If the county says your home is worth more than you believe it would have sold for on the assessment date, you are not crazy for asking questions. A rising tax bill can feel especially brutal in Fairfax County, Arlington County, and Loudoun County, where property values and the cost of living are already high.
The key question is not whether your tax bill feels unfair. The question is whether the county's assessed value, property record, or equalization is supportable for the required date. A property tax appeal appraisal gives you an independent, property-specific value opinion to compare with the county's mass appraisal.
These are high-income, high-cost Northern Virginia markets. The 2024 American Community Survey reports median household income of $177,567 in Loudoun County, $154,545 in Fairfax County, and $142,114 in Arlington County. High incomes do not make an incorrect assessment harmless. They make precision more important because small valuation errors can translate into real money.

The 2026 deadlines below have passed. Use this table to understand the sequence, then verify the next assessment cycle directly with the county before ordering an appraisal or filing an appeal.
| County | Assessment date | 2026 first review deadline | 2026 board deadline | Evidence that often matters |
|---|---|---|---|---|
| Fairfax | January 1 | April 1 administrative appeal | June 1 Board of Equalization | Correct property record, neighborhood and school boundary, condition, lot utility, and comparable sales |
| Arlington | January 1 | March 2 department review | April 15 Board of Equalization | Micro-location, renovation quality, parking, lot utility, condo floor, exposure, fees, and building differences |
| Loudoun | January 1 | March 16 assessment review | June 1 Board of Equalization | Land utility, acreage, well and septic, outbuildings, new construction, restrictions, condition, and market segment |
Call the assessment office first if the property record is factually wrong. Call an appraiser when the dispute is primarily about market value, comparable sales, condition, site influence, renovation quality, or a property feature the mass appraisal model may not measure well.
Send the assessment notice, county property record, the value being challenged, the appeal stage, the filing deadline, recent photos, renovation history, and any county comparable sales. That allows a quick review of whether the possible tax savings and valuation issue justify the cost of an appraisal.
A county assessment is produced through mass appraisal. It applies models and neighborhood-level data across thousands of properties. A tax appeal appraisal is different. It analyzes your property, the relevant market, and the correct effective date.
A strong appeal is not a complaint about taxes. It is a valuation argument supported by facts. The report must explain why the county's number may be wrong and what the property was more likely worth as of the required date.
Fairfax County is a collection of distinct submarkets, not one uniform housing market. A Vienna teardown, a Reston condo, a McLean luxury home, a Burke split-level, and a Clifton acreage property require different comparable selection and adjustments.
For the 2026 assessment year, Fairfax County listed April 1 as the administrative appeal deadline and June 1 as the Board of Equalization deadline. Those 2026 deadlines have passed. Deadlines change by assessment year, so confirm the current schedule on the official Fairfax County assessment appeals page.
A Fairfax appeal appraisal should address the county record, the required January 1 valuation date, the relevant neighborhood or competing market area, and the sales that best reflect the subject property.
Arlington values can change block by block and building by building. Metro access, school boundaries, redevelopment, lot utility, renovation quality, parking, floor level, view, and condominium fees can materially affect value. Broad county averages are rarely enough.
For 2026, Arlington listed March 2 as the Department of Real Estate Assessments review deadline and April 15 as the Board of Equalization deadline. Those 2026 deadlines have passed. Verify the current dates and filing instructions on the official Arlington County assessment appeals page.
An Arlington appeal appraisal must be specific about the property's micro-location and market segment. A nearby sale can still be a weak comparable if it has different access, condition, site utility, building characteristics, or buyer appeal.
Loudoun County includes planned communities, older towns, rural acreage, luxury homes, new construction, equestrian properties, and homes with wells, septic systems, outbuildings, conservation restrictions, or unusual land characteristics. That range makes property-specific analysis essential.
For 2026, Loudoun listed March 16 as the real property assessment review deadline and June 1 as the Board of Equalization deadline. Those 2026 deadlines have passed. Confirm the current process on the official Loudoun County assessment appeal page.
A Loudoun appeal appraisal should separate land and improvement issues, analyze the property's actual site utility, and avoid treating all acreage or all new construction as equivalent.
An appraisal does not guarantee a reduction. The county or Board of Equalization makes the decision. A credible appraiser must remain independent and cannot promise a target value.
An appraisal may make sense when the potential tax savings justify the cost, the county record is materially wrong, the property has unusual features, or the assessment appears unsupported by the best comparable sales. It may not make sense when the disputed value is small, the deadline has passed with no remaining remedy, or the market evidence strongly supports the assessment.
