Let me encourage you to pursue the advice given by Tony. The VA may be your best bet. His disability income will limit how much you can borrow, but if it's ongoing into the future, it can be used.
Let me discourage you on Rent to Own. It's a fantasy that leaves most who try it worse off than if they hadn't bothered. Look into the options through his credit and income and see what you can find.
If you will require both incomes, you'll need to just rent until you meet the necessary time frames to get past your BK and get established in your new town and new jobs.
The time varies, based on the type of loan you pursue. Find a great local mortgage professional where you intend to live and see what they suggest.
