I don't think it is uncommon for owners of PM companies to turn their own properties over to their business and treat them exactly the same as any client property (bookkeeping wise). 

Get some bookkeeping software like Quickbooks or the equivalent and start using it.

I like LLCs better for my passive commercial holds only, personally.My reasons for having the mgt corp were for anonymity (it has a very generic name) to pay rents to, credibility (new applicants are more ok giving my corp holding monies), having a 'bad guy' I have to check with for tenant requests, ease of p&l/bookkeeping, 1 place to receive all 1099s for HUD and agency pays, one mileage platform to record on (not every property), retirement account options, a way to obtain health insurance if needed, etc.  

You'll learn timeframes, and costs for specific items, you will learn how to deal with tenants, bookkeeping, etc.

I still want to proceed with the refi because the new loan will not only simplify my bookkeeping, it will increase my cashflow by $850'ish a month.

I've also done some research on here and throughout reddit where people hate management companies so I looked into seeing what an in-house management team would cost. 1 FT property manager = $45,000 1 FT Handyman = $40,000PT bookkeeper = $20,000Leasing an office = $15,000Paying employees insurance = ?

Proper book-keeping.

I run payroll for all my companies, I do the taxes for all my companies, I handle 80% of the book keeping as well.  

I am curious which accounting and bookkeeping packages smaller landlords prefer to use? 

She has cash and time during day, but I would do bookkeeping + set up/run BnB site + have reno skills.
