I have a potential theory of future revenue for them - as "work from home" becomes more accepted and popular, working vacations or nomadding even within the united states will become a lot more popular for couples looking to get away, singles looking for new locations to try out and even families on trips.
There's been this sweet spot with AirBNB where you can rent a place for 1-2 months for a relatively small monthly premium over a 12-month lease that I've been planning to take full advantage of this year, already having been remote. A lot of AirBNB hosts have started preferring these sorts of arrangements because people are less likely to cause trouble. I can't help but think the AirBNB that replaces hotels might drop by a lot, but the mid-term monthly rentals might bounce back a lot quicker as people become less location dependent on work. I know I absolutely am planning to go somewhere warmer in the winter months.
There's still a huge opportunity in a hassle free monthly rental experience. Month to month through almost any legacy property management company is an absolutely dreadful experience with huge up front deposits and being treated basically like a criminal. I have no idea how big this market is admittedly but its been a very interesting value prop for me.
