if you're attempting to obtain a lease-option-to buy then it maybe a good idea of the home has equity or the neighborhood is experiencing high appreciation.
if i were in your shoes....i would rent an apartment.
it's cheaper.....you dont have to maintain a whole house...and the rental agreement can be used later to help you obtain a mortgage.
you can cut your costs from decorating a whole house...maintaining....cutting someone else's grass
if you didnt have a foreclosure...you can rebuild your credit 1yr..and buy a home with FHA with only 2.25% as a down payment.
you can buy a foreclosure for maybe 2/3 of the value...instead of paying the full price of a home..and hoping the value goes up!
