I think there truth to that.
The stats do indicate that were are much more mobile society and that households move on average once every 5 years. Jobs are no longer guaranteed and people often need to move for professional reasons.
Buyers who buy in a down market need to consider their future job prospects before buying. If they sell as the market continues to decline, they’ll loose a huge amount because of depreciation and transactions costs (plus all the years of ownership premium they paid and won’t recover. That premium is real money since it’s savings they would otherwise have).
