My CPA says it is sufficient for tax purposes to have records of invoices from the PM to me. 

I'll have to figure out how to just finish my taxes for 2020, and see what ratio the CPA says and then follow up with the Assessor.

Talk to a CPA.

Did you have people like a real estate agent, contractors, bookkeepers, a CPA, and all of those other roles already on your "team" or did you just purchase the first property and find people for those roles as you went?

Do you recommend a CPA to handle all things on the books, or should your property manager be doing ALL of this?

You'll need to get a good investor friendly CPA, possibly an LLC, bookkeeper, umbrella insurance coverage, separate bank account for rental. 

Attorney or CPA?

Using stessa, i can even click a button and export my end of year income/expenses for my CPA! 

You should also connect with a tax planner/CPA regarding the pros and cons of having an LLC vs trust vs individual.

I use John Rosenbohm CPA 309-565-8268.
