in Perspective
Purchasing residential real estate in New York City and the surrounding Tri-State suburbs requires modeling transaction taxes and recurring property levies that differ sharply from national averages. Within the five boroughs, buyers of properties priced at $1,000,000 or more pay New York State's progressive Mansion Tax, which scales across eight statutory brackets from 1.00% ($1M–$1.99M) up to 3.90% ($25M+). Furthermore, financing a Condominium or Townhouse triggers the combined NYS and NYC Mortgage Recording Tax (MRT) of 1.80% on loans below $500,000 and 1.925% on loans of $500,000 or more—a tax from which Cooperative (Co-op) apartments are legally exempt because co-op shares are classified as personalty rather than real property.
Outside NYC, effective property tax rates in Nassau, Suffolk, Westchester, Bergen, Essex, and Fairfield counties routinely range from 1.85% to 2.35% of market value, adding $1,500 to $2,500+ per month to a standard 30-year fixed mortgage payment tracked by Freddie Mac PMMS.
