AirBNB is a very small part of the housing problem in Portland. As of 4/30/2015, Portland area had 1,110 properties categorized as "Entire home/apt". That same metric was 814 on 4/30/2014. Portland also has legislation specifically for AirBNB (they have to register with the city, pay taxes and get a "less than 30 days" lodging permit). The primary housing problem here is an influx of people from more-expensive cities (LA, SF, Seattle, NYC) moving in and snapping up homes to actually live in. Meanwhile the city is making it difficult for developers to add any real housing density within the Urban Growth Boundary (and instead are thinking about expanding the UGB. Ugh.). So there's no real "problem" aside from Portland is a desirable city to live in and people are flocking to here.
