> However, when a space loses a tenant, the bank can't just drop the price for the owner, the same as you can't just pay less on your mortgage if you get a lower paying job. You can always pay less on your mortgage or any other debts if you are in a crisis and negotiate with the lenders. They prefer this immensely over not receiving anything at all. And in the long run they also receive more interest this way. It's very common especially for businesses to enter these kind of negotiations with the banks, and not very uncommon for individuals either. So it makes much better sense for everybody involved to sublet these spaces for market value, even if that income doesn't cover the original mortgage, because something is better than nothing. Somewhere there's a giant perverse incentive in situations like this.
