Summary answer: It depends heavily on property type right now, more than almost any other factor. Arlington's median sale price sits around $818K–$857K depending on the exact data source and time window, but that blends two very different stories: single-family homes are appreciating steadily (up 3.8% projected for 2026) while condos are still recovering from a 7.4% decline in 2025. Your specific number depends far more on which segment you're in than on a single county-wide average.
I'm Johnny with JQ Real Estate. Let me walk through how I'd actually approach valuing your home right now.
Why the county-wide number can mislead you
| Segment | 2025 Trend | 2026 Trend |
|---|---|---|
| Single-family | Strong, steady growth | +3.8% projected |
| Condo | -7.4% | +2.1% (early recovery) |
If you own a single-family home, your value has very likely continued climbing. If you own a condo, your value may have softened over the past year before beginning to stabilize — a meaningfully different picture than the blended county average suggests.
What actually determines your specific number
- Recent comparable sales — homes similar to yours that actually sold in the last 30–60 days, not list prices of active competitors
- Property type — single-family vs. condo behave differently enough right now that this is the single biggest factor
- Building-specific factors for condos — HOA health, building age, and amenities vary significantly even within the same neighborhood
- Condition and updates — Arlington's inventory has grown, giving buyers more choice, which means move-in-ready condition matters more than it did a few years ago
- Days on market trend in your specific area — homes are averaging around 24–36 days depending on the source and segment
Why an automated estimate can be especially unreliable right now
Online estimate tools generally lag behind fast-moving trend shifts — they're built on historical patterns and can be slow to reflect a segment like condos moving through a real correction and early recovery. If your estimate dropped noticeably, it may simply be catching up to the broader condo trend rather than reflecting something specific about your unit.
What this means if you're thinking about selling
Given inventory is up significantly in both segments, pricing accurately from day one matters more than it has in recent years — buyers now have more options to compare against, and overpriced listings are more likely to sit and eventually require a price cut.
