Market snapshot
Recent data show the median sale price at just under $2.0M in January 2026. While that represents a year-over-year dip, sale-to-list ratios remain strong at about 97.6%, and 50% of homes sold above asking. The area is still considered very competitive, with some properties drawing multiple offers.
Inventory remains tight. In January, four homes closed, down from six a year earlier. Across Greenwich neighborhoods that include Cos Cob, market conditions have continued to favor sellers, though average days on market have ticked up compared to last year.
Rentals and financing
On the rental side, Fairfield County communities continue to see firm demand heading into spring leasing season, according to recent rental market updates. For buyers watching rates, several Connecticut lenders are advertising 30-year fixed mortgages in the mid-5% range as of March 2026, a notable shift from the sub-3% era but relatively stable compared with late 2025.
What this means locally
For sellers, realistic pricing is key as buyers show more sensitivity to days on market. For buyers, slightly longer marketing times may create negotiation room, especially on homes that need updates.
Home projects remain part of the equation in this price tier. Local ServiceXTC providers serving Cos Cob include: Pillar To Post Home Inspectors – Home Inspector; Emerald Roofing and Siding – Roofer; and Ruane Construction – Remodeling and Home Builder.
