You have lost three houses. Each time, the winning offer came in over asking, and your agent told you it included appraisal gap coverage. Nobody explained what that phrase actually commits a buyer to do.

This post walks through it. What an appraisal gap is, what happens if the appraisal comes in low, how much extra cash a shortfall actually costs depending on your down payment, and three ways to write the clause instead of just waiving your protection outright. I will also tell you where the local data is solid and where it is not, because your offer decision should not rest on a number I cannot back up.

What the market actually looks like right now

The most reliable local figures come from NYSAR data reported by the Rochester Business Journal. For Monroe County in May 2026, the median sale price hit $308,500, a new county record, up 7.9 percent from $286,000 in May 2025. The previous record was $300,000 in June 2025.

The interesting part is the volume. New listings were essentially flat year over year, 844 in May 2026 against 853 in May 2025, while closed sales fell 17.6 percent to 512. Prices are setting records on fewer transactions and no new supply. That is the condition that produces bidding wars.

Two more data points worth holding onto. Realtor.com data hosted on FRED puts the Monroe County median listing price at $319,900 in May 2026. Zillow's home value index for the county was $285,439, up 4.1 percent year over year, as of its April 30, 2026 update. Note that the Zillow number is an automated valuation index, not a record of what houses sold for, so do not stack it against the NYSAR median.

You may run into a much louder claim. One aggregator, Houzeo, reported that city of Rochester homes sold for 120.57 percent of asking price in July 2026. I am not going to build an argument on that. The same page reports 51 days on market, which does not happen in a market where the typical house clears 20 percent over list, and the same provider's statewide figure for New York is 100.54 percent of list. Homes selling over asking in Rochester is real. Twenty percent over asking as a median is not something I can stand behind.

What an appraisal gap actually is

Your lender does not lend against the price you agreed to pay. It lends against the appraised value, or the contract price, whichever is lower.

So a Monroe County home appraisal is not a formality that confirms your offer. It is an independent opinion of value, and when the seller has five offers pushing the price past every recent comparable sale, that opinion can land under your contract price. The difference between the two is the appraisal gap.

Here is the part that gets blurred. Waiving the appraisal contingency and agreeing to cover a gap are two separate acts. Waiving the contingency removes your right to renegotiate the price or walk away because of a low appraisal. The cash obligation comes after that, because the lender will still only lend against appraised value. Once you have given up the exit, the shortfall has to come from your pocket to close.

I have not found a credible local statistic on how often appraisals come in under contract in Monroe County, so I am not going to quote one. What I can tell you from being in these houses is that the risk concentrates in specific situations: a sale price well above the last comparable on the street, an unusual property with few true comps, and heavily renovated houses in neighborhoods where nothing similar has traded recently.

What happens if the appraisal comes in low

Say you go to contract at $325,000 and the appraisal comes back at $310,000. A $15,000 gap. What that costs you in cash depends on your loan-to-value.

• 20 percent down. You planned a $260,000 loan and $65,000 down. The lender will now cap the loan at 80 percent of $310,000, which is $248,000. To close at $325,000 you bring $77,000. That is $12,000 more than you budgeted.
• 5 percent down. You planned a $308,750 loan and $16,250 down. The lender caps at 95 percent of $310,000, or $294,500. You bring $30,500. That is $14,250 more than you budgeted.

The smaller your down payment, the closer the gap cost gets to the full shortfall. And that cash cannot be borrowed inside the mortgage. It has to be documented, sourced funds, on top of your closing costs and any reserves the lender requires. If a gap payment pushes you across an equity threshold, you may also pick up mortgage insurance you were not planning on.

If you kept your appraisal contingency, you have options instead: ask the seller to lower the price, split the difference, request a reconsideration of value with better comparables, or terminate and get your deposit back under the contract terms. If you waived it, none of those are rights. They are favors you have to ask for.

Appraisal gap coverage explained: three ways to write it

The capped version is the one most buyers should be using. It tells the seller you will not run at the first sign of a soft appraisal, and it tells you, before you sign, the largest check you could be asked to write. Pick a cap you can actually pay without touching the money you need for a roof or a furnace.

Scaling the math for Pittsford, Mendon and the rest of the south county

Every price figure I can source is either the city of Rochester or all of Monroe County. There is no verified median I can publish for Pittsford, Brighton, Mendon, Honeoye Falls, Henrietta, West Henrietta or Rush, and I am not going to make one up.

What matters is the arithmetic. Gap exposure scales with price. A 5 percent shortfall on the county median of $308,500 from May 2026 is about $15,425. On a house priced well above that median, which describes a lot of what trades in Pittsford and Mendon, the same 5 percent is a materially larger number. Any gap cap you agree to should be calculated on the actual price of the actual house, not on a countywide average.

Where New York's attorney approval period fits

New York transactions run through an attorney approval period, which affects how and when a buyer can exit a deal. That timing interacts with your appraisal terms, and the customs are not identical across the state. I am not going to characterize your legal rights here. Ask your real estate attorney to walk you through exactly what your contract says about appraisal, attorney approval, and deposit return before you sign anything with gap language in it. That conversation costs you nothing and it is the one that protects you.

A buyer offer strategy that does not start with a blank check

Gap coverage is one lever. It is not the only one, and it is rarely the cheapest one.

• Get the comps before you write. If recent sales support your number, the appraisal risk is small and a modest cap costs you little. If your offer would set a new high for the street, that is the deal where a waiver bites.
• Tighten the inspection instead of the appraisal. A shorter inspection window or a defined repair threshold can be worth more to a seller than gap language, and it does not obligate you to find cash at closing.
• Use timing. Closed sales fell 17.6 percent year over year in May 2026 per NYSAR. Sellers who need a specific closing date will trade on it.
• Know your true cash ceiling. Down payment, closing costs, reserves, gap cap, and a real repair fund. Whatever remains after those is your cap, and not a dollar more.
• Be willing to lose one. In a market with 0.33 months of supply, the temptation is to win at any structure. Overpaying with cash you cannot replace is a worse outcome than a fourth lost bid. For reference, a market is generally considered balanced somewhere between five and six months of supply.

If you are mid search in Henrietta, Pittsford, Brighton, Mendon, Rush or Honeoye Falls and you want a second read on what your last three offers were actually competing against, send them to me. I will pull the comparable sales on the next house you like, tell you honestly whether it will appraise at what you would need to pay, and put a number on your gap cap before you sign rather than after.

Schedule a time with Khem Kadariya and bring your budget and your losing offers. We will work the math together.

About this data

The figures in this post were compiled from publicly available sources including Houzeo, Movoto, Zillow, Redfin and FRED (Federal Reserve Bank of St. Louis), along with other public market data. Real estate numbers change quickly, and these were accurate as of August 2026. For current figures on a specific home, street, or town, ask me directly rather than relying on a published average.