Before ordering, gather the assessment notice, property record, recent photos, renovation history, any contractor invoices or permits, and the county's comparable sales if available. Tell me the county, filing stage, deadline, and value you are challenging.
No. The assessment is generally produced through mass appraisal for taxation. An independent appraisal is property-specific and prepared for a defined intended use and effective date.
Depending on the jurisdiction and facts, a review can result in no change, a decrease, or an increase. Read the county's rules before filing.
Often yes. Condition, renovations, quality, layout, and deferred maintenance can affect value. The appropriate scope depends on the assignment and available evidence.
The county's required valuation date, not automatically today's date. Confirm the effective date before ordering.
An automated estimate can be a starting point, but it is not a substitute for a property-specific appraisal when condition, site, renovations, or local market differences matter.
No. I provide an independent value opinion and supporting analysis. The county or appeal board decides the assessment.
Estate and Date of Death Appraisals: Current or retrospective fair market value for executors, heirs, attorneys, accountants, probate matters, and basis documentation.
Divorce Appraisals: Independent current or retrospective valuation for marital dissolution, settlement discussions, mediation, and litigation support.
Trust Appraisals: Valuation for trust administration, successor trustee inventory, beneficiary distribution, transfer, sale, tax planning, or a required prior date.
PMI Removal Appraisals: Independent equity analysis when a homeowner needs to understand current value before approaching the mortgage servicer.
Fairfax County Tax Appeal Appraisals: Market evidence and valuation analysis connected to a real estate assessment challenge.
Pre-Listing and Pre-Offer Appraisals: Independent value guidance before pricing a home, accepting an offer, or making a cash purchase.
Fix-and-Flip and Renovation Appraisals: Current and prospective value analysis for investors, homeowners, and renovation decisions.
Medical and Disability Modification Appraisals: Before-and-after value analysis when an accountant or attorney requests support connected to a medically necessary home improvement.
What should I say when I call?
Tell me the property address, who requested the appraisal, why it is needed, whether the value must be current or as of a prior date, and whether an attorney, CPA, lender, trustee, executor, or other professional will use the report.
Does every appraisal require an interior inspection?
No. The appropriate scope depends on the assignment, available information, intended use, and professional requirements. Some assignments need a full interior and exterior inspection. Others may support a different agreed scope. I will explain what is appropriate before accepting the assignment.
Can you appraise a Fairfax County property as of a past date?
Yes. Retrospective appraisals are frequently required for date of death, estate, trust, divorce, tax, and legal matters. The report analyzes the market and property information relevant to the required effective date.
Can I order the appraisal if a mortgage lender requested it?
Ask the lender first. Appraisals used for mortgage lending generally must be ordered through the lender or its appraisal management process. I can still help you understand what the lender is asking for.
How do I get started?
Call or text 703-350-2542. I will identify the correct appraisal type, confirm the scope, fee, effective date, inspection needs, and expected timeline before the assignment begins.
34 years and 15,000+ appraisals: Experience matters when the difference between two sales is not obvious from a spreadsheet. I have completed residential appraisal assignments across Northern Virginia for legal, tax, financial, and real estate decisions.
Fairfax County roots: I was born at Inova Fairfax Hospital, grew up in Fairfax County, built my own home here, and have watched local neighborhoods and housing markets change over decades.
Arlington market detail: Arlington requires close attention to Metro access, redevelopment, school boundaries, lot utility, condominium characteristics, parking, and block-level location differences.
Loudoun property complexity: Loudoun work can involve new construction, planned communities, rural acreage, equestrian features, wells, septic systems, outbuildings, conservation restrictions, and fast-changing submarkets.
Independent analysis: I do not start with a target number. I define the appraisal problem, research the relevant market, inspect the property when appropriate, and report the value the evidence supports.
Direct communication: You work directly with the appraiser. Call or text 703-350-2542 and explain the county, assessment, appeal stage, deadline, and reason you believe the value is wrong.
These counties are expensive and economically significant, but accuracy still comes down to the individual property. The 2024 American Community Survey reports median household income of $177,567 in Loudoun County, $154,545 in Fairfax County, and $142,114 in Arlington County. Those figures support calling these high-income, high-cost markets. They do not prove any individual assessment is correct.
Ready to start? Send the property address, assessment notice, filing deadline, and county record. I will help determine whether a property tax appeal appraisal is the right next step.
