Over the last three years the median sale price in Barnum Island, NY rose 68.9%, from $642,500 to $1.08M. 20.0% of Barnum Island listings cut their asking price in the final Redfin month — a modest share, which is what a market looks like when sellers are pricing close to where homes actually clear. For prices to fall meaningfully from here, supply would have to keep building past 2.5 months while the sale-to-list ratio slips below its current 97.1%. Watch those two together — they move before the median does.

Priced off the median sale price of $1.08M at the current 7.03% 30-year fixed rate. These are principal and interest only — property taxes, homeowner's insurance, HOA dues and mortgage insurance are on top, and they vary enough by property that we will not guess them for you.

Redfin, through May 2026 for the price · Freddie Mac via FRED, September 2026 for the rate
Lenders generally want housing costs under 28% of gross income. On the 20%-down payment of $5,792, that implies roughly $248,242 a year before you add taxes and insurance. The median household in Barnum Island earns $118,160, about $130,082 short of that threshold — the typical local household needs a larger down payment, a co-borrower, or a home below the median sale price to fit the 28% rule. That puts the price-to-income ratio at 9.2x — well above the 3x that was historically considered affordable, which is why down payment size drives who can buy here.

Zillow does not publish a rent index (ZORI) for Barnum Island, NY, so we cannot compute a price-to-rent ratio here without borrowing a nearby market's rents and calling them local — which we will not do. The rent vs. buy calculator works with a rent figure you supply.
Active listings in Barnum Island, NY went from 6 in March 2025 to 5 in May 2026, a -16.7% change. Falling inventory tightens competition. When supply drops while demand holds, sale-to-list ratios rise before the median sale price does.
