Tax the crap out of them, for sure.

But given how much of a housing crisis exists right now, I wonder if it makes sense to enact a 1-2 year ban on AirBnB rentals in the state as a temporary emergency measure, then figure out a taxation scheme as a long-term disincentive. Folks who want to buy starter homes or rent in the state need relief now, and unfortunately the STR slumlords causing this problem already benefit from a number of tax loopholes, so I'm not fully confident it will fix the crisis. Surely not until next tax season, when the tax bill comes due.
