Normally, one month on the job is enough, unless there was a gap before this job. Then, you will need to establish a longer employment history. Bad credit is fixable. If you go to see some good mortgage professionals, they will tell you how to fix your credit, but it might take time and perseverance. You'll also need to budget for things that come with buying your home: downpayment, closing costs, home insurance premium, inspections, etc.
But, think about it this way - it will be worth it!
