Summary answer: It depends on the segment. Arlington single-family homes are projected to rise about 3.8% in 2026 on constrained inventory, while condos fell 7.4% in 2025 and are projected to recover only about 2.1% this year. The county's own figures show the average home value at $882,900 in 2026, and overall assessments rose about 1.1%. So prices are not collapsing and not surging. They are moving in two different directions depending on what you buy.
I'm Johnny with JQ Real Estate. Let me explain what is behind these numbers and what they mean for you.
The recent trajectory by segment
| Segment | 2025 | 2026 Outlook |
|---|---|---|
| Condos | Down 7.4% | About +2.1% (early recovery) |
| Single-family homes | Strong appreciation | About +3.8% projected; inventory up 27.8% |
| County-wide assessments | Up about 1.1% for calendar year 2026 (county figure) |
Why the two segments diverge
Single-family homes in Arlington are scarce, and the county has limited room to add them. Demand from high-income federal, defense, and consulting households keeps competition strong even with higher mortgage rates. Condos are a different story. Many were bought or built in a lower-rate era, supply has been abundant in some corridors, and buyers are more rate-sensitive at lower price points. High dues and condo financing restrictions also hold back demand. The result is a market where one side is firm and the other has softened.
What the county's numbers say
Arlington's Department of Real Estate Assessments reported overall property values up about 1.1% for 2026, compared with about 2% growth the prior year. The county's tax rate then rose two cents to $1.053, so the average bill rose more than the assessment growth alone suggests. This does not mean market prices rose 1.1%, since assessments use a different method and timing, but it shows that growth has slowed.
Is the condo drop a warning or an opportunity?
It can be both. A 7.4% decline is meaningful, and condo values may not bounce back quickly. At the same time, it creates leverage for buyers who plan to hold for several years and who choose buildings carefully. The risks are building-specific: weak reserves, special assessments, high investor concentration, and financing eligibility. A well-run building in a strong location tends to hold value better than one with financial problems.
What it means if you are buying
- Condo buyers: negotiate, ask for credits, and review building finances carefully.
- Single-family buyers: expect competition, and prepare to move quickly with a strong offer.
- All buyers: focus on the payment you can afford, not on predicting the market.
What it means if you are selling
Price to the segment you are in. A single-family seller can price near recent strong sales, while a condo seller should use current comparables and avoid pricing off 2024. Sellers who price correctly from day one sell faster and for more than those who start high and cut repeatedly.
What to watch next
- Mortgage rates. Falling rates could bring buyers back to condos.
- Inventory levels. Single-family inventory is up 27.8%, which could soften competition.
- Federal employment and contracts. Changes in staffing and budgets move demand.
- Ownership costs. A rising tax rate and condo dues affect affordability.
An example of reading the data
Suppose you are watching a two-bedroom condo in a mid-rise near Court House. A year ago, a similar unit sold for $600,000. Last month, a comparable unit sold for $565,000, and another is listed at $575,000 after a $10,000 reduction. That is a local data point more useful than any countywide percentage. A single-family home nearby, by contrast, may have sold last month for 4% above asking. The comparison shows how different the two markets feel even a few blocks apart.
