I know I’m going to make mistakes, but I would like to minimize those mistakes as much as possible by finding a mentor.

I assume this helps provide some filtering of those serious and those who aren't plus some minimal income that helps offset the assessment time involved also. 

Call the police where she is located and ask for help, also the attorney general's office.You need to directly speak with every single one of your tenants today and notify them verbally, and in writing, that they are not to pay the property manager this month, or you will lose June's rent, also.Surely she has a drug, alcohol, or gambling problem, and has simply taken your money. 

I expect to use the income from flips to grow my landlord portfolio but I realize I am about to generate taxes at a new and frightening pace and want to make sure I minimize the liability as much as legally possible by being set up correctly and using the right accounting software that will allow me to track multiple flips at the same time and account for rental income.

There's always going to be ebbs & flows, but over time Self Storage has almost always come out better than most of the other assets.And yes, like many others are saying here, we are experiencing some of the better months than we've ever seen, but of course a lot of our customers and fellow Americans are all hopped up on free government money which was intended to minimize the disruption of normal economic activity.
