They'll micromanage the product. 

Personal excel sheet?

No signing expensive leases that you personally guarantee typically. 

As that will at least help folks that you reach out to know that you are a real person, with a picture and professional bio.

There are areas I wouldn't personally invest that I can speak to, but there are just so many opportunities.

Yea you could do it like that, but usually your lender is a broker and can find you the best products as that is their profession.

What is each person's role/superpower?

The cost to evict, in terms of lost rent, vacancy, turnover costs, plus the work involved to secure a new tenant who ON AVERAGE will be WORSE than the one you would be evicting sounds counter-productive.

House hacking will also give you some personal "property management" experience.

However, my personal opinion, is that its unethical to mark them up beyond what the consumer would pay normally.
