Set up trust accounting before you collect a second owner's guest payouts and you'll know, on any day, whose money is in your bank account, as long as you keep the records current. Trust accounting keeps money you hold for someone else separate from your own. Each owner gets a ledger, and every month you check that the bank, your books and those ledgers agree.
For a short-term rental co-host or manager, money held for others can include owner proceeds, repair reserves, pass-through cleaning charges and guest deposits held until a stay is settled. In some states a licensed broker who manages property must keep it in a designated trust account. In others the law may not reach you at all, but the owner's money is still not yours to spend, and mixing it with your operating cash is how small management businesses lose track of it.
I've spent 18+ years in real estate and have focused on short-term rentals since 2016.
Consider an operator who takes on two or three owner properties as a favor that turns into a business. Payouts land alongside their own rental income. The cleaner gets paid from whatever balance is there. At month end, nobody can say with confidence what the owner is owed.
Nothing was stolen. The money was never kept apart.
Below: state rules, a one-month owner ledger, a five-step setup and the monthly three-way check. This is an operator's playbook and does not replace legal or accounting advice. Confirm your state's rules with your real estate commission and a CPA.
What Trust Accounting Means for an STR Manager
The legal idea underneath trust accounting is simple. Wikipedia's article on commingling describes it as "a breach of trust in which a fiduciary mixes funds held in care for a client with their own funds, making it difficult to determine which funds belong to the fiduciary and which belong to the client." The same article notes that similar rules apply to licensed real estate brokers who hold deposits as agents for clients.
When you manage someone else's rental, you are in that position the moment a guest payout that belongs to the owner reaches an account you control. Trust accounting answers three questions at any moment:
How much money do I hold in total for owners?
How much of it belongs to each owner, down to the dollar?
Which of my own fees have I earned and moved out, and which are still sitting in the account?
In practice you keep three records:
The bank account itself.
A trust journal recording every deposit and payment in that account.
One sub-ledger per owner showing that owner's money in, money out and balance.
If the three disagree and you can't explain why, find the cause that month instead of at tax time.
If you are still deciding whether to take on owner properties at all, my comparison of DIY versus hiring out STR property management covers the workload side. This article assumes you have already said yes.
When Your State Requires a Trust Account
Whether you need a designated trust account depends on your state and on whether your management work falls under its real estate license law. That varies widely, and I'd treat everything below as examples to check against your own state's rules, not a national standard.
Arizona. Arizona Revised Statutes section 32-2174 says all property management accounts "shall be designated as trust accounts on the broker's records," and that a broker's trust account is required for all of the owner's monies unless the owner directs the broker to deposit them directly into the owner's account, in which case the broker shall not have access to that account. Money not subject to dispute or contingency must be deposited within three banking days of receipt.
Texas. The Texas Real Estate Commission rule at 22 Texas Administrative Code section 535.146 defines trust money to include rent, unearned fees, security deposits "or any money held on behalf of another person." A broker must deposit it in a trust account or deliver it to an authorized escrow agent by the close of business of the second working day after receipt, unless the principals expressly agree to a different time in writing. The broker may not commingle it with personal or operating money, must provide an accounting to each beneficiary at least monthly if the account had activity, and must remove money the broker has earned, such as fees, within 30 days.
Florida. Florida's broker license law has an exemption that matters to vacation rental managers. Florida Statutes section 475.011(11) exempts anyone who, for another and for compensation, "rents or advertises for rent, for transient occupancy, any public lodging establishment licensed under chapter 509." If the property you manage holds that license, broker trust account rules under chapter 475 may not apply to you, but check your situation with the state before you rely on that.
State | Due | Key rule |
|---|
AZ | 3 bank days | Trust acct |
TX | 2nd work day | Mo. report |
FL | Check | Ch. 509 exempt |
The table is a summary. Arizona's deadline covers money not in dispute or contingent, Texas allows a different deposit time if the principals agree in writing, and Florida's exemption covers only the activity the statute describes.
Even if broker trust account rules do not apply to your activities, check what your management agreement says about handling funds. In my experience the owners who stay longest are the ones who get a clean monthly statement, and keeping their money separate makes that statement far easier to produce. Keep each owner's ledger current and you'll be able to show what you owe and how you calculated it.

Where Owner Money Gets Mixed Up in an STR Business
An STR manager may handle several kinds of money in and out. Map each one before deciding how to record it.
Guest payouts. If payout settings route owner proceeds to an account you control, you are holding money that must be tracked for the owner.
Cleaning fees. If a payout includes a cleaning charge you pass through to the cleaner, track the receipt and the payment separately, and confirm its treatment under the agreement and with your accountant.
Owner reserves. If you hold a repair or supply reserve for an owner, record it as owner money held for the agreed purpose.
Direct-booking deposits. Damage deposits and advance payments from your own booking site are held for the guest or the owner under the terms of the booking until the stay is settled.
Your fee. Once you earn it, transfer it out of the trust account on a set schedule.
Airbnb's own help article on co-hosting tells hosts and co-hosts to be clear about who does what, "how much of the reservation income goes to the co-host," and how the co-host will be reimbursed for expenses. Those agreements tell you how to record income, fees and expense reimbursements. My guide to the co-host agreement and what your percentage is really a percent of covers how to define the fee base so the ledger has a rule to follow.
The simplest structure keeps owner money out of your hands entirely: payouts go straight to the owner and the owner pays your invoice. Arizona's statute names that option, so it is a recognized model. The trade-off is control, because you then depend on the owner to fund cleaners and repairs on time.
One Owner, One Month: The Ledger in Practice
Here is one owner's month on a 20% management fee charged on payouts after cleaning. The figures in this article, tables and prose examples, are illustrative only and not drawn from a real client.
