Long Island home prices reached a new high in the third quarter of 2026, even as the number of homes for sale remained well below typical levels. For buyers, that means fewer options and a need to be ready when the right home appears. For sellers, limited competition can support strong pricing, but preparation and a realistic asking price still matter.
The latest numbers: record prices, limited choice
The median home price on mainland Long Island reached $782,000 in Q3 2026, a record and an increase of 4.3% from a year earlier, according to Q3 market data. Total listings stood at about 5,053, roughly 35.8% below the decade average.
August single-family figures show how prices differ by county. Nassau’s median closed sale price was $911,000, up about 4.7% year over year. Suffolk’s was $760,000, up about 7.0%. August inventory was approximately 2,259 homes in Nassau and 3,129 in Suffolk, according to this Long Island market report.
These numbers cover different time periods and measures: the 5,053 figure is Q3 regional listing inventory; the county inventory counts are for August and single-family homes. They should not be treated as one combined snapshot.
Why prices keep climbing
The main pressure is limited supply. When too few homes are available, buyers compete for the properties that fit their needs. That can help sustain prices even when sales activity is slower than a year earlier.
Low inventory does not mean every home will sell quickly or at any price. Condition, location, property type, and asking price still shape the result. But with listings far below the long-term average, well-prepared homes can attract serious attention.
What buyers can do now
In a thin-supply market, preparation makes it easier to act confidently:
- Get pre-approved before touring. Know your budget and have financing documents ready.
- Compare the full monthly cost. Include mortgage, taxes, insurance, maintenance, and commuting expenses, not only the asking price.
- Check the actual property-tax bill. Taxes vary by school district, town, village, and special district. Nassau buyers can look up parcel information through the county’s Land Records Viewer. Suffolk buyers can review the county’s property-tax FAQs and contact the relevant town for current bills.
- Test the commute you would actually make. Check the station, parking, transfers, and peak-hour service using the MTA LIRR timetables. Nassau and Suffolk each offer different location and commute trade-offs.
What sellers should keep in mind
Thin inventory can give sellers an advantage, but buyers still compare value. Before listing, take care of visible repairs, declutter, and present the home clearly in photos and showings. A local pricing review should account for recent nearby sales, the home’s condition, and current competition, not just record-setting headlines.
The listing calendar can matter, too. Spring often brings more choice and activity; fall can still reach motivated buyers, though the pool of listings may be smaller. The best time to sell depends on your property, plans, and local competition. Pricing and preparation matter in either season.
A practical next step
For buyers, the key is to prepare without rushing into a home that does not fit your budget or priorities. For sellers, it is to understand the value of your particular property and make a plan before going to market. A neighborhood-level assessment can help clarify the options.
