I have a direct lender with inhouse financing that will finance FHA with 620 score.
I just helped two buyers that were seeking help on Trulia with the same scores as yours and they were both approved for FHA loans with vey low interest rates and bought houses.
For more information call me at 702-612-7099
As far as the Fico score goes it varies from lender to lender and even more so if your dealing directly with a Bank like Bank of America or Wells Fargo.
Most lenders go off your middle Fico score, and there are other factors to consider on your credit. Like if you have any collections or derogatory credit issues. You may need a 620 fico score for a FHA loan.
I have a lender that helps me and my clients that have a little harder time getting qualified. Contact me if your interested? We can get started right away.
