The government.
The section 8 landlords are enjoying some serious schadenfreude right now because even though they only cash small checks once a month they're the only ones still cashing checks at all.
Short term rentals have an effective monthly rent far in excess of the normal monthly rent for equivalent accommodations. With this payoff comes risk. The money source can dry up on you much faster. I have no more sympathy for people who went all in on AirBNB than I do for people who went all in on day trading.
