ONE+Boston Homebuyer Program

The City of Boston is introducing a new homebuyer program, ONE+Boston.

ONE+Boston will offer the lowest fixed interest rates available for a 30-year mortgage. It will also provides access to downpayment and closing-cost assistance. We want to increase the buying power of income-eligible, first-time Boston homebuyers purchasing a home within the City. Our goal is to help fulfill Mayor Walsh’s pledge to create 1,000 new homeowners by the end of 2023.  

What is ONE+Boston?

A mortgage with a heavily discounted fixed interest rate

Using funds provided by the City of Boston, the ONE+Boston interest rates are 0.5% to 1% below the already discounted ONE Mortgage rates.

Includes enhanced downpayment assistance

For those first-time homebuyers who qualify, the City of Boston’s financial assistance will offer enhanced downpayment and closing cost assistance.
