Hi, Ann!
OK, when obtaining a mortgage, the underwriter is going to look at this trio of factors: 1. Your income 2. Your downpayment 3. Your credit score. It sounds like your income is good. They will want to make sure it's stable, so they will verify your employment. If you have money saved up for your downpayment, you're in good shape. If not, you can obtain that as a gift, so you don't have to have it in your own funds. In the event of a gift, you will have to get a letter from the giver stating they are GIVING the money to you and you don't have to pay it back.
Now, your credit score. That's going to be a problem. You need to take a good hard look at those things and get on a plan to improve it or, in this market, your shot at getting a mortgage is going to be slim or none. Take a look at this article to find out more about how to get on a good plan for cleaning up your credit.
