Four New Hampshire affordable housing projects with a total of 133 units have been awarded a combined $6.7 million in grants and loans by the Federal Home Loan Bank of Boston.

The support, awarded to four New Hampshire banks through the FHLB’s Affordable Housing Program, is part of $46.6 million in funding given to 47 projects with 2,550 units around New England.

The grants and loans will be used to help pay construction, acquisition and rehabilitation costs. Member banks work with local developers to apply for funding, which is awarded through a competitive scoring process.
