Literally, the condo across the hallway from us sat on the market fir over a year and finally sold in foreclosure for 45k in 2018 and now they are selling for 180k because people think they can cover their cost with STR income. When a lot of people have the same idea and jump into the same business at the same time not all will be successful because they are flooding the market with a product. There are only so many people who need lodging on a given weekend or week.
To go along with
@Christy 's comment above, Vermont has an absolutely critical shortage of full-time housing right now. If STRs are not profitable enough for landlords, LTRs are desperately needed and would seem like an ideal solution (and less expensive and labor-intensive than turning over a unit every week or weekend).
As an anecdote, I bought a small condo on Mt. Ascutney in 2018 for $65k. I could sell it for twice that right now. But I live here, and consider myself very, very, VERY lucky to have a stable housing situation in Vermont right now.
There are 16 units in our condo as a whole. When I moved here, only three were owned by people who lived in them full time. There were a couple of renters and the rest of the units were unoccupied by out-of-state owners who stopped coming up when the Ascutney ski resort shut down. (The late-1960's shag-and panelling decor in many of the units was a source of much Redfin-browsing hilarity for a while).
Now? Almost every unit is occupied by an owner who lives and works here full time. Even at the higher purchase prices, these units are still an affordable housing option for a single person or a couple. We're within commuting distance of DHMC and the Upper Valley, so it's lovely without being isolatingly rural.
All of these new owner-occupants have injected new energy into our condo association. Having actual residents make decisions about long-term infrastructural maintenance helps protect the value of our assets (the absentee owners tended to do the absolute minimum maintenance, and only when forced by necessity, such as a significantly leaking roof) and we're discussing some creative uses for our land, such as a community garden.
I can't speak to the needs or the economic future of STR landlords, and I recognize that I'm coming from a very specific perspective when it comes to Vermont real estate. But if the STR sector took enough of a hit that converting to LTRs became more common, that in my mind would be a tremendous benefit to Vermont workers and families, many of whom are the people staffing the ski resorts we love so much.
