North Shore sales slowed overall, but not every part moved the same way

Real estate, North Shore

The Federal Housing Finance Agency reported that U.S. home prices rose 2.6% in the year ending July 2026. On the North Shore, the Real Estate Data Aggregator counted 306 homes sold across the area in the three months ending August 31, 2026. That was down 6.7% from the same months a year before. But that one number hides a lot. Some parts of the North Shore saw strong price gains and fast sales. One was nearly flat. One dipped. Where your home sits changes everything about how you should price it and when.

Mortgage rates climbed above 7% by the end of September, according to Realtor.com. That matters for sellers because buyers are more careful at that level. Nationally, Redfin reported that 14.5% of homebuying deals fell through in September, the highest share in their records. The North Shore is not immune to those pressures. But tight supply in some ZIP codes is still pushing prices up, even in that environment.

How each ZIP code moved

The Real Estate Data Aggregator tracked six ZIP codes on the North Shore for the three months ending August 31, 2026. The results were not uniform. Here is what each one showed.

Where prices climbed the most

ZIP code 10310 had the biggest price gain. The Real Estate Data Aggregator put the median sale price there at $767,000, up 20.8% from the same months in 2025. Supply was tight: only 3 months of inventory, and new listings fell 23.3% year over year. Fewer homes came to market, and the ones that did sold for more. That said, only 33 homes sold, and sales were down 19.5%. A smaller pool of buyers, but also a smaller pool of homes.

ZIP code 10303 was close behind. The Real Estate Data Aggregator counted a median sale price of $617,500, up 20.3% year over year. Homes there sold at 101.8% of list price on average, and 37.8% of homes sold above asking. New listings dropped 26.2%, the steepest fall of any ZIP code on the North Shore. Less competition among sellers is helping the ones who do list.

One ZIP code was nearly flat, and one dipped

ZIP code 10304 had a median sale price of $737,500, according to the Real Estate Data Aggregator. That was up just 0.1% from a year before, which is essentially flat. Homes sold there took a median of 59 days, 7 days longer than the year before. New listings rose 20.8%, the only ZIP code on the North Shore where that happened. More homes coming in, fewer going under contract, and prices barely moving. That combination asks for careful pricing.

ZIP code 10305 was the one area where prices actually dipped. The Real Estate Data Aggregator showed a median sale price of $720,000, down 4% from the same months in 2025. Homes sold in 42 days, 13 days faster than a year before, which is a bright spot. But only 21.4% of homes sold above list price, down 2.8 points from last year. Buyers there have a little more room to negotiate than they did.

Where homes sold fastest

ZIP code 10302 stood out for speed. The Real Estate Data Aggregator counted a median of just 26 days on market, 19 days shorter than a year before. That is the fastest of any ZIP code on the North Shore. Homes there sold at 100.6% of list price on average, and 45.8% sold above asking. That is the highest above-list share across the whole North Shore. Only 34 homes were for sale, and only 29 new listings came in. Very little to choose from, and buyers are competing for what is there.

ZIP code 10301: more sales, but slower

ZIP code 10301 had the most activity. The Real Estate Data Aggregator counted 67 homes sold, up 21.8% from a year before. The median sale price was $740,000, up 13.8%. Those are strong numbers. The catch is that homes sat for a median of 70 days, which was 14 days longer than last year. That is the slowest of any ZIP code on the North Shore. More homes are selling, but buyers are taking their time. Pricing right from day one matters more when days on market are climbing.

The wider picture: sellers and buyers nationally

Nationally, Redfin reported that sellers outnumbered buyers by 62.6% in September 2026. There were an estimated 1,510,784 home sellers in the U.S. market that month, the most since March 2020, against an estimated 928,892 buyers, the lowest level since 2013. Realtor.com reported that Northeast inventory rose 11.6% year over year in September 2026, while the Northeast median list price fell 3.8% over the same period. The North Shore is not the Northeast average, but those broader forces shape what buyers can afford and how confident they feel.

Pending sales across the full North Shore fell 19.9% year over year in the three months ending August 31, 2026, according to the Real Estate Data Aggregator. That is a meaningful drop. Fewer homes going under contract now means fewer closings ahead. It is not a reason to panic, but it is a reason to pay attention to how your home is positioned.

One more thing worth saying: these are ZIP code numbers. One street can read very differently from the whole ZIP. A block with more inventory, or a pocket with almost none, will behave like its own small market. The numbers here give you the direction. Your specific address tells the full story.
