Chronicles of Data Collection II: Non-Disclosure States

It seems many people are confused regarding what a non-disclosure state (or county) is.  Hopefully, we can set the record straight for those of you wondering.  What does the term “non-disclosure” really signify when it comes to property records? It’s a tricky question given that people or companies use the term differently given that exact definitions can vary by location.

The big, big picture is that in a non-disclosure state, transaction sale prices are not available to the public.  There are two main causes for states being considered non-disclosure:

Since we rely on public county records as our primary data source driving our Zestimate algorithms (which take comparable sales prices into account), it poses a challenge to calculate accurate Zestimates when sale prices are not available.

The following states are considered non-disclosure: Alaska, Idaho, Kansas, Louisiana, Mississippi, Missouri (some counties), Montana, New Mexico, North Dakota, Texas, Utah, and Wyoming.

If you live in any of the above states, at least you now know why we don’t currently have sales records in your area.  As we improve our data and algorithms, we are continually looking for additional data sources.  Meanwhile, you can always chart how much data we have in an area by reviewing our data and accuracy table.
