The Home Appraisal Process: What Buyers and Sellers Should Know

Buying or selling a home involves a lot of moving parts, and the appraisal is one step that often brings up questions.

What exactly does an appraiser look at? How is the value determined? How long does the process take? And what happens if the appraised value doesn’t match the purchase price?

Understanding the home appraisal process can make this part of the transaction feel much more straightforward.

What Is a Home Appraisal?

A home appraisal is a professional assessment of a property’s current market value completed by a licensed or certified real estate appraiser.

When a buyer is financing a home with a mortgage, the lender will typically order the appraisal to help determine whether the property provides enough value to support the loan.

An appraisal may also be required in other situations, including refinancing or certain types of home equity financing.

It’s important to understand that an appraisal is different from a home inspection.

A home inspection focuses primarily on the physical condition of the property and potential defects. An appraisal focuses on determining market value.

What Happens During the Appraisal?

The process typically includes a property visit followed by research and analysis.

During the visit, the appraiser may examine the interior and exterior of the home, take measurements, take photographs, and document features that could affect value.

The amount of time spent at the property can vary depending on the home’s size, condition, layout, and complexity.

A larger or more unique home may take longer to evaluate than a smaller, more straightforward property.

What Does an Appraiser Look At?

An appraiser considers a variety of factors when evaluating a home.

These may include the home’s overall condition, size, layout, number of bedrooms and bathrooms, finished living area, garage, foundation, roof, heating and cooling systems, and other permanent features.

The appraiser may also note visible signs of deferred maintenance or damage that could affect the home’s value or marketability.

Exterior features can also matter. The appraiser may consider the lot, driveway, garage, landscaping, exterior condition, decks, porches, pools, and other permanent improvements.

Location and neighborhood characteristics are also part of the valuation process.

The goal is not to judge whether the home is decorated well or matches a particular style. The appraiser is trying to understand how the property compares with other homes in the market.

Which Improvements Can Affect Appraised Value?

Not every improvement affects value the same way.

Permanent and functional improvements can play a larger role than purely cosmetic updates.

Examples may include an updated kitchen, renovated bathrooms, additional finished living space, a finished basement, or newer major systems.

Luxury finishes or cosmetic upgrades may help a home show better to buyers, but they don’t always increase appraised value by the same amount that was spent on them.

This is one reason homeowners should not assume that every dollar spent on renovations will translate directly into a higher appraisal.

How Comparable Sales Affect the Appraisal

After evaluating the property, the appraiser researches recent sales of similar homes, commonly called comparable sales or comps.

Comparable homes are typically selected based on factors such as location, size, age, condition, layout, and features.

Because no two homes are exactly alike, the appraiser analyzes the differences between the subject property and the comparable homes.

Recent sales are especially important because they help show what buyers have actually been willing to pay for similar properties in the current market.

How the Appraiser Determines Value

The appraiser looks at the property itself, the comparable sales, and the surrounding market together.

The home’s location, condition, improvements, size, features, and recent market activity all contribute to the final opinion of value.

This is why a home’s listing price, purchase price, owner estimate, or renovation cost does not automatically determine the appraised value.

The final value must be supported by the available market data.

What Is Included in the Appraisal Report?

After completing the property evaluation and market research, the appraiser prepares a written report.

The report may include information about the property, site, neighborhood, improvements, comparable sales, market conditions, and the appraiser’s final opinion of value.

When the appraisal is part of a mortgage transaction, the completed report is generally provided to the lender for review.

What Happens After the Appraisal?

Once the appraisal is completed, the lender reviews the appraised value as part of the mortgage underwriting process.

If the appraised value meets or exceeds the purchase price, the transaction can generally continue toward closing, assuming the buyer meets the lender’s other requirements.

If the appraisal comes in below the purchase price, the transaction may require additional steps.

Depending on the contract and circumstances, the buyer and seller may need to discuss the price, financing, or other possible options.

What Happens If the Appraisal Comes In Low?

A low appraisal means the appraiser’s opinion of value is below the agreed-upon purchase price.

This can create a financing issue because a lender generally bases its loan decision partly on the appraised value of the property.

What happens next depends on the purchase agreement, financing, appraisal contingency, and the parties involved.

Possible next steps may include reviewing the report, addressing potential errors, renegotiating the purchase price, increasing the buyer’s cash contribution, or exploring other contract options.

Buyers should discuss their specific situation with their real estate agent and lender before making a decision.

FHA Appraisals

The basic appraisal process is similar across many transactions, but certain loan programs have additional property requirements.

FHA appraisals include considerations related to the home’s condition, safety, and structural soundness.

Potential concerns may include deteriorating paint, roof or foundation problems, water damage, exposed electrical components, or other conditions that could affect safety or structural integrity.

If an issue is identified, repairs may sometimes be required before the loan can proceed.

VA Appraisals

Homes financed with a VA loan may also need to meet minimum property requirements.

These standards are designed to help ensure the property is safe, sanitary, and structurally sound.

The appraisal may consider factors such as heating, utilities, roof condition, foundation, and other health and safety concerns.

If the appraiser identifies an issue, the lender can explain what may need to be addressed before the transaction moves forward.

How Sellers Can Prepare for an Appraisal

Sellers typically don’t need to make dramatic changes before an appraisal, but it can help to make the property easy to access and evaluate.

Make sure rooms, garages, storage areas, and exterior spaces are accessible.

If significant improvements have been made to the property, having information available about those updates may also be useful.

Examples could include a new roof, HVAC replacement, kitchen renovation, bathroom remodel, addition, or other permanent improvements.

The appraiser will still make an independent determination of value, but accurate information about the property can help make the process smoother.

How Buyers Should Think About the Appraisal

For buyers, the appraisal is one part of the financing process.

It should not be confused with the home inspection, and it should not necessarily be viewed as a guarantee about the property’s future value.

The appraisal provides an independent opinion of the home’s current market value based on the property and available market data at that point in time.

Understanding that distinction can help buyers know what the appraisal is—and what it isn’t.

The Bottom Line

A home appraisal involves much more than a quick walk-through.

The appraiser evaluates the property’s characteristics and condition, researches comparable sales, reviews relevant market information, and uses that data to develop an opinion of the home’s current market value.

For buyers, the appraisal can play an important role in mortgage approval. For sellers, understanding what the appraiser evaluates can make the process easier to prepare for.

Knowing what to expect can make one of the more technical parts of a real estate transaction much easier to navigate.
