Common questions

What is included in a monthly mortgage payment?

Principal and interest on the loan, plus usually property tax and homeowners insurance (often paid through escrow). Condos add common charges; co-ops add maintenance, which already includes the building’s taxes.

How much down payment do I need in NYC?

Conventional loans allow as little as 3–5% down, but many NYC co-op boards require 20% or more. Under 20% down usually adds private mortgage insurance (PMI).
