Cash is king in red-hot Portland real estate, representing a full one-third of single-family home sales in 2014. Lee van der Voo's seven-part series on the Portland housing market has uncovered in stark outline the often-obscured influence of cash from developers, foreign buyers and Wall Street in driving affordable housing from the city. Twenty-six investors who purchased more than 10 homes for cash in the listed market in Multnomah County through the recession. Average Black and Native American households priced out of the city. A publicly traded company that is renting out more than 200 Portland-area homes in a new twist on the asset-securitization that drove the Great Recession. The pension funds of teachers and police officers invested in cash-rich Wall Street landlords who compete on the housing market with the very middle-class professionals whose pensions they hold. With van der Voo's reporting, an economic crisis that everyone in town talked about but no one could explain was given names, faces and numbers — and a hope of being fixed.
