A recent report showed that, as home sales have gone up, housing supply has been on the decline.
According to the New York State Association of REALTORSⓇ (NYSAR), Long Island home sales last month increased year over year — up by 3.4% in Nassau County and a 7.0% increase in Suffolk County. There were 910 homes sold in Nassau last month compared to 880 in October 2024; in Suffolk, 1,327 houses were sold, up from 1,240 the previous October.
Meanwhile, housing supply trended down sharply. Based on NYSAR’s data, Nassau’s inventory fell 9.4% to 2.9 months from 3.2 months last year and Suffolk only had a 3.0-month supply last month from 3.3 months in October 2024 — a decline of 9.1%. Both figures are below the state’s inventory, which has 3.4 months of supply. That is up 3.0% from October of the previous year, when inventory was 3.3 months.
Nassau and Suffolk also saw drops in homes for sale, NYSAR said. Nassau went from having 2,639 homes on the market in October 2024 to 2,474 last month, a 6.3% decline. Suffolk also saw its inventory shrink from 3,600 to 3,380 homes on the market; that was a decrease of 6.1%.
In other news, there were fewer new listings on Long Island. In Nassau, the number was 1,033, which was only 0.1% less than the previous October’s figure of 1.034. Suffolk had 1,431 new listings in October 2025, a 6.9% decrease year over year; in October 2024, there were 1,537 new listings in Suffolk, NYSAR data showed.
Finally, home prices are still going up. Nassau’s median home prices rose 6.7% on an annual basis from $766,000 to $817,500, while, in Suffolk, median home prices went up 4.5% to $679,500 from $650,000 the previous October. Both figures exceed the state’s median sales price of $431,000, which is 5.1% higher than last year, when its was $410,000, according to NYSAR.
