A home appraisal is a professional, independent estimate of what a property is worth in the current market. It is carried out by a licensed appraiser who inspects the home, studies recent sales of comparable properties, and produces a written report that states a single value figure. This number plays a central role in almost every major real estate transaction.
Lenders require an appraisal before approving most mortgages because they need to confirm that the property is worth at least as much as the loan being issued against it. Without this step, a lender would have no independent way to verify that the collateral backing the loan matches the borrowed amount.
Appraisals matter at almost every stage of homeownership. Buyers rely on them to confirm they are not overpaying. Sellers use them to set realistic listing prices. Homeowners refinancing a mortgage or applying for a home equity loan need an updated value to determine how much they can borrow. This guide walks through the entire appraisal process, typical costs, how value is calculated, the best online tools, and what to do if an appraisal comes back lower than expected.
What Is a Home Appraisal?
In simple terms, a home appraisal is a professional opinion of value. It is not the same as the price a seller is asking, and it is not the same as the value your local tax authority uses to calculate property tax. These three numbers, market value from an appraisal, listing price set by a seller, and assessed value used for taxation, can all be different, sometimes by a wide margin.
The listing price is a number chosen by the seller, often with input from a real estate agent, and it reflects what the seller hopes to achieve. The assessed value is set by a government office for tax purposes and is frequently lower than market value because it is updated less often. The appraised value is the only one of the three produced by an independent, licensed professional using a defined methodology, which is why lenders rely on it.
What Is an Appraiser?
A home appraiser is a state-licensed or state-certified professional trained to evaluate residential property and produce a formal valuation report. Appraisers complete required coursework, supervised experience hours, and a licensing exam before they can sign appraisal reports independently. Many appraisers also hold designations from professional bodies such as the Appraisal Institute, which signal additional training in specialized property types.
An appraiser’s job is to remain neutral. They do not work for the buyer or the seller. In a mortgage transaction, the appraiser is typically ordered through an appraisal management company at the lender’s request, which helps maintain independence from the people who have a financial interest in the outcome.
What Is the Purpose of a Home Appraisal?
The core purpose of a home appraisal is to confirm that a property’s value supports the amount of money being lent or invested against it. For a mortgage lender, this protects against issuing a loan larger than the collateral can justify. For a homeowner refinancing, it determines how much equity is available to borrow against. For a seller, an appraisal can validate or challenge an asking price before the home goes on the market. For an estate, divorce settlement, or tax dispute, an appraisal provides a defensible, documented value that can stand up to legal scrutiny.
How Does a Home Appraisal Work?
When Is a Home Appraisal Ordered?
An appraisal is most commonly ordered once a buyer and seller have signed a purchase agreement and the buyer’s mortgage application has moved into underwriting. The lender orders the appraisal directly, usually through a third-party appraisal management company, to keep the process independent from everyone involved in the sale. Appraisals are also ordered during refinancing, before approving a home equity loan or HELOC, for estate planning, during divorce proceedings, and when a property owner wants to challenge a tax assessment.
What Happens During a Home Appraisal?
On the day of the appraisal, the appraiser visits the property and walks through every room, taking photos and measurements as they go. They note the condition of major systems such as the roof, HVAC, plumbing, and electrical, and they record any visible defects, upgrades, or additions that are not reflected in public records. Outside, they assess the lot size, landscaping, exterior condition, and any structures such as garages, sheds, or pools.
After the site visit, the appraiser returns to their office to complete the analytical part of the job. This includes pulling recent sales data for comparable properties from the multiple listing service, adjusting those comparable prices for differences between the homes, and combining everything into a final report with a supported value conclusion.
How Is a Home Appraisal Done?
A complete appraisal generally follows five steps:
- Property inspection: A physical walkthrough to verify size, layout, condition, and any features that affect value.
- Comparable sales analysis: Identifying recently sold homes that are similar in size, age, location, and features, then adjusting their sale prices to account for differences.
- Neighborhood assessment: Reviewing the surrounding area for factors such as school quality, walkability, noise, and proximity to amenities.
