What Is a Home Appraisal and Why Do Lenders Require It?

A home appraisal is an independent, licensed professional's opinion of a property's market value at a specific point in time. Lenders require appraisals on virtually every mortgage transaction because they will not lend more than a home is worth — the property is the collateral securing the loan. If a buyer defaults, the lender needs confidence that it can recover its investment by selling the home. An inflated purchase price that a lender funds without verification creates unacceptable risk for the institution.

The appraiser is hired and paid by the buyer (cost typically bundled into closing costs or paid at time of service), but the appraiser's client is legally the lender. This matters because the buyer is paying for an appraisal that is ultimately prepared for someone else's benefit. The buyer does, however, receive a copy of the appraisal report, which provides valuable insight into how the lender is thinking about the property's value.

In Florida, home appraisals are conducted by state-licensed or state-certified appraisers. The appraisal is ordered through an Appraisal Management Company (AMC) in most cases — a regulatory requirement implemented after the 2008 financial crisis to prevent lenders from directly influencing appraisers. This independence is intentional: the appraiser's job is to provide an objective, arms-length valuation, not to make the deal work.

For buyers in Tampa Bay, understanding the appraisal process upfront prevents a lot of anxiety mid-transaction. Appraisals are not rubber stamps. An appraiser who finds insufficient comparable sales to support the contract price will issue a value below contract price — and when that happens, the buyer, seller, and agents must decide how to proceed.

How Appraisers Determine Value

Residential appraisers primarily use the sales comparison approach, selecting three to six recently closed sales of similar properties and adjusting for differences between each comparable and the subject property. Adjustments are made for square footage, bedroom and bathroom count, lot size, age and condition, garage spaces, pool, location within the neighborhood, and upgrades. The appraiser reconciles the adjusted values of the comparables to arrive at an opinion of value for the subject property.

In Tampa Bay, appraisers draw comps from within a half-mile to one-mile radius when possible, but in rural or transitional areas they may need to expand their search. Recent sales carry the most weight — closed sales from the last 90 days are ideal; sales older than six months may require the appraiser to note market conditions adjustments to account for price trends. In a rapidly appreciating market (as Tampa Bay experienced from 2020–2023), this time-lag in comps sometimes caused appraisals to trail actual market values.

Beyond the comparable approach, appraisers evaluate the subject property's physical condition, noting deferred maintenance, safety issues, and any items that could affect marketability. For FHA and VA loans specifically, appraisers must flag any conditions that affect the health or safety of occupants — a requirement that goes beyond what conventional loan appraisals mandate. Peeling paint, non-functional systems, or significant roof deterioration can trigger required repairs before an FHA loan can close.

What Happens if the Appraisal Comes In Low

A low appraisal — where the appraised value is below the contract purchase price — creates a gap that must be resolved before the loan can fund. The lender will only finance a percentage of the appraised value (not the contract price), so the buyer is suddenly short of the funds needed to close at the agreed price.

There are four common paths when an appraisal comes in low. First, the seller can reduce the purchase price to the appraised value, eliminating the gap. Second, the buyer can make up the difference out of pocket — this is called covering the "appraisal gap." Third, buyer and seller can meet somewhere in the middle, splitting the gap. Fourth, if the buyer has an appraisal contingency in the contract, the buyer can cancel the deal and recover their earnest money deposit.

Before accepting a low appraisal, buyers and their agents should review the report for errors — incorrect square footage, wrong comparable selection, missed upgrades, or factual mistakes. If errors are found, the lender can submit a "Reconsideration of Value" (ROV) request to the appraiser with supporting documentation. The appraiser is not obligated to change the value, but if the ROV includes legitimate closed comparables the appraiser missed, the value may be revised upward.

In 2025, roughly 8–12% of Tampa Bay transactions encountered an appraisal gap situation. In those cases, the most common resolution was a combination of price reduction and partial buyer coverage, particularly in situations where both parties were motivated to close.

The Appraisal Contingency: How It Protects Buyers

An appraisal contingency gives the buyer the right to cancel the contract and recover their earnest money deposit if the property appraises below the purchase price by more than a specified amount. In the Florida AS-IS contract, the appraisal contingency is an optional addendum that buyers can include or exclude. Including it is generally in the buyer's best interest unless they have specific strategic reasons to waive it.

The contingency typically specifies a minimum appraised value — usually the purchase price — and a deadline by which the appraisal must be completed. If the appraisal comes in below the minimum value, the buyer has the right to cancel within a specified number of days of receiving the report. Without an appraisal contingency, a buyer who faces a low appraisal must either make up the gap out of pocket or lose their earnest money if they walk away.

Some buyers write appraisal contingencies with a "gap coverage" threshold — for example, agreeing to cover up to $10,000 in appraisal gap before the contingency triggers. This makes the offer more competitive than a full appraisal contingency (which sellers view as higher risk) while still protecting the buyer against catastrophic appraisal shortfalls.

Appraisal Waivers: What They Mean and When Sellers Want Them

An appraisal waiver means the buyer agrees not to use a low appraisal as a basis for canceling the contract or renegotiating price. In effect, the buyer is agreeing to pay the contract price regardless of what any appraisal says — either by covering the gap entirely or by using cash that does not require a lender-ordered appraisal at all.

Sellers in competitive markets strongly prefer offers with appraisal waivers because it eliminates one of the most common deal-killing scenarios. Appraisal waivers are most practical for buyers who are either paying cash, making a very large down payment (so the loan-to-value ratio still works even if the home appraises below contract), or who have deep reserves to cover any gap.

Fannie Mae and Freddie Mac also offer automated appraisal waivers on qualifying conventional loans — situations where their data models support the purchase price without requiring an in-person appraisal. These "property inspection waivers" or "value acceptance" offers are generated by the lender's automated underwriting system. When available, they can save the buyer $450–$650 in appraisal fees and eliminate appraisal-related delays.

Transaction Timeline: When Does the Appraisal Happen?

In a typical Tampa Bay transaction, the appraisal is ordered by the lender within 3–5 days of contract execution, after the buyer's initial disclosures are signed and the lender has received the purchase contract. The appraiser schedules an inspection of the interior and exterior of the property, usually within 5–7 days of being ordered. The written appraisal report is then delivered to the lender within 2–5 additional days, putting the typical total timeline at 10–21 days from contract to appraisal delivery.

This timeline intersects with the buyer's inspection period (typically 15 days in Florida). Buyers are often reviewing their inspection report and their appraisal simultaneously near the end of the inspection period. It is important to track both deadlines carefully because the appraisal contingency deadline may be different from the inspection period deadline — they run on separate tracks in the contract.

FHA vs. Conventional Appraisal Differences

FHA appraisals have requirements beyond the value assessment that conventional appraisals do not. FHA appraisers must evaluate the property's condition through an MPR (Minimum Property Requirements) lens, checking for safety, structural integrity, and sanitary conditions. Issues like peeling paint on a pre-1978 home (lead paint concern), a leaking roof, missing handrails on stairs, no working HVAC, or standing water in the crawl space must be noted — and the lender will typically require those conditions to be corrected before the loan can close.

Conventional appraisals focus primarily on value and do not require the same health-and-safety condition review. This makes conventional loans more flexible when buying a property that needs work. If you are purchasing a home that needs updates or has deferred maintenance, a conventional loan may be easier to close than an FHA loan.

FHA appraisals also carry a 120-day validity period — meaning the appraisal is good for 120 days from the effective date (with a possible 30-day extension). Conventional appraisals are generally valid for 12 months. If a deal falls through and the same buyer wants to repurchase the same property before the validity period expires, the original appraisal may be transferable, saving time and money.
