Compared to buying a similar unit in this neighbourhood.
How is this calculated?+
Estimated monthly carry is the building's average rent multiplied by 1.37x — a rough heuristic for what an equivalent purchase would cost per month. The 1.37 figure approximates principal + interest on a 20% down loan at 6-7% mortgage rates, plus typical NYC property taxes, homeowner insurance, and maintenance reserves.
Annual savings is the difference between this estimated monthly carry and the building's average rent, multiplied by 12.
This is an approximation, not a per-building mortgage calculation. A full rent-vs-buy calculator with explicit inputs (down payment, rate, taxes, appreciation) is on the roadmap. See accuracy disclaimer.
