Are there any lenders still doing FHA loans with a middle score of 626?

I live in SC and trying to buy a house before the end of the year and have worked so hard on my credit for over a year and still trying to "build" it up. But now I am finding that most lenders have raised the limit for the credit score to 640. I'm trying to see if there are any lenders still approving for 620, but at a good rate?
