What is a home appraisal?
A home appraisal is an independent opinion of a property’s market value. In a mortgage transaction, the lender uses the appraisal to help confirm that the home is worth enough to support the loan being requested.
That matters because the home is collateral for the mortgage. If you are buying, refinancing, or borrowing against home equity, the lender needs a reasonable value estimate before final approval. The appraisal is not the same as a home inspection, and it is not a guarantee that the home is free of defects. It is mainly about value, condition, and market support.
For buyers in Buffalo, Western New York, Florida, and other markets, the same basic idea applies: the appraiser looks at the property and compares it with recent, similar sales to estimate fair market value.
When is an appraisal required?
An appraisal is common in several mortgage situations:
- Buying a home: The lender wants to confirm the purchase price is supported by the property value.
- Refinancing: The lender may need to verify your current home value before approving new loan terms. Learn more about refinancing options on our refinance page.
- Home equity borrowing: Your available equity depends partly on the home’s current appraised value. If you are comparing ways to access equity, start with our home equity overview.
- Certain loan programs: Conventional, FHA, VA, USDA, jumbo, and other mortgage programs each have their own appraisal rules.
In some conventional loan scenarios, a lender may receive an appraisal waiver or property data alternative through automated underwriting. That does not happen in every file, and it depends on factors such as the loan type, borrower profile, property data, and investor guidelines.
What does an appraiser look at?
The appraiser’s job is to estimate value using available market evidence. They generally consider:
- The property’s size, layout, age, and condition
- Lot size and location
- Recent comparable sales, often called “comps”
- Market trends in the surrounding area
- Improvements or updates, such as a renovated kitchen or newer roof
- Any visible condition issues that could affect value or safety
For a purchase, the appraiser usually reviews the sales contract too. That does not mean they simply match the contract price. The appraised value must be supported by the property and comparable sales.
For a refinance or home equity loan, the appraiser is not comparing the value to a purchase contract. Instead, they estimate the property’s market value based on the home and recent sales.
Appraisal vs. home inspection: why both matter
Borrowers often confuse an appraisal with a home inspection. They serve different purposes.
A home appraisal is ordered for the lender and focuses on value and general property condition. A home inspection is usually ordered by the buyer and focuses on the home’s systems, structure, and potential repair concerns.
An appraiser may note obvious problems, such as peeling paint, missing handrails, roof concerns, or safety issues. But the appraiser is not testing every outlet, inspecting the sewer line, or giving you a full repair roadmap. For buyer education, the CFPB offers helpful mortgage and homebuying resources through its tools for homebuyers.
How the appraisal affects your loan amount
The appraisal can affect your loan because lenders usually base the maximum loan amount on the lower of the purchase price or appraised value.
Here is a simple example:
- Purchase price: $300,000
- Appraised value: $290,000
- Lender value used for loan-to-value calculations: $290,000
If the appraisal comes in below the purchase price, the loan approval may need to be reworked. Depending on the contract and loan program, the buyer and seller may renegotiate, the buyer may bring more cash, or the deal may not move forward.
If the appraisal comes in at or above the purchase price, that part of the process is usually less of a hurdle, though the loan still needs to clear underwriting and other conditions.
What happens if the appraisal is lower than expected?
A low appraisal can be stressful, but it does not automatically end the transaction. Common options include:
1. Renegotiate the purchase price
The buyer may ask the seller to reduce the price to the appraised value or closer to it. Whether the seller agrees depends on the contract, market conditions, and the seller’s goals.
2. Bring additional cash
If the buyer wants to keep the same purchase price, they may need to cover the difference between the appraised value and the price. This is often called an appraisal gap. Not every borrower has the cash or wants to use it that way, so this should be reviewed carefully with the loan team.
3. Request a reconsideration of value
If there is a factual error or stronger comparable sale data, the lender may be able to submit a reconsideration of value. This is not a request to “raise the number” just because the parties want the deal to work. It needs to be supported by relevant information, such as missed comparable sales, incorrect square footage, or inaccurate property details.
4. Change loan structure or program
In some cases, adjusting the down payment, loan type, or other terms may help the file work. For example, conventional loan rules may differ from FHA or VA appraisal requirements. If you are comparing programs, see our guide to conventional loans, FHA loans, and VA loans.
FHA and VA appraisals can include property requirements
Government-backed loan programs may have property standards in addition to value requirements.
With an FHA loan, the appraiser may flag certain health, safety, or security issues that need to be addressed before closing. With a VA loan, the appraiser reviews the property under VA minimum property requirements. These requirements are not meant to replace a home inspection, but they can affect whether the property is eligible as-is.
Common issues that can cause conditions include missing handrails, broken windows, exposed wiring, peeling paint in certain situations, or major safety concerns. Requirements vary by program and property, so it is important to review appraisal conditions quickly if they come up.
HUD’s buying-a-home resources can also be useful for borrowers who want a broader understanding of the homebuying process and government-backed mortgage education.
How borrowers can prepare for an appraisal
You cannot control the appraiser’s opinion of value, but you can reduce avoidable issues.
For buyers:
- Review comparable sales with your real estate agent before making an offer.
- Understand whether your contract includes appraisal-related protections.
- Ask your loan officer how a lower value could affect your cash to close.
- Avoid assuming that a competitive offer price will automatically be supported by the appraisal.
For homeowners refinancing or applying for home equity financing:
- Make sure the appraiser can access the property, basement, garage, and any relevant areas.
- Provide a list of major updates, including dates and approximate scope.
- Tidy the home, but do not assume cosmetic cleaning changes market value.
- Be ready to discuss additions, finished space, or improvements that may not be obvious from public records.

What appraisers are not allowed to consider
Appraisals must follow fair housing and appraisal independence rules. Value should be based on the property, market data, and comparable sales — not on who is buying the home.
Appraisers also cannot be pressured by lenders, real estate agents, buyers, or sellers to hit a target value. Borrowers can provide accurate property information and point out potential errors through the proper process, but the final opinion of value belongs to the appraiser.

Why appraisals matter in changing markets
In a fast-moving market, appraisals can be challenging because closed sales may lag behind current buyer demand. In a slower market, appraisals may reflect recent price reductions or softer comparable sales. Either way, the appraiser is looking for supportable market evidence.
This is especially important in areas with varied housing stock. In Western New York, two homes on nearby streets can differ widely in age, updates, lot size, and condition. In Florida, condo rules, flood considerations, insurance costs, and community characteristics can also influence how borrowers think about affordability, even if those items are not all direct appraisal value drivers.
The appraisal is one piece of the mortgage approval puzzle. Credit, income, assets, property type, title, insurance, and loan program rules still matter too.
The bottom line
A home appraisal protects the lender’s collateral position, but it also gives borrowers a reality check on the property’s market support. The best approach is to understand how the appraisal fits into your loan, ask questions early, and have a plan in case the value comes in lower than the contract price or expected value.
