This figure is inflated somewhat, though, since sales in November of last year were depressed by the implementation of new closing disclosure requirements. Total inventory of existing homes available for sale fell to a 4-month supply, and it was 9% lower than a year ago. The median existing-home price was 7% higher than a year ago. Since sales of previously owned homes measure closings, the November data was not affected much by the increase in mortgage rates seen since the election.
