Central Islip Market Data
Current market conditions and pricing trends for Central Islip, Suffolk, NY.
Single-family, condo and co-op homes are measured separately — these medians are never blended together. Based on 218 recorded closings in ZIP 11722 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.

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 +4.9%, so most of the difference is not the market carrying the house.
What these homes resold for moved from a median of $288,000 in 2017 to $555,000 in 2024, up about 93% over the period.
The pandemic years cut against the intuition that investors moved in. Companies bought 20.3% of homes here in 2019, then 15.7% in 2020 and 12.9% in 2021 — the lowest share of the 8 years. 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 95 in 2019 to 48 in 2021.

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, 709 homes in the Central Islip school district passed between family members rather than being sold — about 26 for every 100 that sold on the open market.
73% 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 38 homes for sale in Central Islip today, 13 are now asking less than they originally asked — 34.2%, against 34.5% across Suffolk. 1 seller has raised their asking price.
And among the homes that actually sold
Among the 218 homes that sold in Central Islip over the last twelve settled months, 22.0% had cut their price before they sold — up from 19.4% 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 169 Central Islip homes that sold without ever reducing achieved 102.7% of their asking price in a median of 25 days. The 48 that did reduce achieved 96.1% of what they first asked, after 60 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 Central 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
Central Islip reads as a Seller's Market: about 2.2 months of single-family supply, and homes sold in a median of 31 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 Central 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 $600,000 — 7% above the $560,000 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 Central Islip
Central Islip is one of Suffolk's most established residential communities, offering a distinctive blend of suburban character and metropolitan accessibility. Located in the 11722 zip code, the community is served by the Central Islip Union Free School District.

Ownership here takes more than one form: condos selling at a median of $490K, single-family homes selling at a median of $606K — two genuinely different ways to live in Central Islip.

Condos are the dominant apartment form in Central Islip — deeded ownership with fewer transfer restrictions than a coop.

Schools in Central Islip, NY
Central Islip is served by the Central Islip Union Free School District. Attendance zones on Long Island are assigned street by street, so a Central Islip mailing address does not by itself determine which school a home is zoned for.
- Elementary
- Andrew T Morrow School Anthony Alfano Elementary School Cordello Avenue Elementary School Francis J O'Neill School Marguerite L Mulvey School
- Middle
- CHARLES A MULLIGAN ELEMENTARY SCHOOL Ralph Reed School
- High
- Central Islip Senior 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 247 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.
