There are literally thousand of timeshares in Florida, especially Orlando. Off-season rentals would be possible, but check on the various TS rental sites to see what the "going rate" is. You have to be sure that the rentals are greater than your annual MFs.
I normally wouldn't buy a TS for rental purposes unless it is a high demand resort/week Florida keys in the summer or during Fantasy Fest).
My guess is that most of these "deals" are from PCCs or people looking to dump their TS because they CANNOT rent or sell them, but I'm sre there are others who disagree.
