As reported by Inman, a recent study commissioned by Redfin has found that listing sites such as Zillow and Trulia have shown to be much less accurate in providing listing information than dedicated realtor sites.
Consulting firm WAV Group, who conducted the study, found that, in 11 major markets, listings were less timely, informative, and accurate than their respective counterparts on three broker-operated sites. The reason for this is because most broker-operated sites feature direct information pulled from MLS sites. Trulia and Zillow rely only partly on MLS sites, also receiving information from syndication and direct input from realtors. As a result, old listings and only partial information will sometimes be displayed.
In the parameters of the study, which featured randomly selected zip codes, it was found that 36% of the listings on Zillow and Trulia were actually no longer for sale, as compared to a less than two percent finding on broker sites. In addition, while 100% of the MLS listings were present on broker sites, only about 80% of MLS listings could be found on Zillow and Trulia.
While sites such as Trulia and Zillow are great for quick looks and basic statistics about communities and neighborhoods, when providing more in-depth analysis and accurate listings, they can be found lacking. This is part of the reason why we put so much time into creating our brand new site, ExclusiveCollection.com.
We provide in-depth articles about all the communities in the Central Florida area that go beyond what you’d find elsewhere. In addition, our neighborhood search offers accurate and up-to-date MLS listing and map data that make finding the perfect home an easy task. So give it a look, and tell us what you think!
I saw the CEOs of these big firms speak on issues of syndication at Inman in August. It was intriguing.
Can't tell you how many discussions I have had about the accuracy of Zillow with clients. Because it is there, they do look, then they have to learn the real numbers.
Zillow and Trulia can be very frustrating for Realtors when consumers solely rely on their information and are reluctant to accept more accurate and up to date info - particularly when they find their dream house that has already sold or Zestimates that aren't even close.
Hey, if it's on the Internet it must be true and accurate, no?!? If consumers want accuracy, they should contact a local agent who has MLS access.
As a former Calif. real estate appraiser I can attest to having found both services to be of no use for valuations in my experience. They routinely ran way off from the appraised value, often by 20%-30%, and usually on the high side.
I think the accuracy of Zillow and Trulia has been an ongoing issue for some time. I recall a particular case, where a mobile home in a trailer park was given similar valuation to custom homes on the opposite side of a creek.
Michael, it is good to let people know how accurate(?) Zillow and Trulia are! (And they don't claim to be accurate either!) And yes, that's the main reason they should work with professionals.
Sites like Zillow are fun but it's rather like listening to gossip-only a percentage of the info may be correct.
Michael - I get calls from client all the time wanting to see homes that are no longer available except online.
I'll check for a rental ZESTIMATE for a property presentation; however, I don't post directly to these sites because it is a waste of time and energy
It's always an interesting conversation about large real estate sites online... and yet they garner a large portion of viewers. Learning to use those sites can be very beneficial.
I love Rich's comment (#7). I think that's the best way to look at it. Zillow is frustrating sometimes, but it does make us look good.
The problem is when people look to Trulia or Zillow as an equal to or replacement for the MLS. They are simply advertising sites such as a local newspapers. The problem starts with the automatic feeds they use to input listings. The problems get worse when listing agents do not check or edit their listings properly.
Oh, they're accurate alright. Just as accurate as last month's newspaper classifieds!
I've wondered about these same things many, many times. Thanks for clearing things up and providing this info.
I wish I could create a company that does absolutely nothing productive for consumers and dishes out old and obsolete information but yet still makes millions. Yeah...I think that's probably the way to go. What's that you say? Zillow and Trulia already cornered the market on that? Damn it! LOL Good post!
Hi Michael,
I hear so much crazy information from Clients that drives me crazy.....just use what I supply from the MLS PLEASE
Good Morning. I have found that the estimate of a propertys worth on Zillow is pure garbage both under estimated and way too much. Really don't understand how they can box all markets into their one program.
Yep! I came here from Praful's reblog and this is absolutely right. Idaho is also a non-disclosure state and it's a difficult and frustrating conversation to continue to have with people when they are trusting that site for accurate information. Zillow is much more common than Trulia. - Kasey
