At the height of stock market frenzies, millions of eyes are glued to the ticker: the thin strip that recites stock prices as they rise and fall.

Ambitious entrepreneurs have set out to do something like the stock market ticker for home prices with the new website Zillow.  The creators use home sale prices to estimate the value of (evenutally) every home in America.  You can have a bit of fun right now by clicking on Zillow and typing in your home address.

The site is still new and no one is advised to rely on the estimates for decision-making.  But for real estate investors, it's an easy and efficient way to roughly estimate an area's comparables.
