New Construction Appraisal Gaps in 2024: When the Builder's Price and the Bank's Value Disagreed

National data released in early 2025 covering 2024 construction costs showed something builders had been feeling for a while: the finished lot, labor, and materials that go into a new home had climbed to a record 64.4% of the sales price, up from roughly 60.8% just two years earlier. That increase — driven by ongoing inflation in building materials and labor — put real upward pressure on what builders needed to charge to maintain their margins, even as buyer demand was getting more price-sensitive under elevated rates.

Where that created friction at the appraisal stage

An appraiser values a new home largely based on recent comparable sales — other homes, ideally similar new construction, that have closed nearby. In communities where a builder had recently raised prices to reflect higher input costs, but where the comparable sales an appraiser had to work with were from homes that closed a few months earlier at the old, lower price point, a gap could open up between what the builder was asking and what the appraisal supported.

This wasn't universal — in fast-moving communities with steady sales pace, comps caught up quickly. But in communities where sales had slowed under the weight of elevated rates, or where a builder had pushed pricing ahead of what the immediate comps could justify, buyers financing a home ran a real risk of an appraisal coming in under contract.

What buyers could do about it

A few practical habits mattered in this environment. First, asking the builder directly whether recent sales in the specific section or phase support the current asking price, rather than assuming the sales office's number is automatically appraisal-safe. Second, building an appraisal gap clause into the contract where possible — language addressing what happens, and who covers the difference, if the appraisal comes in low, rather than discovering there's no plan for that scenario at the closing table. Third, for buyers with some flexibility, timing a purchase toward the start of a new phase release, where builders sometimes priced more conservatively to build sales momentum, rather than the final few lots in a phase where pricing had already climbed.

The bigger picture

Rising construction costs are a structural trend, not a one-year event, and the appraisal friction that showed up in 2024 is a preview of a dynamic likely to recur whenever builder pricing moves faster than the comparable sales data appraisers rely on. Buyers under contract on new construction should treat the appraisal stage as a real risk to plan for, not a formality to assume will resolve itself.
