Commingling in Property Management: What STR Managers Must Avoid
Commingling happens when client funds and company funds are mixed. See where STR property managers face the greatest risk and how clear workflows help prevent it.
The definition
What is commingling in property management?
Commingling is the mixing of money belonging to owners, guests, tenants, or other clients with the property management company’s own operating funds. It can happen through deposits into the wrong account, unsupported transfers, personal or company expenses paid from trust, or excess company money left in a client account.
Rules differ by jurisdiction, including whether a limited amount of broker funds may be held to cover bank charges. The core principle is consistent: client money must remain identifiable and protected, and the manager should be able to demonstrate which funds belong to the business and which are held for others.

How STR property managers can prevent commingling
STR payment flows make accidental commingling easy. A booking platform may send one net payout containing rent, a cleaning fee, tax, and the manager’s commission. If the whole deposit is recorded as revenue or swept into operating cash, the books can lose the distinction between client liability and earned company income.
Prevention starts with account architecture. Use clearly named bank accounts, map platform payouts to clearing accounts, and define when management fees are considered earned under each contract. Transfers from trust should be supported by an owner statement, invoice, reservation record, or other approval that shows the amount and purpose. Avoid using trust as a temporary source of working capital, even when the plan is to replace the money quickly.
Add separation of duties wherever the team allows. The person initiating a transfer should not be the only person approving it, and monthly reconciliation should be reviewed by someone accountable for the trust function. These controls create a visible trail and turn commingling prevention into a routine process rather than a last-minute compliance exercise.
Practical checklist
- Use distinct trust and operating bank accounts
- Define when fees are earned before transferring them
- Match net platform payouts to their gross components
- Require support and approval for every trust-to-operating transfer
