The Short Version
- Roughly 10% of home appraisals come in below the contract price, according to Fannie Mae data, and appraisal issues caused 5% of recent contract delays per the National Association of Realtors.
- Fresh cookies, flower arrangements, and last-minute staging do nothing for your appraisal value. Appraisers are trained to ignore cosmetics and focus on measurable, comparable factors.
- What actually moves the needle: a documented list of upgrades with dates and costs, recent comparable sales your agent can hand to the appraiser, full access to every space (especially mechanicals), and resolved deferred maintenance.
- Federal Appraiser Independence Requirements bar sellers and agents from selecting or pressuring the appraiser, but you can absolutely provide objective documentation that supports your home's value.
- If the appraisal comes in low, you have four real options: request a reconsideration of value with new comps, renegotiate, ask the buyer to cover the gap, or relist with another buyer pool.
You've accepted an offer. The closing date is on the calendar. Then your listing agent calls with one number that can rearrange the entire deal: the appraised value. If it lands at or above your contract price, the financing moves forward and you close on schedule. If it lands below, the buyer's lender will only fund the loan against the lower number, and you and the buyer are suddenly negotiating a gap that didn't exist 48 hours earlier.
The good news for sellers is that low appraisals are uncommon. According to data referenced by the Appraisal Institute and Fannie Mae, more than 90% of appraisals confirm or exceed the agreed-upon contract price. The better news is that the things you can actually do to improve your odds are nothing like the advice you'll find on most "appraisal day prep" lists. Baking cookies, lighting a candle, and putting fresh flowers on the kitchen island will not change your appraised value. The factors that will change it are dull, documentary, and entirely within your control.
This guide separates the appraisal myths from the mechanics. We'll walk through what appraisers are actually trained to evaluate, the cosmetic prep that doesn't matter, the documentation that does, and a ranked checklist you can use to prepare. If the appraisal comes in low, we'll cover exactly what your options look like from the seller's side of the table.
What Appraisers Actually Evaluate Before Your Home Appraisal
To prepare for a home appraisal, it helps to understand what an appraiser is contractually required to do. The appraiser is hired by the buyer's lender, not by the buyer or seller, and is bound by the Uniform Standards of Professional Appraisal Practice (USPAP). Their job is to deliver an objective opinion of market value so the lender can confirm the property is adequate collateral for the loan. According to the Appraisal Institute, residential appraisers can use any of three valuation approaches.
The Three Valuation Approaches
Sales Comparison Approach
The appraiser identifies three to six recently sold homes (typically within the last six months and within one mile) that closely match yours on bed/bath count, square footage, age, lot size, and condition. They make line-item adjustments for differences and arrive at a supported value range. For nearly every owner-occupied resale, this is the approach that drives the final number.
Cost Approach
The appraiser estimates what it would cost to rebuild your home today from scratch, deducts depreciation for age and condition, then adds the land value. This is most relevant for new construction, unique custom homes, or properties where few comparable sales exist.
Income Approach
Used for income-producing properties, the appraiser values the home based on the rental income it can generate relative to comparable rentals. This typically applies to multifamily, investment, or short-term rental properties, not standard owner-occupied homes.
What Appraisers Physically Inspect
During the on-site visit, which usually takes between 30 and 60 minutes for a single-family home, the appraiser is documenting a defined set of objective characteristics. They measure exterior dimensions to confirm gross living area, count bedrooms and bathrooms, note the foundation type, and assess the condition of the roof, exterior, mechanicals (HVAC, water heater, electrical), and major interior systems. They photograph each room and most exterior elevations. They note material quality (laminate vs. hardwood, builder-grade vs. upgraded fixtures), the age and condition of finishes, and any updates that look recent.
None of this involves smelling cookies, admiring flowers, or being charmed by a clean countertop.

Find a Top Listing AgentHome Appraisal Myths That Don't Influence Value
Walk through any "how to prepare for your home appraisal" search result and you'll see the same advice repeated across blogs that all borrowed from each other: bake cookies, put out fresh flowers, light a candle, declutter every surface, leave classical music playing softly in the background. None of this changes your appraised value. Some of it is borrowed from open-house staging advice, which is a buyer-emotion exercise and has no overlap with an appraiser's job. Some of it is just wrong. Here are the myths worth retiring before appraisal day.
