The solution there is to restrict operation of vacation rentals to certain neighborhoods, limit total percentage of housing stock allowed to be converted to vacation rentals, extra property taxes on vacation rentals (versus regular rental properties, which still contribute to housing stock). If you make vacation rentals more expensive to own, you drive down the ROI on them and make them less attractive to investors.
