Are you wondering how an appraisal could make or break your home sale or purchase in Fairfax? You are not alone. Appraisals can feel mysterious, yet they have a big impact on financing, pricing, and timelines. In this guide, you will learn what appraisers do, how the process works in Northern Virginia, which Fairfax factors influence value, how to prepare, and what to do if the number comes in low. Let’s dive in.
What a home appraisal is
An appraisal is an independent, written estimate of a home’s market value completed by a licensed or certified appraiser. Lenders use it to measure risk and set the maximum loan amount. For buyers and sellers, it is an objective check against the contract price.
Appraisers follow the Uniform Standards of Professional Appraisal Practice and comply with rules set by state licensing authorities. For loans backed by Fannie Mae, Freddie Mac, FHA, or VA, appraisers also follow program-specific requirements for scope and documentation.
Keep these distinctions in mind:
- Appraised value vs assessed value: An appraisal estimates market value for a transaction. An assessment is for property taxes and is set by the local assessor on a different schedule.
- Appraiser vs home inspector: Appraisers estimate value. Inspectors evaluate condition and systems in detail. An appraisal is not a home inspection.
Who orders it and who pays
For purchase loans, your lender orders the appraisal as part of mortgage underwriting. The buyer typically pays the appraisal fee as a closing cost. Some sellers choose a pre-listing appraisal to help set price expectations, but the lender-ordered appraisal for the buyer’s loan is independent.
Timeline in Fairfax
Appraisals are usually scheduled after contract ratification during the loan contingency period. The on-site visit often takes one to a few hours. The written report is commonly delivered within several days to two weeks, depending on local demand and appraiser availability.
What appraisers evaluate
For a standard on-site appraisal, the appraiser completes an interior and exterior walkthrough. They confirm room counts and square footage, note overall condition, observe major systems that are visible, and document features with photos. They also note readily observable health or safety items, especially when the loan program requires it.
The final report typically includes a property and neighborhood description, site and improvement details, comparable sales with adjustments, photos, market condition comments, and an opinion of value. For most single-family purchases delivered to Fannie Mae or Freddie Mac, appraisers use a standardized form called the Uniform Residential Appraisal Report.
How value is determined
- Sales Comparison Approach: This is the primary method for single-family homes. The appraiser selects recent closed sales that are similar and nearby, then adjusts for differences in size, age, condition, lot, parking, basement, and more.
- Cost Approach: More common for newer or unique homes. It estimates the cost to rebuild minus depreciation, plus land value.
- Income Approach: Used when the property produces income. It is less common for typical single-family residences.
Appraisers prefer comps that are recent, local, and similar in key features. In a fast-moving market, very recent sales carry more weight. In a slower market with fewer sales, the window for comps may stretch longer.
Types of appraisal products
- Full on-site appraisal: Standard for most purchase loans, with interior inspection and the full report.
- Desktop or hybrid appraisal: Some analysis is done from the desk, with data, photos, or limited site observations. These are more common with refinances when allowed by investor rules.
- Appraisal waiver or automated valuation model: In lower-risk scenarios, the lender may accept a waiver. This is less common for purchase loans in active markets.
Fairfax factors that influence value
Northern Virginia buyers weigh lifestyle, commute, and community access. Appraisers consider the same market forces that drive demand.
- Employment and transit: Proximity to Washington, D.C., Tysons, Reston, and major employers, plus access to Metro, commuter rail, and key highways, often supports higher price per square foot.
- Amenities and planning: Neighborhood character, walkability, parks and trails, and shopping or dining hubs like Tysons and Mosaic District can boost marketability.
- Schools: School boundaries within Fairfax County Public Schools are an important demand factor for many buyers and can influence value trends in a neighborhood.
- Property details: Lot size and usable yard space, tree cover and privacy, interior updates to kitchens and baths, roof and HVAC age, and permitted additions or finished basements all matter. Properly documented permits with Fairfax County for major work help support value.
- Parking and storage: Garage spaces and driveway length are meaningful in suburban settings.
- Restrictions and overlays: Historic or conservation overlays and HOA rules can affect the buyer pool and value.
- Environmental and noise: Proximity to major highways or flight paths may reduce appeal for some buyers. Properties in mapped flood zones can face added scrutiny.
How to prepare for an appraisal
A smooth appraisal starts with access, clarity, and documentation. Aim to present your home and its history accurately.
Gather documents
- Comparable sales the listing agent used to price the home
- Receipts and permits for major improvements or additions
- A written list of upgrades and special features
- HOA documents if applicable
- Rental history or lease if the home is an investment
- Notes on easements, flood zone status, or boundary issues, plus any recent inspection reports
Present the property well
- Ensure easy interior access and keep utilities on
- Clean and declutter main rooms and highlight improvements
- Make simple fixes like replacing burned-out bulbs or repairing minor leaks
- Mow the lawn and tidy landscaping for curb appeal
- Clear access to the garage, parking, and storage for measurements
What your agent can and cannot do
Your agent can share facts, comparable MLS data, permits, and a property feature sheet. The appraiser must remain independent and cannot be pressured to hit a target value. Lender rules and appraisal standards prohibit undue influence.
FHA and VA loan considerations
FHA and VA transactions include program-specific minimum property standards. Appraisers must note required repairs to meet those standards, and lenders may require completion before closing. Timelines can run longer, and the report may include a list of repairs if issues are found.
If the appraisal comes in low
A value below the contract price is frustrating, but you have options.
Why it happens
- The price exceeds available comps
- The appraiser selected different or more conservative comps
- Data errors in the report, such as square footage or bedroom count
- Unpermitted work or deferred condition
- Market shifts between contract and appraisal
What you can do
- Renegotiate the purchase price to match the appraised value
- Bring cash to cover the gap between the loan limit and contract price
- Request a seller concession to help bridge the gap
- Ask your lender for a Reconsideration of Value by submitting better comps or correcting errors
- Discuss whether a second appraisal or review is appropriate under lender rules
- Use the appraisal contingency, if included, to revisit terms or exit as the contract allows
When waivers or desktops apply
Appraisal waivers and desktop or hybrid products are more common in low-risk refinances when allowed by investor guidelines. In active purchase markets or for unique properties, full on-site appraisals remain standard.
