I'm sure there's good deals left in Destin. You'll just want to do your research. On the plus side, Destin's city council voted last year to allow short-term rentals throughout the city. That means there more investment properties (condos especially) and a greater volume of visitors. Good conditions for buying investment property, I would think.
Look through our Real Estate listings for realtors and condos that can help you further.
I'm sure there are others out there with more experience who can give mobetta better advice in this than I can... any takers?
