Zillow versus Realtor.com?

[Mike Selander]

I have seen a difference between Zillow versus Realgor.com on the same address? For instance on Zillow I saw a property listed as an auction, lender owned for $136,000. But it is listed as $249,900 on Realtor.com with no comments about being lender owned. I have found this on a lot of other properties. What site do I trust?

I hope this is the right forum for this post.
