The purpose of the lender’s appraisal is to give the bank an independent estimate of what your property is worth, so it knows the home can cover the loan if you stop paying. That single number does a lot of work: it protects the lender’s collateral, sets the ceiling on how much you can borrow, drives whether you’ll pay mortgage insurance, and flags condition problems that could hurt resale. For you as the borrower, it also acts as a check against overpaying with borrowed money.
Why Lenders Require an Appraisal
A mortgage is a bet on two things: your ability to repay, and the property’s ability to cover the debt if you can’t. The appraisal addresses the second half. If you default, the lender’s realistic path to recovery is foreclosing and selling the home, and that sale has to generate enough to cover the remaining balance plus legal fees, holding costs, and the discount foreclosure properties tend to sell at.
To estimate what the property would actually sell for today, the appraiser studies recent sales of comparable homes nearby. These “comps” anchor the valuation in real transaction data. The appraiser adjusts for differences in square footage, lot size, condition, and features to reach a defensible number. The goal is a realistic recovery estimate, not a best-case one.
Your down payment adds a second layer of protection. A 20% down payment means the property could lose a fifth of its value before the lender’s principal is at risk. The appraisal confirms that cushion actually exists at the price you’ve agreed to pay.
How the Appraised Value Sets Your Loan Amount
The appraisal controls the maximum the lender will finance through the loan-to-value ratio, or LTV. Divide the loan amount by the property value and you have LTV. The catch: lenders use the lower of the purchase price or the appraised value in that formula.
Say you agree to buy a home for $400,000, but the appraisal comes back at $380,000. If the lender’s maximum LTV is 80%, it will lend up to $304,000, which is 80% of the appraised value. You’d need to cover $96,000 out of pocket, not the $80,000 you originally planned as a 20% down payment on the contract price.
Private Mortgage Insurance
When your down payment is less than 20%, LTV exceeds 80%, and the lender faces more risk. Conventional conforming loans require private mortgage insurance (PMI) to offset that risk. PMI protects the lender, but you pay for it. Fannie Mae’s coverage requirements scale with LTV: the higher your LTV, the more coverage the insurer must provide, and the higher your monthly premium.1Fannie Mae. Mortgage Insurance Coverage Requirements
PMI isn’t permanent. Under the Homeowners Protection Act, you can request cancellation once your loan balance is scheduled to reach 80% of the property’s original value, provided you have a good payment history. “Original value” is the lesser of the purchase price or the appraised value at closing. Even if you do nothing, the servicer must automatically terminate PMI when the balance is scheduled to hit 78% of original value.2Federal Reserve. Homeowners Protection Act of 1998 The appraisal sets the baseline that governs both thresholds for the life of the loan.
Government-Backed Loans
FHA loans allow LTV as high as 96.5%, meaning borrowers can put down as little as 3.5%. VA loans often finance 100% of the purchase price. With equity cushions that thin, the appraised value becomes the hard ceiling the lender uses to enforce program LTV limits. There’s no negotiating around it.
Property Condition and Marketability
The appraisal isn’t only about the dollar figure. The appraiser also evaluates the home’s physical condition, because a property in poor shape is harder to sell quickly and usually fetches less. The lender needs collateral it can actually liquidate at a reasonable price.
The appraiser notes readily observable problems that could affect structural integrity, safety, or insurability. Foundation cracks, severe water damage, faulty electrical systems, and environmental hazards all make the report. For government-backed loans like FHA and VA, the property must meet minimum property requirements covering health, safety, and structural soundness. The federal agencies guaranteeing those loans don’t want to insure a home that would be difficult to resell.
If the appraiser flags necessary repairs, the lender may condition your approval on completing them before closing. Peeling paint on a pre-1978 home is a common one under FHA guidelines, because of lead-paint concerns. A property that needs significant work sells at a steep discount or sits on the market for months, both of which erode the lender’s recovery position.
Who Pays and What It Costs
You pay for the appraisal, even though the lender orders it and is the primary beneficiary. The fee shows up on your closing cost estimate, though many lenders collect it upfront since the appraisal happens well before closing. Standard single-family appraisals for conventional loans generally run $300 to $400. FHA, VA, and USDA appraisals cost more because the appraiser evaluates additional property-condition requirements; expect $400 to $900 depending on complexity and location.
Larger properties, unusual construction, rural locations, and multi-unit buildings push costs higher. If the lender orders a second appraisal, sometimes required for jumbo loans or volatile markets, you typically pay for that one too.
