As Laura pointed out, aggregate websites are not the best places for find property values.
Please read my blog "Big Banks - to big to love," here on Trulia to get a look at how aggregate websites 'value' compare to real world values. Yes, I through Trulia and Zillow numbers into the mix.
Aggregate websites are for entertainment purposes. Soliciting advise from strangers on the internet is universally seen as a truly bad idea. Yet, when it comes to something as important as a home purchase. we somehow believe invalidated sources showing random values should be viewed differently.
Read my Trulia blog, then, at the very least, refer to the website that come closest to the real number.
Best of success to you.
