In the next 30 years folks in their 80's may not be able to live in their homes because of stairs. What happens next?

I envision houses like that purchased by young families, while the elders use the proceeds to buy smaller one-story houses or move to retirement communities.

Century: When I look ahead, I don't think of housing in terms of one story or two story. What I see is a glut of homes on the market when the boomers try to downsize or go into assisted living. Boomers came from families with 2 or more children. Many came from families with 4 children. Most of them are home owners and most of them had smaller families. They will have more homes on the market than there are buyers for so that is the real problem I see in the future.

When you are taking 30 years from now, it's kind of a mind bender. I'm 63 and I don't know if I'll see 93, but I own my home and that asset has value now, but will it have value when I may want to sell or will the market be flooded with this great population of boomers who are making changes?

There are developments that cater to those who want community and single story living. Price plays a roll is what some can afford. Right now, I think most can downsize, even in this market because there is a level playing field. Twenty years from now, however, I see big changes and so many houses on the market.
