The Most Splendid Housing Bubbles in America: Biggest Price Drops since Housing Bust 1. Record Plunge in Seattle (-3.9%), Near-Record in San Francisco (-4.3%) & Denver. Drops Spread Across the US

By Wolf Richter for WOLF STREET.

This is the first month in this cycle that the S&P CoreLogic Case-Shiller Home Price Index, which lags reality on the ground by 4-6 months, is showing house price declines in all the metros in the index.

In Seattle, the month-to-month plunge was the steepest on record (-3.8%). In San Francisco, the month-to-month plunge (-4.3%) was the third-steepest on record, outdone only by the two worst months during Housing Bust 1 in 2008. In San Diego (-2.8%), Los Angeles (-2.3%), Phoenix (-2.1%), and other metros, the plunges were the worst since Housing Bust 1. And the declines are spreading across the country to other metros, including Dallas, Boston, Washington D.C., and Las Vegas.

These are serious declines for the Case-Shiller Home Price Index, where each month is a rolling three-month average which irons out the month-to-month variability.
