Actually sounds like people have a lot of choices. Call the bank, do a deed in lieu, and get another mortgage in a couple of years. No fuss, no muss.
For me, that likely ain't gonna work. Short of some kind of Second Depression with 25% unemployment, I don't foresee the Puget Sound housing market "collapsing". 5%, 10%, maybe a 15% drop, but that's about it. And I fully expect the reverse to continue for some time with periodic plateaus.
For me, in this market, I'll be so priced outta another house should such a thing ever befall me, I'll let the CCs go and keep the house.
