Depends on where you plan to invest. For example I have a friend who bought property in Thailand https://tranio.com/thailand/ just because it is much cheaper there and started to rent it out on popular websites like booking and so on. From renting it for several days or weeks he gets much more money in compare if he is renting it for long term. Good thing about Thailand is that tourists go there all years around even when it is a winter season if I may call it like this. Did you think about this country?
