above is a link to 18 "rentals" $800 or less.
Just be very careful if you decide to rent from an individual owner because many are in preforeclosure status and you may have to allow Realtors to Show to prospective short sale buyers. It's not fun having strangers trapse through... Also a distressed owner may not return your deposit money or not have money to make needed repairs.
It may be less risky to rent in a complex until you are in a position to be an owner.
If you have verifiable income and sufficient credit score (620 minimum) and are a first time homebuyer, you may be able to get up to $7,500 from the State of Florida bond program to become an "owner":
If your credit history or score is preventing you from getting a mortgage, you might also try a credit union NACA:
Just make sure to select your Realtor and have her sign you up on the NACA website or she'll have to pay NACA a large "referral" fee.
All the best,
