Closed sales, September 2025 – August 2026
The East Islip market.
The figures below come from closed MLS sales, not from an automated estimate. They describe East Islip generally and put no value on any individual property.
100

Closed sales over the twelve months.
$792,500
Median sale price
Half sold for more, half for less.
18
Days to contract
From the day a home was listed to the day it went into contract.
The year in two parts
From September through February, 48 East Islip homes sold at a median of $800,000, taking a median 20 days to go into contract. From March through August, 52 sold at a median of $780,000, in 17 days.
More sales and faster sales in the second half, at a slightly lower median. East Islip is one of only three towns I pull data for where the second half prices came in below the first, and the drop here was small at about 2.5%.
I wouldn't read a direction into that. Fifty sales in a half year isn't enough to separate a market softening from a different set of houses happening to sell, and the pace picked up rather than slowed. But it's worth knowing that East Islip didn't get the spring lift most towns around here did as far as price.
Four in five sellers got their price, and the winners cleared it by $30,000
78 of the 100 sellers ended up at or above the figure they started with. House by house, the middle seller here cleared their own asking price by about $30,000, close to 4%.
That's one of the larger margins in the area. Buyers here are willing to go past the asking price for the right house, which isn't true everywhere.
The 78 who held their original price went into contract in a median 16 days. The 22 who had to reduce took 39 days and settled about 5% below where they started.
Sixteen days against thirty-nine. The reduced-price group also finished about 5% below where it started. That's a meaningful difference, even though the gap in marketing time is smaller than in several neighboring towns.
Every price range moves at the same speed
| Sale price | Homes sold | Days to contract | Got full asking price |
|---|
| Under $700,000 | 29 | 17 | 4 in 5 |
| $700,000 – $800,000 | 21 | 17 | 4 in 5 |
| Over $800,000 | 50 | 20 | 3 in 4 |
Seventeen days, seventeen days, twenty days. There's no slow end of the East Islip market. Every bracket went into contract inside three weeks and every bracket beat its asking price, by between 2% and 6%.
That's unusual and it makes this page shorter than most. In a lot of towns the useful advice is about which part of the market you're in. Here it barely matters.
Half the sales were above $800,000, so the upper half isn't a niche. Those homes took a couple of days longer and about three in four of those sellers got their price, which is still a strong result by any standard.
Search-price thresholds still matter
Buyers often set maximum search prices at round numbers, so a home just above one can miss buyers who would otherwise consider it. In this East Islip data, 92 of 158 listings were positioned just under a round number.
The $800,000 area deserves attention because it sits close to the townwide median, but positioning only helps when the underlying asking price is supported by comparable sales.
The listings that did not sell
Eleven East Islip listings ended the year without a buyer and haven't gone back on the market. That's one of the smallest groups of any town I follow, and it's far too few to take apart.
I'll give you one detail because it's striking rather than because it proves anything. Those eleven asked a median of $1,228,000 against $737,000 for the sellers who reached a closing, and they were larger houses with an extra bedroom. Eleven listings clustered at the top of the market is a curiosity, not a pattern, and I'd want a full year with more of them before saying anything firmer.
With only eleven failures, the data can't tell us why those particular homes didn't sell. Price may matter, but condition, presentation, showing access, photography and other property-specific issues can matter too. Every seller I take on gets a written cancellation guarantee.
What the market looks like right now
20 East Islip homes are on the market at a median asking price of $799,000, which sits about 1% above where sales have been closing. Another 17 are in contract.
6 of those 20 have passed 90 days without going into contract. That's close to a third of everything available, and it's among the largest stalled shares of any town I track.
Set that against a townwide 18-day median and six of 20 active listings beyond 90 days is worth attention. At that point I'd review price, condition, presentation, showing access and the rest of the listing strategy rather than assume more time alone will solve it.
So this is a market that works quickly for sellers who open at a defensible number and then does very little for the ones who don't. The good news is that the correction costs less here than in the towns on either side of it. The better news is that four in five sellers never needed to lower their price.
What none of this can tell you is what your own house would bring. Sight unseen I can only give you a range built from the closed sales. Getting to one number means standing in the house and comparing it honestly with what a buyer would be weighing it against.
One of the first houses I ever sold was in East Islip. The people I sold it to still live there.

East Islip Home Valuation
What is your East Islip home worth?
The $792,500 median describes East Islip as a whole, not your particular house. Condition, improvements, lot, location and the comparable sales a buyer would actually consider can move an individual property well above or below that number.
I prepare valuations personally using the property and relevant comparable sales rather than relying solely on an automated estimate.
