Property management book suggestion

[Sarah Huynh]

Hello Everyone, just wondering if anyone have any suggestions on a good beginner book for managing a commercial real estate? I own a 3 units commercial building and currently hire a management company, but they are charging me so high. I am looking to start managing on my own in a few months. I work as a nurse and have no experience in managing a commercial building. Any suggestions and inputs on how to start is greatly appreciated
