A customer visiting multiple branches of the MSB on the same day in order to transfer funds internationally is a potential indicator of structuring, which is a technique used by money launderers to avoid reporting thresholds or detection by authorities. A customer attempting to buy money orders under $3,000 USD in cash multiple times a day is also apossible sign of structuring, as well as an attempt to evade the identification and recordkeeping requirements for MSBs. Both scenarios should be included in the procedures for further review by the AML Officer.
BSA/AML Risk Assessment for Money Services Businesses (MSBs), section "Risk Factors", sub-section
"Structuring": "Structuring is the practice of conducting financial transactions in a specific pattern calculated to avoid the creation of certain records and reports required by the BSA and/or 31 CFR Chapter X.
Structuring is illegal and is often indicative of money laundering or other illicit activity." Money Services Business (MSB) - AML Compliance Guide, section "AML Compliance Requirements for MSBs", sub-section "Identification and Recordkeeping": "MSBs must verify the identity of any person who conducts a transaction of $3,000 or more. They must also keep records of the transaction, including the name, address, date of birth, and identification number of the customer, as well as the amount, date, and method of payment."

The Board of Directors is the primary governing body of a financial institution and has the fiduciary duty to oversee and approve the BSA/AML compliance program. One of the key responsibilities of the Board is to ensure the appointment of a qualified chief AML officer who has the authority, expertise, and resources to implement and manage the BSA/AML program effectively. The chief AML officer is accountable to the Board and senior management for the performance of the BSA/AML program and should report regularly on the status, issues, and challenges of the program. The Board should also evaluate the chief AML officer's performance and provide feedback and guidance as needed.

This is a common red flag of money laundering that involves layering, which is the process of moving funds through multiple accounts or entities to conceal their origin and ownership. Layering often involves cross- border transfers, especially to high-risk jurisdictions, and rapid movement of funds to avoid detection or tracing. A compliance officer should prioritize this red flag for investigation, as it may indicate a complex money laundering scheme or the financing of terrorism or proliferation.

Structuring is the intentional evasion of a reporting or recordkeeping requirement by breaking down a large transaction into smaller ones, or by using multiple accounts, institutions, or persons to avoid triggering the threshold for reporting or recordkeeping. Structuring is also known as smurfing, and it is a common technique used by money launderers to conceal the source, ownership, or control of illicit funds.

The scenario described in the question presents several indicators of potential money laundering through real estate, which the broker should be aware of and report accordingly. The most relevant red flags are:
Value: The student wants to buy a home that is overvalued, meaning that the asking price is higher than the market value or the appraisal value of the property. This could indicate that the student is trying to launder a large amount of illicit funds in one transaction, or that the seller is colluding with the student to inflate the price and receive a kickback. Overvaluing or undervaluing properties is a common technique used by money launderers to manipulate the price of real estate and conceal the source or destination of their funds12.
Inconsistency: The student's behavior and profile are inconsistent with the typical characteristics of a legitimate home buyer. The student cancels the viewing of the home at the last minute due to illness, which could suggest a lack of interest or a pretext to avoid scrutiny. The student also wants to buy an expensive home despite being a student, which could indicate a discrepancy between the student's income and the source of funds. Moreover, the student disregards the broker's objections to the asking price, which could imply that the student is not concerned about the value or quality of the property, but rather the amount of money that can be laundered through it34.
Transaction speed: The student wants to quickly buy the home, which could indicate a sense of urgency or pressure to move the illicit funds before they are detected or seized by the authorities. Money launderers often use fast transactions to avoid raising suspicion or leaving a paper trail. Transaction speed is especially relevant when combined with other red flags, such as cash payments, anonymous buyers, or overvalued properties5 .
