious procedural question: why resort to declaratory relief when the Labor Code already provides a remedy for a party aggrieved by a wage order?

Article 123 Already Tells an Aggrieved Employer What to Do

Article 123 supplies a specific administrative remedy. An aggrieved party may appeal a wage order to the NWPC within ten calendar days of publication, and the NWPC must decide that appeal within sixty calendar days.

Crucially, Congress also decided what happens to the wage order while the appeal is pending: filing an appeal does not stay the order, unless the appellant posts an undertaking, with satisfactory sureties, to pay the wage increase should the order be affirmed.

In other words, Congress didn’t just name an appellate body — it specified who may challenge a wage order, when, where, how quickly the challenge must be resolved, and whether the challenge suspends implementation in the meantime.

The statutory route looks like this:

RTWPB → Wage Order → NWPC Appeal (no automatic stay)

What happened in the challenged cases looks like this instead:

RTWPB → Wage Order → RTC Declaratory Relief → TRO/Injunction (wage increase stopped)

That distinction is precisely why the pending petition argues that Rule 63 is being used as a substitute for a lost Article 123 appeal — one of the central questions petitioners want the Supreme Court to resolve.

But What Exactly Is There to “Declare”?

There’s a more basic question underneath the procedural one. Declaratory relief exists to resolve genuine uncertainty about legal rights and obligations before any breach occurs — it is preventive, not corrective. But disagreement with a governmental decision is not the same thing as ambiguity in the governing law.

Article 123 already tells an aggrieved employer exactly what remedy to pursue. Article 126 separately restricts judicial injunctions against proceedings before the NWPC and the Regional Boards. The statutory wage-setting mechanism has existed since 1989 — yet the pending petition itself describes the use of declaratory relief against wage orders as a novel maneuver deserving definitive Supreme Court guidance.

That produces a logically prior question: if the Labor Code already tells an aggrieved employer where to go, when to appeal, what happens during the appeal, and what courts may not enjoin, what exactly is left for an RTC to “declare”?

A party’s dissatisfaction with the legal consequences of a statute does not, by itself, create the kind of uncertainty Rule 63 contemplates. None of this means wage orders are immune from judicial review — they plainly are not. The real issue is whether declaratory relief is the proper vehicle, especially where Congress has already supplied a special statutory remedy.

A Lost Appeal Cannot Simply Become Declaratory Relief

The petition makes this argument directly: the employers failed to exhaust the administrative remedy under Article 123, and declaratory relief cannot serve as a substitute for a lost appeal.

Consider the alternative. Congress gives an aggrieved employer ten days to appeal a wage order. The employer lets that period lapse. It then files a declaratory-relief petition challenging the same wage order and obtains an injunction anyway. If that route is freely available, what remains of the ten-day statutory appeal period? The issue, then, is not merely procedural preference — it’s whether a general remedy under Rule 63 may be used to circumvent a special remedy that the Labor Code specifically created.

Primary Jurisdiction: Courts Are Not Wage Boards

The controversy also implicates the doctrine of primary jurisdiction — the principle that courts ordinarily defer, in the first instance, to questions Congress has placed within an administrative agency’s special competence, particularly where specialized expertise is required.

This matters most where an employer’s objections concern:

  • capacity to pay
  • reasonable returns on investment
  • economic impact
  • employment consequences
  • the proper amount of the wage adjustment

These are exactly the kinds of economic questions the RTWPBs were created to evaluate. The distinction that matters is between judicial review — asking whether the RTWPB acted according to law — and judicial substitution — a court reweighing the economic considerations Congress entrusted to the RTWPB in the first place. Courts retain the power to determine legality and constitutionality, but that doesn’t make an RTC an alternative wage-setting or appellate body.

Article 126 and the Anti-Injunction Question

Article 126 provides that “no preliminary or permanent injunction or temporary restraining order may be issued by any court, tribunal or other entity against any proceedings before the Commission or the Regional Boards.”

Petitioners argue this prohibition bars courts from restraining NCR-27, and that a status quo ante order cannot accomplish indirectly what the law forbids directly. But the text raises an interesting wrinkle: Article 126 refers to “proceedings before the Commission or the Regional Boards” — it does not expressly say “implementation of an already-issued wage order.”

An employer could therefore advance a narrow textual reading: once the RTWPB completes its hearings and issues the wage order, the “proceedings before” the Board have ended, so an injunction against subsequent implementation is not literally an injunction against an ongoing proceeding. That is arguably the strongest textual counterargument available to the employers.

But Article 126 does not exist in isolation.

