From Forbes:

My good friend, banker-scholar Alex Pollock of the R Street Institute, has shared with me some startling new data. High priced, comparatively luxury college student housing has been popular, and in this century lots of apartment complexes have been built with many amenities —granite or marble counter-tops, fancy swimming pools or saunas, etc. With unemployment rates below four percent and  low overall real estate delinquency since recovering from the traumas of a decade or more ago, this sector should be booming. But according to a story published by Wolf Street (Wolf Richter), delinquencies are rising dramatically.
