COMPER Property Search Tool
The Grand County Assessor’s office makes every effort to produce and publish the most current and accurate property information possible, including property sales. 2023 values will be available on COMPER after May 1, 2023.
As an ongoing commitment to the public to provide excellent service, we are introducing a high-tech tool (COMPER) to make this information conveniently accessible.
When the COMPER by Spatialest window opens, you can search property by entering either an Address, or Account Number.
- This will open the Comper site in a new window, displaying the subject parcel and all of the comparable sales in the area.
- You can narrow your search by changing the “REFINE BY’ criteria at the top of the page in order to find similar houses in the area. (The sales date has been preset to the mandatory time period (24 month) set by the State for determining current values.)
- Once you have selected your comparable properties, (by highlighting ‘add comp’) click on “Save Comparables (PDF)” in red at top of page to save a PDF file of your selections, which can be used in your review.
- To remove a comparable from your list, click ‘comparable’ on the property you want to remove and then click ‘save my Comparables’ again to get an updated PDF
