My opinion is just of an amateur, but I think way too many wealthy people are learning that it is way safer AND lucrative to use their wealth to buy property to "rent" out or to flip. It IS VERY safe and lucrative than investing in some venture or a business.

As more and more wealth flows into this type of venture, whoever wins the bidding war for a property has to charge higher rent to somehow recoup the investment they made to buy the property AND make profit on top of it.

And of course there aren't THAT many small businesses that can pay that kind of rent.