Articles 123 and 126 Must Be Read as One Statutory Scheme

Article 123 establishes the means for challenging a wage order and deliberately provides that an appeal does not automatically stay it. Article 126 restricts judicial injunctions against proceedings before the wage-setting authorities. Read together, they reveal a coherent design:

RTWPB → Wage Order → NWPC review → no automatic suspension of the wage order

Compare that to the RTC route actually taken:

RTWPB → Wage Order → Rule 63 declaratory relief → TRO/Injunction → wage order suspended

A general judicial remedy would then accomplish exactly what the special statutory remedy was designed not to automatically allow. The petition argues that Congress structured Article 123 to protect workers from losing a wage increase during the review process, and that a judicial stay obtained outside that mechanism defeats the design. This is where statutory construction — and Article 4 — becomes central.

The Missing Interpretive Rule: Article 4 of the Labor Code

The pending petition develops Articles 123 and 126 extensively, along with declaratory relief, exhaustion of administrative remedies, primary jurisdiction, and the constitutional mandate to protect labor. What it does not expressly develop is Article 4 as an independent rule of statutory construction.

Article 4 provides that all doubts in the implementation and interpretation of the Labor Code and its implementing rules shall be resolved in favor of labor. How much weight this provision deserves depends entirely on how the Court reads Article 126.

If Article 126 is clear, apply it as written. Petitioners’ primary position is that Article 126 is unambiguous. If that’s correct, Article 4 has no work to do — a clear statute is applied, not construed. But that conclusion cuts both ways: if Article 126 is already clear, where is the uncertainty that supposedly justified declaratory relief in the first place? Article 123 is equally clear about the administrative remedy available to an aggrieved employer. If both provisions are unambiguous, the threshold question isn’t how an RTC should interpret them — it’s why declaratory relief was necessary at all. Disagreement with a wage order is not the same as uncertainty about what the law means.

If Article 126 is ambiguous, Article 4 arguably enters the analysis. Suppose the Court were to accept that the phrase “proceedings before the Commission or the Regional Boards” creates genuine uncertainty as applied to an injunction against an already-issued wage order’s implementation. Under ordinary canons of statutory construction, the analysis would then typically proceed in stages: first, harmonizing Articles 123 and 126 as one statutory scheme rather than reading either in isolation; and only if genuine doubt survived that harmonization, turning to Article 4, which directs that residual doubt be resolved in favor of labor. On this view, Article 4 functions not as a rhetorical appeal to social justice but as a legislatively prescribed interpretive rule — part of the very statute whose meaning is in dispute.

The Declaratory-Relief Dilemma

This produces what may be the sharpest tension in the whole controversy:

  • If there is no ambiguity, why is declaratory relief necessary?
  • If there is genuine ambiguity, what role is left for Article 4 to play in resolving it?

Article 4 cannot manufacture ambiguity, cure jurisdictional defects, or eliminate an employer’s legal rights — it doesn’t decide the case by itself. But it creates a real interpretive bind: the harder a party argues that the law is uncertain to justify going to the RTC, the more relevant the Labor Code’s own rule for resolving that uncertainty becomes. And the harder a party insists the law is already clear, the harder it becomes to explain what declaratory relief was supposed to declare in the first place.

A Three-Level Framework, If One Were to Build It

One way petitioners could structure this argument, drawing on ordinary canons of construction, is in three levels, applied in sequence:

  1. Plain meaning. If Articles 123 and 126 are clear, apply them as written. Article 123 supplies the specific remedy; Article 126 supplies the restriction on injunctive intervention.
  2. Harmonization. If Article 126 requires interpretation, read it alongside Article 123 so that a general Rule 63 remedy doesn’t defeat the special review mechanism Congress deliberately built.
  3. Article 4. If genuine doubt survives even after harmonization, Article 4 directs that it be resolved in favor of labor.

That kind of sequence would be considerably stronger, as a matter of legal method, than simply invoking “labor should always be favored” — it starts from text, moves to the statutory scheme as a whole, and reaches Article 4 only as a last resort. Whether the Court adopts this or any other framework is, of course, for the Court to decide.

Rule 63 Has Another Problem: Necessary Parties

Even setting aside whether declaratory relief was theoretically available, the petition raises a separate procedural defect: Rule 63 requires that persons who have or claim an interest affected by the declaration be made parties to the case. According to the petition, the labor organizations that initiated the wage petitions leading to NCR-27 were never impleaded in the RTC proceedings.

Taken together, the Rule 63 controversy involves several distinct, connected questions:

  • Was there genuine uncertainty appropriate for declaratory relief?
  • Can Rule 63 bypass Article 123’s special remedy?
  • Can declaratory relief substitute for a lost appeal?
  • Does primary jurisdiction require resort to the specialized administrative mechanism first?
  • Were all interested parties joined?
  • Can the RTC issue injunctive relief at all, given Article 126?

Why Certiorari and Prohibition?

