FHA loans are generally the easiest to qualify for. The federal government insures these loans which means lenders can relax their qualifying rules. It’s possible for a home buyer with a credit score of 500 to get approved for an FHA loan, but most FHA lenders look for scores of 580 or better. And, a FICO score of 580 lets you make the FHA’s minimum down payment of 3.5 percent.
