Buying a property management company a good idea?

[Lowden Charles]

Hi all! 
I’m a real estate investor who has decided to get my license (based in NY) and would like to buy a property management company in the Westchester area. We self manage our own properties (5 properties with 8 doors) and love it. Wanted to know if anyone had advice or experience purchasing a property management company so we can come with a book of business or if that’s even a good idea to look into. 

Any help is welcome!
