I can see that with the Federal Reserve pumping money that it puts off any sort of downturn for the next 12-24 months. 

What sort of issues could I be looking at with something like this? 

I'm going to call the lender that did their refinance tomorrow and see if there is any sort of catch, especially on investment properties.Even if this crazy method doesn't work, wouldn't a simple interest mortgage be a big deal for rentals?

Hi Jasraj, I completely understand where you are coming from because my Data analytic brain wouldn't budge without some sort of food(read data).

@Justin Mayne i deal with this sort of thing often with folks buying houses for us to manage. 

She has a hair salon which has been forced to close down during the pandemic.

Assisted Living aka older retired folks the mixed rentals are ok, but need some sort of live in nurse/management to prevent or attempt to prevent bad situations....Co Living long term rentals are ok and are actually becoming popular. 

Today, Class C were hit the hardest, since many tenants who are employed in the service industry (restaurants, hair salons, etc) are out of job, and cannot afford to pay rent.

You gotta think the ones selling right now either have a loan maturing soon, have identified an "up-leg" they want to trade up for, or are spread to thin and need some sort of a liquidity event. 

@Adam Sankowski You refer to the notorious "do not invest zone" which indicates to me that there exists some sort of community/neighborhood rating scheme.
