Some clients with STRs are doing well. Some aren't. Those that aren't are the larger, 4+ bedroom STRs that are geared toward group stays and events. The small 1-3 bedroom are still doing okay. IMO, the airbnb market got carried away the past few years. It wasn't uncommon to see $500/night places in areas that had clean and reasonable hotels for $120/night.
As far as clients go, most of mine are doing fine. And there's value that we can provide in bad times as well as good. I don't expect an material exodus to DIY software.
Those that overleveraged are exposed IMO. In the past few years a significant percentage of the population bought homes at inflated prices and vehicles at inflated prices, and are up to their necks in debt. It's "doable" as long as there are two incomes, but if one spouse gets laid off, they'll be in dire straights very quickly and (I imagine) will need to sell the house. A lot of that happening at once will put downward pressure on house prices.
In this economic environment, the smart move is deleveraging and stacking cash.
