NEW YORK (S&P Global Ratings) Oct. 13, 2022--S&P Global Ratings raised its long-term rating and underlying rating (SPUR) to 'AA+' from 'AA' on bonds outstanding under Massachusetts Housing Finance Agency's (MassHousing) housing bond resolution. At the same time, we assigned our 'AA+' rating to MassHousing's 2022 series C housing bonds. The outlook is stable. "The rating upgrade reflects our assessment of the strong presence of federal insurance and tax credits on more than 80% of the loan portfolio, in addition to the relatively conservative debt profile and strong management team," said S&P Global Ratings credit analyst David Greenblatt. The rating reflects the application of our "Methodology For Rating U.S. Public Finance Mortgage Revenue Bond Programs," published Oct. 10, 2022. We
