Residential Sales Search

Compare recent sales to your property

The Naperville Township Assessor Office provides sales data imported from DuPage County real estate transactions. This sales data provides property owners with a means to compare his or her assessed market value to similar properties that have recently sold on the open market. Statutorily, the comparables sales should be taken from within three years prior to the assessment date (for example: if the assessment date is January 1st, 2023, then sales should be from 2022, 2021, and 2020). Our sales search system will automatically provide only sales from within the correct period of time, properties that are within your neighborhood, and homes that are similar.

Searches can ONLY be conducted by Property Index Number (PIN). If you do not know your PIN, then please first search by address here or consult a previous tax bill or Assessment Notice.
