MNProperty records, with sources

What's publicly knowable about a property?

Terdaq answers three questions for any parcel: what is publicly knowable about it, what changed, and what that means. Sourced, not guessed. Minnesota first.

01What it shows

Tap a parcel. Read its public record.

Or search by address, PIN, city, ZIP code or county.

Where does that come from?

The source and freshness of every fact

No scraped listings, no crowdsourced guesses. When a fact is missing, Terdaq says why.

What's on the land?

Flood, wetlands, soils and water

FEMA flood zones, National Wetlands Inventory, USDA-NRCS soils, DNR public waters, MDH water wells, and terrain.

Who owns it?

Owner and taxpayer

As the county publishes them. Owner pages list every property an owner holds, with totals.

What is it worth?

Value, tax and history

Estimated market value, property tax, acreage and land use, with sale, tax and value history.

Can I use it out there?

Terdaq is built by GraniteCore Technologies, a private company. It is not a government app, and it is not affiliated with, endorsed by or operated by any government agency. Public records can be out of date or wrong. Terdaq is not a survey, a title search, an appraisal, a wetland delineation or an official flood determination; check with the office that publishes a record before relying on it.
