From the Wall Street Journal comes some interesting data to ponder on this Friday.

More than half of all homes sold last year and so far in 2013 have been financed without a mortgage, according to an analysis by economists at Goldman Sachs Group.

The analysis estimates that around 20% of all homes sold before the housing crash were “all-cash” sales (or around 30% of sales by dollar volume). But over the past seven years, the all-cash share of sales has more than doubled, increasing by more than 30 percentage points, according to economists Hui Shan, Marty Young and Charlie Himmelberg.
