Super affordable, no monthly hosting cost, can upload directly to Zillow.

They are relatively affordable, and a national company. 

And, that you can afford the payment without the use of rent, then I would say 3 months of the full payment, if you need the rent or a big portion of it to make the payment then 6 months would be enough in my opinion.

Can the Fed afford to pay everyones mortgage for 1 year?

If you can, work out a payment plan for them to pay any of the rent they can't afford to pay over the next few months. 

In past recessions, people who had enough disposable income and lived close by may decide to take a more affordable vacation.

My point is, if I could make more income or sell my investment property for a good return in a few years I could just keep renting (2k a month) while gaining equity in the investment property and ultimately be able to afford a more expensive personal property.

The more affordable ones may not be in areas that have transitioned - and maybe never will. 

Seem like B class is the way to go during this time...C class: no job, can't afford rent and I can't evict so at least a few months of no rent coming out and mortgage still need to come out :( and  A class : no Cash Flow.  

Im not sure but perhaps i would describe Tulsa more favorable as a reliable, predictable, and affordable buy and hold long term rental market; while DFW more favorable as a market with pockets that still have nice growth potential for buy and hold rentals and heavier appreciation potential.
