ListSource

What Is ListSource?

ListSource is a property owner data platform owned by CoreLogic, one of the largest real estate data companies in the country. The platform covers approximately 94% of all U.S. property owners with daily data updates, making it a go-to source for wholesalers who need accurate, current ownership lists.

The core use case is list-building for direct mail campaigns. You filter by property characteristics (property type, equity position, mortgage status, owner-occupancy, geographic area) and purchase a targeted list of property owners. Pricing is pay-per-record, so you only pay for the contacts you actually download.

ListSource also offers pre-built "Quick Lists" for common investor segments — absentee owners, foreclosure prospects, new homeowners, and reverse mortgage candidates — which speed up list-building for wholesalers who already know their target profile.

Who Is ListSource Best For?

ListSource is best for wholesalers who run direct mail campaigns and need a reliable, broad-coverage data source for building targeted prospect lists. The CoreLogic data foundation means you're pulling from one of the most authoritative property databases in the U.S.

It's a solid choice for investors targeting specific niches: absentee owners, out-of-state owners, high-equity homeowners, or pre-foreclosure prospects. The filtering tools are straightforward and don't require API skills.

If you also need phone numbers or email addresses for cold calling or texting, you'll need to skip trace the list separately — ListSource is primarily a mailing address data source.

Our Verdict

ListSource delivers what it promises: broad, accurate U.S. property owner data with solid filtering for direct mail targeting. The CoreLogic backing means data quality and update frequency are genuinely reliable.

The per-record pricing model works well for occasional list pulls but can add up for high-volume campaigns. The platform doesn't include phone numbers or email addresses natively, so budget for a separate skip trace step if your outreach strategy goes beyond physical mail.
