Data Enrichment for Pre-Listing Leads: From a Name in a Filing to an Actionable Conversation

A probate filing typically contains the decedent’s name, the date of death, the county, and the petitioner’s name. Useful as a triggering signal. Useless on its own. The actionable lead — an heir at a current mailing address with an equity estimate and a mortgage balance — lives downstream of a five-stage enrichment pipeline. This piece walks through what each stage actually does.

What the raw signal actually contains

The raw filing has the decedent’s legal name, often misspelled relative to other public records. It has the date of death. It has the petitioner’s name (often an adult child) and address (often a PO Box or an attorney’s office). It has the court case number and the assigned judge. It does not have property addresses, equity positions, mortgage balances, or current contact information for the heir.

Mailing the raw filing as-is sends pieces to the petitioner address listed in court, which is frequently an attorney or a PO Box. The actual heir who is deciding what to do with the home is in another state, at an address the filing never specified.

Stage 1: tie the decedent to a specific property

Cross-reference the decedent’s name against county tax-assessor records. Most states publish the assessor roll with current owner of record, property address, and legal description. A name match (handling middle initials, spelling variants, and previous addresses) produces the candidate property.

Edge cases: decedents who owned multiple properties, decedents whose name appears with spouse or co-owner, decedents whose last legal residence was different from the property in question. The enrichment pipeline handles these by checking deed history and by prioritizing the homestead property (the one with the homestead exemption).

Stage 2: pull the mortgage and equity position

Pull the current deed of trust (or mortgage) from county recorder records. Original loan amount, origination date, lender. Check for subsequent reconveyances (loan paid off) and subsequent encumbrances (HELOC, second mortgage). Estimate current balance from amortization plus any modifications.

Pair this with a property-value estimate (recent comparable sales plus assessor market value). Subtract estimated mortgage balance from estimated property value: the rough equity position. For inherited homes, this number is typically 65-80% per our piece on inherited home equity.

Stage 3: resolve the executor or beneficiary

The petitioner named in the filing is the candidate. The pipeline cross-references the petitioner against voter rolls, social signals, and skip-trace data to confirm identity and produce a current contact. For petitioners who are attorneys (common in larger estates), the pipeline then resolves the actual beneficiaries from the estate inventory or the will, where filed.

Where multiple heirs exist (common in inherited homes), the pipeline ranks them by likely decision authority. Surviving spouse first. Eldest child second. The decision-maker is rarely the entire heir group; it is typically one or two people who the rest defer to.

Stage 4: confirm a deliverable mailing address

The resolved heir contact is run against NCOA (National Change of Address) to check for recent moves. The address is validated against USPS deliverability standards. PO Boxes are accepted but flagged. Addresses where the heir co-habits with another person who has opted out of mail are deprioritized.

For heirs who live in a different state than the property (which is the majority of cases), the mailing goes to the heir’s home state, not to the property address. A common failure mode of cheaper data products is mailing the property address itself, which sends the piece to a vacant house.

Stage 5: final eligibility checks

Trust check: does the property’s deed vest in a trust? If so, eliminate.

TOD check: is there a recorded transfer-on-death deed against the property? If so, eliminate (and check for revocation).

MLS check: is the property currently listed? If so, eliminate.

Investor-sale check: has the property recently transferred to a wholesaler or cash buyer entity? If so, eliminate.

Why enrichment is most of the cost of the channel

The triggering signal is essentially free. Probate filings, obituaries, and deeds are public. The enrichment is what costs money. Cross-referencing decedents to tax records, pulling deed histories, calculating equity, resolving heirs, validating addresses, and running eligibility checks — this is what the platform fee covers. The leads themselves cost a tiny fraction; the enrichment is the product.

Cheaper alternatives skip enrichment. They sell raw filing lists at a low per-lead price. The agent then either does the enrichment manually (impractical at scale) or skips it and mails the raw list (low conversion). Both paths produce the “I tried probate prospecting and it did not work” outcome.

Done well, enrichment is what turns a 0.5% raw-list conversion rate into a 6-8% enriched conversion rate. That is the structural reason the channel is worth running at all.
