Oh boy you are not alone. So many good people have fallen victim to the economy downturn and have not been able to meet their bills. The fact that you are working, have references and are up front about your situation is a plus in your corner.
Good luck with your rental. You might want to speak with a good company who does credit repair? Just a suggestion. I'm not sure what type of credit problems you had, but be careful with that also as not all of these companies are on the up and up. Ask around for referral from friends and family if they have used one of these companies.
