Renting out homes in SW Florida

[Dan Brindley]

I'm speaking specifically about the Estero area in Fort Myers. I don't live in the area but considering buying a house there and renting it out when I'm out of the country.
But I just looked on Zillow, and there seems to be A LOT of homes for rent in the area. That doesn't add up to a good place to try to rent out homes to me.
Does anyone have any inside info on the area? I'm just afraid of getting a home and not being able to find any tenants.
