Looking for properties to manage

Hello, I am currently managing 3 properties for 30% in northern California. I am interested in acquiring more properties. I am wondering if anyone has suggestions on how to go about it. I am also wondering if everyone has specific software or programs that they use for their management. I used to manage 1 AirBnB several years ago and recently started again, a lot has changed since then and I am hoping to pick up some tips and tricks from other property managers!
thank you

Be sure to follow the property management laws in your area. In Hawaii it is illegal to manage more than one place without a real estate license. You also have to use an on-island management company if you live off island or face fines if caught.
