Perhaps Zillow is more interested in showing the longer-term market value of a home so buyers know if they're being asked for a high demand-driven price. A tight market like that can spring up quickly and fade away just as quickly. At some point most people are going to look to resell or to at least not be forever upside down because they bought during a tight market.
