I am in SW Florida,
The one thing that we do have here are some very good property management companies. The going rate is 10% per month and they pretty much handle everything as out of state landlord investors are the norm.
Rich nailed it with how hard it is to get a good deal on a property, but it's all about perspective. If you are a fix and flip guy like me then it's almost not worth it anymore here. I also moved down here 1-1/2 years ago strictly to flip homes. I have been a bit luckier than Rich as I have done about 10 homes in that time, but I probably accept a lower margin.
If you want to hold then I think good deals are still here. While rents may be stagnant, units do rent quickly and retail prices have been rising. If someone did buy homes here in the last 2 years they would have already seen their value increase.
Areas to avoid are hard to say, it depends on what you like or don't like. I don't like most of Fort Myers, North Fort Myers, or sections of Port Charlotte, but those are the most inexpensive areas. I live in Naples and it's pretty nice here.
