Most lenders require a credit score of 620+ to qualify for any mortgage. Something most people don't realize is when they check your credit, it affects it. Therefore, you need a credit score of around 625-630 to get anywhere. This is easily achieved from where you are at by paying off a credit card, or in some cases, opening a new account & increasing available credit.
I would be more than happy to help you get in touch with a lender that best fits your needs & find the home of your dreams!
