They just bought 2 years ago and want to sell? In a normal market, the transaction costs make such transactions very undesirable.
If they are tired of their condo today, they’ll be more tired of it in 5 years. Sellers can only hold out for so many years for the market to come back. They’ll give up eventually.
I expect this downturn to last 7 to 15 years (i could be wrong). They’ll give up because of old age, divorce, savings running low, etc…
