Currently I'm investigating Danny Johnson's REIMobile since I'd already have to pay a perpetual fee for use.

I see stereotyped ideations of wholesalers with no regard to those who are doing it right.

By perpetuating the social stigma of being a "felon"; denying access to employment, denying access to housing..you do nothing but encourage recidivism..and continue the vicious cycle..which is exactly what your government and for-profit prison industrial complex wants. - A productive member of society who was once a court date away from being a convicted felon. 

Maybe after attending the funeral of the 10 year old kid who lives in the building, you might decide to not live in perpetual fear and prejudice and take some action.This business is NOT for everyone.

I have no clue why not I guess they see a transaction as a perpetual cash register versus being an investor might seem risky to them.

In general, how does a landlord take over a unit if they want it back other than evicting once it becomes a month-to-month lease in perpetuity?

They know the ones who provide good value and those that don't.Survey and title work hiccups:  Realtors often fall victim to the "they just want their commission check" stereotype. 

I suppose implicitly that may be the case since cap rates are essentially discount rates of perpetual NOI and higher rates would imply more risk, but it seems like you're being sloppy with terms.

This is especially confusing since Cap Rate is implicitly a cash flow measure (perpetuity of the NOI), and since closing costs would be paid as an initial outlay (ie part of that cash flow).

If you want to scale, in a way that is not dependent on you doing work, you need to invest in assets like real estate, or people and systems that can operate and generate income in perpetuity.
