Islip Market Data
Current market conditions and pricing trends for Islip, Suffolk, NY.
Single-family, condo and co-op homes are measured separately — these medians are never blended together. Based on 142 recorded closings in ZIP 11751 between Sep 17, 2025 and Sep 17, 2026 — a settled trailing twelve months, ending about a month back so late-recorded closings are counted rather than missed. Days on market are medians, not averages. A property type with fewer than 8 closed sales in that window is left out rather than published on a sample too thin to mean anything.
Single-family prices in the Islip Union Free School District are up about 7% year over year, comparing 125 sales in the 12 months to October 3, 2026 with 132 in the 12 months to October 8, 2025. Over the past 2 years, single-family monthly median sale prices in ZIP 11751 have ranged from $620K to $868K.

Across 8 years of county-clerk records, 113 homes in the Islip school district were bought by a company and resold within two years. Over the whole period the typical one was bought for $270,000 and resold for $440,000, a median of 7.2 months later.
That difference is gross. Renovation, carrying, financing and selling costs are not recorded anywhere public, so it is the change in price, not a profit. Over a hold of that length prices across the county moved about +5.2%, so most of the difference is not the market carrying the house.
What these homes resold for moved from a median of $340,000 in 2017 to $675,000 in 2024, up about 99% over the period.
The pandemic years cut against the intuition that investors moved in. Companies bought 14.5% of homes here in 2019, then 8.2% in 2020 and 10.9% in 2021. In those two years companies won a smaller share, not a larger one. The number bought and resold within two years fell with it, from 21 in 2019 to 13 in 2021.
Since then it has reversed. Company buying reached 14.5% in 2024, the highest of the period — around its 2019 level of 14.5%.

That difference is gross. Renovation, carrying, financing and selling costs are not recorded anywhere public, so it is the change in price, not a profit.

Source: property transfers recorded with the county clerk, which cover every sale rather than only those listed for sale. Filings reach the state months after closing, so these figures run to October 2025 and describe what has already happened rather than the market today.
Between 2017 and October 2025, 398 homes in the Islip school district passed between family members rather than being sold — about 29 for every 100 that sold on the open market.
69% of them recorded no price at all, so they appear in no market statistic, no listing history and no sold comparable. They are counted here because the transfer itself is filed with the county clerk, whether or not money changed hands.
Counted from the reason recorded on each transfer with the county clerk, not from the price. Transfers filed only to add or remove a name on the deed are excluded — those are paperwork, not a change of owner. Where a filing gives no reason it is not counted, so these are minimum counts rather than a complete rate, and they run to October 2025.
Of the 28 homes for sale in Islip today, 11 are now asking less than they originally asked — 39.3%, against 34.5% across Suffolk. 1 seller has raised their asking price.
And among the homes that actually sold
Among the 148 homes that sold in Islip over the last twelve settled months, 22.3% had cut their price before they sold — up from 10.2% over the same twelve months a year earlier. The for-sale figure runs higher than the sold figure because homes that need a reduction stay on the market longer, so they build up among the listings still available while the completed sales are led by homes that sold without cutting.
What each group got
Over those same twelve months, the 115 Islip homes that sold without ever reducing achieved 102.6% of their asking price in a median of 19 days. The 33 that did reduce achieved 90.5% of what they first asked, after 90 days.
Homes that never reduced and homes that did are different homes, priced differently from the start — these figures describe what each group did, not what a reduction causes. How any individual home performs depends on condition, layout, its position within Islip and how it shows, none of which a market median can capture.
Measured from the OneKey MLS feed, updated daily. A home counts as reduced when its current asking price is below the price it was first listed at — not against an estimate or against other homes. The for-sale figures describe homes available today; the sold figures describe closed sales between September 2025 and August 2026.
What This Means for Sellers
Islip reads as a Hot Seller's Market: about 1.6 months of single-family supply, and homes sold in a median of 23 days over the past 12 months. If you're considering selling, this market rewards strategic pricing — not overpricing. A properly positioned listing will attract qualified buyers and maximize your net proceeds.
What This Means for Buyers
Buyers in Islip should be prepared to act quickly and come with strong offers. Pre-approval is essential, and buyers are generally better served retaining their own real estate attorney early to review the negotiation and contract. Expect competition, but don't overpay — there's a difference between being competitive and being reckless.

The listings that did not sell asked a median of $679,000 — 4% above the $650,000 median of the homes that closed. Counted over the trailing twelve months: every listing that closed, expired, was withdrawn or was terminated. Listings still active or under contract are not counted on either side. If the feed does not retain every withdrawn listing, the real figure is higher than the one shown, never lower.

What It's Like Living in Islip
Islip is one of Suffolk's most established residential communities, offering a distinctive blend of suburban character and metropolitan accessibility. Located in the 11751 zip code, the community is served by the Islip Union Free School District.
With a median home price of $718,000 and a median recorded property tax of $14,000 annually, Islip pairs an established housing stock with direct access to New York City. The commute to Manhattan averages approximately 74 min via the Long Island Rail Road.
Ownership here takes more than one form: coops selling at a median of $275K, single-family homes selling at a median of $718K — two genuinely different ways to live in Islip. In a coop or condo, the building handles the envelope — roof, heat, grounds — and your monthly maintenance or common charges fund it; in a house, those responsibilities (and that flexibility) are entirely yours. Coops are the dominant apartment form in Islip — board approval and building-set financial requirements are part of most apartment purchases here.

The bill funds school-district, county, town, and special-district services.

Schools in Islip, NY
Islip is served by the Islip Union Free School District. Attendance zones on Long Island are assigned street by street, so an Islip mailing address does not by itself determine which school a home is zoned for.
- Elementary
- Commack Road Elementary School Maud S Sherwood Elementary School Wing Elementary School
- Middle
- Islip Middle School
- High
- Islip High School
These are the schools recorded on homes sold in this district over the last 12 months — the district may also serve neighbouring communities. Zones can change and run street by street — we confirm the exact assignment for any home before you offer.
Typical value is the median recorded sale price in the district. Typical annual tax and effective rate are the median recorded tax bill and that bill divided by the median sale price, across 129 recent sales carrying a reported tax figure — an observed cost ratio, not an official millage rate. District boundaries can cross town and postal lines, so always verify the district for a specific address.
