TL;DR
A home appraisal is an independent valuation ordered by your lender to confirm the property's worth supports the loan amount.- Appraisers evaluate the home's condition, square footage, comparable sales, location, and any upgrades or deficiencies.
- The three valuation methods are the sales comparison approach (most common for residential), the cost approach, and the income approach.
- If the appraisal comes in below your offer price, you can renegotiate, cover the gap, challenge the appraisal, or walk away.
- An experienced agent who understands the appraisal process can save you thousands by preparing for and responding to appraisal outcomes strategically.
Jump to the Low Appraisal Decision Matrix
You found the house, made an offer, negotiated the terms, and the seller accepted. Everything feels like it is falling into place. Then you hear two words that stop the momentum: home appraisal.
For most buyers, the appraisal is the part of the home buying process they understand the least. It happens behind the scenes, controlled by someone you did not choose, and the outcome can reshape your entire deal. Yet understanding what appraisers actually evaluate, how they arrive at a number, and what your options are if the result is disappointing gives you a significant advantage at the negotiation table.
This guide walks through the complete home appraisal process from the moment your lender orders it to the day you receive the report, covering exactly what appraisers look for inside and outside the home, how the three valuation approaches work, and the specific steps you can take when an appraisal comes in lower than your offer price.
What Is a Home Appraisal and Why Does It Matter?
A home appraisal is a professional, independent assessment of a property's market value conducted by a licensed or certified appraiser. When you apply for a mortgage, your lender orders the appraisal to verify that the home you are buying is worth enough to serve as collateral for the loan.
Think of it as the lender's safety check. If you default on the mortgage, the lender needs to recover their investment by selling the property. The appraisal confirms the home's value supports that recovery.
The appraisal is separate from the home inspection. While an inspection examines the home's physical condition for defects and safety concerns, the appraisal focuses strictly on market value. Both are important steps in protecting your investment, but they serve different purposes and are conducted by different professionals.
Important distinction: The buyer pays for the appraisal (typically included in closing costs), but the lender selects the appraiser. Under federal regulations established after the 2008 financial crisis, lenders must use third-party appraisal management companies (AMCs) to maintain independence between the loan officer and the appraiser.

The appraisal process follows a predictable sequence, though most of the work happens without the buyer present. Here is what to expect from start to finish.
Lender Orders the Appraisal
After your offer is accepted and you have formally applied for your mortgage, the lender submits an appraisal order through an appraisal management company. The AMC assigns a licensed appraiser who is familiar with the local market. This typically happens within a few days of your loan application.
Appraiser Schedules the Visit
The appraiser contacts the listing agent or seller to schedule an on-site inspection. This visit typically lasts 30 minutes to an hour for a standard single-family home, though larger or more complex properties may require additional time. As the buyer, you generally do not need to be present.
On-Site Property Inspection
The appraiser walks through the home, measuring rooms, noting condition, photographing key features, and identifying anything that could affect value. They also inspect the exterior, garage, yard, and overall lot. The appraiser is looking at both the physical structure and how the home compares to similar properties in the area.
Comparable Sales Research
Back at the office, the appraiser researches recent sales of similar properties (called "comps") within the area. They look for homes sold within the last three to six months that match the subject property in size, age, condition, and location. Adjustments are made for differences between the comps and the subject property.
Report Delivered to Lender
The appraiser completes a formal report (most commonly on the Uniform Residential Appraisal Report form, also known as Fannie Mae Form 1004) and submits it to the lender. The report includes the appraised value, the methodology used, the comparable sales analysis, and any conditions or comments. You are entitled to receive a copy of this report.
What Do Appraisers Look For?
Appraisers evaluate dozens of factors, but they generally fall into three categories: the property itself, the comparable sales data, and the surrounding neighborhood. Understanding these categories helps you anticipate the result and, if you are selling, prepare your home to support the highest defensible value.
Inside the Home
The interior inspection is more than a casual walkthrough. Appraisers are trained to evaluate:
- Total living area and layout: The appraiser measures the gross living area (GLA) and notes the number of bedrooms, bathrooms, and functional layout. Finished basements and attic spaces may or may not count toward GLA depending on local standards.
- Overall condition and quality: They rate the home's condition on a scale from C1 (new construction) to C6 (significant deferred maintenance). Cosmetic issues like dated wallpaper or worn carpet have a smaller impact than structural or mechanical problems.
