If you could buy a house today for $1,000,000 or tomorrow for $500,000 you are going to tell everyone that today isn't a bad day to buy becasue you are going to live in it?

"It is never a bad time to buy a home if it is where you plan to live. Real Estate ALWAYS increases in value (Love Canal excluded) over time even though it has it's peaks and valleys."

It will be their grandchildren that see a return to the previous highs.
So does the Dow--in the long run. The problem was elucidated by John Maynard Keynes: "The market can stay irrational a lot longer than you can stay solvent."
