If you look at the last centuries, property was the best form of investment and that is not going to change in the next few centuries either. Why? Are we getting more or less people on this planet? And do pretty much almost all of them need a place to stay? So there will always be demand.
Of course how good of a potential a property investment is, depends on the country and location. But when selecting the right one, I believe property has been, currently is, and always will be a good investment and has a bright future.
