How far off the mark is Zillow for Sacramento home values? Part II...

I posted a couple months ago about Zillow values and how far off they had been for my last few transactions...I thought I would follow-up that post with some new information since that post was basically concerning Sacramento area home sales from the end of February. Perhaps Zillow had the opportunity in the last few months to update their mathematical algorithms and get to a more accurate price? Let's see...

In my last post I referenced my four most recent closed sales, so I will do the same here from my transactions closed in about the last month (and by the way I am writing this post as of June 13, 2013 -- so that is the date and basis for the Zillow information)...

8046 Otium Way, Antelope, CA 95843; this was a home I listed in Antelope. The original listing price was $209,000, and this sold on 5/9/13 for $225,000 -- 7.19% above it's listing price. Zillow's Zestimate: $197,503 -- approximately 13.92% below it's selling price.

5836 20th Avenue, Sacramento, CA 95820; this was a home I listed in Sacramento close to the Tahoe Park neighborhood. The original listing price was $159,900, and this sold on 5/16/13 for $168,000 -- 5.06% above it's listing price. Zillow's Zestimate: $154,695 -- approximately 8.60% below it's selling price.

4335 54th Avenue, Sacramento, CA 95820; this was a home I listed near Colonial Heights, a neighborhood just to the south of Tahoe Park. The original listing price was $239,000, and this sold on 5/31/13 for $236,000 -- 1.26% below the listing price, and only because we had a craptastically low appraisal to deal with (appraisal was $235,000 on a $245,000 contract). Zillow's Zestimate: $143,631 -- approximately 39.14% below it's selling price. WOW.

1900 46th Street, Sacramento, CA 95819; this was a home East Sacramento in the Elmhurst neighborhood near UC Davis Medical Center, and I represented the buyer. The original listing price was $350,000, and this sold on 6/10/13 for $356,000 -- 1.17% above it's listing price. Zillow's Zestimate: $310,701 -- approximately 14.53% below it's selling price.

So based on this, I can conclude that Sacramento Zillow values are still way off...I'll check again in a few months and post again.