- Local market conditions: Looking at whether the area is experiencing rising, stable, or falling prices, and how quickly homes are selling.
- Final valuation report: Combining all findings into a written document with a single value conclusion, supporting data, and photographs.
Home Appraisal Timeline
Most appraisals are completed within seven to ten days from the date they are ordered, though this can vary depending on appraiser availability and how busy the local market is. Here is a typical timeline:
Once the report is delivered, the lender’s underwriter reviews it as part of final loan approval. If the value supports the loan amount, the process moves to closing. If it does not, the buyer, seller, and lender will need to work through the options described later in this guide.
How Much Does a Home Appraisal Cost?
Appraisal costs vary based on property type, size, location, and how quickly the report is needed. As a general guide, a standard single-family home appraisal costs between $400 and $700. Condominiums and smaller properties tend to come in slightly lower, while larger homes, multi-family properties, and unique or luxury homes often cost more because they take longer to inspect and require more detailed comparable research.
Factors That Affect Home Appraisal Fees
- Property size: Larger homes take longer to measure and inspect, which increases the appraiser’s time on site.
- Property type: Condos and standard tract homes are usually quicker and cheaper to appraise than custom-built or multi-family properties.
- Geographic location: Appraisers in high-cost-of-living areas or remote rural locations often charge more due to travel time and limited availability.
- Complexity of valuation: Unusual layouts, recent additions not on record, acreage, or unique features require additional research and adjustment work.
- Urgent requests: Rush orders that need to be completed in 24 to 48 hours typically carry an additional rush fee.
Who Pays for the Home Appraisal?
In most mortgage transactions, the buyer pays for the appraisal as part of their closing costs, even though the lender is the one who orders it. The fee is usually collected upfront or rolled into the overall closing cost total. For refinances and home equity loans, the borrower pays the fee directly. In situations where a seller orders a pre-listing appraisal to support a pricing decision, the seller covers the cost themselves.
How Is a Home’s Appraised Value Determined?
The appraised value of a home is built primarily around the sales comparison approach. The appraiser identifies between three and six recently sold homes that closely match the subject property in location, size, age, and condition. They then make dollar-value adjustments for differences, such as adding value for an extra bathroom in the subject property or subtracting value if a comparable has a larger lot. The adjusted prices of the comparables are reconciled into a single supported value for the subject property.
Factors That Increase Appraisal Value
Several improvements and conditions tend to push an appraisal value upward, including a recently updated kitchen or bathroom, a new roof or HVAC system, additional usable square footage such as a finished basement, energy-efficient upgrades, strong curb appeal, and a location in a neighborhood with rising recent sale prices.
Factors That Lower Appraisal Value
On the other side, several issues commonly pull value down. Deferred maintenance, such as a roof nearing the end of its life or visible water damage, signals to an appraiser that near-term repair costs will reduce a buyer’s willingness to pay full price. Outdated systems, including old electrical panels, plumbing, or HVAC units, raise similar concerns. Location challenges, such as proximity to a busy road, industrial site, or flood zone, can permanently cap value regardless of the home’s condition. Declining market conditions, where recent comparable sales show falling prices, will also be reflected directly in the final value conclusion.
How to Estimate Your Home’s Value Before an Appraisal
Home Appraisal by Address
Many homeowners want to know what their property might be worth before officially ordering an appraisal. The simplest starting point is searching your address on major real estate platforms, which use automated valuation models to generate an estimate based on public records and recent nearby sales. These figures give a useful starting point, but they should not be treated as a substitute for a professional opinion, since automated models do not account for interior condition or recent renovations.
How to Find Out the Appraised Value of a Home
If a home has been appraised recently as part of a mortgage transaction, the official report is typically shared with the borrower by the lender, often through the loan portal or by email. For homes that have not been appraised recently, the closest publicly available figures are the county assessor’s valuation, which can usually be looked up for free on the county website, and recent comparable sales data, which real estate agents can pull from the multiple listing service on request.

