One part of the Primary market is still moving very fast

Freddie Mac put the average 30-year fixed rate at 7.40% as of October 8, 2026. That is not a small number. Yet one ZIP code in the Primary market is acting like rates barely matter.

The Real Estate Data Aggregator counted just 0.9 months of supply in ZIP 22205 for the three months ending August 31, 2026. That is the tightest reading of any ZIP in this market. Buyers there have very little to choose from.

The Real Estate Data Aggregator found that 70.8% of homes in ZIP 22205 went under contract within two weeks of listing. That share is up 24 points from the same period in 2025. Speed like that means buyers face real competition, and sellers still need a sharp price to make the most of it.

How ZIP 22205 stacks up against the rest

These numbers cover the three months ending August 31, 2026. The story changes a lot by ZIP code.

What is driving ZIP 22205

The Real Estate Data Aggregator shows only 18 homes for sale in ZIP 22205 during those three months. That is down 18.2% from a year before. Fewer homes, same demand: that is why prices and speed are both up.

The wider market tells a different story

Across all five ZIP codes together, the Real Estate Data Aggregator counted 427 homes sold in the three months ending August 31, 2026. That is down 9.9% from a year before. Homes for sale across the whole market rose 18.8%. So supply is growing in some areas even as ZIP 22205 stays extremely tight.

ZIP 22204 is the clearest contrast. The Real Estate Data Aggregator found 3.5 months of supply there, up 1.5 months from a year before. Homes took a median 51 days to sell, which is 12 days longer than last year. Not every part of this market moves fast.

Nationally, the National Association of Realtors reported 4.9 months of supply at the current sales pace, the highest level in over ten years. The Primary market as a whole sits well below that, but ZIP 22204 at 3.5 months is moving closer to the national picture.

What this means if you own or are buying

In ZIP 22205, the Real Estate Data Aggregator shows homes selling at 102.6% of list price on average. That is up 3.7 points from a year before. Pricing too high still costs you: even in a fast market, buyers notice when a number is out of step.

In ZIP 22204, the Real Estate Data Aggregator shows inventory up 51.2% from a year before. More choices for buyers there means sellers have less room to push price. The median there was $645,000, up just 4%.

Freddie Mac's 7.40% rate as of October 8, 2026 is real pressure on budgets everywhere. But ZIP 22205 shows that tight supply can outweigh rate headwinds in the right spot.
