Even if they don't move half a continent away, they'd still need to buy a house, furnish it, fix a bunch of stuff, then live in it for <7 years, fix it up again (atleast cosmetically), sell it, buy a new one, all the hassle of moving and new furniture because not all of the old stuff fits, new fixes of stuff that was just cosmetically fixed, and in <7 years again.
