Home Appraisal Guide

Your lender requires an independent appraisal before funding your loan. Here's how the process works, what appraisers actually look at, and what your options are if the appraisal comes in below your purchase price.

What an Appraisal Is (and Isn't)

An is an independent, professional estimate of a home's market value, ordered by your lender before they finalize your loan. It protects the lender from loaning more than the collateral — the home — is worth. As a side effect, it also protects you from significantly overpaying relative to what the market supports.

Appraisal vs. inspection — not the same thing

The inspection evaluates the home's condition — what's broken, worn, or unsafe. The appraisal evaluates the home's market value — what it's worth compared to similar homes that have sold recently. They're separate processes, performed by different professionals, usually at different times.

You're typically responsible for the fee as part of or upfront, usually $400–$800 depending on the property size and location. The report belongs to you — you're entitled to a copy and should request one as soon as it's available.


How the Appraisal Process Works

The is ordered by your lender — typically within a few days of your being accepted — and follows a standardized process:

1. Ordering

Your lender orders the appraisal, typically through a neutral Appraisal Management Company (AMC) to ensure independence from the transaction.

2. Site visit

A licensed appraiser visits the home to measure square footage, photograph the interior and exterior, and assess the overall condition and features.

3. Comparable research

The appraiser researches recent sales of similar homes (comparables, or "comps") nearby — usually within the past six months and within a close radius.

4. Report delivery

A detailed report is delivered to your lender, including the appraised value, a grid of comps, photos, and notes on condition or value-affecting factors.

5. Underwriting review

Your lender's underwriting team reviews the appraisal to confirm the property supports the loan amount before issuing final approval.

Timeline

The full appraisal process — from ordering to underwriting review — typically takes 1–3 weeks. Your agent or lender can give you a realistic estimate based on current appraiser availability in your area.


What Appraisers Actually Evaluate

Unlike a — which is highly subjective and depends on the individual inspector — an follows strict, standardized guidelines set by lenders and government-sponsored entities like Fannie Mae and Freddie Mac. Appraisers are looking at the same categories on every report.

Physical characteristics

Square footage, lot size, number of bedrooms and bathrooms, garage, and overall layout.

Condition and age

Overall quality of construction, age of major systems, and evidence of deferred maintenance or recent renovation.

Comparable sales

Recent nearby sales of similar homes — typically within six months and close in size, age, and features — are the primary driver of appraised value.

Upgrades and features

Recent kitchen remodels, new HVAC, updated bathrooms, or other notable improvements can add value — but only if comparables support it.

Location factors

School district, proximity to busy roads, views, noise sources, and neighborhood trends all affect value in either direction.

Market conditions

Whether the local market is rising or declining affects how aggressively the appraiser weights recent comps.

What appraisers don't factor in

Personal value to you, emotional attachment, or what you paid for the home are irrelevant to the appraisal. The appraisal reflects what the market would pay — not what the home is worth to you specifically.


Understanding Your Appraisal Report

Once delivered, your report will typically be 10–30 pages. Ask your lender for a copy as soon as it's available — you're entitled to review it, and doing so early gives you time to act if there's a problem.

Appraised value

The single number that determines whether your loan can proceed as structured. If this is equal to or greater than your purchase price, you're clear to close.

Subject property summary

The appraiser's description and measurements of the home, including condition ratings and notes on any deficiencies observed during the site visit.

Comparable sales grid

A side-by-side comparison of the subject property against 3 or more recent nearby sales. The appraiser makes dollar adjustments for differences in size, condition, features, and location.

Photos

Interior and exterior photos taken during the site visit, plus a street view. These document what the appraiser actually observed.

Condition notes

Flagged issues that affect value or require attention — repairs the lender may require before funding the loan (called "lender-required repairs").


When the Appraisal Comes in Low

A low — when the comes in below your agreed purchase price — is one of the most stressful moments in a transaction. But it's not an automatic deal-killer. You generally have five paths forward.

Renegotiate the price

Ask the seller to lower the purchase price to match the appraised value. In a buyer's market or with a motivated seller, this is often the cleanest resolution.

Cover the appraisal gap

Pay the difference between the appraised value and your purchase price in cash, on top of your down payment. This keeps the deal alive but increases your out-of-pocket costs.

Split the difference

Many buyers and sellers meet in the middle — you cover part of the gap in cash and the seller lowers the price for the rest. This is the most common outcome.

Challenge the appraisal

Request a reconsideration of value from your lender if you have evidence of errors (wrong square footage, missed comps) or can provide better comparable sales the appraiser didn't consider.

Walk away

If you have an active appraisal contingency and can't reach an agreement, you can terminate the contract and recover your earnest money.

About appraisal gap clauses

In competitive markets, some buyers include an appraisal gap clause in their offer — committing in advance to cover a shortfall up to a specified amount. This can strengthen your offer, but only agree to a gap amount you can actually afford to cover. Run the numbers with the Mortgage Calculator before committing.


Tips to Support a Fair Valuation

You typically can't contact the appraiser directly during the process — lender regulations require independence. But there are still meaningful things you can do before and after the site visit.

Give your agent's comps to the lender

If your agent has identified recent comparable sales that support the purchase price, share them with your lender — who can pass them to the appraiser through proper channels.

Prepare a list of improvements

Document any significant upgrades (roof replacement, HVAC, kitchen remodel) with approximate dates and costs. The appraiser may not know about work done in recent years.

Make sure the home looks its best

The appraiser forms a condition impression during the site visit. A clean, decluttered, well-lit home signals that it has been maintained — which can affect condition ratings.

Act quickly if you want to challenge

Reconsideration of value requests have deadlines — typically a few days after report delivery. If you believe the appraisal contains factual errors or overlooked relevant comps, raise it with your lender immediately.


What Should You Do Next?

Once the appraisal clears and underwriting gives final approval, you're approaching the finish line. Closing day is the last major step — when documents are signed, funds are transferred, and keys change hands.
