One part of the Primary market is moving much faster than the national supply picture

The National Association of Realtors counted 4.9 months of supply across the U.S. That is the highest in over ten years. But in ZIP 02461, the Real Estate Data Aggregator measured just 1.3 months for the three months ending July 31, 2026. Those are two very different markets.

What this means for sellers in ZIP 02461: supply dropped 0.9 months from a year ago, according to the Real Estate Data Aggregator. Homes are not sitting. The Real Estate Data Aggregator found that 53.1% went under contract within two weeks of listing. That share rose 12.5 points from the same period in 2025.

What this means for buyers in ZIP 02461: you may not have much time to decide. The Real Estate Data Aggregator put the median days on market at 20 days. The Real Estate Data Aggregator also found that 46.2% of homes sold above list price. Nationally, rates are adding pressure too. Freddie Mac put the 30-year fixed rate at 7.28% as of October 1, 2026.

How the four ZIPs compare

ZIP 02460: fast and competitive

The Real Estate Data Aggregator counted 36 homes sold in ZIP 02460 for the three months ending July 31, 2026. That is up 2.9% from the same months of 2025. The median sale price dipped 4.9% to $1,530,500. Prices came down a little, but speed did not. The Real Estate Data Aggregator found 66.7% of homes went under contract within two weeks, up 28.5 points from a year ago. That is the highest two-week rate in the Primary market.

ZIP 02458: more choice, a bit more time

ZIP 02458 is the least tight of the four. The Real Estate Data Aggregator found 2.5 months of supply for the three months ending July 31, 2026, down 0.2 months from 2025. The median sale price rose 6.5% to $1,545,000. Homes took a median of 33 days to sell, 14 days longer than the same period a year ago. Still, the Real Estate Data Aggregator counted 48.8% of homes going under contract within two weeks. Buyers here have a little more room, but not a lot.

ZIP 02459: the highest prices, steady pace

ZIP 02459 had the highest median sale price in the Primary market. The Real Estate Data Aggregator put it at $2,075,000 for the three months ending July 31, 2026, up 4.3% from 2025. Sales rose 3% to 69 homes. Months of supply ticked up 0.3 to 2.1 months. Homes took a median of 26 days to sell. The Real Estate Data Aggregator found 44.3% went under contract within two weeks.

ZIP 02461: tightest supply, strong demand

ZIP 02461 is where the story is sharpest. The Real Estate Data Aggregator counted 39 homes sold in the three months ending July 31, 2026, up 50% from 2025. Supply fell to 1.3 months. The median sale price dropped 19.4% to $1,325,000. One client put it plainly: more homes sold, at lower prices, faster. The Real Estate Data Aggregator found the sale-to-list ratio at 102.4%, meaning homes still closed above asking on average.

The whole Primary market together

Across all four ZIPs, the Real Estate Data Aggregator counted 193 homes sold in the three months ending July 31, 2026, up 8.4% from 2025. There were 127 homes for sale, up 3.3%. New listings fell 9.3% to 185. Pending sales held nearly flat at 176, up 0.6%. More homes sold, but fewer new ones came on. That keeps pressure on buyers even as the national picture looks looser.

What the national picture adds

The National Association of Realtors reported 4.9 months of supply nationally, the highest in over ten years. Existing-home sales fell 2.0% month over month in August 2026, though they are up 1.6% year to date. Freddie Mac put the 30-year fixed rate at 7.28% as of October 1, 2026, and the 15-year at 6.60%. Realtor.com noted rates crossed 7% in late September for the first time since January 2025, and that active listings nationally are up 6.3% from a year ago.

What this means for buyers here: even with more supply nationally, local inventory is thin. Rates at 7.28% (Freddie Mac) add to the cost of waiting. In ZIP 02461, homes that are priced well are not waiting around.

What this means for sellers here: the national headlines about rising supply do not fully apply. In ZIP 02461, 53.1% of homes went under contract within two weeks, per the Real Estate Data Aggregator. Pricing still matters, though. ZIP 02461's median sale price fell 19.4% from a year ago. Not every home sold fast, and not every home sold at the same price.

One street can read very differently from the whole ZIP code. The numbers above cover broad areas. Your block, your home type, your price range, all of those can shift the picture. If you want to know what the data looks like for your specific address, let's team up and take a closer look together.
