Yes, but what is available to them? A 3 bed semi miles away and miles from anywhere that still needs adaptation? Not very appealing for most and certainly not future proofed re support needs. Best to stay put in a large but familiar house, even if unsuitable.Other than not being able to get a bridging loan. If they don't need a bridging loan they can put their house on the open market like everybody else, then look around for whatever suits them.
