The Appraisal and Appraisal Gap
The Appraisal and Appraisal Gap
An appraisal is an independent, professional assessment of a home's market value, ordered by your lender to ensure the property is worth the mortgage they're about to issue. When the appraisal is lower than your purchase price, you face an appraisal gap—a shortfall you must cover with cash or renegotiate away.
Key takeaways
- Appraisals cost $400–$600 and take 7–14 days; they are ordered by the lender, not by you, and the appraiser works for the bank, not the buyer.
- The appraiser compares the subject property to recent sales of similar homes (comps) and adjusts for differences in size, condition, and features.
- A typical appraisal gap of 2–5% of purchase price can be closed with a price reduction or a seller credit; larger gaps may signal you overoffered.
- Appraisals are subjective; if you believe the appraisal is wrong, you can request a reappraisal, but this costs time and money.
- Waiving an appraisal contingency means you must close even if the appraisal is low—a risky move unless you have substantial cash reserves and conviction about the property's true value.
How appraisals work: the methodology
Your lender orders an appraisal as a condition of the mortgage. The appraiser is a licensed professional who receives no compensation based on the outcome—federal law prohibits this to prevent bias. The appraiser's job is to determine the property's fair market value, independent of what you offered to pay.
The appraisal process works like this:
- The lender orders the appraisal and provides the appraiser with your offer price and the property address.
- The appraiser inspects the property, noting condition, upgrades, deferred maintenance, and functional features.
- The appraiser researches recent sales of similar homes in the same neighborhood and surrounding areas (comparables, or "comps").
- The appraiser adjusts each comp for differences: if a comp sold for $350,000 but is 500 square feet smaller than your subject property, the appraiser might add $20,000 for the size difference. If a comp has a pool and your property doesn't, the appraiser subtracts $15,000.
- The appraiser produces a written report with the appraised value, supporting comps, and a detailed explanation of adjustments.
The appraiser typically aims for an objective, defensible number. But appraisals are not scientific. Two appraisers examining the same property might value it $15,000–$30,000 apart, depending on which comps they emphasize, how they adjust for differences, and how they weigh the property's condition and location.
What causes an appraisal gap
An appraisal gap occurs when the appraised value is lower than the purchase price. You offer $400,000; the appraisal comes in at $385,000. The gap is $15,000.
Several factors cause gaps:
You offered too much. In a competitive market, bidding wars push prices above market value. If three buyers bid up the price to $400,000, but the most recent comp sales support $385,000, the appraiser will mark it down. You paid for the privilege of winning the auction, not for true market value.
The market shifted. You made your offer in March; the appraisal occurs in April. If similar homes listed in that interval sold for 3% less, the appraiser's comps are fresher and lower than when you negotiated.
The appraiser chose different comps. If your property is on the border of two neighborhoods, the appraiser might emphasize comps from the less-desirable area. Likewise, if recent comps are mostly distressed sales or sales involving family members (non-arms-length), the appraiser might weight them differently.
The property has deferred maintenance or condition issues. If the inspection revealed a failing roof or failed septic system, the appraiser might reduce value further than the market price reflects.
The property is unique. A home with very few comparable sales—a luxury property, an unusual lot, or a rural property—is harder to appraise. The appraiser may make larger adjustments or be more conservative in valuation.
Gaps of 2–5% are normal in transitional markets or when you've beaten out multiple offers. Gaps above 5% signal trouble: either you overoffered, or the property has a legitimate valuation problem the seller wasn't transparent about.
Financing and the appraisal gap: the numbers
Here's where the gap becomes real. You offered $400,000 with 20% down ($80,000) and 80% financing ($320,000). The appraisal comes in at $385,000.
Your lender will finance only 80% of the appraised value: $385,000 × 0.80 = $308,000. You now have a shortfall: you promised to bring $80,000 down, but the lender will only provide $308,000. You must bring $80,000 + ($400,000 − $308,000) = $92,000 to the closing table. That's an extra $12,000 out of pocket, or 1.5% of your offer price.
If you only have $80,000 saved, you can't close without renegotiating the purchase price.
Options when you face an appraisal gap
Option 1: Bring extra cash. If you have the reserves and believe the property is truly worth the original price, you can make up the gap in cash. This is reasonable if the appraisal is just slightly low (under 2%) and you have 3–6 months of emergency expenses set aside. It's not reasonable if it depletes your savings and leaves you house-poor.
Option 2: Renegotiate the price. You contact the seller and propose a new price. "The appraisal came in at $385,000. Can we meet at $392,500?" Many sellers will negotiate at this point; they'd rather close at a slightly lower price than have the deal die. Some, especially in strong markets, will refuse. If they do, you're left with option 1 or option 3.
Option 3: Request a reappraisal. If you believe the appraisal is genuinely wrong, you can request the lender order a new appraisal. You usually pay for it ($400–$600), and there's no guarantee the second appraisal will be higher. This is a gamble and a time cost; reappraisals add 7–14 days to closing.
Option 4: Walk away. If the gap is large, the seller won't negotiate, and you don't have the cash, you can invoke your appraisal contingency and cancel the deal, recovering your earnest money. This is clean but means losing months of time and effort.
The appraisal contingency: your protection
The appraisal contingency in your contract states that the deal is conditional on the property appraising at or above your purchase price (or at least within a small range, like within 1%). If it doesn't, you can cancel without penalty.
However, appraisal contingencies are often waived in seller's markets. Sellers demand non-contingent offers to reduce closing risk. If you waive the appraisal contingency, you're responsible for any gap, regardless of size. This is a high-risk move unless you have substantial liquid reserves and strong conviction that the property is worth the premium.
A middle ground is a partial waiver: "I'll cover up to $10,000 of any appraisal gap, but not more." This gives the seller some certainty while protecting you from a catastrophic gap.
Real-world appraisal-gap examples
In 2022, homes in many US markets experienced 3–7% appraisal gaps as demand softened. A buyer who offered $500,000 for a house in March might face a $385,000 appraisal in May. The gap was real and widespread.
In 2024, as the market stabilized, appraisal gaps became rare. Offers were more in line with recent comps, and appraisals came in close to offer prices.
The takeaway: appraisal gaps are a product of market momentum and offer competitiveness, not (usually) a signal of a bad property. But they're real costs that must be planned for.