- Kitchen and bathroom updates: Renovated kitchens and bathrooms are among the highest-value improvements. The appraiser notes the quality of cabinets, countertops, appliances, and fixtures.
- Mechanical systems: Age and condition of the HVAC, plumbing, electrical, and water heater. Outdated systems (such as knob-and-tube wiring or polybutylene piping) can trigger lender concerns.
- Health and safety items: For FHA and VA loans especially, the appraiser checks for peeling paint (in homes built before 1978), functioning smoke detectors, adequate handrails, and safe access.
Outside the Home
- Roof condition: The appraiser notes the roof material, approximate age, and visible condition. A roof nearing the end of its useful life may result in a value adjustment or a lender requirement for replacement.
- Foundation and structure: Visible cracks, settling, or water intrusion can significantly impact value.
- Lot size and features: Garage, driveway, fencing, landscaping, and outbuildings are all documented.
- External influences: Proximity to busy roads, power lines, commercial properties, or environmental hazards can affect the appraisal negatively.
Neighborhood and Market Factors
- Comparable recent sales: This is the single most influential factor. The appraiser relies on three to five recently sold properties that are similar in size, style, age, and location.
- Market trends: Is the neighborhood appreciating, stable, or declining? The appraiser notes the direction and pace of price changes.
- School districts, amenities, and location quality: While these cannot be quantified precisely, they are reflected in the comparable sales data the appraiser selects.
Common misconception: Many buyers (and sellers) assume that the amount they spent on renovations will be reflected dollar-for-dollar in the appraisal. That is rarely the case. An appraiser values improvements based on what the market will pay for them, not what they cost to install. A $60,000 kitchen remodel might only add $30,000 to $40,000 in appraised value, depending on the neighborhood.
The Three Valuation Approaches Appraisers Use
Appraisers are trained in three distinct methods for determining value. For residential purchases, one approach dominates, but understanding all three helps you see how the final number is derived.
1. Sales Comparison Approach (Most Common for Residential)
This is the primary method used in nearly all residential appraisals. The appraiser identifies three to five comparable properties (comps) that have sold recently in the same area. They then adjust each comp's sale price up or down to account for differences with the subject property.
For example, if a comp sold for $400,000 but has one fewer bathroom than the subject property, the appraiser might add $10,000 to that comp's adjusted value. If the comp has a larger lot, the appraiser might subtract $5,000. After adjusting all comps, the appraiser reconciles the adjusted values to arrive at a final estimate.
The quality of the comps drives the quality of the appraisal. In neighborhoods with abundant recent sales of similar homes, appraisals tend to be straightforward. In rural areas or for unique properties where comparable data is scarce, the process becomes more subjective.
2. Cost Approach
The cost approach estimates what it would cost to rebuild the home from scratch, minus depreciation, plus the land value. This method is most useful for new construction or special-purpose properties where comparable sales are limited.
Formula: Land Value + (Replacement Cost - Depreciation) = Property Value
This approach is less commonly the primary valuation method for existing homes because depreciation estimates involve significant judgment, and the cost to build does not always align with what buyers will pay.
3. Income Approach
Used primarily for rental and investment properties, the income approach values the property based on the income it can generate. The appraiser estimates the gross rental income, subtracts vacancy losses and operating expenses, and applies a capitalization rate to determine value.
If you are purchasing a property you plan to rent out, the appraiser may include this approach alongside the sales comparison method.

A low appraisal, where the appraised value is less than your agreed-upon purchase price, is one of the most stressful situations a buyer can face. It means your lender will only finance a loan based on the lower appraised value, leaving a gap between what the bank will lend and what you agreed to pay.
For example, if you offered $425,000 on a home and the appraisal comes in at $405,000, there is a $20,000 appraisal gap. Your lender will base your loan on $405,000, which means you would need to cover that $20,000 difference out of pocket, renegotiate, or find another solution.
You generally have four options. Each one has different financial implications, and the right choice depends on your cash position, how competitive the market is, and how badly you want this particular home.
Option 1: Renegotiate the Purchase Price
The most common response to a low appraisal is to go back to the seller and negotiate a price reduction. The appraisal report provides objective, third-party evidence that the home is not worth the original offer price, which gives you leverage.
Your success here depends heavily on market conditions. In a buyer's market with plenty of inventory, sellers are more likely to reduce the price to keep the deal together. In a competitive seller's market, the seller may have backup offers and refuse to budge.
