The house you are looking at was built in 2006, so there may be a issue with Chinese Drywall. Lehigh Acres may not bring the rent you are looking for as compare to properties in Fort Myers and the Cape.
If you send me a list what you are looking for, and how much is your comfort zone is, I will send you a list of properties you may buy and rent out for a good return.

Good luck in your searching.
