@Robin Searle in my area- St Augustine, FL- we have specific zoning requirements which have been set before Airbnb and VRBO became popular. It is a tourist town to a degree.
Many people and even insititutions entered the STR game and purchased properties at high prices, anticipating returns 5x that of standard long term rentals (1 year, 18m etc). These people didn't look into the zoning requirements and purchased in neighborhoods that only allow 1 rental per 7 day time period. They have been renting on a nightly basis at much higher rates than a one week rental warrants. Our city has just announced that they will enforce the existing law. This has obviously lead people to become worried about their returns.
I never entered the STR game because these properties sold at overinflated values which wouldn't cashflow, should the gov't enforce the existing law. Now it's happening and I'm just waiting to pick up the cheap properties people sell at a loss because they didnt do their due diligance.
Side note, people are talking about suing agents because they were “mislead” about zoning. It will be interesting to see how it plays out here.
