ONE+Boston Homebuyer Program

This mortgage program provides low interest mortgages to qualified Boston homebuyers.

ONE+Boston offers the lowest fixed interest rates available for a 30-year mortgage. Additionally, it provides access to downpayment and closing-cost assistance. The City wants to increase the buying power of income-eligible, first-time homebuyers purchasing a home within the city of Boston.

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.
