Property Information

Property Information Lookup

The search is for Winnebago County properties and will only include City of Oshkosh, Neenah, Menasha, and Appleton properties if there is a delinquent tax balance. If you are looking for current ownership information for a city property you will need to access their website directly.

As of February 3, 2014, the property information website has changed. After going to the link, please update your bookmark or favorite for future references. The information and content remains the same, only the format has changed.

For best results when using this site, we recommend:

    Disable an pop-up blocking software
    Internet Explorer 9 or 10 or Google Chrome
    Acrobat Reader 9.0
