RadiusMapperParcel and owner data
Every parcel. Every owner.
Property owner search that starts with a click on the map
Click a lot and the owner, their mailing address and what they paid are right there. Drag across a block and you have every owner on the street.
Overview
From a lot to its owner in one click
Finding the owner of a lot usually means going between the assessor's site, the recorder's site and a people-search tab to work out who owns it and where they live. For a whole block, that can take a day.
Here you click the lot. The owner's name, land use, assessed value, acres and APN come up right away. If it looks promising, open the full record and you'll see where the owner gets their mail, how long they've held it, what they paid, what they still owe and whether anything is in distress.
For a whole block, shift-drag across it. Every owner comes along, ready to enrich in one step and mail from the same screen. If a parcel has nothing more on file, the record says so.
Click any lot
See Who Owns It Without Leaving the Map
Turn on parcels, zoom to the street and click. The record opens beside the map with the owner of record, land use, assessed value, acreage and APN. Condos and other stacked parcels page through one at a time, so you never guess which unit you're looking at.
- Owner, use, value, acres and APN on the first click
- Parcel lines across the US, drawn at street level
- Stacked parcels page through one by one

Use Cases
How People Put Owner Data to Work
Assembling three lots for a townhome project
You need three adjoining lots to make a townhome plan work. If one owner won't talk or is already under contract, the deal doesn't pencil, so you want to know who you're dealing with before anyone else does.
Result: Three owners, where they get their mail, how long they've held and what they owe, before your first call.
Building an absentee owner list for a rental acquisition fund
You want single-family rentals whose owners live out of state, the ones most likely to sell quietly. A bought list is full of owners who live in the house.
Result: A short list of out-of-state owners with their equity and the area's fair market rent, built from houses you picked.
Checking ownership before a cell tower lease call
You have a search ring and two candidate parcels at the edge of town. Before you call anyone, you need to know who owns them, whether that's a person, a company or a trust, and whether anything messy is on record.
Result: The owner of record and a mailing address for each candidate, with any liens, notices or recent transfers flagged.
Pricing a retail pad against nearby sales
You're walking into a listing pitch on a retail pad tomorrow. You want to know what the owner paid, what they owe and how the assessor sees it before you name a number.
Result: Purchase history, values and nearby comps in one place, so your number holds up in the room.

Common Questions
How do I find out who owns a property?
Turn on the parcel layer, zoom in to street level and click the lot. The owner of record shows up right away. If you need to reach them, the full record adds their mailing address, what kind of owner they are and how long they've held it.
Can I see what other properties an owner has?
Yes. The Overview tab in the full record shows the owner's portfolio: how many properties they hold, the combined value, equity and debt, and how many they've bought in the last 6 and 12 months. It's a quick read on whether you're talking to a homeowner or an investor.
Where does the parcel and owner data come from?
Parcel lines and the basic fields come from county assessor and parcel records. Full records pull assessor, deed, mortgage and listing records into one view. Where we hold the county's own records, you see those first.
How accurate are the property lines on the map?
They're drawn from county parcel records, which are built for tax assessment, not surveying. They're right for working out which lot is which and who owns it. If a few feet matter, get a licensed survey.
Can I look up every owner on a street at once?
Yes. Shift-click lots or shift-drag across the area, then hit Enrich. Every owner in the selection comes back with a name and mailing address, records you've already opened are skipped, and parcels with nothing on file are counted so you know where the gaps are.
Can I tell if a property is in foreclosure?
Yes. The full record flags pre-foreclosure, auction, bank-owned, tax liens, liens and judgments right under the owner's name. The Financials tab lists foreclosure filings with details like the opening bid and default amount when they're on record.
