As some banks veer away from Federal Housing Administration loans, they’re offering their own low down payment mortgages to appeal to home buyers struggling to save enough to buy a home. Wells Fargo lead the way last week with the debut of its 3 percent down payment loan. JP Morgan Chase also is offering a 3 percent down payment program for buyers with a FICO score of at least 680. Other banks are following suit with their own low down payment loan programs.
