Hauppauge market
Sold homes · hamlet boundary · SuffolkA few sales here could not be placed on the map, so counts may run slightly low.
Hot Seller's MarketHauppauge recorded 118 single-family sales in the past 12 months, against 117 in the 12 months before, and 17 homes for sale now. They sold in a median of 22 days, at about 101.5% of final asking price.
The median sale price is up about 9% on the 12 months before (118 sales against 117).
That works out to about 1.7 months of single-family supply.
How we calculated this
- Single-family homes inside the official hamlet boundary (Census), Suffolk County sales only, Oct 7, 2025 – Oct 7, 2026 (the 12 months before: Oct 7, 2024 – Oct 7, 2025). For sale = listed as of Nov 6, 2026.
- Supply = homes for sale now ÷ (sales in the 12 months ÷ 12), counted the same way in each area.
- Label from the site’s scale: under 2 months Hot Seller’s, under 4 Seller’s, 4–6 Balanced, over 6–8 Buyer’s, over 8 Strong Buyer’s. A warning is added when there are fewer than 10 sales or 5 homes for sale, or one more listing or sale would change the label.
- Only homes with a map position can be placed inside a boundary. A count is shown as unavailable when fewer than 90% of an area’s sales have one (here: about 93%). A few sales here could not be placed on the map, so counts may run slightly low.
Condos: 35 sold in 12 months · 4 for sale
Only 4 homes for sale.
Hauppauge recorded 35 condo sales in the past 12 months, and 4 homes for sale now. They sold in a median of 23 days, at about 100.8% of final asking price.

The 12 months before can’t be counted inside the boundary: only about 88% of the sales in its ZIP codes have a map position, so a count inside the boundary would leave homes out.
