Hi @Eric Fernwood! Great post here and a lot of healthy discussion.
You asked in your original headline "...how to stop it?"
I'm going to come at this from an entirely different angle. I just spent hours with friends who have been trying to manage single family rentals. For most people it's far more challenging to manage single family rentals than they expect. It's usually not like it is on HGTV though I admit it works out for some people.
Again to your original question, I would say most investors would be most profitable, most safe, and most happy by investing passively in commercial real estate syndications or funds. The goals are principal protection, cashflow and growth are often achieved. The operators are taking the debt in their name, finding the deals (typically off market) and they are rolling with the punches of economic cycles nationally and locally.
Though it's easy to make a mistake in this arena as well, most investors who have a job, a life and a retirement might be happier and better off investing passively. Just my two cents!
