I bought a property in Florida about 3 years ago and don't really have too many complaints. It's gone down a bit but man is it nice, right on the gulf of Mexico nothing between us and the beach. I also have clients who have bought in the US for various reasons, and personally i think if you do your homework it's a pretty good investment. Focus on the cap rate (net rent/purchase price) and location and you'll likely do fine over the long term. Regardless of where the market is today, the demographics still aren't going to change and if own a property in a very desirable area in an upscale location you should do okay. One person I know bought herself a condo for under 70K a few years ago and she's been happy with it. I'd probably avoid forclosures and shortsales are a hassle, but since they influence the market there's no particular reason why you can't get something at a similar price without the hassle or worry.
Financing can be a bitch but I think things are improving. I've gone through hoops several times once to purchase and once to try and acquire a LOC and it's a lot of hoop jumping, us being US Alien's and all. I did qualifity for one loan but I turned it down cause I could get financing cheaper here than in the US.
