An appraisal gap happens when a home appraises for less than the purchase price. If you offered $450,000 but the appraisal comes in at $430,000, you have a $20,000 gap. The lender will only loan based on the appraised value, so you need to cover the difference, renegotiate the price, dispute the appraisal or walk away. In competitive markets, buyers often include appraisal gap coverage clauses agreeing to cover some or all of a potential gap.
Understanding Appraisal Gaps
What Creates an Appraisal Gap
Common causes:
- Competitive bidding drives price above market value
- Rapidly appreciating market (appraisals lag)
- Unique property with few comparables
- Condition issues reduce value
- Appraiser uses outdated or distant comparables
Why It Matters
Lender’s perspective:
- Lender loans based on the lower of purchase price or appraised value
- Don’t want to lend more than collateral is worth
- Gap means buyer must make up the difference
Example:
- Purchase price: $450,000
- Appraisal: $430,000
- Gap: $20,000
- Loan amount (at 90% LTV): $387,000 (based on $430,000)
- Your expected loan: $405,000 (based on $450,000)
- Extra cash needed: $18,000
Your Options When Appraisal Is Low
Option 1: Renegotiate the Price
Ask seller to reduce price:
- To appraised value
- To split the difference
- Some reduction
Best when:
- Seller is motivated
- Market is cooling
- You have appraisal contingency
- Seller’s alternatives are limited
How to approach:
- Share appraisal with seller
- Explain lending constraints
- Propose new price
- Be prepared to negotiate
Option 2: Cover the Gap
Pay the difference in cash:
- Increase your down payment
- Bridge the gap yourself
- Keep the deal together
Example:
- Gap: $20,000
- Your planned down payment: $45,000
- New down payment needed: $65,000
Best when:
- You have extra cash
- You believe in the property’s value
- Competitive market with few alternatives
- Property has unique value to you
Option 3: Split the Difference
Meet in the middle:
- Seller lowers price some
- You cover part of gap
- Both parties compromise
Example:
- Gap: $20,000
- Seller reduces: $10,000
- You cover: $10,000
Common negotiation outcome when both parties want the deal to work.
Option 4: Dispute the Appraisal
Challenge the appraisal if:
- Appraiser missed comparable sales
- Factual errors exist
- Condition was misrepresented
- Upgrades weren’t valued properly
Process:
- Request reconsideration of value from lender
- Provide additional comparables
- Document errors or omissions
- Appraiser reviews and may revise
Success rate: Low, but worth trying if you have valid points
Option 5: Get a Second Appraisal
Order another appraisal:
- Through a different lender
- Or request second opinion
Considerations:
- Costs $400-$600 more
- No guarantee of different result
- Takes additional time
- Some lenders don’t allow
Option 6: Walk Away
Use your appraisal contingency:
- Get earnest money back
- Cancel the contract
- Find another property
When to consider:
- Gap is too large
- Can’t afford extra cash
- Seller won’t negotiate
- You believe appraisal is accurate
Appraisal Gap Coverage Clauses
What They Are
In competitive markets, buyers offer to cover appraisal gaps in their purchase offer:
- Promise to pay up to $X if appraisal is low
- Makes offer more attractive to sellers
- Reduces seller’s risk
How They Work
Example clause: “Buyer will cover any appraisal gap up to $25,000.”
If appraisal is:
- $20,000 low: Buyer covers $20,000
- $30,000 low: Buyer covers $25,000, must negotiate $5,000
Types of Coverage
Full gap coverage: “Buyer will cover any appraisal gap.” (Risky—unlimited exposure)
Capped gap coverage: “Buyer will cover up to $25,000 of any appraisal gap.” (Limited, calculable risk)
Up to X% of purchase price: “Buyer will cover appraisal gap up to 5% of purchase price.”
Before Offering Gap Coverage
Consider:
- Do you have the cash available?
- How competitive is the market?
- What’s the property worth to you?
- What’s your maximum exposure?
