How to start my own Property Management Business

[Jeffrey Smith]

Hello! im new here, my names Hunter and I come with two short term rentals and two long term rentals. Id love some input on starting my own property management business to generate cash for more deals. I already manage all of my own rentals with my fiance but im more unsure of the financial part of managing others. I do have an LLC, and have always done my own taxes, but never official book keeping. Any help or advice would be great!
