I've actually been in the commercial property management business for a while. I can assure you that the notion that you can charge whatever rent you like is false. That it's a magical money machine is false. That you don't have large and ever-growing expenses is false. That landlords don't go bust is false. That you make money with an unrented property is false. That there is some secret cabal of landlords is false.

I lost money every year in it, and finally gave it up before it crushed me.

Sure, I stink as a businessman. But that's also my point. It ain't an easy business to make money in.
