Summary answer: What your Arlington home is worth depends far more on its property type, building or street, and condition than on any countywide figure. The county's own average home value is $882,900 for 2026, the blended market median runs roughly $750,000 to $860,000, single-family homes often exceed $1 million, and condos in corridors like Columbia Pike, Ballston, and Clarendon commonly run from about $300,000 to $575,000. Condos fell 7.4% in 2025, while single-family homes are projected to rise about 3.8%. Only recent comparable sales can pin down your number.
I'm Johnny with JQ Real Estate. Let me explain how I value an Arlington home and why the online numbers disagree.
Why the published numbers differ so much
| Source | What It Measures | Why It Can Mislead |
|---|---|---|
| County assessment | The county's estimate of value as of January 1 | Uses a different method and timing than a sale; can lag the market. |
| Blended median price | Condos and houses combined | Hides the split between $300K condos and $1M+ houses. |
| Automated online estimate | An algorithm's guess | Cannot see condition, updates, or building issues. |
| Closed comparable sales | What similar homes actually sold for | The most reliable guide when properly adjusted. |
How I actually value an Arlington home
- Select true comparables. Same property type, similar size, same or nearby building or street, sold within the last three to six months.
- Adjust for differences. Condition, updates, floor, view, parking, lot size, and finished basement all change value.
- Check the active and pending competition. Your home competes with what is on the market today.
- Consider location factors. Walking distance to Metro, noise, and traffic matter.
- Account for market direction. Condos fell in 2025 and single-family is projected to rise, so older comps may overstate or understate today's value.
Factors that move value in Arlington
- Property type. Condos, townhomes, and detached homes occupy different price tiers.
- Metro walkability. Homes within walking distance of Rosslyn, Court House, Clarendon, Virginia Square, Ballston, Pentagon City, or Crystal City consistently price and sell faster.
- Condition and updates. Kitchens, baths, flooring, roof, and HVAC age strongly affect price.
- Building health. For condos, reserves, dues, and special assessments affect value.
- Financing eligibility. A condo that is FHA and VA approved reaches more buyers.
Beware of automated estimates
Online estimates use algorithms that cannot see inside your home or know about your upgrades. In a county where condos and houses are moving in opposite directions, they can miss by a lot, and they tend to lag a changing market. Use them as a rough guide, not as a price.
Your assessment is not your value
The county's assessment determines your tax bill, with the 2026 rate at $1.053 per $100, but it is not a market appraisal. Assessments can lag sales, and the county reported overall values up about 1.1% for 2026. If your assessment is far below or above what similar homes are selling for, that is information, but it does not set your listing price.
What a professional analysis includes
A comparative market analysis from a local agent should show closed comps with adjustments, active competition, pending sales, absorption, and a recommended price range with a strategy. It should also explain what could push your value up or down, such as completing certain repairs or timing the listing.
Common mistakes sellers make
- Pricing from last year's comps, particularly for condos.
- Relying on a neighbor's asking price rather than their sale price.
- Overvaluing improvements that buyers do not pay for.
- Ignoring building issues that lenders will flag for condo buyers.
An example of the difference a CMA makes
Two owners in Arlington each see a median near $800,000 and assume their home is worth that. One owns a 750 square foot one-bedroom condo with original finishes. The other owns a renovated 2,800 square foot single-family home on a quiet street. Recent closed comps put the condo around $380,000 to $420,000 and the house near $1,250,000 to $1,350,000. The countywide figure was not wrong. It just did not apply to either one. A proper analysis narrows the range to something you can price from.
