Try an apartment complex, i.e. Arbors at Branch Creek near Hillsborough and Countryway Blvd.
Otherwise you'll need to verify the owner is not in foreclosure and is actually the owner.
There isn't much financial incentive for agents to assist with rental properties so you may have to go it alone. I've seen as little as $35 offered on a rental listing and that wouldn't pay for a Realtor's gas for her car!
Since you mention you have good credit, you may be able to get up to $10k to buy a home from the State of Florida Bond program. There is plenty of money available but you need to work with an approved lender to get the money.
All the best,
