Due to 1031 restrictions we can't usually do syndications or Funds.2) Individual rentals - We could roll this into 10-20 individual home rentals (love the appreciation, like the cash flow, hate the complexity of 10-20 individual homes/insurance/loans etc.)3) NNN leases - This may be the simplest option to park a lot of passive cash, however with approx 5-6% yields it seems like the market is undervaluing risk in retail/hospitality/restaurants (where most of the NNN lease deals reside).I'd love any other thoughts people have.

@Jim LinThe simplest way is your mom deeding the house to you, in her estate planning, but still collecting rent, handle taxes and bills as before is for you to provide her a NNN Master Lease, with nominal payment to you.

I'd say the simplest and most cost effective step would be to house hack where you live... this reduces or eliminates rent, and you will learn the ropes of REI / landlording. 

Yes, it's possible and actually quite realistic, IF you go about it with a plan.The simplest formula for SUCCESS is 1) Make a plan, 2) Work the plan.Please query the subject of "Self Storage" here on Bigger Pockets and then take a look around.  

How quickly the coronavirus mocked our assumptions and challenged our simplest routines.