Disputing an Appraisal
Valid Reasons to Dispute
| Issue | Example |
|---|---|
| Factual errors | Wrong square footage, room count |
| Missing comparables | Recent sales appraiser didn’t include |
| Condition misstatement | Upgrades not properly valued |
| Wrong comparable selection | Used distant or dissimilar homes |
| Market changes | Recent price increases not reflected |
The Dispute Process
Step 1: Review the appraisal carefully
- Look for errors
- Note missing information
- Identify better comparables
Step 2: Prepare your case
- Document specific issues
- Gather supporting evidence
- Get agent’s help with comparables
Step 3: Submit reconsideration request
- Through your lender
- Include supporting documentation
- Be specific about concerns
Step 4: Appraiser reviews
- May revise value
- May stand by original
- Usually takes 3-7 days
What Works in Disputes
Strongest arguments:
- Factual errors (square footage, room count)
- Very recent comparable sales
- Documented condition/upgrade issues
Weak arguments:
- “I think it’s worth more”
- Emotional appeals
- Questioning appraiser’s judgment without evidence
Preventing Appraisal Gaps
Before Making an Offer
Research thoroughly:
- Study recent comparables yourself
- Understand market conditions
- Know how much above asking homes sell for
- Set a maximum true value in your mind
Consider offering limits:
- Offer what you can afford if gap occurs
- Don’t offer $50,000 over if you can’t cover gap
- Build gap coverage into offer price calculations
During the Transaction
Prepare for appraisal:
- Provide list of upgrades to appraiser
- Have agent share recent comparables
- Ensure access is clear
- Property should show well
Strategic timing:
- Newer sales = better comparables
- Avoid gaps between contract and appraisal
Market Conditions and Appraisal Gaps
Seller’s Markets
More common:
- Bidding wars push prices up
- Appraisals lag market
- Gaps are frequent
- Buyers often cover gaps
Buyer’s Markets
Less common:
- Prices at or below value
- Appraisals usually support price
- Sellers more likely to reduce if gap occurs
Rapidly Appreciating Markets
Highest gap risk:
- Values increasing monthly
- Comparables are already “old”
- Recent sales don’t reflect current prices
- Gaps can be significant
Financing Considerations
LTV Impact
Low appraisal affects loan-to-value:
- Loan amount based on lower value
- You need more cash
- May affect PMI requirements
Example:
-
Offer: $400,000
-
Planned 10% down: $40,000
-
Loan: $360,000
-
Appraisal: $380,000
-
Loan at 90% of $380K: $342,000
-
Extra cash needed: $18,000 (to cover gap)
-
Plus original down payment based on price
Down Payment Recalculation
| Scenario | Purchase Price | Appraisal | Down Payment | Gap Coverage | Total Cash |
|---|---|---|---|---|---|
| No gap | $400,000 | $400,000 | $40,000 | $0 | $40,000 |
| With gap | $400,000 | $380,000 | $40,000 | $20,000 | $60,000 |
PMI Considerations
If appraisal is lower:
- Your LTV based on lower value
- May affect PMI rate or requirement
- More equity position initially

Frequently Asked Questions
What is an appraisal gap?
The difference between your purchase price and the appraised value when the appraisal is lower. If you offered $450,000 and appraisal is $430,000, you have a $20,000 gap.
Who pays for the appraisal gap?
Either the buyer (covers with additional cash), the seller (reduces price), or both (split the difference). The lender won’t cover the gap—they only loan based on appraised value.
Can I walk away if the appraisal is low?
Yes, if your contract includes an appraisal contingency. You’ll get your earnest money back. Without the contingency, walking away may mean losing your deposit.
Should I offer appraisal gap coverage?
In competitive markets, it makes your offer stronger. Only offer what you can actually pay and are comfortable risking. Unlimited gap coverage is dangerous.
Can the appraisal be challenged?
Yes. Request a reconsideration of value through your lender with evidence of errors or additional comparables. Success isn’t guaranteed, but valid disputes sometimes result in revised values.
How common are appraisal gaps?
Very common in hot seller’s markets with multiple offers. Less common in balanced or buyer’s markets. The more competitive the bidding, the higher the gap risk.
Does the seller have to lower the price?
No. The seller can refuse and you can walk away (if you have contingency). Motivated sellers often negotiate; sellers with multiple offers may not.
