Anything that does not seem to have an element of common sense. I try to stay away from. In many things today that has not proven the best course for many. So I find it pretty confusing.

I coined this era for some personal recognition as the age of illusions.

There remain things out there that are solid as a rock. Like getting into owning a decent larger apartment building in the right place. It has to be large enough to employ a good professional management service.

You refinance it every five years and put the money in your pocket. Problem is finding them as corporate arms love them. Pulling the equity every five years protects you in many ways. Almost all you need to start is a bank that trusts you. You of course use accountants and lawyers from the start. You are buying a business.

Nothing in this world is a sure thing. Yet there are many things that have relativly much higher risk factors. Rents over time tend to increase. So generally there are not too many downsides. I cannot see vacant rental space being an issue if a good choice is made.
