heres my situation, how can i buy a home?

[Sam T.]

my wife and i are currently renting and paying close to 1,000 per month. our lease will be up at the end of the year. is there a way that we can buy a home creatively? we do not have good credit nor enough for a down payment.

my wife was looking through craigs last night and saw some ads about taking over payments. the person is in foreclosure and has a bunch of back payments. the owner wants to have payments taken over. what are the pros and cons to this type of situation?
another is a lease w/ purchase option that she found on craigs. rental price is set at one figure while the lease option rent price is significantly higher.
