Walter,
I live, work and invest in St Joe. I was born and raised here and still need guidance on suggestions for what a rental may bring in certain parts of town. Within the last year I have realized that COC can be very positive here. We personally use Marty Lyle, owner of Top Hand, as our REI and property manager (we have 8 long terms and inherited a renter we did not want to deal with so left it with Top Hand). The others we manage ourselves. Marty is very upfront in telling you if the deal would be desirable for you. Once he learns of your expectations on property rehab, he will tell you if the deal is a match for you or not. Trust me, he's told me many times to not bite off more than we could chew.
I hate for the word to even get out about our town because I hate competition! But it's also good for the city to have investors that want to rehab and provide decent housing. So come along! message me if I can help in any way.
