One part of the Primary market is moving much faster than the rest
Speed: that is the number that changes what you do next. The Real Estate Data Aggregator counted homes in ZIP 02460 sitting on the market a median of just 15 days, in the three months ending August 31, 2026. That is the fastest in the Primary market. Price your home wrong there, and you miss a very short window.
For comparison, Redfin reported the median U.S. home took 49 days to sell. ZIP 02460 ran at less than a third of that pace.
How the four ZIP codes compare on speed
ZIP 02458 clocked in at 34 days, according to the Real Estate Data Aggregator. That is more than twice the pace of 02460. And it got slower: 11 days longer than the same period in 2025.
Under contract in two weeks: a big gap
Speed shows up another way too. The Real Estate Data Aggregator found that 65.2% of homes in ZIP 02460 went under contract within two weeks of listing. That share jumped 36.6 points from a year before.
ZIP 02459 was on the other end. Only 29.6% of homes there went under contract in two weeks. That share fell 6.8 points from a year ago, per the Real Estate Data Aggregator.
What this means if you are a homeowner
In ZIP 02460, buyers are deciding fast. The Real Estate Data Aggregator showed 57.6% of homes sold above list price there. That is up 27.9 points from a year before. Prep and pricing need to be right from day one, not day five.
In ZIP 02458, you have more time. But the Real Estate Data Aggregator showed days on market rose 11 days year over year. A slower market still rewards good pricing. It just punishes overpricing more quietly.
What this means if you are a buyer
In ZIP 02460, the Real Estate Data Aggregator counted just 20 homes for sale. With 65.2% going under contract in two weeks, you need to be ready to move. Pre-approval and a clear budget are not optional there.
In ZIP 02459, the Real Estate Data Aggregator counted 45 homes for sale, up 73.1% from a year ago. You have more choices and more time to look. That is a different kind of search.
The broader picture
Freddie Mac put the 30-year fixed rate at 7.40% as of October 15, 2026. That shapes what buyers can afford across all four ZIP codes. The National Association of Realtors reported existing-home sales nationally at 3.99 million units in September 2026, with inventory at 1.60 million homes.
Across the whole Primary market, the Real Estate Data Aggregator counted 179 homes sold in the three months ending August 31, 2026. That is up 6.5% from the same months of 2025. Sales are happening. They are just happening at very different speeds depending on the ZIP.

- ZIP 02460 is the fastest-moving part of the Primary market right now.
- Fifteen days median, nearly two-thirds of homes under contract in two weeks.
- ZIP 02458 is running at 34 days and slowing.
- The other two ZIP codes sit in between.
- These are not small differences.
- They change how you prepare, how you price, and how quickly you need to act.
One more thing: these are ZIP-level numbers. One street can read very differently from the ZIP code around it. If you want to know where your address actually sits, let's team up and look at it together.