Best Online Home Appraisal Tools and Calculators
How Online Home Appraisal Calculators Work
Online home value calculators use what is known as an automated valuation model (AVM). These tools pull data from public property records, tax assessments, and recent sales in the surrounding area, then run that information through a statistical model to produce an estimated value. The model looks for patterns, such as how price per square foot changes across a neighborhood, and applies those patterns to the subject property.
Pros and Cons of Instant Home Appraisal Tools
Instant online tools are free, fast, and useful for getting a general sense of value, particularly in markets with a high volume of recent sales data. Their main weakness is that they cannot see inside a home. Two identical homes on paper, with one freshly renovated and one untouched since the 1990s, will often receive very similar automated estimates despite a significant real difference in value. Automated tools also struggle in areas with few recent sales, unusual properties, or rural locations where comparable data is limited.
Best Home Appraisal Websites and Resources

Can You Get a Free Home Appraisal?
A formal, lender-accepted appraisal from a licensed appraiser is rarely free, since it represents several hours of professional work and carries legal liability for the appraiser. However, there are several free or low-cost ways to get a useful estimate of your home’s value.
Free Appraisal Options
- Comparative market analysis (CMA): Many real estate agents will prepare a free CMA, comparing your home to recently sold and currently listed properties nearby, in the hope of earning your business if you decide to sell.
- Online estimators: Automated valuation tools on major real estate portals provide instant, free estimates based on public data.
- Real estate agent valuations: Beyond a formal CMA, an experienced local agent can often give a verbal price range based on their day-to-day knowledge of the market.
Free Estimates vs Professional Appraisals
| Factor | Free Estimate (AVM or CMA) | Professional Appraisal |
|---|---|---|
| Cost | Free | $400 to $700+ |
| Includes interior inspection | No | Yes |
| Accepted by lenders | No | Yes |
| Typical accuracy range | Plus or minus 10 to 15% | Plus or minus 2 to 5% |
| Turnaround time | Instant | 7 to 10 days |
How to Find a Qualified Home Appraiser
Questions to Ask Before Hiring an Appraiser
If you are arranging your own appraisal outside of a lender-managed transaction, such as for an estate, a divorce, or a pre-listing valuation, it helps to ask a few key questions before hiring. Confirm how many years of experience the appraiser has in your specific neighborhood, ask whether they are familiar with your property type, such as a condo, multi-family, or rural property, request a sample of a recent report, and ask about turnaround time and total cost upfront, including any rush fees.
How to Verify Appraiser Credentials
Every state maintains a licensing board where you can verify that an appraiser holds an active license in good standing. Search the appraiser’s name and license number on your state’s appraisal licensing board website to confirm their status and check for any disciplinary history. You can also look for additional designations from professional associations such as the Appraisal Institute, which require ongoing education beyond the basic licensing requirements. Finally, online reviews from past clients can offer insight into an appraiser’s communication style, punctuality, and professionalism, though they should be weighed alongside official licensing verification rather than used on their own.
Home Appraisal Checklist: How to Prepare
Things to Do Before a Home Appraisal
A little preparation can help an appraiser see your home at its best and ensure nothing is missed during the inspection. Use this checklist in the days before your appointment:
Home Appraisal vs Home Inspection: What Is the Difference?
Buyers often confuse appraisals and inspections, but the two serve very different purposes. An appraisal determines what a home is worth. An inspection examines what condition a home is in and identifies potential problems. Both involve a professional visiting the property, but they are ordered by different parties, follow different processes, and produce different reports.
| Factor | Home Appraisal | Home Inspection |
|---|---|---|
| Purpose | Determine market value | Assess condition and identify issues |
| Ordered by | Lender, or owner for non-mortgage purposes | Buyer |
| Conducted by | Licensed appraiser | Certified home inspector |
| Outcome | Appraisal report with value conclusion | Inspection report listing condition and defects |
| Required for mortgage | Yes, in almost all cases | Optional, but strongly recommended |
It is worth noting that a home assessment, used by local government to calculate property tax, is a third and separate concept again. A tax assessment is neither a market value opinion like an appraisal, nor a condition report like an inspection. It is simply the figure a taxing authority uses to calculate your annual property tax bill, and it is often updated far less frequently than either an appraisal or current market prices.
