Long Island Single-Family Home Market Update: June 2026 | Nassau & Suffolk

This Long Island single-family home market update shows that home values remained strong through June 2026, while limited inventory continued to support sellers in both Nassau and Suffolk Counties.

June also brought a useful shift in the numbers: closed sales increased compared with June 2025 in both counties. At the same time, Suffolk County homes took longer to sell during the month. The result is a market that still favors well-positioned sellers, but one in which buyers are paying close attention to price, condition, and value.

Long Island Single-Family Market: The Big Picture

Over the rolling 12-month period through June 2026, the median single-family sales price reached $850,000 in Nassau County, up 5.5%, and $710,000 in Suffolk County, up 5.2%.

Inventory remained below the prior year in both counties. Nassau inventory declined 2.3%, while Suffolk inventory declined 4.3%. That shortage of available homes continues to support prices, even though rolling 12-month closed sales were slightly lower.

The June monthly snapshot was encouraging: closed sales increased 1.5% in Nassau and 3.7% in Suffolk compared with June 2025. Still, the counties did not move in exactly the same way. Nassau’s June median-price gain was a more moderate 2.9%, while Suffolk’s median rose 7.1% even as days on market increased. This is why local conditions—and not just a countywide headline—matter when preparing a home for sale.

Nassau County Single-Family Home Market

For the rolling 12 months ending June 2026, Nassau County’s median single-family sales price increased from $806,000 to $850,000, a gain of 5.5%.

Nassau sellers received 99.3% of their original list price on average. That was 0.4 percentage points below the prior rolling period, but it still indicates that accurately priced homes were selling very close to their original asking price.

June snapshot: Suffolk’s monthly median price reached $750,000, up 7.1% from June 2025. Closed sales increased 3.7%, while inventory fell a substantial 11.6%. However, days on market rose from 39 to 44 days, an increase of 12.8%.

Countywide Data Is Helpful, But Your Town Matters More

Countywide statistics show the overall direction of the market, but conditions can differ substantially by town, neighborhood, school district, price range, property type, and condition.

A useful local market review should consider recent comparable sales, active competition, pending activity, buyer demand, and the home’s specific features. Online estimates and countywide averages cannot account for all of those factors.
