Overview
An appraisal gap is the difference between a property's contract price and its appraised value, calculated as Contract Price minus Appraised Price. Gaps show up most often when a buyer offers above recent comparable sales, which can happen in a hot seller's market but also shows up in Miami condos simply because appraisers rely heavily on recent sales within the same building, and older buildings with thin recent sales volume can appraise well below the agreed price. If the appraisal comes in low, buyers generally have three options: renegotiate, cover the difference in cash, or walk away, while sellers may need to adjust price expectations or wait for a cash buyer.
What Is an Appraisal?
An appraisal is a professional valuation of a property, conducted by a licensed appraiser who considers the property's size, condition, location, and recent sales of comparable properties. Lenders require an appraisal as part of the mortgage process to determine how much they're willing to lend against the property, though appraisals also get used for purposes like divorce or estate planning.
What Is an Appraisal Gap?
An appraisal gap is the difference between a property's contract price and its appraised value:
Contract Price − Appraised Price = Appraisal Gap
For example, if a condo is under contract for $800,000 but appraises at $750,000, the appraisal gap is $50,000. If the buyer's financing depends on the appraised value, they may not be able to borrow enough to cover the full contract price and would need to make up the difference out of pocket. If the seller was counting on the full contract price, they may need to adjust their expectations.
How the Appraisal Gap Affects Buyers
A large appraisal gap can cause a buyer to reconsider the deal altogether. If the appraised value comes in below the contract price, the buyer may need to bring additional cash to closing to cover the shortfall, since lenders typically won't finance above the appraised value. That extra cash requirement can strain a buyer's finances and sometimes leads them to walk away.
How the Appraisal Gap Affects Sellers
A low appraisal can affect a sale directly, and can also affect future buyers in the same building, since the low appraisal becomes part of the comparable sales data appraisers pull from going forward. If the gap is significant, sellers sometimes need to lower their asking price to keep the deal together or to attract the next buyer. This can be especially difficult for sellers who need to sell quickly and don't have time to wait for the market to catch up.
What Can Be Done to Close the Gap
For buyers, the first step is usually to renegotiate the price with the seller. Whether that works depends heavily on market conditions and how motivated the seller is. If renegotiation doesn't close the gap, buyers can choose to cover the difference in cash, or walk away from the deal if the contract includes an appraisal contingency.
For sellers, pricing competitively from the start is the best way to avoid an appraisal gap altogether. If a gap does show up, adjusting the price to match the appraisal, or waiting for a cash buyer who isn't relying on financing, are the two most common paths forward.
Why Appraisal Gaps Show Up Often in Miami Condos
Condo appraisals rely heavily on recent comparable sales within the same building, and in buildings with limited recent sales activity, appraisers sometimes have to reach back six to twelve months or more for comparables, which may not reflect current pricing at all. That's part of why cash offers remain common in Miami condo transactions: a cash buyer isn't exposed to the appraisal gap risk the way a financed buyer is.
Some buyers who make an offer not contingent on financing still choose to get their own appraisal done during the inspection period, specifically to understand their exposure before they're locked into the deal. In one case, a building with very few recent sales produced an appraisal nearly $600,000 below the contract price, because the appraiser had to rely on sales from many months prior that no longer reflected the unit's true value. Knowing that during the inspection period let the buyer walk away and recover their deposit rather than closing at a price the appraisal couldn't support.
Common questions
Most commonly, an offer price above recent comparable sales, whether due to competitive bidding or simply a thin pool of recent comparable sales in the same building.
Unless the buyer has an appraisal gap clause or is paying cash, the buyer typically needs to cover the shortfall out of pocket, since lenders generally won't finance above the appraised value.
If your contract includes an appraisal contingency, yes; you can typically renegotiate, cover the gap, or walk away and recover your deposit, depending on how the contingency is written.
Condo appraisals lean heavily on recent sales in the same building. Buildings with limited recent transaction volume can force appraisers to use older comparables that don't reflect the unit's current market value.
