A new construction appraisal values a home that does not fully exist yet. The appraiser works from the plans, specifications, and lot — issuing a value "subject to completion" — and then returns near the end of the build to certify the finished home matches what was appraised. It is the same appraisal you would get on a resale home, split into a before and an after.
What the appraiser reviews before the home exists
For a subject-to-completion appraisal, the appraiser is handed a package instead of a house:
- Plans and specifications: floor plans, elevations, square footage, and the materials/finish list.
- The purchase contract or construction contract, including options and upgrades.
- The lot: location, size, and site characteristics.
- Comparable sales: recently sold homes of similar size and quality — in new subdivisions, often other closings by the same builder; for custom homes, the appraiser looks wider.
The "subject to completion" report
The initial report states the home's value as if it were already finished according to the plans. That hypothetical is the number your loan is underwritten against — it drives your loan-to-value calculation just as a walk-through appraisal would on a resale home.
On a construction-to-permanent loan, this appraisal happens before closing, since the lender needs the completed value before funding the build. On a production build with builder financing, it is ordered during your normal loan processing window closer to completion.
The final inspection (Form 1004D)
When construction wraps, the appraiser returns to certify completion — commonly documented on Form 1004D. They confirm the home was built substantially according to the plans the value was based on. If items are incomplete or changed, the appraiser notes it, and the lender may hold funds or require completion before closing.
This is separate from the municipal certificate of occupancy and separate from the draw inspections that happen throughout a construction loan. A new build can involve all three kinds of inspection, each answering a different question.
Why upgrades don't always equal appraised value
Design-center upgrades are priced at retail by the builder; appraisers value them by market reaction. Structural options — an extra bedroom, a third-car garage — tend to hold appraised value well. Finish upgrades — countertop tiers, flooring packages, lighting — often contribute less appraised value than they cost.
This does not make upgrades wrong; it makes them a consumption decision as much as an investment decision. Plan your cash accordingly — upgrade deposits interact with your down payment, which we cover in down payment on new construction.
What happens if the appraisal comes in low
A low appraisal means the loan is sized against the appraised value rather than the contract price, which changes your cash-to-close math. Your options are the same as on a resale purchase, with a builder twist:
- Renegotiate: builders protect their community pricing and rarely cut base price, but they often bridge gaps with incentives or included options instead.
- Challenge the appraisal: a reconsideration of value with better comparable sales sometimes succeeds, especially in fast-moving new communities where closings lag the market.
- Bring the difference in cash, if the gap is small and you want the home.
- Walk away — check your contract's appraisal contingency language before signing, because builder contracts handle this differently than standard resale contracts.
Timing the appraisal in a long build
Appraisals have shelf lives, and long builds can outlive them. If a build runs past the appraisal's validity window, the lender orders an update — and in a shifting market, updated values can move in either direction. This is one more reason the rate lock and timeline strategy on a new build deserves real attention before contract, not after.
Frequently Asked Questions
How can an appraiser value a home that isn't built?
They appraise it "subject to completion" using the plans, specifications, lot, and comparable sales — producing the value of the home as if finished according to those plans. A final inspection at completion certifies the home matches what was appraised.
Do I pay for two appraisals on a new build?
Usually it is one appraisal assignment with two parts: the initial subject-to-completion report and the final completion certification. If a build runs very long and the report expires, an appraisal update may be required.
Will my upgrades increase the appraised value?
Structural options generally contribute the most appraised value. Cosmetic and finish upgrades often appraise for less than their design-center price. Treat finish upgrades as a lifestyle expense first and an investment second.
What if my new home appraises below the purchase price?
The loan is based on the lower of price or appraised value, so a gap means renegotiating with the builder, challenging the value with better comps, bringing extra cash, or exercising your contingency. Builders often bridge gaps with incentives rather than price cuts.
