Home Appraisal Explained for Buyers and Sellers

Quick answer

A home appraisal is a lender-ordered opinion of value used to support the mortgage. If the appraisal is lower than the contract price, the buyer and seller may need to renegotiate or solve an appraisal gap.

An appraisal can become one of the most important steps between offer acceptance and closing. It helps the lender decide whether the home supports the loan amount.

Buyers and sellers should understand appraisal risk before negotiating price, credits, and contingencies.

What an appraiser reviews

The appraiser considers the property and recent comparable sales. Condition, size, location, upgrades, lot, and market activity all matter.

  • Comparable sales
  • Square footage
  • Condition
  • Location
  • Lot size
  • Bedroom and bathroom count
  • Updates
  • Market trends

Why appraisals can come in low

A low appraisal can happen when the contract price is ahead of recent sales, the comparable sales are weaker, or the property has condition issues.

  • Rapid price changes
  • Few comparable sales
  • Overbidding
  • Condition problems
  • Unique property type
  • Neighborhood differences

Options after a low appraisal

The available options depend on the contract, financing, cash available, and willingness of both sides to adjust.

  • Renegotiate price
  • Buyer brings more cash
  • Seller credit or adjustment
  • Challenge appraisal
  • Cancel if allowed
  • Change loan strategy

Prepare before the appraisal

Sellers can provide access and a clean home. Agents may provide relevant comparable sales, improvements, and property information.

  • List upgrades
  • Share permits if available
  • Provide comparable sales
  • Make access easy
  • Address obvious condition issues
