I can recommend several excellent lenders who can tailor a loan to your situation. With your approval, I can have them get in touch you, or provide you with their contact information. Once we have your pre-approval place, we can begin to search for a home. You're doing it right ... get your financing done first.
I assume that you realize that there's more to obtaining a loan than your FICO score. You'd likely qualify for FHA-insured financing if your debt ratio is within the established parameters, but you're going to need anywhere from 6% to 8% of the sales price in cash, to cover the down payment, closing costs and pre-paid items (insurance, HOA fees, etc.).
If I can help in any manner, please let me know. I look forward to hearing from you.
