An estimated 73 million boomers, ages 60-78, live in the US, roughly 25% of the population. They own around 38% of US homes.....possibly the most potent source of future housing inventory? Many people shed their homes - or downsize - after the age of 75 years old....some estimate that by 2035, the number of homes owned by baby boomers will drop from 32 million to 23 million freeing up 9.2 million homes in the US housing market. Many will require renovation/restoration and/or rebuilding. (WSJ)
