"Desperate," do you have any money you could put down?
I work with a team of investors who have several properties in the San Antonio area available for lease with the option to buy.
Your credit isn't as important as your ability to pay a small chunk down - usu b/w $2k-$5k, and that money can go toward the purchase of the property if you decide you want to own the house.
We even have a credit-repair process that gets you going in the right direction so you are more likely to get financing a year or two down the line.
Let me know if you're interested and we can see if any of the lease-option properties look good to you!
Either way, good luck and I wish you the best!! :D
