The residential real estate market on Long Island saw home prices continue to rise in June 2025, with both Nassau and Suffolk counties reporting significant year-over-year increases in median sales prices, according to the latest data from the New York State Association of REALTORS® (NYSAR). However, the gains came alongside a continued dip in closed sales and only modest shifts in inventory.
In Nassau County, the median sales price climbed 6.8% from $772,500 in June 2024 to $825,000 last month. Suffolk County saw a 5.9% rise in its median home price, reaching $675,000 compared to $637,500 a year earlier. Both counties far surpassed the statewide median of $448,115, which rose 1.8% from June 2024, per NYSAR’s latest market report.
Despite the price growth, the number of homes sold declined across the board. Nassau reported 826 closings in June, an 11.0% decrease from 928 sales during the same month last year. Suffolk’s sales numbers dipped by 1.7%, from 1,107 to 1,088.
New listings were mixed. Nassau added 1,319 homes to the market in June, a 7.0% year-over-year increase from 1,233. Suffolk, by contrast, saw a slight 1.2% decrease, with 1,680 homes listed compared to 1,700 the previous June.
The overall number of homes available for sale remained relatively flat. Nassau’s inventory dropped 2.1% to 2,679 homes, while Suffolk ticked up slightly by 0.5%, rising to 3,611 homes. Supply—a measure of how long it would take to sell all inventory at the current pace of sales—declined in both counties. Nassau dropped from 3.3 to 3.2 months, while Suffolk fell from 3.4 to 3.2 months, indicating a tighter market.
