How to grow/scale up?

[Robert Carl]

Im trying to grow my rental business. My question is how to move to the next level. My first goal is to have my properties operating with 2 full time maintenance men and 2 managers when I hit 20 rentals. Is it better to hire in house or from a management company?

I want to scale up where I can just check the financials. How do you scale up? Currently at three and renovating number 4. Have a couple others to start also.
