Houses usually do sell at or near their appraised value. In the second half of 2024, appraisals came in at or above the contract price in roughly 93% of transactions, and only about 8% produced an appraisal below the sale price. That still leaves room for gaps of thousands of dollars, and what happens when the two numbers diverge depends on your loan type, your contract, and what the local market is doing.
Why the Two Numbers Rarely Match Exactly
A sale price is whatever a buyer and seller agree to. An appraised value is an independent estimate prepared by a licensed professional following the Uniform Standards of Professional Appraisal Practice.1The Appraisal Foundation. USPAP – Uniform Standards of Professional Appraisal Practice The two figures answer different questions, so perfect alignment would actually be a coincidence.
The appraiser builds the estimate from comparable sales, meaning recent transactions involving similar homes nearby. Fannie Mae’s guidelines call for comparables that closed within the previous 12 months, though appraisers generally prefer the most recent sales available.2Fannie Mae. Comparable Sales Adjustments are made for differences in square footage, lot size, condition, and features. Because the analysis relies on closed transactions, the appraisal is inherently backward-looking.
A buyer’s offer reflects real-time motivation: how badly they want the house, how many other bidders they’re competing against, and whether the neighborhood has a specific draw like a strong school district. A home might appraise at $350,000 while a buyer willingly pays $365,000 to beat five other offers. A seller might accept $340,000 because they need to relocate quickly. Neither result means the appraisal was wrong. It means the appraisal and the negotiation measured different things.
Market Conditions Widen or Shrink the Gap
In a seller’s market with low inventory and multiple offers, sale prices routinely overshoot appraised values. Bidding wars don’t wait for appraisers to catch up, and the comparable sales feeding the report may already be months stale. This is where appraisal gaps become a regular problem rather than a rare surprise.
In a buyer’s market, the direction flips. When homes sit listed for 60 or 90 days with few offers, sellers often accept prices below what the appraisal suggests. The appraiser’s comps may still reflect a stronger period from earlier in the year, producing a value that looks optimistic compared to what buyers are currently paying. Rising interest rates accelerate this: higher monthly payments shrink purchasing power even if home values haven’t technically dropped.
Seasonality plays a role too. Spring listings tend to sell at higher premiums because buyer demand surges before summer, and appraisers may only have winter closings to work from. By late fall, the pattern reverses. The core dynamic is simple: the appraisal looks in the rearview mirror while the sale price reflects the road ahead.
How Lenders Treat the Appraisal
For any financed purchase, the appraisal exists to protect the lender. Fannie Mae and Freddie Mac require lenders to obtain an appraisal confirming the property’s market value before funding a mortgage.3Fannie Mae. Appraisers
The rule that matters most at the closing table: lenders calculate the loan amount based on the lower of the appraised value or the purchase price. If you agree to buy a home for $420,000 but the appraisal comes back at $400,000, the bank treats $400,000 as the property’s value. On an FHA loan requiring 3.5% down, that means your minimum down payment is calculated against $400,000, not the $420,000 you offered.4Consumer Financial Protection Bureau. FHA Loans You’d still have to cover the $20,000 gap between the appraised value and the purchase price, on top of your down payment and closing costs.
Appraisals also have a shelf life. Under Fannie Mae guidelines, an appraisal is valid for 12 months from its effective date, but if more than four months pass before closing, the lender must order an appraisal update that includes a property inspection and current market data review. If that update shows a decline in value, a brand-new appraisal is required.5Fannie Mae. Appraisal Age and Use Requirements For deals that drag on, you can end up paying for the appraisal process twice.
When the Appraisal Comes In Low
A low appraisal is probably the most stressful outcome in a home purchase, and it happens in roughly 8% to 10% of deals. The lender won’t increase the loan to cover the shortfall, so somebody has to give. Buyers generally have four options:
- Ask the seller to lower the sale price to match the appraised value. Sellers in a soft market are more likely to agree; sellers holding backup offers rarely budge.
- Pay the difference in cash, on top of your down payment.
- Negotiate a compromise where the seller drops the price partway and you bring extra cash for the remainder.
- Walk away. If your contract includes an appraisal contingency, you can cancel the deal and get your earnest money deposit back, typically 1% to 3% of the purchase price.
Most purchase contracts include an appraisal contingency by default. This clause makes the sale conditional on the property appraising at or above the contract price, giving the buyer a window to renegotiate or terminate without forfeiting the deposit. Waiving the appraisal contingency, which became common during the ultra-competitive markets of 2021 and 2022, removes that safety net entirely and puts the buyer on the hook for any shortfall.
Appraisal Gap Clauses
In competitive markets, buyers sometimes include an appraisal gap clause to strengthen their offer. This is a pre-commitment: you agree upfront to cover a shortfall between the appraised value and the purchase price, up to a specific dollar limit. If you offer $650,000 with a $25,000 appraisal gap clause and the property appraises at $630,000, you bring that $20,000 difference in cash and the deal closes at $650,000. If the gap exceeds your stated limit, the parties renegotiate or walk. The clause tells sellers a low appraisal won’t kill the deal, which can lift your offer above competing bids that don’t include one.
When the Appraisal Comes In High
A high appraisal is straightforward good news, but it changes less than people assume. If you agree to buy a home for $400,000 and it appraises at $420,000, the lender still bases your loan on the $400,000 purchase price. You don’t borrow more money, and your required down payment stays the same.
What you do get is instant equity. On day one, you own a home worth $20,000 more than you paid. That cushion moves you toward 20% equity faster, which is the threshold where you can typically request removal of private mortgage insurance. If property values keep rising, a buyer who started with built-in equity reaches that milestone earlier than one who bought at appraised value. The seller might wonder whether they left money on the table, but the appraisal isn’t published to the market and doesn’t obligate anyone to adjust the price.
Challenging a Low Appraisal
If you believe the appraisal undervalued the property, you’re not stuck with the number. Both Fannie Mae and Freddie Mac allow a formal process called a Reconsideration of Value (ROV), where the borrower submits evidence through the lender asking the appraiser to revisit the conclusion.6Fannie Mae. Reconsideration of Value (ROV) You get one shot per appraisal report, so it needs to count.
The strongest ROV requests focus on what the appraiser missed or got wrong: comparable sales that are more similar to the property than the ones used, factual errors in the report such as wrong square footage or a missed renovated bathroom, or recent sales the appraiser may not have had access to. Vague objections like “we feel the home is worth more” go nowhere. If the appraiser agrees the new evidence changes the analysis, they update the report. If not, they document why the value stands.
FHA had briefly established its own uniform ROV process in 2024 but rescinded that guidance in March 2025. FHA borrowers can still request a reconsideration through their lender, but the process now follows the lender’s own policies rather than a standardized FHA framework.
Cash Purchases Are a Different Story
When no mortgage is involved, no lender requires an appraisal. Cash buyers can skip the process entirely, which is one reason cash offers are attractive to sellers: there’s no risk of an appraisal gap tanking the deal. Sale prices in all-cash transactions can deviate significantly from what an appraiser would conclude, in either direction, because the only constraint is what the buyer is willing to spend.
Even so, many cash buyers order an appraisal anyway. Spending a few hundred dollars to confirm you aren’t overpaying by tens of thousands is cheap insurance. The appraisal also creates a baseline for property tax appeals, insurance coverage, and future refinancing. Skipping it saves time but removes the only objective check on the price you agreed to pay.
