What really drives the timing decision
After more than 25 years selling across Upper Manhattan, Queens, and beyond, I have learned that the "should I sell now" question is rarely about predicting the market. It comes down to a handful of personal factors. The biggest one in this cycle is the rate lock-in effect: if you are sitting on a mortgage below 4%, selling means giving that up and buying your next home at today’s rates, which quietly raises your real cost of moving. If you have a clear reason to move, that matters less. If you are only chasing the top of the market, it matters a lot.
The capital-gains clock
If the home is your primary residence and you have owned and lived in it for at least two of the last five years, you can typically exclude up to $250,000 of gain if single, or $500,000 if married filing jointly. Selling before the two-year mark can forfeit that exclusion and expose you to short-term gains. Confirm your specifics with a tax advisor, but the two-year line is worth knowing before you list.
The other levers are your equity (thin equity gets eaten by selling costs), a co-op flip tax on a short hold, your timeline flexibility, and whether the home is ready to show. The tool above turns those into a clear lean. When you are ready for the number that anchors the whole decision, get a free comparative market analysis, then see what you would keep with the net proceeds calculator and how I market a home on the sell your NYC property page.
If you own a 2-to-4 family building
Switch the tool to building mode and the honest test becomes the cap rate on your number: net operating income divided by what you believe the building is worth. If it earns under 4% on that value, a buyer is paying you for the price, not the income, and holding mostly means carrying a thin return. Above 6%, the income is pulling its weight, and a 1031 exchange can move it into another property instead of cashing out. Those cutoffs are this tool’s rule of thumb, not a market fact. Deferred maintenance and open violations come off the price either way, as a repair you pay for or a discount a buyer takes. For the full decision, read owned a 2-to-4 family for 30 years: sell, hold, or exchange, and check the tax side in the capital gains guide.
