You've found a $60,000 surplus lead in Harris County. The auction was 14 months ago. The deadline is in 10 months. The only thing standing between you and an $18,000 fee is one person — the former property owner — whose last known address is a house they no longer own. This is the actual job. Filing the claim is administrative. Finding the owner is where surplus recovery agents earn their cut.
Why Owner Location Is the Hardest Part
People who lose property to tax sales rarely announce where they went. Many moved under financial stress — eviction, divorce, job loss. Some are elderly and may have passed away. Some deliberately avoid their old address because of creditors. The county deed record shows who owned the property. It doesn't show where they are now.
The window matters too. Depending on the state, you may have 2–5 years from the date of sale before surplus escheats to the government. A lead sitting in your database that ages out without a located owner is pure lost revenue. Speed and systematic search methods are the difference between a closed case and an expired claim.
Step 1 — Start with County Clerk and Tax Assessor Records
Before paying for any skip tracing tool, exhaust free public records. The county deed record gives you the owner's name and the address of the property they lost — but it also often contains a mailing address from when property tax bills were sent. That mailing address may be different from the property address, and it's your first real skip tracing lead.
- County assessor's office — Mailing address on file for property tax bills. Often differs from the property address for investors and absentee owners.
- Deed records — The grantor/grantee index names all parties on recorded deeds. The original purchase deed may list a prior address.
- Voter registration records — Available in many states via public records requests. Often contains a current or recent residential address.
- UCC filings — If the former owner ran a business, their name may appear in state commercial filings with a current address.
Step 2 — Use Skip Tracing Databases
Skip tracing databases aggregate data from thousands of public and semi-public sources — credit header data, utility records, USPS address history, court filings, and more. For surplus recovery agents, three tools cover most searches:
TLO (TransUnion)
TLO is the professional-grade tool of choice for licensed investigators and legal professionals. It has the deepest data — utility connections, previous addresses going back decades, known associates, phone numbers tied to accounts. Access requires a legitimate business purpose, but surplus recovery qualifies. Expect to pay $1–3 per search. For high-value leads, this cost is trivial.
IRB Search
IRB Search is widely used in the surplus recovery community because it's accessible without the same vetting requirements as TLO. It pulls address history, phone records, and relative contacts. It's less deep than TLO but sufficient for most searches — and faster to get started with.
BeenVerified and Spokeo
Consumer-grade tools like BeenVerified and Spokeo are useful for quick checks and confirming addresses found elsewhere. They're less reliable for hard-to-find subjects but cost under $30/month for unlimited searches. Good as a first pass before spending money on TLO or IRB.
Step 3 — Social Media and Open Web Searches
Don't underestimate social media for recently relocated owners. A 55-year-old former homeowner who doesn't appear in databases often has an active Facebook profile with their current city listed. Search the full name plus their last known city, and look for profile photos that match details from property records.
- Facebook — Best for older demographics (45+). Check "About" section for current city, employer, and phone number.
- LinkedIn — Useful for owners who ran a business. Current employer often includes a location.
- Google search — Name + previous address, name + city, name + former employer. Obituaries are especially useful when searching for deceased owners.
- Court records — If the owner was involved in divorce, bankruptcy, or any civil suit after the tax sale, those filings often contain a current address. PACER covers federal courts; state court portals vary.
Step 4 — Heir Search for Deceased Owners
A significant percentage of surplus leads — especially on older properties — involve owners who have passed away. This doesn't kill the claim. It changes the process.
Surviving heirs can file surplus claims on behalf of the estate. Your job becomes locating and contacting the heirs, verifying their relationship to the deceased, and ensuring the claim is filed with the right documentation.
- Obituaries — Often list surviving family members by name. Search the owner's name + "obituary" to confirm death and identify heirs.
- Probate court records — If an estate was opened, probate filings list the executor and heirs by name. Most county probate indices are searchable online.
- Social Security Death Index (SSDI) — Confirms date of death and last known state of residence for U.S. citizens. Freely available through genealogy sites.
- Ancestry.com and FamilySearch — For older cases, genealogy databases can identify children, siblings, and other heirs when probate records don't exist.
Once you locate heirs, your claim must include documentation of the original owner's death (certified death certificate) and the heir's relationship to the estate. Some counties require a full probate proceeding; others accept a simple affidavit of heirship. Verify the county's requirements before proceeding.
Common Skip Tracing Pitfalls
Outdated Addresses
Database addresses can be years old. Before sending a certified letter, run an NCOA (National Change of Address) check via USPS or a mail processing service. An undelivered letter wastes time — and tips off the owner that someone is looking before you've made contact.
Identity Verification
When you find someone with the right name and approximate age, confirm they're the right person before sending paperwork. Ask for the last four digits of their SSN, their prior property address, or a description of the tax sale. Sending a fee agreement to the wrong person — or to a relative who isn't entitled to the funds — creates legal problems and kills the claim.
Multiple Owners on the Deed
If two people were on the original deed — spouses, business partners, co-owners — both must be located and sign the fee agreement. Missing one owner invalidates the claim in most jurisdictions. Always check the deed for all grantee names before you start your search.
Post-Sale Transfers
In some cases, the former owner transferred or sold the property before it was seized — which means a different party may have a superior claim to the surplus. Check the full chain of title in the county deed index before investing significant time in a lead.
How SurplusAI Handles Owner Research
Manual skip tracing works when you're running 5–10 cases. At 30+ active leads, the research workload becomes the bottleneck. SurplusAI automates the initial owner research step — pulling mailing addresses from tax assessor records, flagging leads where the owner is likely deceased, and identifying cases where multiple parties may have claims.
The AI document generator handles outreach once you locate the owner: one click generates a personalized contact letter, a follow-up, and a fully formatted fee agreement — pre-populated with the lead's details and the correct state-specific language. The paperwork takes minutes instead of hours.
