What Is a Home Appraisal? Who Does It and What It Checks
What is a home appraisal? It is an independent estimate of a property's market value, prepared by a state-licensed or certified appraiser. The lender that is financing your purchase or refinance usually orders it. The lender wants proof that the home is worth at least as much as the money it is about to lend.
The appraiser walks the property, compares it with similar homes that sold nearby, and delivers a report that ends in one number. That number can change your loan amount, your down payment, or your refinance rate. This article explains why appraisals matter, how they work from order to report, what appraisers check, how to prepare, and what to do if the value comes in low.
We are a home inspection company on the Alabama Gulf Coast, and we see appraisals and inspections land in the same transactions all the time. Buyers and sellers often mix the two up, so we also cover how an appraisal and an inspection differ and when you need each.
Why a home appraisal matters in every transaction
Why lenders require an appraisal
Lenders require an appraisal because the home is the collateral for the loan. If a borrower stops paying, the lender has to be able to sell the property and recover what it lent. An appraisal gives the lender a documented, independent opinion of value so it does not lend more than the home is worth. The Consumer Financial Protection Bureau describes an appraisal as a written document that gives an opinion of how much a property is worth.
The value also shapes your terms. The FDIC notes that lenders use the appraisal to help determine your interest rate, required down payment, and whether you are approved. You usually pay the fee, even though the lender orders the report.
A lender will only finance what the appraisal supports, no matter what price you and the seller agreed on.
What the value means for buyers, sellers, and refinancers
The same number plays a different role depending on which side of the deal you are on.
Your situation | What the appraisal does | What can go wrong |
|---|---|---|
Buyer | Confirms you are not overpaying and sets the most the lender will fund | A low value forces more cash, a lower price, or an exit |
Seller | Tests your agreed price against recent nearby sales | A value below the contract price can stall or reopen negotiation |
Refinancer | Sets your loan-to-value (LTV) ratio | A lower value raises your LTV and can mean a higher rate or no deal |
Refinancing shows the effect clearly. Say you owe $240,000 and the home appraises at $320,000. Your loan-to-value ratio is 75% ($240,000 divided by $320,000). Lenders treat lower ratios as less risky, so 75% can earn a better rate than the same loan at 90%. If the home appraised at only $280,000, your ratio would climb to about 86%.
How a home appraisal works from order to report
Who performs the appraisal
Appraisers are state-licensed or certified professionals who value property for a living. Lenders typically order through an appraisal management company, which assigns an appraiser. Rules adopted after the 2008 financial crisis aim to keep buyers, sellers, and lenders from pressuring the appraiser or choosing a favorite.
That independence is the point. An appraiser has no stake in whether the sale closes, so the opinion is not shaped by anyone's hopes for the price.
The steps, in order
Here is the usual sequence for a purchase loan:
The lender orders the appraisal, and the management company assigns an appraiser.
The appraiser schedules a visit, often within a couple of days.
The appraiser walks the interior and exterior, measures, takes photos, and notes the condition. A standard home takes roughly 30 minutes to an hour, and larger or unusual properties take longer.
The appraiser researches comparable sales, public records, and local market conditions away from the property.
The appraiser writes the report, which commonly takes about a week and can run up to three weeks.
The lender receives the report. Under the FDIC's summary of the rule, the lender must give you a copy as soon as reasonably possible and no later than three days before closing.
What it costs and who pays
Expect to pay roughly $350 to $450 for a standard single-family appraisal. Angi's national average is $357, with a typical range of $314 to $423, and other sources put the average near $400. Condos, multifamily buildings, large lots, unusual homes, and FHA or VA loans usually cost more.
The buyer or refinancing owner normally pays, often at closing or at the time of service. Pay a second fee if a second appraisal is needed.
Budget about $400 for the appraisal, and know that you pay it even if the value disappoints you.
What appraisers check and what drags a value down
What appraisers look at
An appraiser compares your home with recent sales, so everything checked is something that makes one house worth more or less than another.
Category | What the appraiser notes |
|---|---|
Size and layout | Square footage, bedrooms, bathrooms, and how the rooms flow |
Age and condition | Roof, foundation, flooring, visible damage, and overall upkeep |
Upgrades | Kitchens, baths, windows, energy-efficient materials, and other improvements |
Lot and location | Lot size, zoning, nearby amenities, and the neighborhood |
Comparable sales | Similar homes that sold nearby recently |
Market conditions | Whether prices are rising, flat, or falling locally |
The comparable sales carry the most weight. Appraisers look for at least three similar nearby homes that sold recently, then adjust each sale price for differences such as an extra bathroom or a newer roof. The "net adjustment" line in the report shows how far those adjustments moved the value.
