Zillow is a popular site with the general public--who isn't interested in what someone thinks is the value of their house, and those of their friends and neighbors? What many people don't understand is that the Zestimates shown by Zillow can't take into account the specifics of a house and the current market conditions.
Periodically I give examples of Zestimates of properties in California's San Mateo County and then let you know what the home actually sold for. My habit is, when I first take a listing, to take a screen shot of the Zestimate and them compare it with the actual sales prices.
Let's take a look at a few from the past 5 months:
Sales Price: $951,000
Sales Price: $640,000
Sales Price: $735,000
As you can see, buyers are not doing themselves a favor in our area if they think the Zestimate reflects market value of properties in San Mateo County.
My advice: look at Zillow, enjoy the entertainment value of it ---- then call a Realtor® who can truly advise you about the market value of your property, and discuss ways you can maximize your gain should you decide this is the right time for you to sell.
