There are too many variables to put here. But in general terms, if your credit scores are 650 or better and your future mortgage payment (including taxes, insurance on a monthly basis) is no more than 1/3rd your take home pay, then I would say you likely can qualify for a mortgage.
The lender will then look at outstanding debt, your job/income and other factors to determine if you can get a loan. Speaking to a lender in advance of looking and knowing what price range you should be searching will help you save time and keep you from getting disappointed.
Be prepared to gather up a lot of paperwork such as your social security card, past tax returns, all of your bank statements, etc. The following is a link to several lenders that I recommend to my clients. They can assist you when the time is right.
