Is the housing market slowing down in Nassau County, NY?
Yes — sales activity in Nassau County, NY is down. 1,590 homes sold during May 2026, against 1,811 in the same months a year earlier, a drop of 12%.
This page is about how many homes changed hands, not what they cost. The two move separately: prices are set by the homes that did sell, and volume tells you how many people managed to transact at all. A market can hold its prices while activity quietly drains out of it.
The change clears both tests we require before naming a direction: it is more than 3% in relative terms, and it is larger than the ordinary month-to-month variation you would expect on a market that sells 1,590 homes at a time.
The longer view, all measured over the May window so the season is held constant: 1,879 homes sold two years ago, 1,811 last year, 1,590 now. Activity is meaningfully below where it was two years ago.
What is on the shelf next to what is selling: 5,400 homes were on the market in Nassau County, NY, and 1,590 sold. At that pace it would take about 3.4 months to clear them all. Buyers and sellers are about evenly matched right now.
Every comparison on this page is to the SAME calendar months a year earlier, never to last month. Home sales roughly double between January and May in most of the country, so a month-over-month reading would tell you about the season and nothing about the market.
