Have you looked at the opportunity for dual enrollment ( state pays for high school students to take college classes). 

Learn enough so I can provide free classes to low income and Spanish speaking communities on how to get into real estate investing.

I do have some experience with c class neighborhoods and rentals but they were all within an hour drive and we were very hands on both in property management and maintenance.

You have to tell it what category the expense is and what "class".

No particular price, asset class, or market to eliminate yet but that's coming soon enough. 

I'm looking for cashflow, C class or better, multifamily would be great.

I provide that, plus a place to cook and do laundry in an environment that looks like Hugh Hefner decorated it.

But it seems this is a more conservative approach/more passive option which would be feasible while working full time.Another option I have been looking into is getting back into rentals (Class B). 

You might have decent odds if you are buying almost new class A in an A location but then cash flow can be minimal and purchase price higher but still might be cheap compared to California.Example a 4 unit in another state for an A location might be 400k but in California maybe who knows 1.5 to 2 million or something like that.
