Which method could be used in the placement stage of money laundering in the real...

Money laundering typically occurs in three stages: placement, layering, and integration. The placement stage involves introducing illicit funds into the financial system.

In the real estate sector, using cash to purchase property is a classic placement method. Cash payments allow criminals to inject large amounts of illicit proceeds directly into high-value assets, often bypassing traditional banking scrutiny.

Using trusts to transfer ownership and rapidly reselling property are more commonly associated with layering or integration, where ownership and transaction complexity is used to disguise the origin of funds. Paying routine invoices via online banking is consistent with legitimate business activity and does not represent placement.

Therefore, cash purchases of property most directly align with the placement stage of money laundering.
