How to Understand Appraisal Contingencies When Buying a Home and Protect Your Earnest Money

What Is an Appraisal Contingency?

When you make an offer on a home, your lender will require an independent appraisal to confirm that the property is worth at least the amount you have agreed to pay. An appraisal contingency is a clause in your purchase contract that gives you specific rights if the appraisal comes in below the agreed purchase price. Depending on how the contingency is written, it may allow you to renegotiate the price, request that the seller make up the difference, or walk away from the deal entirely with your earnest money returned.

Appraisal contingencies are standard in most purchase contracts, but in competitive markets they are sometimes waived by buyers who want to make their offer more attractive to sellers. Understanding exactly what you give up when you waive this protection is essential before agreeing to do so.

How an Appraisal Shortfall Works

Suppose you offer $500,000 for a home and the seller accepts. Your lender orders an appraisal, and the appraiser values the property at $480,000. This $20,000 gap — called an appraisal gap or shortfall — creates a problem. Lenders will typically only finance up to a percentage of the appraised value, not the purchase price. If your loan-to-value ratio was already at its maximum, you would need to cover the $20,000 difference in cash to keep the deal alive.

With an appraisal contingency in place, you have options. You can ask the seller to reduce the price to $480,000. You can negotiate a split, where each party covers part of the gap. You can walk away and get your earnest money back. Or, if you have the cash available and want the home badly enough, you can proceed and cover the gap yourself. The contingency gives you the choice — without it, you are contractually obligated to close regardless of the appraisal outcome.

Key Terms to Look For in Your Contract

Not all appraisal contingencies are written the same way, so it is important to read the specific language in your contract carefully. Some contingencies state that the buyer may terminate only if the appraisal comes in below a specific floor price rather than the full purchase price. Others include appraisal gap coverage language, where the buyer agrees in advance to cover a defined amount above the appraised value before the contingency can be invoked.

Pay attention to the contingency deadline as well. Most appraisal contingencies require the buyer to notify the seller in writing within a specific timeframe after receiving the appraisal report. Missing this deadline can result in the contingency expiring, which means you could lose your earnest money if you back out later.

When Waiving the Appraisal Contingency Makes Sense

In highly competitive markets, some buyers choose to waive the appraisal contingency to make their offer stand out. This strategy makes the most sense when you are making a substantial down payment, are confident in the home's market value based on your own research, and have sufficient cash reserves to cover a potential appraisal gap without financial strain.

Buyers who are financing with a small down payment and tight cash reserves should think twice before waiving this protection. A low appraisal in that scenario can create a serious financial crisis and potentially cost you your earnest money if you cannot close.

How to Challenge a Low Appraisal

If your appraisal comes in low, it is not necessarily final. You have the right to request a reconsideration of value from the appraiser, providing evidence of comparable sales that support a higher valuation. You can also request a second appraisal from a different appraiser, though your lender may not accept it. Your real estate agent should assist in pulling strong recent comparable sales to support your case. Low appraisals due to appraiser error or inadequate comparable selection can often be successfully challenged.
