For those of you shaking in your mortgages while you're tuning into our show on plunging home values, this extra credit will either make you feel better, or... well, worse. If you've been listening to Dean Foust's prediction that home values have to drop even more, well, just skip to the next post (it's good escapist fun). If you're a die hard realist — check out this nifty little home price calculator. And listen — don't lose your nerve. Information is power, and at least you're probably getting some good use out of your home — even if it is falling in value.
