I believe the parent comment isn't bemoaning the business practices of these landlords but instead addressing the unethical behavior of its patrons.

> the unethical behavior of its patrons

the patrons apparently don't believe that their behavior is unethical, and in fact, think that the dictates of their rules are unethical, and potentially illegal too.

I think few are willing to sustain a COVID-free lifestyle indefinitely. Using induction some people probably conclude that they might as well not bother.

I see the reasoning and don’t think the ethics of our pandemic behaviors have been fully discussed.

That's because the bank still expects the mortgage to be paid.

If this was true, we'd see landlords with paid-off mortgages waiving the rent. Since we don't see this on any major scale, we can only conclude that mortgages are inconsequential to landlords demanding rent-payments.

A mortgage is not the only cost of owning a property. Taxes are a third of my mortgage payment every month. Other than the IRS delaying tax day by 3 months, I haven't seen any delay or waivers of taxes due.

In addition, there's basic upkeep and maintenance that you're required to perform to keep a building insured, let alone to make it re-openable at some point.

That’s because pensioners and investors expect to be paid their due.

Strikes me the gym and the bank could probably come to some kind of arrangement?

I think the Landlord would feel left out if so.

A lot of landlords accept that their tenants can't pay rent for now.

It's not like there are alternative tenants who can pay around.
