Not really an AIBU, more a hypothetical question really. This view comes up a lot on MN, and I'm interested in the detail of what people actually imagine when they say it. What type of property should they be giving up? What type of property should they be moving to? How old is old? What about younger people who under occupy a property? For example 2 friend couples, have recently downsized. Both from a 4 bed detached, one to a 4 bed semi, and the other to a 3 bed semi. Their homes were bought, one by a young professional couple, and the other by a couple in their seventies, themselves downsizing. If you hold this view what do you visualise?