Option 2: Pay the Appraisal Gap
If you have the cash and believe the home is worth more than the appraised value (perhaps due to recent improvements not yet reflected in comp data), you can bring additional funds to closing to cover the gap. Some buyers in highly competitive markets include appraisal gap coverage clauses in their original offers, committing upfront to cover a certain amount if the appraisal falls short.
Option 3: Challenge the Appraisal
If you or your agent believe the appraiser made errors or overlooked relevant comparable sales, you can request a reconsideration of value (ROV) through your lender. This is not an appeal in the traditional sense. You submit additional comparable sales data, correct factual errors (wrong square footage, missing upgrades), or provide context the appraiser may have missed.
According to Fannie Mae guidelines, the lender must review any credible evidence submitted and decide whether a revision is warranted. The original appraiser may adjust the value, or the lender may order a second appraisal.
Option 4: Walk Away
If your contract includes an appraisal contingency (and most do), you can cancel the purchase and get your earnest money deposit back. This is the cleanest exit, but it means starting your home search over.
Agent advantage: A skilled buyer's agent can often resolve low appraisals without losing the deal. They know how to assemble a comp package for the appraiser before the visit, challenge a report with additional data, and negotiate with the seller's agent to split the difference. Working with a knowledgeable agent during this process can mean the difference between saving the deal and losing the home.

Appraisal vs. Offer Price: Understanding the Relationship
Your offer price and the appraised value are determined by entirely different forces. The offer price is driven by what you, as a buyer, are willing to pay based on your emotions, motivations, and competitive pressure from other buyers. The appraised value is driven by comparable sales data and an objective analysis of the property's features.
These two numbers can diverge significantly, particularly in markets that are moving quickly. In a hot market with bidding wars, buyers routinely offer above asking price, which can push the offer above what the appraisal data supports. In a cooling market, homes may be listed above their true market value, and the appraisal catches that discrepancy.
| Factor | Offer Price | Appraised Value |
|---|---|---|
| Determined by | Buyer and seller negotiation | Licensed appraiser using market data |
| Influenced by | Competition, urgency, emotional attachment | Comparable sales, property condition, location |
| Timeframe considered | Current market moment | 3 to 6 months of historical sales |
| Impact on loan | Determines total purchase commitment | Determines maximum loan amount lender will approve |
| Can exceed the other? | Yes, common in competitive markets | Yes, possible if seller underpriced the home |
How Appraisal Gaps Work and How to Plan for Them
An appraisal gap is the difference between the appraised value and the contract price when the appraisal comes in lower. In competitive markets, buyers sometimes include an appraisal gap guarantee (also called appraisal gap coverage) in their offer to make it more attractive to sellers.
An appraisal gap guarantee is a written commitment from the buyer to cover some or all of the difference between the appraised value and the offer price using personal funds. For example, you might offer $430,000 with a $15,000 appraisal gap guarantee, meaning you will pay up to $15,000 out of pocket if the appraisal falls short.
Cash impact: Remember that the gap money is on top of your down payment, not instead of it. If you are putting 20% down on a $430,000 home ($86,000) and the appraisal comes in at $415,000 with a $15,000 gap guarantee, you would need $86,000 + $15,000 = $101,000 at closing, plus your standard closing costs. Make sure your cash reserves can handle the worst-case scenario before including gap coverage in your offer.
How to Increase Your Home's Appraised Value
Whether you are a seller preparing for a listing or a buyer hoping the appraisal supports your offer price, there are steps that can help the appraisal reflect the home's full value.
For Sellers (and Buyers Who Can Coordinate with Sellers)
- Provide a list of improvements: Give the appraiser a written summary of all upgrades, renovations, and repairs completed during your ownership, including dates and approximate costs. Appraisers cannot adjust for upgrades they do not know about.
- Make necessary repairs before the appraisal: Visible damage, deferred maintenance, and non-functioning systems reduce the condition rating. Even small repairs (fixing leaky faucets, replacing broken window screens, patching drywall) contribute to a better condition assessment.
- Clean and declutter: While appraisers are trained to look past cosmetics, a clean, well-maintained home creates a positive impression and can influence the subjective elements of the rating.
- Ensure access to all areas: Appraisers need to inspect every room, including the attic, basement, and garage. Blocked access can lead to assumptions that are not in your favor.
For Buyers and Their Agents
- Prepare a comp package: Your agent can compile a list of favorable comparable sales and present them to the appraiser (or the listing agent to share). This is not about pressuring the appraiser but ensuring they have access to the most relevant data.
