Case-Shiller continues to reveal a slight dip for 7 of the past 8 months, with a minor uptick in home prices in February. This broad index masks significant regional differences: home prices on the West Coast of the United States declined, while in the East prices actually went up, year-over-year.
Zillow's Zestimate is based on a nationwide averaging algorithm, so it's often unreliable. Zillow's employees live and work in Seattle, WA. Most have never seen the Palm Beaches and don't know anything about the local communities, amenities, what's locally popular, let alone a home's interior upgrades, etc.
