The Appraisal Process (and Low Appraisals)
Somewhere between your accepted offer and the closing table, a licensed stranger decides whether the house is worth what you agreed to pay. That's the appraisal — and a low one can put an otherwise-done deal at risk.
What it is and why lenders require it
An appraisal is an independent, licensed appraiser's opinion of a home's market value, ordered by the lender. The lender won't hand you a loan that's large relative to what the property is actually worth, because the home is its collateral. The appraisal both protects the lender and sets your true loan-to-value — which, if it comes in high, can even affect your PMI and pricing.
How the value is formed
The appraiser leans mainly on recent comparable sales — "comps" — of similar nearby homes, adjusting up or down for size, condition, and features. It's backward-looking by design: it measures what the market has recently paid, not what a bidding war says today. In a fast-rising market, that lag is exactly what produces a low appraisal.
When it comes in low
A value below your contract price isn't automatically a dealbreaker — it's a negotiation with several exits:
- Renegotiate the price down to the appraised value.
- Bring extra cash to cover the gap between price and value.
- Split the difference with the seller.
- Request a reconsideration of value (ROV) with stronger comps the appraiser missed — or, in some cases, order a second appraisal or move to another lender.
Appraisal gap coverage
In hot markets, buyers sometimes agree upfront to cover a shortfall up to a stated cap — "appraisal gap coverage" — to make an offer more competitive. It can win the house, but you're promising real cash if the value falls short, so know the number you're committing to. Remember the appraisal fee is part of your closing costs, and the value it sets feeds straight into whether your loan is conforming or jumbo.
Common questions
Why do lenders require an appraisal?
The home is the lender's collateral, so it won't lend more than the property is worth. The appraisal protects the lender and sets your true loan-to-value, which can affect your pricing and PMI.
What happens if the appraisal comes in low?
It's a negotiation, not a dealbreaker. You can renegotiate the price down, bring extra cash to cover the gap, split the difference with the seller, or request a reconsideration of value with stronger comps.
How does an appraiser decide the value?
Mainly from recent comparable sales of similar nearby homes, adjusted for size, condition and features. It's backward-looking by design, which is what produces low appraisals in a fast-rising market.
What is appraisal gap coverage?
A buyer's upfront promise to cover a shortfall up to a stated cap, used to strengthen an offer in a hot market. It can win the house, but it commits you to real cash if the value falls short.
