The Public Project Revolving Fund (PPRF) is NMFA’s flagship program. The PPRF is used to finance public projects such as water system upgrades and other infrastructure improvements, fire and law enforcement equipment, and public buildings. Both market rate based loans and loans to disadvantaged communities at subsidized rates are made from PPRF funds.
