It seems like real estate all over the world is overpriced at the moment. All the good stuff has been bought. Lots of investors do it for prestige than money. There's also been a rise in people wanting 'passive income' and somehow thinking that houses are the easiest way for it.
Not saying you can't make money off it, but it feels like the odds are you'd lose money if you don't know what you're doing, and you'll put it into something that's not liquid.
