Appraisal contingencies protect you from overpaying for a home when the bank won't back the purchase price. Understanding how they work—and what happens when they fail—can save you thousands and keep your deal from falling apart at closing.
What Is an Appraisal Contingency?
An appraisal contingency is a clause in your purchase contract that lets you walk away (or renegotiate) if the home appraises for less than the agreed purchase price. Your lender won't loan more than the property is worth, so if the appraiser finds the home is worth $350,000 but you're buying for $380,000, the contingency gives you an exit or leverage to renegotiate.
Without this protection, you'd be forced to cover the gap in cash or lose your earnest money deposit if you back out. It's one of the most critical safeguards in a residential purchase.
How the Appraisal Process Works
Once your offer is accepted, your lender orders an independent appraisal, typically costing $400–$700 depending on the property size and location. The appraiser inspects the home, compares it to recent sales of similar properties (comps), and assesses condition, updates, and market trends. This process usually takes 7–10 business days.
The appraiser is hired by the lender, not you, so they're incentivized to be unbiased—their license depends on it. They'll produce a detailed report showing their valuation methodology and supporting data.
When an Appraisal Comes in Low
If the appraisal is lower than your offer price, you have three main options:
- Renegotiate the price down – Ask the seller to lower their asking price to match the appraised value. Many sellers will negotiate rather than lose the deal entirely.
- Request a second appraisal – If you believe the first appraisal was inaccurate, you can ask for (and sometimes pay for) a second opinion. Lenders won't always agree to this, and it adds 1–2 weeks to your timeline.
- Make up the difference in cash – Pay the gap yourself if you have the funds and the lender approves. This is rare for owner-occupied purchases but more common with investors.
- Walk away – If your appraisal contingency allows it, you can exit without losing your earnest money, though this kills the deal.
Red Flags When Hiring an Appraiser (for context)
If you're commissioning a residential appraisal for refinancing or estate purposes, make sure the appraiser is state-licensed and has at least 2–3 years of recent experience in your specific market. Check that they don't have a history of pressure from lenders to artificially inflate or deflate values. Reputable appraisers will provide transparent methodology and detailed comparables.
Platforms like Mercoly help you compare and find trusted residential appraisal providers in one place, so you can verify credentials and read reviews before committing.
Contingency Language Matters
The strength of your appraisal contingency depends on exact contract wording. Some contracts allow you to terminate if the appraisal is any amount below the offer; others only trigger if it's below the loan-to-value threshold your lender sets (typically 80%). Review your specific contingency clause with a real estate attorney—the difference can cost you $10,000–$50,000.
Timeline and Deadlines
Your contract will set a deadline to waive or invoke the appraisal contingency, usually 10–15 days after the appraisal report is delivered. Missing this deadline can forfeit your right to renegotiate or exit based on appraisal results. Mark this date on your calendar and stay in touch with your lender and real estate agent.
Protecting Yourself
- Request the appraisal early in the closing process so you have time to respond if needed.
- Attend the appraisal (if permitted) to point out recent upgrades the appraiser might miss.
- Provide the appraiser with a list of recent comparable sales in the neighborhood.
- Have your agent review the draft appraisal for obvious errors before the final report.
Frequently Asked Questions
Q: Can I challenge a low appraisal? Yes, you can submit a formal appraisal appeal (usually free) with supporting evidence like comparable sales, recent improvements, or documentation of market conditions. Your lender or real estate agent can guide you through the process, though the outcome isn't guaranteed.
Q: What if I waive my appraisal contingency? Waiving it means you're committed to the purchase price regardless of appraisal results—you'll cover any gap in cash or lose your earnest money if you back out. This is risky in slower markets where appraisals are more likely to come in low.
Q: How long does an appraisal usually take? Most residential appraisals take 7–10 business days from order to final report, though rush appraisals (for $50–$150 extra) can sometimes be completed in 3–5 days if your lender expedites.
