I once again see disturbing trends rearing their ugly heads in the U.S. housing market. Twelve years ago, I warned about the housing bubble long before it burst—then living in the Washington, D.C.-metro area. Now my vantage point is San Diego, where home prices soar and sales (finally) start to stagnate.

Justification, set against measurable trends, often is a fantastic measure that something is amiss.

Metaphor: In film “The Big Short“, set during last decade, a Florida real estate agent drives around a group of Wall Street investors trying to discern whether or not there is a housing bubble. As they pass property after property for sale, she explains: “The market is in an itsy-bitsy little gully right now”. Eh, yeah. That gully later became a giant sinkhole. This morning, I received a newsletter from a local realtor that claims: “Pending home sales were sluggish in April as low supply reared its head”. Crazy thing, I see plenty of inventory for sale—and for increasingly longer times today than four or five months ago. The newsletter’s assertion rings like a justification worth concern.
