Valuing a house that does not exist
The assignment is to say what a property will be worth when it is finished, using the plans and the specification as the description of what will exist.
That is a hypothetical condition — something known to be untrue right now, assumed deliberately because the question requires it. USPAP requires it be disclosed on the face of the report, not tucked into a paragraph. A subject-to-completion appraisal that does not say prominently that the property was valued as though complete is a defective report, whatever the number says.
Everything downstream depends on the specification. A complete one — finishes, systems, fixtures, allowances — produces a valuation you can rely on. A vague one produces a vague valuation dressed up as a precise one, which is worse.
Two visits, and the second one matters
The first report values the house on paper. Once it is built, a completion report confirms it was built as described, which is what the lender needs before releasing the balance of the money.
That second visit is not a formality. What was specified and what got built come apart more often than builders like to admit: the kitchen package downgraded against an allowance, the finished bonus room that stayed unfinished, the covered porch that became a slab. Where that happens it gets reported, because the first number was conditioned on the specification and the condition was not met.
Both visits are quoted together up front so the second one is not a surprise line on an invoice three months later.
Cost is not value, and here is where you see it
This is the conversation that goes badly on new construction, so it is worth having early.
Cost is what it took to produce the house. Value is what a buyer would pay for it. On a tract build in a subdivision of similar houses those track each other closely. On an infill lot in an established neighbourhood — which is most new construction across Bergen and Passaic — they can separate substantially.
A house that materially exceeds its street will not return the full spend, because the buyer pool for that street does not pay that much regardless of what it cost to build. That gap is external obsolescence: it comes from outside the property and outside the owner’s control, it is measurable from sales, and it is a real finding rather than an opinion about the build quality.
Nobody enjoys hearing it. It is considerably better heard before the framing goes up than at a refinance three years later.
What I need before starting
Final plans and a complete specification. The builder’s contract. The allowance schedule, where there is one, because an allowance is a placeholder rather than a finish and the difference shows up in the valuation.
And the site. A tear-down and rebuild is valued with the demolition and site work reflected rather than assumed away, and those costs vary enough between municipalities in this area to be worth getting right.
If the design is still moving, wait. An appraisal written against a set that changes afterwards describes a house nobody is building, and the lender will return it.
New Jersey specifics
- Infill construction on a subdivided lot is the common case across Bergen and Passaic, and it raises a question a suburban tract build does not: whether the finished house fits the street it is being built on.
- A new house that materially exceeds its neighbours can hit external obsolescence — the market will not return the full cost of what was spent, and the report has to say so even where nobody wants to hear it.
- Tear-down and rebuild sites are valued with the demolition and site work reflected rather than ignored, and those costs vary enough between municipalities to matter.
What you receive
