I've noted before about some older couples basically "stuck" in a 4-5 bedroom home.  They might like to move, but they look at their 3% interest loan currently and wonder why they would pay 7% if they bought now.  They'd downsize and basically pay the same amount on a loan, or more.  My realtor friend says this is an issue, even for him personally.  He has a 1960s 4 bdr ranch in a nice area that would sell for a lot, but then what?  So he stays put.
I got a call yesterday from a realtor offering to buy my place.  He left a message to that effect, no pricing of course, nor would I be willing to sell.
