CNN: Selling your home? Here’s how accurate online estimates are

The housing market is booming and chances are your home is worth more than it was a year ago, making it a tempting time to sell.


But how much can you rely on online estimates, like Zillow’s Zestimate or the numbers offered by Redfin or Realtor.com?

“There is a kind of sticker shock that sellers may have right now,” said Krishna Rao, vice president of analytics at Zillow. “Even if they may have thought about selling a couple years ago, to look at where the market is now can be surprising.”

Learn why pricing right matters: homes priced correctly sell 19 days faster and for 3.8% more ($15K+ on a $400K home). Excerpted from this video posted by Pauly Campanaro:

@SacAppraiser | Ryan Lundquist Zestimate history. This property in Roseville listed at $349K, and the Zestimate matched the list price at $349K despite comps being above $600K. After 11 days the price went to $699K (sold $638K). Today's Zestimate shows no history of $349K. Maybe a brief Zestimate gets erased?
