The Appraisal Process (and Low Appraisals)

Last updated August 24, 2026

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:

A low appraisal is a math problem, not a verdict. The only figures that matter are the size of the gap and who absorbs it — walk each option before you panic or quietly agree to overpay.

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.
