# Appraisal gap calculator: offering over list in a bidding war Source: https://nobullshitloans.com/tools/appraisal-gap/ By Tyler Rood, Loan Officer, NMLS ID # 2064776, Edge Home Finance, LLC (NMLS ID # 891464). Updated 2026-11-09. ## The short answer For multiple offers or a gotta-have-it house, where you'd offer over list and waive the appraisal contingency, size the loan once, for your worst-case appraisal, so your payment doesn't change and your total cash stays inside one budget. An insurance reserve in that budget covers the higher loan-to-value if the value comes in short. On the calculator's defaults ($575,000 offer, $500,000 worst case, $150,000 budget), the loan is $445,500 and the worst case uses about $149,668 of the budget. This isn't 2021, and right now this calculator isn't my lead play. But when bidding wars come back, or when you've found a gotta-have-it house with other offers on the table, the appraisal gap calculator answers the question that keeps buyers from offering over list: what happens to my cash and my payment if the house appraises low? ## When to use the appraisal gap calculator In my read, late 2026 isn't a seller's market. Most of my buyers are winning with seller credits and seller-paid buydowns, not by outbidding anyone; that's the [financing side of a strong offer](https://nobullshitloans.com/buy/making-an-offer/). This calculator is for the exception: multiple offers or a house you have to have, a conventional loan, and more than 5% down. I built this structure in the 2020 and 2021 bidding wars, and it's how I won offers that looked impossible. ## How the structure works 1. Set one total cash budget, down payment plus closing costs plus the insurance reserve, that you'll spend no matter what the appraisal says. 2. Size the loan once, for the lowest appraisal you'd accept and still close. 3. If it appraises at your offer, your loan-to-value is lower, you may not need the insurance at all, and the reserve stays with you. 4. If it appraises low, the loan amount doesn't change, so neither does the payment. The loan-to-value goes up, and the mortgage insurance that covers it comes out of the insurance reserve inside your budget, not on top of it. ## How to use the calculator - **Your offer price.** What you'd write the offer at. - **Total cash you'll spend, no matter what.** Down payment, closing costs and the insurance reserve, as one number. - **Worst-case appraisal.** The lowest value you'd accept and still close. Often that's the list price. - **Closing costs.** From your estimate. - **Credit score.** It prices the insurance. ## How to read your result The big number is the loan amount, sized for the worst case. It's the same whichever way the appraisal lands, so your payment is too. **Worked example: Offer $575,000, worst-case appraisal $500,000** - Down payment: $129,500 - plus Closing costs: $15,000 - plus Mortgage insurance if it appraises at $500,000: $5,168 - equals: Cash in the worst case: $149,668 Note: Appraises at $575,000: loan-to-value 77.5%, no insurance, cash $144,500. _Hypothetical example on a $445,500 loan. Not a quote or an approval._ Appraise at $500,000 and the loan-to-value is 89.1%. That's the gap being covered by insurance instead of your cash. If the calculator says "Does not fit," lower the offer, raise the budget or narrow the gap. The insurance cost comes from the published rate cards of two national mortgage insurers (the newer one effective February 2026), priced by credit score and loan-to-value, at base rates. A real quote can land on either side of that, which is why I price it on the actual file before your offer goes in. How mortgage insurance works in general is on my page about [PMI and mortgage insurance](https://nobullshitloans.com/buy/mortgage-insurance/). What changes it: - **A lower worst case.** At $475,000, the loan becomes $448,000, the loan-to-value 94.3%, and the insurance about $7,750. Keep the worst case at or under 95% loan-to-value. Past 97%, the calculator warns you conventional programs won't go there. - **A lower score.** At 700, the loan is $448,000 and the insurance about $7,840. - **A smaller budget.** At $130,000, the loan grows to $468,500, and you'd carry some insurance even at a full appraisal. **My take** This was my favorite play in 2020 and 2021, and the reason it worked was the budget. You decide the total before you offer and build it for the worst case up front, so a low appraisal costs a number you already agreed to, not an open-ended gap. If you can't build a budget that survives the worst case, don't waive the contingency. Waiving it carries real risk, including your deposit if you can't close, so talk it through with your agent before you offer. If the appraisal has already come in low on a normal contract, that's a different conversation, covered in [what to do after a low appraisal](https://nobullshitloans.com/buy/appraisal/). Agents facing multiple offers can see how I set this up in [financing strategies that win offers](https://nobullshitloans.com/agents/winning-offers/). ## Frequently asked questions ### What happens if the appraisal comes in lower than my offer? Normally the lender lends off the lower of the price or the appraised value, so the gap comes out of your pocket unless the price is renegotiated, and with an appraisal contingency you can renegotiate or walk. With this structure you planned for it. The loan stays put, the payment stays put, and the insurance reserve covers the higher loan-to-value. Below your worst case it breaks, so know that number before you offer. ### Does waiving the appraisal contingency mean there's no appraisal? Not by itself. The contingency is a term in your contract, which your agent writes; the appraisal belongs to the lender, which orders one unless its automated underwriting offers to skip it. Waiving the contingency generally means a low value no longer gives you a way out, so ask your agent exactly what your contract says. ### Can I use this with an FHA or VA loan? No. It's built on conventional mortgage insurance, so it's a conventional-loan structure. VA appraisals work differently, and on a VA purchase a short value usually means renegotiating the price; here's [how VA appraisals work](/veterans/va-appraisal/). ### Do I get the insurance money back if I refinance later? No. On the rate cards this calculator uses, that insurance is paid once at closing and isn't refundable. If the home appraises at your offer and the loan comes in under 80% of the value, you never buy it, and the reserve stays in your pocket. ### Is this the same as appraisal gap coverage? Not quite. Appraisal gap coverage is a promise in the offer to cover a shortfall up to a set amount in cash. This structure plans the whole budget around the worst case instead, so a low value changes your loan-to-value, not your cash or your payment. ## Sources - [Fannie Mae Selling Guide B4-1.4-10, value acceptance (appraisal waiver)](https://selling-guide.fanniemae.com/sel/b4-1.4-10/value-acceptance-appraisal-waiver) - [Fannie Mae Eligibility Matrix (DU), maximum loan-to-value ratios](https://singlefamily.fanniemae.com/media/20786/display) ## Disclosures Individual Originator: Tyler Rood, Loan Officer, NMLS ID # 2064776 (www.nmlsconsumeraccess.org).
