When you finance a home, the lender wants proof that the property is worth what you agreed to pay. That proof is an appraisal, an independent estimate of value performed by a licensed professional. It protects the lender's collateral, and it can reshape your deal if the number disappoints.
Why lenders order an appraisal
A mortgage is secured by the home, so the lender needs assurance it could recover its money if you defaulted. The appraisal confirms the property supports the loan amount and sets the loan-to-value ratio, which affects your rate and whether you need mortgage insurance. To keep it unbiased, the lender typically orders the appraisal through a third party rather than choosing the appraiser directly. The buyer usually pays the fee, often a few hundred dollars, as part of closing costs.
How value is estimated
For most homes, appraisers rely on the sales comparison approach, looking at recent sales of similar nearby properties. They adjust those comparable sales for differences in size, condition, upgrades, and location to arrive at a supported value. Condition, square footage, and the quality of recent comparable sales carry the most weight. The result is an opinion of value grounded in the market, not a guarantee of what a buyer would pay.
When the appraisal comes in low
If the appraisal is below the contract price, the lender will only finance against the lower number, leaving an appraisal gap. Buyers can respond by bringing extra cash to cover the gap, renegotiating the price with the seller, disputing the appraisal with better comparable sales, or walking away if they have an appraisal contingency. A low appraisal is a common friction point in competitive markets where offers outrun recent sales. How you handle it depends heavily on the contingencies in your contract.
You agree to buy a home for 350,000 dollars, but the appraisal comes back at 335,000 dollars. The lender will lend only against 335,000 dollars, so you either negotiate the price down, pay the 15,000 dollar gap in cash, or use an appraisal contingency to exit.
Key takeaways
- An appraisal is an independent value estimate that protects the lender's collateral.

Can I challenge a low appraisal?
Yes. You can submit a reconsideration of value with stronger comparable sales or point out factual errors, though there is no guarantee the number changes.
