How often co-op, condo and house listings ended without selling, what each sold for, and how long it took — county by county, from MLS data.
“Did not sell” is the share of listings that expired or were withdrawn, October 2025 to September 2026. Prices and days on market are the last 12 months of sales.

Not by how often listings sell, in our MLS data for October 2025 to September 2026. In Nassau, 22% of co-op listings and 21% of condo listings ended without selling, against 24% of house listings — condos failed to sell about as often as co-ops. In Suffolk, 19% of co-op listings and 15% of condo listings ended without selling, against 23% of house listings — condos failed to sell about as often as co-ops. In Queens, 39% of co-op listings and 59% of condo listings ended without selling, against 37% of house listings — condos failed to sell more often than co-ops. Median days on market (September 2025 to September 2026): Nassau 37 days for co-ops and 28 for condos; Suffolk 29 days for co-ops and 29 for condos; Queens 64 days for co-ops and 61 for condos. Co-ops did take longer to sell in Nassau (37 days against 28). The MLS does not record why a co-op sale fell through, so these figures cannot show how many deals ended at board approval.
Yes, in all three counties we track. Median sold prices, September 2025 to September 2026: Nassau co-ops $365K against condos $785K; Suffolk co-ops $277K against condos $525K; Queens co-ops $335K against condos $626K. A co-op's monthly maintenance usually includes its share of the building's property taxes, so compare monthly costs as well as prices.
Measured on listings that ended October 2025 to September 2026: in Nassau co-ops failed to sell about as often as houses (22% against 24%); in Suffolk co-ops failed to sell less often than houses (19% against 23%); in Queens co-ops failed to sell about as often as houses (39% against 37%).
A condo buyer receives a deed to the unit. A co-op buyer receives shares in the corporation that owns the building and a proprietary lease for the apartment, and the purchase needs the approval of the co-op's board.
Did not sell is the share of listings that ended between October 2025 to September 2026 by expiring, being canceled or being withdrawn, out of all listings that ended that way or sold in the same months. They are listing attempts, not homes: a home relisted in the year counts again. Listings taken off the market only temporarily are left out. Fewer than 20 listings in a cell and it is not shown.
A difference between two types is described as one only when it is statistically clear (a two-proportion test); otherwise the page says they fail to sell about as often. Each county is compared only with itself, because co-ops cluster in Queens, where every type fails to sell more often, and a combined figure would blame the co-op for the county.
Median sold price and days on market are the trailing-12-month figures from each county's market report (September 2025 to September 2026). Houses means single-family homes.
The MLS does not record board rejections, so nothing here measures how often a co-op board turns a buyer down. Brooklyn is not included.
Figures are county-wide medians drawn from live OneKey MLS data and refresh as new sales close; they describe the market, not any specific property, and are rounded to avoid false precision.

Co-op, condo and single-family figures are kept separate and each county is compared only with itself.
