A National Association of Realtors spokesman tells CNBC that homes valued at $750,000 fell by 47% in the year ended in November. Homes valued at $400,000 or less fell by only 3% during the same period.
The driving force behind that has been the decline in the stock market. High net worth people are more effected by that than lower- and middle-income workers. The average household with a net worth of over $1 million has lost 30% of its net worth recently -- and that's curbing their demand for luxury homes.
Tightening in the mortgage market for jumbo loans is also a factor driving the decline in that market.
