Methodology

How HFD Scan works — and what it does not do

Our screens look for documented characteristics commonly observed in real-estate scam attempts. They do not determine whether a specific message, party, or transaction is fraudulent. This page explains exactly what we screen for, where those patterns come from, and what is outside the screen's scope.

1What HFD Scan does and does not do

HFD Scan screens submitted information — a message, a phone number, wire instructions, or a property address — for documented characteristics commonly observed in real-estate scam attempts.

HFD Scan does not determine whether a specific message, sender, or transaction is fraudulent. The presence of one or more documented characteristics does not establish that a message is fraudulent. The absence of such characteristics does not establish that a message is genuine. Always verify independently with the named entity using contact information you obtain from a source other than the message itself.

2Where the patterns come from

Our pattern catalogs draw on public guidance from U.S. federal consumer-protection agencies, state Attorneys General, and recognized consumer-advocacy organizations. We update this list as the cited sources update theirs.

3What each screen looks for

Pattern categories are listed below — not the exact detection rules. Specific rule definitions are intentionally withheld so they cannot be used as a checklist by bad actors to evade screening.

HFD Scan (message review)

  • Urgency and time-pressure cues ("act today," "final notice")
  • Out-of-band channel pressure ("don't call the office, text me here")
  • Sender / domain / display-name mismatch with the named entity
  • Unusual payment instrument or routing requests
  • Threats, consequences, or appeals to authority that bypass normal verification
  • Look-alike branding of well-known title companies, lenders, or government agencies
  • Requests for sensitive information (SSN, account numbers, deed details) outside an established channel

Wire verification

  • Wire instructions delivered through email rather than verified out-of-band
  • Last-minute changes to wire instructions before closing
  • Recipient bank or routing number that doesn't match the title company of record
  • Domain inconsistencies between the wire-instruction email and the title firm's known domain

Contact verification

  • Phone number registered to known VOIP / disposable-number ranges
  • Inconsistencies between caller's claimed entity and the entity's published contact details
  • Recently created contact records with no historical footprint

Property visibility

  • Public-records owner of record vs. submitted owner — match status
  • Recent ownership changes or deed transfers
  • Outstanding liens or encumbrances visible in county records
  • Listing presence across multiple platforms with inconsistent price, status, or contact info
  • Patterns associated with absentee-owner equity-stripping schemes

4AI vs. human review

HFD Scan results in this product are AI-generated. Each result is labeled as such on every result screen. Pattern matching is performed by a large language model against the documented pattern catalogs cited above. The AI does not reach a verdict — it lists which characteristics it observed.

A separate human-review path is available by emailing scan@homefrauddefense.org. Human review is performed by Home Fraud Defense™ staff and is also informational only — it does not constitute legal, financial, or investigative advice.

5What HFD Scan does not screen for

Setting the negative scope explicitly is part of our liability discipline. If you need any of the following, seek the appropriate licensed professional.

  • We do not check criminal records of any sender, agent, broker, or party.
  • We do not verify the identity of any individual.
  • We do not perform a title search or replace one. A title search by a licensed title company remains essential.
  • We do not provide legal, financial, or tax advice.
  • We do not contact, notify, or report to the named entity, sender, or any third party on your behalf.
  • We do not adjudicate disputes between parties to a transaction.
  • We do not guarantee that any message, party, or transaction is fraudulent or genuine.

6How to verify independently

No matter what an HFD Scan reports, the single most protective step you can take is to contact the named entity using a phone number or email you obtain from a source other than the message itself — for example, the title company's published main line, your lender's number from your loan documents, or the county recorder's official website.

If you have already sent funds to a fraudulent account, time is critical. Contact your bank immediately to request a wire recall, then report the incident:
