NYC mortgages and property taxes, explained
Most mortgage calculators make you guess your property taxes. BlockBook looks them up: type any New York City address into the calculator and it fills in that property’s real current tax from the city’s own assessment roll, alongside its last sale price, assessed value, zoning, and full building record.