Why You Don’t Deal with the Appraiser Directly
Federal law makes it illegal for anyone with a financial interest in the transaction to pressure, bribe, or threaten an appraiser into hitting a target value. That includes lenders, loan officers, real estate agents, and borrowers. You can’t withhold payment because you didn’t like the number, imply that future work depends on favorable valuations, or tie compensation to whether the loan closes.3Office of the Law Revision Counsel. United States Code Title 15 – 1639e Appraisal Independence Requirements
That’s why most lenders order appraisals through appraisal management companies, or AMCs, which sit between loan production and the appraiser. The separation is deliberate. It prevents the loan officer earning a commission on your closing from hand-picking an appraiser likely to deliver a friendly number.
The law does allow some contact. Anyone can ask the appraiser to consider additional comparable sales, provide more detail on the value conclusion, or correct factual errors.3Office of the Law Revision Counsel. United States Code Title 15 – 1639e Appraisal Independence Requirements Those requests are how the reconsideration of value process works.
Your Right to a Copy of the Report
You’re entitled to a free copy of the appraisal. Under Regulation B, the lender must provide you with a copy of every appraisal and written valuation developed for your loan application, and must deliver it promptly after completion or at least three business days before closing, whichever comes first.4Consumer Financial Protection Bureau. Regulation B 1002.14 Rules on Providing Appraisals and Other Valuations
The lender must also notify you of this right in writing within three business days of receiving your application. Even if the loan falls through, the lender still owes you the appraisal copy within 30 days of deciding the transaction won’t happen.4Consumer Financial Protection Bureau. Regulation B 1002.14 Rules on Providing Appraisals and Other Valuations Review it carefully. The information inside is your starting point if you need to challenge the value.
What Happens When the Appraisal Comes in Low
When the appraised value lands below the contract price, you have an appraisal gap. The lender will only finance based on the appraised value, not the price you agreed to pay. You have four practical options.
- Cover the gap in cash. If the purchase price is $500,000 and the appraisal is $480,000, you bring the extra $20,000 to closing on top of your planned down payment. The contract price stays the same, and the lender’s LTV math works because its loan is based on the appraised value.
- Renegotiate the price. Ask the seller to lower the price to match the appraisal, or meet somewhere in the middle. A seller who needs to close may accept rather than start over with a new buyer who will face the same appraisal.
- Walk away. If your purchase agreement includes an appraisal contingency, you can terminate the contract and get your earnest money deposit back when the appraisal falls short of a specified threshold. Without that contingency, you may forfeit the deposit.
- Request a reconsideration of value. If you believe the report contains errors or missed better comparable sales, you can challenge it.
A reconsideration of value (ROV) is a formal request from the lender to the appraiser asking them to revisit the report based on deficiencies or new information. Federal banking regulators issued interagency guidance in 2024 directing financial institutions to establish clear ROV policies and make it easier for borrowers to raise concerns.5Federal Register. Interagency Guidance on Reconsiderations of Value of Residential Real Estate Valuations
You can’t request an ROV just because you’re disappointed in the number. Legitimate grounds include factual errors (wrong square footage, incorrect lot size, missing features like a garage or renovated kitchen), better comparable sales the appraiser overlooked, and evidence that protected characteristics like race or neighborhood demographics may have improperly influenced the value. Contact your loan officer to start the process; the lender submits the request, not you. An independent review team evaluates the evidence, and if the concerns hold up, the appraiser may revise the value or the lender may order a new appraisal. Vague objections go nowhere. Raise concerns as soon as you receive your copy, while underwriting is still active.
When an Appraisal Isn’t Required
Not every mortgage needs a traditional appraisal. Fannie Mae offers “value acceptance” for certain transactions where its automated underwriting system has enough data to estimate value with confidence. Eligible transactions include purchases, refinances, and second homes involving one-unit properties, including condos, where the system issues an approval.6Fannie Mae. Value Acceptance
The program isn’t available for properties valued at $1 million or more, multi-unit buildings, manufactured homes, co-ops, new construction, or manually underwritten loans. A separate “value acceptance plus property data” option skips the full appraisal but still requires someone to collect interior and exterior property data before closing.7Fannie Mae. Value Acceptance Plus Property Data
An appraisal waiver saves you the fee and can speed up closing by a week or more. The trade-off is you lose an independent check on the property’s value and condition. If you’re buying in an unfamiliar market or the price feels aggressive, ordering a full appraisal even when one isn’t required can be worth the few hundred dollars.
