I thought this would be a good time to compare the two services, and pit them against what are real world values for recent home sales in the Foothills area of Tucson AZ. This is where I live and work, so I'm very familiar with what goes on here.
I chose a total of 6 homes from the Tucson MLS that have sold in the last 3 weeks, 3 months and 6 months in a price range from about $500k to just over $1mil. I also chose homes that I am familiar with, homes that I have seen and shown to clients or at least previewed on my own in the past. I did this because I wanted to avoid picking a home that was for some reason odd, really unique or extroadinary, and therefore not representative of homes in that area.
I entered those addresses in zillow & reply, and I did not make any adjustments to the zestimates or valuations provided by Zillow or Reply for these homes.
Here's what I found,
--------------------------------------------------------------------------
1. 2149 CAMINO LA ZORRELA Tucson, AZ 85718
Zillow = $609,993
Value Range: $536,794 - $847,890
The Value Range indicates how much data we have for a home. The smaller the range, the more data we have, and the more accurate the Zestimate.

Reply! Confidence Rating is a complex proprietary calculation that is used to determine the accuracy of the latest Reply! Home Valuation that we have calculated. Since there are so many variables that go into producing a home valuation, Reply! provides this confidence rating for the purpose of providing transparancey to the consumer around how accurate a particular valuation is. For example, a home that has an abundance of comparable homes sales with accurate and up-to-date home detail information will score a higher Confidence Rating than would a home that had less comparables with less home detail information.

I thought this would be an easy test since all of these homes have sold recently and the sales data is publicly available. But despite that both zillow and reply are pretty far off the mark in their valuations.
The zillow value range in most cases seems to at least book-end the real world price, albeit by a very wide margin.
One other factor here is that these homes are not in a cozy little subdivision of similiar homes of about the same size, of similiar vintage or amenities, and they're not on cookie-cutter lots.
These are all in areas of the Foothills where the homes are more or less custom, they cover a pretty broad age range, and the lots are not cookie-cutter. So it's a lot tougher to pull a value just based on a bunch of data.
But they both claim that they can do it.
And even if we were to consider homes that are more comparable in terms of size, age, amenities and lot size, how does the data that they count on account for condition, improvements, upgrades, how well a home shows and all the other factors that help determine value.
In any case I think that at this point these are interesting, innovative services that are fun to play around with, and that may be useful in providing a broad value range. But I also think that Zillow and Reply should back off on the claims they each make on their homepages;

or at the very least provide a big warning on the homepage that advises people that these valuations cannot be counted on to be accurate - Do Not make financial decisions based on them. It's too important!
I'm sure that's buried somewhere in the small print, but who reads that stuff.
