Do you mean the Ike crisis or the mortgage crisis?
If the mortgage crisis, I think HOU is still doing OK due to high oil and gas prices....plus, in general, I'd probably take out a mortgage on the house instead of buying for cash. Not only is a mortgage (generally) cheaper money than you can get anywhere else, but if you spend the cash, it's gone forever..if you take a mortgage, the outstanding debts are settled against any assets you own, and if you have more debts than assets, your debts die with you.
I think the only reason you'd want to own the house free and clear is if you have an expensive medical condition and you want to get medicaid....or if you want to sheild assets from a lawsuit. It's my understanding that your primary residence is not seizable by the courts.
If you have the money to buy for cash, you probably have enough assets to get a mortgage even in today's economy.
I am not an investment advisor. I could be full of s***. Do not take advice from an internet message board seriously. Contact competant financial or tax advisors before you even wipe your axx in the morning.
