Most of the time, in today's financing environment, sellers will require to see a "pre-qualification" letter when submitting an offer to purchase a property. This shows that you have talked to a mortgage lender and at least preliminary looks like you could qualify for a loan. Without that, many people won't consider your offer. If you haven't seen a lender yet, do. Explain your situation and he/she can give you advice on when to pull your credit score again to give you the best chance of qualifying. Good luck!
