CoreLogic's ListSource builds broad national mailing lists. PropScored scrapes county filings daily and sells them exclusively by zip code. Here's the honest breakdown.
ListSource, built on CoreLogic's national property database, is a self-serve tool for pulling broad homeowner and demographic mailing lists across almost any U.S. market. PropScored is a narrower, real-estate-specific service that scrapes 11 distress signal types daily across 15+ Georgia and Florida counties and sells them exclusively by zip code, with motivation confirmed by an actual public-record filing.
Credit where it's due: ListSource's core pitch is legitimate. It sits on top of CoreLogic's property database, which the company says covers 94% of all property owners in the U.S., and its own site states the underlying data is updated daily. That's a real, useful foundation. ListSource also isn't a one-vertical tool — it serves academic institutions, government and utilities, insurance, mortgage, title & settlement, non-profits, and residential real estate, with quick lists for absentee owners, FHA/VA eligibility, first-time buyers, foreclosure, reverse mortgage prospects, and new movers. If you need a self-serve, national, low-friction way to pull a categorical list — say, every absentee owner in a metro area — ListSource is a reasonable, established option.
The gap is what a "lead" actually represents. ListSource segments homeowners into categories — absentee, first-time buyer, foreclosure, reverse mortgage — built from database attributes. That's a prospect classification, not a confirmed event. There's nothing on ListSource's site suggesting a given list is sold to only one buyer, which matters if you're farming the same distress category as every other investor and agent pulling the same list in your county. PropScored takes the opposite approach: each lead traces back to a real county filing (a lien, a pre-foreclosure notice, a probate record) and is sold to exactly one agent per zip code.
| Dimension | ListSource | PropScored |
|---|---|---|
| Data source | CoreLogic national database (94% of owners) | 11 distress signals, daily county scrapes |
| Freshness | Database "updated daily" (record currency, not lead-to-you speed) | Median 2 days filing-to-lead across 1,142 filings |
| Exclusivity | Not stated — lists can be repurchased by others | Exclusive by zip code, one agent |
| Contact data | Match rates not published | 84% verified phone/email, 5,265 prospects |
| Motivation signal | Categorical (absentee, foreclosure, etc.) | Confirmed by an actual public-record filing |
| Best for | Broad, multi-vertical national mailing lists | Exclusive, verified distress leads in GA/FL |
ListSource's static ATTOM lists age the moment you download them—a problem HBR research quantifies: leads contacted within an hour are ~7x more likely to qualify than those contacted an hour later. PropScored scrapes daily, delivering a median 2-day lag from filing to lead, with bankruptcy signals arriving in just 1 day. HBR's landmark study shows the competitive edge goes to agents who react fastest to real events—not batch downloads that sit dormant for weeks.
ListSource's site states its data is updated daily — a fair and believable claim for a database of this size. But that's a statement about record currency, not about how quickly a specific distress event reaches a subscriber's inbox. PropScored tracks the second number directly: a median of 2 days from public-record filing to a sourced lead, measured across 1,142 timestamped filings, with bankruptcy filings surfacing in about 1 day, pre-foreclosure in about 3, and liens in about 7 (county lien lists arrive as periodic bulk loads rather than daily feeds — the one exception). For more on how that lag is measured, see our data freshness breakdown. Most batch-built prospecting platforms recalculate on 30–90 day cycles — a gap discussed at length in this thread on PropStream alternatives.
ListSource sells property and ownership records; its site doesn't publish a phone or email match rate, so it's hard to say how contactable a given list is out of the box. PropScored reports this directly: across 5,265 sourced prospects, 84% carry a verified phone or email (69% phone, 64% email), with source-level rates as high as 97% for liens and 96% for FSBO. Agents who'd rather not dial cold themselves can also add PropScored's done-for-you outreach on top of the same leads.
Honestly, plenty of people. If you're marketing outside real estate — insurance, home improvement, non-profit fundraising, government outreach — or you need a national, self-serve list across states PropScored doesn't cover yet, ListSource's breadth (built on CoreLogic's database) is a legitimate fit. It's also a reasonable choice for agents doing broad geographic farming who don't need county-verified distress signals or exclusivity.
If you're an agent or investor working Georgia or Florida and want distressed seller leads that are county-verified, exclusive to your zip code, and confirmed by a real filing rather than a demographic guess — that's the gap PropScored is built to close. Pilots start at $500 for 60 days, with standard plans from $200/month.
