My Construction Costs Came in Higher Than the Appraisal
Your construction costs are higher than what the appraisal supports. This is a real problem with real solutions — but only if you address it honestly and immediately rather than hoping the gap disappears on its own. Here is what the gap means, why it happens, and what your options actually are.
Construction Costs Higher Than the Appraisal — Understanding What This Actually Means
When your construction costs come in higher than the appraised after-construction value supports, you have what the industry calls an appraisal gap — a situation where the total cost to complete the project exceeds what the market says the finished product will be worth. This gap has a direct and immediate effect on your construction loan: it reduces the amount the lender can advance, because private construction lenders are constrained by both loan-to-cost limits and loan-to-ARV limits simultaneously. Both must be satisfied. If the cost has grown past what the exit value supports, one of those limits — usually the 75% loan-to-ARV cap — begins to constrain the loan amount below what the project actually needs.
Understanding this constraint precisely is important because it determines which of your available options will work. The gap between what your costs are and what your loan can support is a specific number. Knowing that number — and being honest about it — is the starting point for every conversation about how to address it.
Why This Gap Happens — and Why It Is More Common in Premium Markets
The appraisal gap between construction costs and exit values is most common in two situations. The first is when construction costs have risen faster than comparable sale prices in a specific market — a dynamic that affected many New England markets between 2022 and 2024 as material and labor costs spiked while transaction volumes fell. The second is when a developer has proposed a finish specification that is more expensive than what the local comparable sales support — building a $600 per square foot home in a market where buyers are only paying $450 per square foot for new construction.
In premium Massachusetts markets like Newton, Lexington, and Weston, this problem is relatively rare because the exit values are high enough to support the construction costs. In emerging markets where exit values are still developing relative to construction costs — some Route 495 communities and selected South Shore towns — the gap appears more frequently and requires more careful underwriting. In both cases, the solution requires either reducing costs, demonstrating a higher exit than the appraisal captured, or bringing additional equity to the transaction.
Your Options When Construction Costs Exceed What the Appraisal Supports
There are four genuine paths forward when you face a construction cost and appraisal gap. Each one has different implications for the project economics and different levels of difficulty to execute. Understanding all four allows you to choose the approach that best fits your specific situation.