Baking cookies, scenting candles, or fresh flowers will help
Appraisers are trained to ignore sensory staging. They are explicitly instructed not to factor scent, mood, or atmosphere into a valuation. A pleasant smell does not make the comparable sales worth more.
Deep-cleaning will boost your appraisal
A clean home is a courtesy and makes it easier to photograph, but appraisers do not adjust value for cleanliness unless the condition is so deteriorated that it indicates deferred maintenance or health/safety issues.
Personal touches and decor make a difference
Family photos, paint colors, furniture style, and personal taste do not enter the valuation. The appraiser is comparing structural and measurable characteristics to other recent sales, not your interior design choices.
You can influence the appraiser with charm or hospitality
Federal Appraiser Independence Requirements published by Fannie Mae explicitly prohibit any party with a financial interest in the transaction from attempting to influence the appraiser through "coercion, extortion, collusion, compensation, inducement, intimidation, bribery, or in any other manner." Polite hospitality is fine. Anything that looks like persuasion is not just unhelpful, it can void the report.
A last-minute paint job or cosmetic refresh will lift the value
Cosmetic updates done in the week before the appraisal rarely affect the number. Material upgrades that affect value (new kitchen, new bathroom, replaced HVAC) take months to install and require permits and documentation to count. A coat of paint on the day of will not.
Hiding clutter will hide problems
Appraisers are trained to look behind boxes and into closets. They open mechanical room doors, check the HVAC and water heater, and photograph crawl spaces. Strategically hiding a moisture stain or a damaged subfloor is not a strategy; it's a delayed problem.
The line you cannot cross
You can hand the appraiser objective documentation: improvement lists with receipts, permit records, your agent's comp packet, and a fact sheet about the property. You cannot push for a number, mention what the buyer is paying, ask the appraiser to "make it work," or imply that the value needs to land somewhere specific. Crossing that line is an Appraiser Independence violation and can compromise the entire transaction.
What Actually Influences Your Home Appraisal Value
Now to the substance. These are the seller-side actions that genuinely change the outcome of a home appraisal. Some of them are about giving the appraiser better information. Some are about ensuring nothing on the property reads as a problem. None of them involve scented candles.
1. A Documented List of Comparable Sales
This is the single highest-leverage thing a seller (working through their listing agent) can do. The appraiser will pull their own comps, but they are a stranger to your neighborhood, working from MLS records, and may not know which recent sales reflect actual market conditions versus distressed transactions, off-market deals, or properties with significant differences that aren't obvious in the data.
Your listing agent should prepare a one-page comp packet with three to five strong comparable sales from the last 90 to 180 days, ideally with brief notes on why each one supports your home's value. The comps should be similar in size, age, condition, and proximity. Hand it to the appraiser at the property visit, professionally and without commentary. If you need help understanding what makes a strong comp, our guide to how to read a comparative market analysis walks through the same fundamentals appraisers use.
2. A Written Improvements List with Dates and Costs
If you've replaced the roof, upgraded the HVAC, remodeled the kitchen, added square footage, replaced windows, finished the basement, or done anything else of substance during your ownership, document it. The appraiser cannot adjust for improvements they don't see or don't know about. A simple one-page summary with the year completed, contractor name, and approximate cost is sufficient. Include receipts or permits if you have them readily available, but a written list is enough to prompt the adjustments.
For perspective on which improvements typically return the most value at resale, our analysis of which home renovations give you the best ROI breaks down the categories appraisers tend to credit.
3. Full, Unobstructed Access to Every Space
An appraiser will not climb over furniture to inspect a crawl space, move boxes to access a water heater, or wait while you find a key to the basement. Anything the appraiser cannot access is documented as "not inspected," which usually leads to an assumption that the unseen area is in average condition at best. Before the appointment, ensure clear access to: the attic hatch, the crawl space, the mechanical room (HVAC, water heater, electrical panel), every interior room including closets, the garage and any outbuildings, and the entire exterior perimeter.
4. Resolved Deferred Maintenance
Deferred maintenance is the category appraisers genuinely flag. A leaking roof, a non-functional HVAC system, broken windows, rotted exterior trim, peeling paint (especially on pre-1978 homes where lead paint compliance becomes a factor), missing handrails, electrical hazards, plumbing leaks, and signs of moisture intrusion all show up in the report and translate to value adjustments or repair conditions. None of these are cosmetic. Fixing them before the appraisal is not staging, it's eliminating discount triggers.
