There are a few things to consider. A big one is finance:
1. How comfortable are you in making x payments for x years at 8%?
2. Will there be a promissory note?
3. Any liens as a condition?
4. Down payment?
5. Is the money being asked eating at your reserves?
Even if you had filed bankruptcy 4 years ago, depending on the reason for filing and whether it has been discharged, lenders might consider lending to you.
Gifting/granting agencies could also help as long as the seller is interested in participating in the program.
You might want to involve a real estate agent who has sufficient background in real estate laws and lending. Maybe even seek the advice of an attorney to evaluate this for you.
