Portland housing prices are growing faster than almost anywhere in the nation. So the Portland city council has decided to address this problem by building 1,300 units of “affordable” housing, adding less than one-half percent to the city’s housing inventory.
How are they going to pay for this? By taxing new homes 1 percent of their value. Because new and existing homes are easily substitutable for one another, when the price of new homes goes up by 1 percent, the price of existing homes will also go up by 1 percent.
The problem is that politicians don’t understand the difference (or hope voters don’t understand the difference) between “affordable housing” and “housing affordability.” The former is something governments build to help people who are too poor to afford decent housing. The latter is the general level of housing prices relative to the general level of incomes. Building “affordable homes” addresses the first problem, but not the second–except in cases such as Portland where affordable housing makes housing less affordable.
In short, Portland is using the wrong tool for the job. The result is that, instead of making housing more affordable, it is making it less so. Of course, developers who will build those 1,300 units of affordable housing will benefit, and they were probably the leading lobbyists behind this idiotic idea.
