Also prevents rental scammers from using your full frontal pic and address when there is none. 

Since I had a few months of expenses saved for emergencies, I looked at the future mortgage payments as an emergency account to my already existing emergency account, or a kind of belts and suspenders preventative layer I could always employ if needed.

They mainly do this to catch problems for preventative maintenance before something becomes a major issue.

Is there anything preventing someone from doing all of these skills at 1 time or another just to make sure business never slows due to market ups & downs?

(think 2 am clogged sinks) but benefit from more units under single roof; easier to find property managers for more units; higher income and more income opportunities (vending, laundry & parking & storage income). 

What we have seen are a combination of “helicopter monies” (stimulus checks, extended unemployment, loan/grant programs) and relief programs (relief for COVID treatment costs, renter relief programs) all of which have helped to keep the economy from collapsing and have prevented many people from suffering.

It would be very unusual for a condensation line blockage to cause problems this time of year here in Birmingham because it's been cold here lately...so nobody has their air on...and the unit doesn't produce condensation in heat mode.For a future preventative measure though, I would recommend you have an HVAC company install a pan underneath the unit in the attic (if there's not one there already) and attached to that pan, ask them to install a "float kill switch".

I would say I turned out pretty lucky given that the moratoriums might have prevented me from evicting him until next year.

I seem to be prevented from posting contact details here but you can find him I'm sure...

Any suggestions on how to prevent this in the future?
