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.
Not to audit construction costs. Not to verify contractor billings. Not to determine how much the owners actually spent. Simply to appraise the improvement.
That distinction, small as it sounded on the phone, would turn out to be the heart of the entire dispute.
The Assignment
Months earlier, she had inspected a newly completed two-storey residence. The owners had also commissioned an architect to prepare a Bill of Materials and Cost Estimate. According to that estimate, constructing the house would cost approximately Php3.95 million.
During her inspection, she observed something different. The building was new, but several workmanship deficiencies were evident — portions of the finishes showed premature deterioration, and some construction details reflected workmanship below what would ordinarily be expected of a newly completed residence.
She documented what she saw. She didn’t discard the architect’s estimate — she accepted it as the starting point of her valuation, then asked the question every appraiser is trained to ask: what is the present contributory value of this building, in its current condition?
Applying the cost approach, she recognized that the building no longer carried the same utility as a defect-free improvement, and an effective depreciation adjustment was warranted. After that adjustment, she concluded that the building contributed approximately Php3.55 million to the property’s value.
Her assignment was complete. Or so she thought.
The Letter
Months later, a lawyer contacted her. A construction dispute had reached the courts, and he wanted her to execute a Judicial Affidavit authenticating her report.
The request seemed straightforward — until she read the letter more closely. The lawyer’s language explained that her appraisal would establish “the true value of the improvements” in the pending litigation.
That phrasing raised an important question, and it’s the same one she brought to me on the phone: did her appraisal establish construction cost, or did it establish market value? Those are not the same thing, and the Php400,000 gap between the architect’s number and hers was about to become a courtroom issue built entirely on that confusion.
Many people assume that if a building costs Php3.95 million to construct, it must also be worth Php3.95 million. Real estate doesn’t work that way. Construction cost is an expenditure. Market value is an economic opinion. The difference is subtle on paper and enormous in practice.
An architect asks: how much should this building cost to construct? An appraiser asks: what is this building worth today? Those are entirely different questions — and this particular misunderstanding shows up constantly, not only in courtrooms but in negotiations, insurance claims, expropriation cases, and tax assessments. People equate expenditure with value all the time. Professionals, unfortunately, sometimes do too.
Two Warehouses
I explained it to her the way I explain it to most people who’ve never had to think about it before — with a picture rather than a definition.
Imagine two industrial warehouses, each with a loading platform measuring one hundred square meters. From a distance, they look identical. One platform was built only for light delivery vehicles. The other was engineered to carry fully loaded container trucks.
An engineer notices the difference in construction immediately. An appraiser asks something else: does that added structural capacity create additional economic utility that the market actually recognizes and pays for?
If both warehouses serve only neighborhood delivery vans, the stronger platform offers little benefit. It cost considerably more to build, but buyers won’t pay more for capacity they’ll never use.
Now move both warehouses into a logistics park where container trucks arrive every day. Suddenly the stronger platform matters. It supports heavier loads, attracts industrial tenants, and improves operational efficiency. The market recognizes that utility, and the value follows.
The increase in value doesn’t come from the extra concrete that was poured. It comes from the extra economic benefit the improvement produces. That’s the distinction appraisers are trained to see, and it applies far beyond warehouses.
I gave her a second example, one closer to her own case. Picture two mid-rise office buildings with identical floor plates, identical curtain walls, identical HVAC systems — a contractor would price them the same to build. But suppose only one has a backup generator large enough to run the building through a power outage. In a market where tenants pay a premium for guaranteed uptime — law firms, clinics, anyone who can’t afford downtime — that generator adds real value. In a market where tenants shrug at outages, it might add almost nothing beyond what it cost to install. Same expenditure, same specification, two very different values, depending entirely on what the market is willing to pay for.
And it isn’t only commercial property. I mentioned a case I’d seen once where a homeowner spent roughly Php2 million on a full custom kitchen renovation — imported stone, professional-grade appliances, custom cabinetry — expecting the house to be worth Php2 million more. Buyers in that neighborhood were willing to pay perhaps Php500,000 more for it. The rest was real money, spent and gone, but never converted into value the market would recognize. An over-improvement, in appraisal terms — and a very common one.
Why She Looked at the Details She Did
She asked me something else during that call, something she said lawyers ask her often: why bother examining construction details at all, if not to price the building?
It’s not because appraisers are engineers. She wasn’t expected to determine slab thickness through structural testing, and no judge would expect that of her either. Her responsibility was narrower and, in a way, harder — to identify, verify, or reasonably ascertain the physical characteristics of the building that were likely to affect what it was worth.
Where those characteristics were visible, she observed them directly during inspection — which is exactly what accounted for the deficiencies she’d noted and the depreciation she’d applied. Where they weren’t visible, an appraiser leans on construction plans, engineering drawings, specifications, and permits. What she was never doing, at any point, was counting concrete or pricing materials. She was asking whether what she saw and verified changed what a buyer would actually pay for the house.
What Her Report Actually Said
By the end of the call, she’d talked herself into the answer she already had in her hands. Her report never claimed to determine how much money the owners had spent constructing the house. It answered a different question entirely — an opinion of the building’s contributory value, after accounting for its condition on the date of inspection. That’s exactly what an appraisal is supposed to do. No more, no less.
The lawyer’s letter had conflated two different documents, expecting her appraisal to do a construction estimate’s job. It’s an easy conflation to make and a costly one to leave uncorrected on the stand.
The Broader Lesson
There’s a lesson here for more than just appraisers — for lawyers, engineers, judges, and property owners alike. Construction estimates, contractor billings, engineering reports, and appraisal reports are all legitimate, useful documents. But they are not interchangeable, because each answers a different question. A construction estimate answers what should it cost to build? An engineering report answers what was built, and how? An appraisal answers what is it worth in the market?
Treating any one of these as proof of another is where misunderstanding creeps in — and where, as my colleague discovered, misunderstanding can quietly become litigation.
Final Thought
One lesson has guided the appraisal profession for generations: engineers design structures, contractors build them, quantity surveyors estimate their cost, accountants record expenditures, and appraisers estimate value.
They all begin with the same building. They simply end at different destinations.
Because in appraisal, cost explains how a building came into existence. Value explains what that building is worth.