What hurts an appraisal
Several things regularly pull a value down, and some surprise sellers:
Deferred maintenance: a worn roof, soft wood, or a cracked foundation that is visible during the walkthrough.
Thin comparables: waterfront, historic, custom, or rural homes often have few close matches, so the appraiser must reach further.
A fast-rising market: appraisals rely on past sales, so they can trail a contract price in a bidding war.
Wrong records: if public records list incorrect square footage or miss a bedroom, the starting data is off.
Unfinished or unpermitted work: lenders may not count space that is incomplete or not properly permitted.
Loan-specific rules:FHA property requirements and VA loan rules set minimums, so safety or condition problems can hold up the loan.
Most low values trace back to condition, thin comps, or bad data, and only the data problems are fixable after the fact.
How to prepare and respond to the appraised value
Before the appraiser arrives
Preparation will not change the market, but it controls what the appraiser sees. Use this checklist:
Sellers and refinancers:fix broken items and clear clutter, and make sure every area is reachable, including the attic, garage, and any crawl space.
Document your upgrades: list improvements with dates, costs, and permits, and hand the list to the appraiser.
Buyers: pull recent sales nearby, work with an agent who knows the area, and include a financing contingency if you are using a loan.
Everyone: answer questions, but do not follow the appraiser around or argue value during the visit.
How to read the report
Most appraisers use the Uniform Residential Appraisal Report format. Start on the first page and confirm that the address, square footage, bedroom count, and lot size are correct. Find the final opinion of value, then read back through the comparable sales grid to see how the appraiser got there. A factual error in the first pages is the easiest thing to get fixed.
What to do if the value comes in low
Take a concrete case. You agree to buy at $350,000 with a conventional loan and 10% down. You planned a $315,000 loan and a $35,000 down payment. The home appraises at $335,000, and the lender bases the loan on the lower figure. At 90%, the loan becomes $301,500. Without a price change, your down payment rises to $48,500, which is $13,500 more than planned.
You have four realistic paths:
Ask the seller to lower the price. At $335,000, your 10% down payment is $33,500.
Split the gap with the seller.
Cover the gap in cash.
Walk away, if your contract has a financing or appraisal contingency.
You can also challenge the value, but you cannot do it directly. Only the lender, as the appraiser's client, can request a reconsideration of value. The FDIC advises collecting facts: a plat map to correct lot size, measurements for square footage, photos and receipts for improvements, and sales of similar homes from the past 12 months. If you suspect bias, the HUD PAVE resource explains how to file a complaint.
You challenge an appraisal with documented facts, because an appraisal is an opinion built on comparable sales.
Home appraisal vs. home inspection: key differences
The differences at a glance
An appraisal answers "what is this home worth," and an inspection answers "what condition is this home in." They are separate services with different clients and different results.
Home appraisal | Home inspection | |
|---|---|---|
Question answered | What is the market value? | What is the condition? |
Who orders it | Usually the lender | Usually the buyer |
Who does it | Licensed or certified appraiser | Licensed home inspector |
Focus | Comparable sales, size, location, visible condition | Structure, roof, electrical, plumbing, HVAC, and other systems |
Result | An opinion of value | A report on defects and safety issues |
Typical visit | About 30 minutes to an hour | About 3 to 4 hours for a standard home |
An appraiser notes visible flaws, but is not testing systems or looking for hidden problems. That is the inspector's job. Our home inspection cost is typically $350 to $550, depending on the property, and we deliver most reports the same day.
Why you usually need both
An appraisal protects the lender's money, and an inspection protects yours. A home can appraise at full price and still have a failing roof, wiring problems, or moisture damage that the appraiser never tested. A house with serious defects can also appraise low, but you would not know why without an inspection.
Use them together. The inspection report gives you repair requests and negotiating leverage. The appraisal tells you whether the price holds up. If you want a licensed, InterNACHI-certified inspector for the condition side, Trinity Home Inspections works under Alabama license HI-4691.
The short version
A home appraisal is a licensed professional's opinion of what a property is worth, and lenders use it to decide how much they will lend. For you, it sets the loan size, the down payment, and sometimes the rate. Prepare the property, check the report for factual errors, and know your options before a low value surprises you.
Remember that the appraiser values the home and does not inspect it. If you are closing on a new build, a new home inspection covers the condition side before you sign.
