Will, it's all market manipulation and expectation management.
"good" is not an absolute, it is just relative to everything else.
Turning the thermostat down 1 or 2 degrees is a sign of hardship for some, but a dry, frost-free night in a doorway is "good" for a rough sleeper.
Values are never going to hit the heights again, except maybe for whatever the future market decides is desirable.
I've only ever bought below market value and so have no expectations, realistic or otherwise.
