Boomer Housing Turnover

"As baby boomers relocate or downsize in retirement, or simply die off, they will release a very large amount of housing onto the market. Older homeowners (aged 55+) accounted for about one third of housing turnover in the U.S. between 1997 and 2007, and this share will increase as the large baby boom generation continues to age into their retirement years."
