If it's credit related I have a credit guy but my Lenders offer FHA loans that require a 580 score, Conventional require a 620 so usually credit is not an issue. I can refer you to an agent to help you find a home and a Lender or two that can get you pre approved.
Add them to my database and let them know that I'll be ready to help them find a great home as soon as they're ready to buy one. Then I'll have them consult with a knowledgeable lender to help them get on track to get the issues corrected.
I generally ask them to talk to a couple of my favorite local lenders so that they understand their options and what they need to do to eventually qualify for a loan. I advise them to wait a while and work on savings and credit improvement. Also, I'm a big financial geek, so I've offered to help people with a budget before. The last thing I want is a client of mine not being able to make their payments after they purchase.