The labor organizations went to the Supreme Court through Rule 65, not to argue that ₱85 is the economically correct figure, but to challenge the RTCs’ authority to entertain the Rule 63 cases and issue restraining orders — alleging grave abuse of discretion amounting to lack or excess of jurisdiction. Certiorari seeks to annul judicial acts already performed with grave abuse of discretion; prohibition seeks to stop courts from continuing proceedings allegedly beyond their lawful authority. Because the petition was filed directly with the Supreme Court, petitioners also invoke recognized exceptions to the hierarchy of courts: transcendental importance, a case of first impression, pure questions of law, public welfare, patent nullity, and the absence of any other plain, speedy, and adequate remedy.

What If the Immediate Controversy Becomes Moot?

TROs expire. Injunctions may be lifted. Wage orders may eventually take effect. The petition anticipates this and argues that the Court has discretion to resolve the legal questions anyway, citing the public interest at stake, the need for guidance to the Bench and Bar, and the likelihood that this same pattern will recur:

RTWPB issues a wage order → employer files declaratory relief → RTC issues a TRO or injunction → implementation is delayed → the immediate controversy eventually disappears → another wage order produces another case

Without definitive guidance, this cycle could repeat indefinitely — which is why the eventual ruling may shape the procedure for challenging every future wage order, not just NCR-27.

Does Judicial Intervention Render the RTWPB Inutile?

Courts retain constitutional judicial power, and no administrative agency can insulate itself from judicial review simply by claiming specialized expertise. But that isn’t really the question here. The better question is: at what point does judicial review become judicial substitution?

If every wage order can routinely travel from RTWPB, to wage order, to RTC declaratory relief, to injunction, to prolonged litigation, the specialized administrative system Congress built risks being hollowed out in practice. The institutional line Congress drew is that RTWPB and NWPC handle wage policy and specialized economic determinations, while courts police legality and constitutionality. Judicial review is meant to keep administrative agencies within the law, not to function as a substitute RTWPB or NWPC — a distinction the Court will ultimately have to draw for itself in this case.

The Question That Deserves an Answer

The NCR-27 controversy is ultimately about more than an ₱85 wage increase. It asks whether a general procedural remedy under Rule 63 can be used to bypass a special statutory mechanism that has governed regional wage-setting since R.A. No. 6727 was enacted in 1989.

The pending petition builds a substantial case around Articles 123 and 126, primary jurisdiction, exhaustion of administrative remedies, Rule 63, and the constitutional protection of labor. Article 4 adds one more dimension worth taking seriously. Stated as a general interpretive framework: a clear law is applied as written; a specific remedy like Article 123 is meant to be used, not revived through a different procedural door once its window has closed; an ambiguous provision like Article 126 is read together with the rest of the statutory scheme; and only if genuine doubt survives that exercise does Article 4 direct that it be resolved in favor of labor. Whether that framework — or some other — governs NCR-27 is squarely the Court’s call to make.

Which leaves the question the Court will ultimately have to answer: if Articles 123 and 126 are clear, what was there for the RTC to declare? And if they are genuinely ambiguous, what happens to that ambiguity under Article 4?

The Supreme Court has not yet spoken. Until it does, the arguments in the pending petition remain just that — arguments, not controlling doctrine. But the case gives the Court a real opportunity to define the relationship between declaratory relief and special statutory remedies, between judicial review and administrative expertise, and between judicial intervention and the wage-setting authority Congress deliberately entrusted to the RTWPBs and the NWPC.

Where Engineering Ends and Appraisal Begins: Lessons from the Cost Approach

In the previous article, I discussed the relationship between engineering and appraisal, particularly when valuation involves buildings, machinery and equipment, and other technically complex improvements.

Real estate appraisal is the professional domain of the appraiser. The increasing technical complexity of a property does not change that. What it does change is the nature and extent of the technical evidence the appraiser may need from engineers and other specialists in developing a credible opinion of value. Engineers provide essential evidence about the physical asset — its specifications, capacity, condition, performance, technical life, and replacement requirements.

From Cost to Value: Where Engineering Ends and Appraisal Begins

Understanding the Roles of Engineers and Appraisers in Machinery, Equipment, and Renewable Energy Valuation

The valuation of renewable-energy assets presents an opportunity to revisit a long-standing perception in Philippine valuation practice: that machinery and equipment valuation — and even the Cost Approach in general — is primarily the domain of engineers.

There is an understandable historical basis for this view. Engineers possess the technical expertise to understand buildings, machinery, industrial plants, power-generating equipment, and other specialized assets. They can determine specifications, capacity, physical condition, useful life, construction or replacement requirements, and engineering costs.

