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.

I knew that if I could live off side hustle bookkeeping income, have a $0/month rent payment, and save an entire year of public accounting salary that I would be set to start my own businesses and invest in more real estate.

You hold your lawyer, accountant/bookkeeper, banker, grocer, etc. accountable, as do I.

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