I've not heard this idea for a year or so...I blame TV shows on moving to the sun myself....

I think a lot of the hard working villa owners here will tell you its hard enough running your villa on the money you get from rentals...let alone trying to live on it too...
You could do a lot more with $800k ....if I had that kind of money spare the last thing I would do is buy rental homes with it in FL anyway...you could buy a good business....and still have money in the bank...you really need to look into this a lot more...its not easy...
