My wife and I only have <5 properties we are self managing.

So for a self-managed investment project, our gross profit is around $4690 a month.

But there will be fewer of them, they’ll be paid for direct client service instead of self-promotion, and there will be many fewer big earners and low earners.

I think that part is self explanatory. 

To piggyback on Jay's point, generally speaking I think the kind of personalities that are really good at real estate are the opposite of the kind of personalities that are really good at self promotion and presenting. 

Hello, 
I have a small multi-unit rental in Adams County, Colorado.  I have a tenant that is not paying rent, and won't answer phone calls or texts, so I need to start the eviction process.  The process is new to me,...

Oh, forgot to mention, this was prior to self rent rules. 

We have done 8 self storage locations and 2 country subdivisions selling lots in the Omaha area and been very successful.  

My total expense ratio on each property I own ranges anywhere from 40%-50% annually, but I also self-manage and am not a slumlord (I am pro-active with maintenance, not reactive).

Are you planning on self-managing or do you need to hire a property manager?