5. Accurate Square Footage Documentation
If your home's recorded square footage in tax records differs from its actual measurement (a finished basement that isn't in the assessor data, an addition that wasn't permitted properly, or a measurement error from a prior listing), provide documentation. Appraisers measure exterior dimensions and calculate gross living area according to ANSI Z765 standards. If you have a recent professional measurement, an architect's plans, or evidence of a permitted addition, give it to them. Square footage discrepancies are a common reason appraisals deviate from what sellers expect.
6. Permit Documentation for Past Work
Renovations and additions done without permits can be discounted heavily or excluded entirely from the value calculation. If you have permit records for past work, especially additions, garage conversions, or substantial remodels, hand those to the appraiser. If work was done without permits, talk to your listing agent before the appraisal about whether to disclose, whether to seek retroactive permitting, and how to position the work.
7. Real Curb Appeal (Structural, Not Cosmetic)
Curb appeal does affect appraisals, but not in the way most articles suggest. A fresh coat of paint on the front door does almost nothing. What matters is whether the exterior reads as well-maintained: clean gutters that are obviously intact, a roof without visible damage, a driveway and walkway without major cracks, a yard without dead trees or major neglect, exterior trim that isn't rotting. The appraiser is photographing the exterior and noting condition; their impression here informs the overall condition rating that flows into the final number.
8. A Property Fact Sheet
Pull together a single page with the year built, square footage, lot size, bed/bath count, garage configuration, HVAC age and type, water heater age, roof age and material, school district, HOA details if applicable, and any features that aren't obvious from the exterior (whole-house generator, solar panels with ownership documentation, water filtration, smart-home wiring, finished basement square footage). The appraiser will appreciate the time savings and reference your numbers when their measurements come close.

What to Do If Your Home Appraisal Comes In Low
Despite good preparation, appraisals occasionally land below the contract price. When that happens, the lender will only finance the lower number, and the buyer needs to either bring more cash to closing, renegotiate, or walk away. Here are your real options as a seller.
Request a Reconsideration of Value (ROV)
If you and your agent identify factual errors in the appraisal (wrong square footage, missed bedrooms, comparables that don't actually compare, missing improvement adjustments), the buyer's lender can submit a formal Reconsideration of Value request. You'll need to provide specific, documented errors and ideally three or four better comparable sales the appraiser didn't use. The lender, not the seller, controls this process. Disagreement with the conclusion is not a basis for an ROV. Factual error is.
Renegotiate the Contract Price
If the appraisal is legitimately reflecting current market conditions and your contract price was aspirational, the cleanest path is to lower the price to the appraised value. This keeps the buyer in the deal, preserves their financing, and avoids relisting risk. Whether this makes sense depends on the size of the gap and how confident you are another buyer would value the home differently.
Ask the Buyer to Cover the Gap
The buyer can choose to bring additional cash to closing to bridge the appraisal gap. They are under no obligation to do so unless their contract included an appraisal gap coverage clause specifying an amount. In a slower market, asking the buyer to absorb the entire gap is often a non-starter. In a tighter market, a partial split (buyer covers half, you reduce the price by half) is a common compromise.
Terminate and Relist
If the gap is large, the buyer won't budge, and you have reason to believe a different buyer or a different appraiser would arrive at a higher number, terminating and relisting is an option. The new listing will be subject to a new appraisal, but it will also reset your days-on-market and there's no guarantee the next appraisal lands differently. This is usually the last option, not the first.
For a deeper walkthrough of each option, including timeline expectations and how appraisal gap clauses work in practice, our complete guide to your four options when a low appraisal arrives covers each scenario in detail.
The market value vs. appraised value question
It's worth understanding that appraised value and market value are not the same number, even though both attempt to measure the same thing. Appraisals are backward-looking (based on closed comparable sales) while market value is what a willing buyer is paying right now. In rising markets, appraisals can lag. In flat markets, they tend to align. Our analysis of why appraised value and market value diverge explains the structural reasons this gap exists.