Line | In | Out | Left |
|---|
Payout | $6.2k | | $6.2k |
Cleans | | $1.1k | $5.1k |
Fee 20% | | $1.0k | $4.1k |
Repair | | $0.3k | $3.8k |
Owner | | $3.8k | $0 |
Read it top to bottom. $6,200 of guest payouts arrive. $1,100 goes to the cleaners. Your 20% fee on the remaining $5,100 is $1,020, shown rounded as $1.0k. A $300 repair is paid from the owner's money with a receipt attached. The owner receives the rest, roughly $3,780, and the sub-ledger ends the month at zero, or at the agreed reserve if you hold one.
Two habits make this work:
Back every line with a document: the payout report, the cleaner's invoice, the repair receipt and your fee calculation.
Transfer your fee to your operating account as its own transfer, on the day you earn it or on a fixed date each month.
Texas requires brokers to remove money they have earned from the trust account within 30 days. In any state, fees left mixed with owner balances make the next reconciliation harder.
Trust Accounting Setup: A Five-Step Process
This is the order I'd use to set up trust accounting for a co-hosting or management business, from the first owner to the tenth.
Step 1 — Confirm what your state requires
Look up whether your management activity needs a real estate license in your state and, if it does, the commission's trust account rules: deposit deadlines, account naming, who may sign and how often owners must get statements. Arizona and Texas, above, show how specific those rules get.
Step 2 — Open a separate account titled as a trust or escrow account
Open a dedicated account for money you hold for owners and other beneficiaries, following your state's account and titling rules. Texas requires the account to be "clearly identified as a trust account." Never route your own rental income or business expenses through it.
Step 3 — Create one sub-ledger per owner
In your accounting software or a spreadsheet, give each owner a ledger with date, description, money in, money out and running balance. Allocate each transaction to the right owner or guest ledger, split pooled transactions such as a bank deposit covering several payouts, and track any balance your state permits you to keep there on its own line.
Step 4 — Set the fee and disbursement schedule in writing
Put in the management agreement when you calculate your fee, when it moves to your operating account and on which day owners are paid. A fixed monthly date, for example the 10th, gives you time to receive the last payouts of the month and finish the reconciliation first.
Step 5 — Reconcile every month before you pay anyone
Before owner distributions go out, run the three-way reconciliation in the next section. If it does not balance, investigate that day and get accounting or legal guidance before making any affected payment, while still meeting the payment terms in your agreements.
The Monthly Three-Way Reconciliation
A three-way reconciliation compares three totals at the same date: the bank balance adjusted for items in transit, the balance in your trust journal and the sum of every owner, guest and other beneficiary sub-ledger. Once timing items and any balance your state permits you to keep are accounted for, all three should agree. Here is an illustrative month-end for a manager with three owners and no other balances.
Check | Total | Status |
|---|
Bank | $14.6k | Adj. |
Book | $14.6k | Match |
Owners | $14.2k | Short |
Gap | $0.4k | Fee |
The bank and the journal agree, but the owner ledgers add up to $400 less. In this illustration, assume the records show the $400 is fees you earned and charged to each owner's ledger but never transferred out. Move it to operating within your state's deadline and record the transfer. A gap alone doesn't prove its cause: Texas, for example, gives brokers up to 30 days to remove earned money and allows a documented reasonable balance for bank service fees.
Other gaps run the opposite way, with the owner ledgers totaling more than the bank. You may have paid an expense from the trust account without charging it to an owner, or used owner money for something that was not theirs. Find that one fast.
Keep each month's reconciliation with its bank statement and owner statements. Texas requires a documentary record of every deposit and withdrawal; even where no rule requires it, that file is what protects you if an owner disputes a statement.
Mistakes That Turn Into Commingling
Paying a business bill from the trust account. Texas lists paying operating expenses from a trust account as prima facie evidence of commingling. Pay software, insurance and payroll from operating only.
Fronting one owner's repair with another owner's balance. The account total may cover it, but that owner's ledger cannot go negative. Pay from operating and bill the owner instead.
Letting payouts land in your personal account. If your platform payout method is your personal checking account, change it before the next owner joins.
Holding fees "for later." Move earned fees out on schedule. Texas sets a 30-day limit for brokers.
Skipping a month. In my experience a gap is easy to find after one month and very hard after six.
If you are building toward a bigger team, my post on who to hire and when as an STR business grows covers where a bookkeeper fits. Monthly trust reconciliation is a good first task to hand off, as long as you still review the result.
Frequently Asked Questions
What is trust accounting?
Trust accounting is the bookkeeping for money you hold on behalf of someone else. It keeps that money in a separate account, tracks each person's share in its own ledger and proves monthly that the bank, the books and the ledgers agree.
Do Airbnb co-hosts need a trust account?
It depends on your state and on whether your work falls under its real estate license law. Arizona requires a broker's trust account for owner money unless the owner has it deposited into the owner's own account, which the broker cannot access. Texas requires brokers to keep trust money in a designated trust account or with an authorized escrow agent. Florida's section 475.011(11) exempts certain transient rentals of chapter 509 licensed lodging, so confirm whether your activities qualify.
What is a three-way reconciliation?
It compares the adjusted bank balance, your trust journal balance and the total of all owner, guest and other beneficiary sub-ledgers at the same date. All three should agree once timing items and permitted balances are included; investigate any difference you can't explain.
Can I keep my management fee in the trust account?
You should move earned fees out on a schedule. Texas requires brokers to remove money they have earned from the trust account within 30 days, and fees left in trust make the monthly reconciliation harder to read.
What happens if I commingle owner funds?
Commingling makes it hard to show which money belongs to whom. For licensed brokers it can lead to discipline by the state commission, and for any manager it weakens your position if an owner disputes a statement.
