If you had a BK -you will have to wait at a minimum of 4 years with re established credit and in the price point that you will be looking at, you need a 720 credit score based on today's guidelines.
If you do a lease purchase, only a portion of the rent above "market rate" can go to the down payment.
What down payment will you give for a lease purchase?
Looking forward to hearing from you.
There are sellers who will entertain the lease/purchase certainly. Or you can lease with a "first right of refusal" clasue, which might be better for you, depending on your end goal.
I'd be happy to discuss rent/purchase options with you. I'll also take a look to see what property options there are for you.
with kind regards
