Centerport Market Data
Current market conditions and pricing trends for Centerport, Suffolk, NY.
Single-family, condo and co-op homes are measured separately — these medians are never blended together. Based on 71 recorded closings in ZIP 11721 between Sep 10, 2025 and Sep 10, 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.
Momentum in 11721 has been building over the past 2 years — the median sale price has climbed roughly 38% year over year to about $1.2M while time on market has generally shortened. That combination points to conditions favoring sellers — and if it continues, further firming is possible.

Across 8 years of county-clerk records, 93 homes in the Harborfields school district were bought by a company and resold within two years. Over the whole period the typical one was bought for $404,774 and resold for $659,000, a median of 8.5 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 +6.1%, so most of the difference is not the market carrying the house.
What these homes resold for moved from a median of $585,000 in 2017 to $735,000 in 2024, up about 26% over the period.
The pandemic years cut against the intuition that investors moved in. Companies bought 7.8% of homes here in 2019, then 5.4% in 2020 and 5.4% in 2021 — the lowest share of the 8 years. In the two years when buyers competed hardest, companies won a smaller share, not a larger one. The number bought and resold within two years fell with it, from 10 in 2019 to 8 in 2021.
Since then it has reversed. Company buying reached 10.7% in 2024, the highest of the period — above its pre-pandemic level, while the market cooled.

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, 322 homes in the Harborfields school district passed between family members rather than being sold — about 16 for every 100 that sold on the open market.
83% 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 11 homes for sale in Centerport today, 3 are now asking less than they originally asked — 27.3%, against 34.9% across Suffolk.
And among the homes that actually sold
Among the 72 homes that sold in Centerport over the last twelve settled months, 20.8% had cut their price before they sold — down from 23.6% over the same twelve months a year earlier.
What each group got
Over those same twelve months, the 57 Centerport homes that sold without ever reducing achieved 102.0% of their asking price in a median of 20 days. The 15 that did reduce achieved 88.8% of what they first asked, after 67 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 Centerport 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
Centerport reads as a Seller's Market: about 2.2 months of single-family supply, and homes sold in a median of 24 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 Centerport 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.
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.
