Fannie Mae, the nation’s largest supplier of home mortgage funds, has a popular program for low- and moderate-income homebuyers called Community Home Buyers. Under the program, borrowers may buy with just 3 percent down—with a 2 percent gift from family members, a government program, or nonprofit group—and obtain private mortgage insurance to protect the lender against default. The program is available through participating mortgage lenders and requires that borrowers take a home-buyer education course.
