Multilingual Information about ONE+Boston

ONE+Boston will provide these benefits:

  • Heavily discounted, fixed, 30-year interest rates
  • Enhanced down-payment assistance through the City of Boston
  • No private mortgage insurance (PMI)
  • Additional financial assistance, for eligible buyers

To get a ONE+Boston mortgage you must:

  • Be a current resident of the City of Boston. You will be asked to provide a copy of your current lease OR current utility bill OR voter registration
  • Be a first-time homebuyer. This means that you have not owned a home at any point in the last three years.
  • Take a homebuyer class. This class will help you get ready for the home buying process.
  • Meet our down payment requirements. We require a 3% down payment to buy a condo, single-family home, or two-family home. At least 1.5% of the purchase price must be from your own savings. For a three-family property, we require a 5% down payment with at least 3% from your own savings. The City of Boston is providing enhanced down payment assistance as part of this program.
  • Have a total household income under our limits.
