Anti-Money Laundering Rules for Mortgage Lenders in 2026: BSA, SAR Filing, and Compliance

The Bank Secrecy Act applies to mortgage companies, and MLOs working at non-depository lenders have compliance obligations that are often less understood than those at banks. FinCEN has increased oversight of real estate transactions, and the geographic targeting orders requiring cash transaction reporting in specific markets have expanded. MLOs need to understand what triggers an SAR, what CIP requires, and when a transaction raises enough flags to escalate.

Customer Identification Program Requirements

Every mortgage company that is a covered financial institution under the BSA must have a Customer Identification Program. At minimum, CIP requires verifying the borrower's name, date of birth, address, and government-issued ID. For entities like LLCs or trusts, beneficial ownership rules require identifying the natural persons who own or control the entity. Fannie Mae and Freddie Mac investor property loans increasingly involve LLC borrowers, and CIP for these files requires documentation beyond what a typical residential application provides.

Suspicious Activity Reporting

• ✦Mortgage companies must file SARs for transactions involving $5,000 or more where there is reason to suspect money laundering, structuring, or fraud
• ✦Common SAR triggers: large unexplained cash deposits used as down payment, third-party wire transfers with no documented relationship to the borrower, multiple refinances in a short period with equity extraction, and borrower identity inconsistencies
• ✦Straw buyer transactions -- where someone purchases on behalf of an undisclosed third party -- are both mortgage fraud and potential BSA violations
• ✦OFAC screening is required; borrowers must be checked against the SDN list before closing; most LOS systems run this automatically at application

FinCEN Geographic Targeting Orders

FinCEN has issued Geographic Targeting Orders requiring title insurance companies to report all-cash real estate transactions above certain thresholds in designated markets. These are not directly an MLO obligation but understanding them helps in markets where investor cash deals are common. If a borrower purchased a property in a GTO-covered market within the last 12 months, the title company may have already reported that transaction to FinCEN.
