I'm not sure. European house prices are much more realistic than American, and Europe doesn't have the same baby boom pattern as the US.
Not every country looking at 50 million houses going on the market in the next 20 years.
I can't confidently say whether I would or would not, but if I would then it wouldn't be for the same reasons as why I would in the US.
BTW: When I said El Salvador property, my main thinking was that it should be cheap enough that if all else fails, you CAN walk away from it.