Home Appraisals for Buying, Selling, and Refinancing
Home Appraisal When Buying a House
When you buy a home with a mortgage, the appraisal is ordered after your offer is accepted and your loan moves into processing. The lender uses the appraised value, together with your loan amount, to calculate the loan-to-value ratio, which influences your interest rate and whether mortgage insurance is required. If the appraisal comes back at or above the purchase price, the transaction proceeds as planned. If it comes back lower, additional steps may be needed before closing.
Home Sale Appraisal
Sellers sometimes order their own pre-listing appraisal before putting a home on the market. This can help set a realistic asking price, identify any issues that could affect value before potential buyers see them, and provide useful supporting documentation if a negotiation becomes difficult later in the process.
Home Appraisal for Refinance
When refinancing a mortgage, the lender orders a new appraisal to confirm the home’s current value, which determines your new loan-to-value ratio. A higher appraised value than expected can help you secure better rates, remove private mortgage insurance, or access more cash if you are doing a cash-out refinance. A lower than expected value can limit how much you are able to refinance or borrow against.
Home Equity Loan and HELOC Appraisals
Do You Need an Appraisal for a Home Equity Loan?
In most cases, yes. Because a home equity loan or HELOC is secured against the equity in your home, lenders need a current valuation to calculate exactly how much equity is available and how large a loan they can safely offer. Equity is calculated as your home’s current value minus the balance remaining on your existing mortgage, so an accurate value is essential to this calculation.
HELOC Appraisal Requirements
Does a home equity line of credit require an appraisal? Most lenders require some form of valuation, though it does not always need to be a full, in-person appraisal. Depending on the loan amount, your existing equity cushion, and the lender’s internal policies, they may accept a desktop appraisal based on data alone, a drive-by appraisal where the appraiser views only the exterior, or an automated valuation model for smaller loan amounts where the borrower clearly has substantial equity.
No-Appraisal Home Equity Loans
Some lenders offer no-appraisal home equity loans or lines of credit, typically for smaller loan amounts, for borrowers with a long history with the lender, or in cases where an automated valuation model can confidently support the requested amount without an on-site visit. While these options can save time and the cost of a formal appraisal, they are usually limited to lower loan-to-value ratios, meaning you may not be able to borrow as much against your equity as you could with a full appraisal.
What Happens If the Appraisal Comes in Low?
Understanding the Appraisal Gap
An appraisal gap occurs when the appraised value of a home comes in below the agreed purchase price. For example, if a buyer agrees to pay $500,000 for a home but the appraisal values it at $480,000, there is a $20,000 appraisal gap. Lenders will only loan based on the lower of the purchase price or the appraised value, so this gap becomes the buyer’s responsibility to address, often by increasing their cash contribution at closing.
Why this matters: A low appraisal does not necessarily mean the deal falls apart. In competitive markets, appraisal gaps are common, and many buyers prepare for this possibility ahead of time with appraisal gap coverage clauses in their offer.
Options for Buyers and Sellers
When an appraisal comes in low, there are typically four paths forward:
- Renegotiate the purchase price: The buyer and seller can agree to lower the price to match the appraised value, which is often the simplest solution if the seller is motivated.
- Increase the down payment: The buyer can cover the gap between the loan amount and the purchase price with additional cash, keeping the original price intact.
- Request a reconsideration of value: If the buyer’s agent believes the appraiser used inaccurate or poorly chosen comparable sales, they can submit a formal request with supporting data asking the appraiser to review and potentially revise the value.
- Challenge inaccurate comparables: Closely related to a reconsideration of value, this involves providing the appraiser with additional comparable sales that were not originally considered, particularly if they are more similar to the subject property than those used in the report.
What Happens If the Appraisal Is Higher Than the Offer?
When an appraisal comes back higher than the agreed purchase price, this is generally good news for the buyer. The lender will base the loan on the lower purchase price, since that is what the buyer is actually paying, which means the buyer immediately has more equity in the home than the price they paid would otherwise suggest. This instant equity can be useful for future refinancing or for meeting loan-to-value requirements on second mortgages down the line.