But an important distinction must be made: knowing the asset and determining its cost are not necessarily the same as determining its value. This distinction becomes particularly clear when we consider the valuation of a renewable-energy facility such as a wind farm or other assets.

RESA Month Reflection: Economics as the Foundation of Philippine Real Estate Practice

Every August, the Philippine real estate profession celebrates the enactment of the Real Estate Service Act (RESA), a landmark law that professionalized real estate brokerage, appraisal, and consultancy.

The significance of RESA extends beyond licensure. Its Declaration of Policy recognizes that the real estate service profession plays a vital role in national development by promoting the growth of the real estate industry, protecting the public interest, and ensuring that the services rendered by real estate professionals contribute to economic progress through competent, ethical, and globally competitive practice.

The House That Cost More Than It Was Worth

A Lesson on Why Cost Is Not Value

Early in the morning, a fellow appraiser called me, sounding troubled.

“I’ve been asked to authenticate my appraisal report in court,” she said. “The lawyers believe my report is conservative and will prove how much the house cost to build.”

I asked her a simple question.

“What exactly were you hired to do?”

“I was hired to appraise the building,” she said.

From MEPZ III to SM Arena: What the South Road Properties Tell Us About the Philippine Economy

Yesterday, while driving home from southern Cebu, I found myself caught in an unusually heavy traffic buildup along the South Road Properties (SRP). At first, I wondered what was causing the congestion. Moments later, I realized that people were making their way to the grand opening of SM Arena Seaside Cebu.

The Arena is an impressive addition to Cebu’s urban landscape—a 19,000square-meter indoor events venue with a seating capacity of up to 25,000, placing it among the largest event venues in the country. Its opening symbolizes how investment priorities in SRP have shifted over the past three decades—from an industrial growth strategy toward one centered on commerce, tourism, entertainment, institutional uses, and other service-oriented activities.

Beyond the Hotel: Complex Hospitality Valuation in Rehabilitation Proceedings

Open hotel appraisal report showing property overview and financial metrics

One of the privileges of professional practice is the opportunity to work on assignments that challenge not only technical competence but also one’s understanding of economics, law, and property rights.

Our team had the opportunity to undertake two major hospitality valuation assignments in support of corporate rehabilitation proceedings. While confidentiality prevents disclosure of the parties, the engagements involved substantial hospitality assets in Zambales and Tagaytay. They required the application of appraisal principles beyond conventional real estate valuation.

One assignment involved a hospitality development consisting of two five-storey hotel buildings, together with a clubhouse, basement parking, swimming pool, landscaped amenities, function facilities, and more than one hundred individually titled accommodation and commercial units. The complexity of the property required careful analysis of both the physical assets and the legal interests represented by numerous condominium titles.

The second assignment involved another large-scale hospitality village developed on approximately four hectares of land. The property consisted of three multi-storey villa buildings with a combined gross floor area approaching 16,000 square meters, complemented by recreational facilities including a clubhouse, swimming pool, tennis court, landscaped parking areas, and other resort amenities. Unlike the first assignment, however, the underlying land was held under a long-term government lease, requiring the valuation to distinguish between the leasehold interest over the land and the ownership of the buildings and improvements.

These engagements reinforced an important realization.

In complex litigation and rehabilitation proceedings, valuation is no longer about estimating what a property could sell for. It is about understanding what legal rights exist, what economic opportunities those rights create, and how those rights influence value.

Two hotels may appear similar in terms of buildings, rooms, and operations. Yet they may have materially different market values because the underlying property rights differ.

This is precisely why our consulting practice has continued to develop what we refer to as the Evidence-Based Valuation Framework.

Rather than beginning solely with comparable sales, the framework first identifies the property rights involved before systematically examining physical, legal, planning, economic, and market evidence. The final opinion of value is therefore not simply an estimate—it is the conclusion supported by a comprehensive body of evidence.

Assignments such as these demonstrate the expanding role of modern valuation practice. Today’s appraiser is expected not only to measure value but also to explain the legal and economic foundations upon which that value rests. This is particularly important in rehabilitation proceedings, where valuation evidence assists the court, creditors, rehabilitation receivers, and other stakeholders in making informed decisions regarding financially distressed assets.

For us, every engagement is an opportunity to demonstrate that valuation is more than determining a number.

It is the disciplined application of economics, property law, planning, and market evidence to arrive at an opinion that is credible, transparent, and capable of withstanding professional and judicial scrutiny.

The future of valuation lies not merely in producing credible numbers, but in presenting credible evidence.

Each profession performs an indispensable function within the development lifecycle.

Yet, despite the technical competence of these individual disciplines, a fundamental question often remains unanswered: What development decision creates the greatest long-term economic value?

This question cannot be answered by valuation alone, nor can it be resolved by engineering, planning, law, or finance acting independently. It requires economics.
