&gt;the service&#x27;s impact in Seattle was negligible. More than 80 percent of Seattle hosts were sharing their primary residences,<p>That second sentence doesn&#x27;t follow from the first. I know people buying houses in Seattle today who are willing to pay more than they would otherwise for a place with an extra bedroom, or even better a basement apartment, because they&#x27;ll make it back and more in Airbnb rental income. And they absolutely don&#x27;t have any plans to rent out the third bedroom to a regular tenant ever, so this is potential housing now off the residential market for the foreseeable future.
