Portland resident here. What this article doesn't cover, is now locals are victim of gentrification. Rent prices are almost 2x, out of state buyers are throwing all cash offers on houses, and overall housing supply is low... I'm sure the commercial market is just as bad. Interesting times.
Rising demand is great. It means people want to enjoy your neighborhood. You can either meet that demand by increasing supply, or you can restrict the demand, and let certain people be outpriced by the market.
Locals aren't victims of gentrification. They're victims of zoning laws and nimbyism.
