An appraisal is an independent professional estimate of a property's market value, ordered by your lender before it finalizes your loan. A licensed appraiser inspects the home and compares it to recent sales nearby, then reports a value the lender uses to make sure it is not lending more than the property is worth.
How does an appraisal work?
After your offer is accepted and you apply for a mortgage, your lender orders an appraisal from a licensed, independent appraiser. The appraiser is not chosen by you or the seller, which keeps the valuation objective. The buyer usually pays for it, often as part of closing costs, and the report goes to the lender.
The appraiser visits the property, notes its size, condition, features, and any upgrades, then researches comparable homes that recently sold in the area, commonly called comps. By adjusting for differences between those comps and the subject home, the appraiser arrives at an estimated market value. That figure directly affects your loan-to-value ratio and how much the lender will actually finance.
What appraisers weigh
No two homes are identical, so appraisers factor in a range of details to reach a defensible number:
- Location, neighborhood, and school zone.
- Square footage, lot size, and layout.
- Age, condition, and quality of construction.
- Renovations, upgrades, and added features.
- Recent sale prices of comparable nearby homes.
- Current local market conditions and demand.
If the appraisal comes in at or above your agreed price, the loan generally moves forward smoothly. If it comes in low, the lender may only finance based on the lower value, which can create a gap you have to solve. That situation is common enough to have its own name, the appraisal gap.
Appraisal vs. home inspection
It is easy to lump these together because both involve someone examining the home, but they protect different interests. An appraisal is ordered by the lender to confirm value and protect the loan. A home inspection is arranged by the buyer to evaluate the property's physical condition and uncover defects.
The appraiser's walkthrough is relatively brief and value-focused; they are not testing whether the furnace runs well or the roof is near the end of its life in the way an inspector would. Conversely, an inspector does not tell you what the home is worth. The appraisal can change your financing; the inspection can change what repairs you negotiate or whether you proceed at all.
Because they serve distinct purposes, most transactions include both. Together they answer two separate questions every buyer should care about: is the price reasonable, and is the house in good shape.
Who relies on the appraisal, and why it matters
The appraisal matters most to the lender, since it protects the money they are lending, but it also protects you as the buyer from overpaying. If you are financing a home you have not seen in person, the appraisal adds an independent professional check on value, which is reassuring when you are buying across borders.
Pros | Cons |
|---|---|
Provides an independent, professional estimate of market value | Adds a fee the buyer typically pays, whether or not the deal closes |
Protects you from borrowing more than the home is worth | A low appraisal can stall or complicate financing |
Can strengthen your position if it comes in above the agreed price | Values are estimates and can vary between appraisers |
Required by most lenders, so it is a built-in safeguard | Fast-moving markets can make recent comps hard to pin down |
If an appraisal comes in lower than expected, you usually have options: renegotiate the price with the seller, cover the difference in cash, dispute the appraisal with supporting data, or, if you have the right contingency, walk away. Knowing these paths in advance keeps a low number from derailing your purchase.
Frequently asked questions
The buyer usually pays for the appraisal, often as part of closing costs or upfront during the loan process. The lender orders it, but the fee lands on you and is generally not refundable even if the deal falls through. Costs vary by market, property type, and complexity of the assignment.
A low appraisal means the lender may only finance based on the appraised value, leaving a gap. You can ask the seller to lower the price, pay the difference in cash, challenge the appraisal with additional comps, or use an appraisal contingency to exit. The right move depends on your contract and finances.
The on-site visit is often under an hour, but the full report can take several days to a week or more to reach the lender, depending on the appraiser's workload and market conditions. Timelines vary, so build some buffer into your closing schedule to avoid delays.
Sometimes. For certain loans and strong borrower profiles, lenders may offer an appraisal waiver, especially when automated valuation models give enough confidence. Waivers are not guaranteed and depend on the loan program, the property, and your down payment. Ask your lender whether you qualify and weigh the trade-offs before skipping it.