How a Strong Listing Agent Improves Your Appraisal Outcome
The single biggest variable in your appraisal outcome that isn't already determined by your home and your local market is the listing agent you hired. A high-performing agent does three things that directly support the appraised value: they price the home in a range the comps can actually defend, they prepare and deliver a professional comp packet to the appraiser, and they know how to manage a Reconsideration of Value request if the number comes in low.
| What the Agent Does | Why It Affects the Appraisal |
|---|---|
| Prices the home using a defensible CMA | Reduces the risk of contract price exceeding what current comps can support, which is the primary cause of low appraisals. |
| Prepares a one-page comp packet for the appraiser | Gives the appraiser better comparable sales than a pure MLS pull, especially in markets with limited transaction data. |
| Documents improvements, permits, and feature upgrades | Ensures every value-adjusting feature is on the appraiser's radar and contributes to the final number. |
| Manages access and timing for the property visit | Eliminates "not inspected" notations that lead to conservative condition assumptions. |
| Handles communication with the appraiser professionally | Maintains compliance with Appraiser Independence Requirements while ensuring documentation is delivered. |
| Initiates and supports a Reconsideration of Value if needed | Knows how to identify factual errors, source supporting comps, and submit the request through the lender's process. |
Agents who close 50+ transactions per year see appraisal outcomes patterns that part-time agents simply don't encounter. They know which appraisers are common in your market, which property types tend to receive conservative valuations, and which improvement categories are credited consistently versus discounted.

How long does a home appraisal take?
The on-site portion of a home appraisal typically takes 30 to 60 minutes for a standard single-family home. Larger or more complex properties (custom homes, multi-acre lots, multiple structures) can take longer. The appraiser then spends several additional hours off-site analyzing comparable sales, making adjustments, and writing the report. From order to delivered report, expect a typical turnaround of one to two weeks, though that can extend in busy markets.
Should I be present during the home appraisal?
You can be, but it isn't required and many appraisers prefer that you aren't. If you are present, give the appraiser space to do their job, answer factual questions if asked, and hand over any documentation you've prepared at the start of the visit. Avoid following them through the home or commenting on what they're inspecting. Many sellers leave the home with their listing agent present, which is also a common arrangement.
Can I influence the home appraisal as a seller?
Not in the persuasive sense. Federal Appraiser Independence Requirements explicitly bar any party with a financial interest from attempting to influence the appraiser's opinion of value through pressure, suggestion, or compensation. You can absolutely provide the appraiser with factual documentation: comparable sales your agent has prepared, an improvements list with costs, permit records, and a property fact sheet. The distinction is providing information versus exerting influence.
What is the difference between a pre-listing appraisal and the buyer's appraisal?
A pre-listing appraisal is one you commission and pay for before listing your home, typically costing $350 to $550. The buyer's appraisal is ordered by the buyer's lender, paid for by the buyer, and is the one that determines loan approval. A pre-listing appraisal can help you price the home and provide supporting documentation, but it does not replace or guarantee the buyer's appraisal.
Do home improvements always increase the appraised value?
Not dollar-for-dollar, and not all improvements are credited equally. Kitchen remodels, bathroom updates, HVAC and roof replacements, and added square footage typically receive value adjustments. Over-improvements that exceed neighborhood norms (a $200,000 kitchen in a $400,000 home market) usually return only a fraction of cost. Cosmetic refreshes done in the weeks before sale rarely move the appraisal at all.
How often do home appraisals come in low?
According to Fannie Mae data referenced by industry sources, approximately 10% of home appraisals come in below the contract price. The other roughly 90% confirm or exceed the agreed-upon price. National Association of Realtors survey data from late 2025 attributed about 5% of recent contract delays to appraisal issues. The rate varies meaningfully by market conditions, property type, and price segment.
What happens if the buyer waived the appraisal contingency?
If the buyer waived the appraisal contingency in their offer, they are contractually obligated to proceed with the purchase even if the appraisal comes in low. They will need to bring additional cash to closing to cover the gap between the appraised value (which limits the loan amount) and the contract price. From the seller's perspective, this is the strongest position; the buyer cannot use a low appraisal to renegotiate or back out.
Can I get a second appraisal if the first one comes in low?
The seller cannot order a second appraisal that the buyer's lender will accept. The lender's appraisal is the one that governs the loan. However, the buyer's lender can be asked to order a second appraisal through the Reconsideration of Value process if there are documented factual errors in the first report. Some buyers choose to pay for an entirely new appraisal through a different lender, though that typically requires restarting the loan application. Reasonable people can disagree about the appraised value, but the lender's number is the one that controls the financing.