- Document neighborhood improvements: If the area has seen new development, school improvements, or infrastructure upgrades that might not be reflected in older comp data, note those changes.
- Be strategic about timing: If several strong sales are about to close in the neighborhood, waiting a few weeks for that data to become available can improve the comparable pool.

FHA and VA Appraisals Have Additional Requirements
If you are using an FHA or VA loan, the appraisal includes minimum property requirements (MPRs) that go beyond a conventional appraisal. FHA appraisals, governed by HUD Handbook 4000.1, require that the home be safe, sound, and secure. This means the appraiser checks for items such as functioning utilities, adequate heating, no peeling paint in pre-1978 homes, proper roof drainage, and no health or safety hazards.
VA appraisals follow similar minimum property requirements outlined in the VA Lender's Handbook. The VA also assigns specific appraisers from its roster, and VA appraisals carry a "Tidewater" process where the appraiser notifies the lender if the value appears likely to fall short, giving the buyer's agent an opportunity to submit additional comps before the final report is issued.
Appraisal Waivers
In some cases, lenders may offer an appraisal waiver, bypassing the in-person appraisal entirely. These waivers are typically available through Fannie Mae's system (known as a "value acceptance" or property inspection waiver) when the automated underwriting system determines the loan risk is low enough. Waivers are more common for borrowers with strong credit, larger down payments, and properties in areas with abundant data.
While an appraisal waiver can save time and the $300 to $600 fee, buyers should consider whether the protection the appraisal provides (an independent value check) is worth giving up. If you are paying above asking price or buying in a volatile market, the appraisal serves as an important safeguard.
New Construction Appraisals
Appraising new construction presents unique challenges because the home does not yet exist (or is not yet complete) at the time of the initial appraisal. The appraiser typically reviews the blueprints, specifications, and comparable completed homes in the area. A second appraisal or a completion inspection may be required once the home is finished.
Frequently Asked Questions About Home Appraisals
How long does a home appraisal take from start to finish?
The on-site visit typically takes 30 minutes to an hour. From the time your lender orders the appraisal to when the report is delivered, expect 7 to 14 business days, though this can vary by market demand and appraiser availability. In some busy markets, it may take longer.
Who pays for the home appraisal?
The buyer pays for the appraisal. The cost typically ranges from $300 to $600 for a standard single-family home and is included in your closing costs. More complex properties, multi-unit buildings, or rush orders may cost more. You pay this fee even if the appraisal comes in low or the deal falls through.
Can I attend the appraisal inspection?
You have the right to be present, though it is not common for buyers to attend. Some appraisers prefer to work without the buyer present to maintain objectivity. If you do attend, avoid following the appraiser around or commenting on the home's value. Your agent can be more effective by providing comp data to the listing agent ahead of the visit.
What happens if the appraisal comes in higher than the purchase price?
A high appraisal is good news for the buyer. It means you are buying the home for less than its appraised market value, giving you instant equity. The lender uses the lower of the appraised value or purchase price to determine the loan amount, so a higher appraisal does not change your loan terms. The seller is not entitled to know the appraisal came in above the contract price.
Can a seller back out because of a low appraisal?
Generally, no. The appraisal contingency protects the buyer, not the seller. The seller is bound by the purchase contract unless the buyer invokes the appraisal contingency to cancel. However, if the buyer requests a price reduction and the seller refuses, and the buyer walks away, the seller is then free to relist the property.
How is a home appraisal different from a home inspection?
An appraisal determines the home's market value for the lender. An inspection evaluates the home's physical condition for the buyer. The appraiser focuses on what the home is worth based on comps and features. The inspector focuses on what is broken, damaged, or potentially hazardous. Both are important, but they serve different parties and different purposes. Learn more about the home inspection process.
Can I get a second appraisal if I disagree with the first one?
You can request a reconsideration of value from your lender by submitting additional comparable sales or correcting factual errors. If that does not resolve the issue, some lenders will order a second appraisal, though this varies by lender policy. You may also switch lenders and start a new loan application, which would involve a new appraisal, though this costs time and money.
Do appraisers look at the purchase price before appraising the home?
Yes, appraisers typically receive a copy of the purchase contract and know the agreed-upon price. This is standard practice and does not compromise the appraisal's independence. The appraiser still must support their valuation with comparable sales data. Knowing the contract price helps the appraiser understand the transaction context, but it should not, and professionally does not, dictate the final value conclusion.
