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.
It's 2016, and people still think that if someone moves into your neighborhood, someone else has to move out. 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.
Ok, let's say we double supply.
All the houses are now either twice as high, or half as big, or maybe the trees were cut down and the bushes ripped out to make room. There's twice as many people & everything therein. Is it still the same nice neighborhood?
