Cash Sweep

How a cash sweep works

A commercial mortgage is usually secured by two things: the property and the income it produces. A cash sweep gives the lender a claim on the second one before it becomes a problem. When a performance test fails, the lender takes control of the property's cash flow and stops the owner from distributing the surplus.

The mechanics have three parts:

1. A deposit account. Tenants pay rent into an account in the lender's name or under its control. This is the lockbox, and it is the pipe that makes a sweep possible.
2. A waterfall. Under a cash management agreement, every deposit is paid out in a set order: taxes and insurance, operating expenses, debt service, required reserves, and finally the surplus.
3. A trigger. If the test is passed, the surplus goes to the borrower. If it is failed, the surplus is held in a lender-controlled account instead, and it stays there until the loan documents say it can be released.

Excess cash flow = Property income − operating expenses − debt service − required reserves

The excess is the money an owner would otherwise treat as profit: the distribution to investors, the money for the next acquisition, or the repair budget that was not funded by the lender. A sweep takes that away until the lender is satisfied.

Sweeps are most visible in CMBS loans, where a servicer administers the loan on behalf of bond investors, and in bridge and other transitional loans where the property is not yet at stabilized income. Banks and other portfolio lenders use the same idea in different clothes, usually as a financial covenant plus a requirement to keep deposits at the bank.

Cash sweep vs. cash trap vs. cash management

These terms are used loosely, and the loan agreement is the only definition that matters. The distinctions you will most often meet:

• Cash management is the whole system: the accounts, the waterfall, and who controls them. It can run in the background for the life of the loan.
• A cash trap usually means surplus cash is held in a lender-controlled account and can come back to the borrower when the trigger is cured.
• A cash sweep in the narrow sense may go further: the swept cash can be applied to the loan balance, or held as additional collateral until payoff. In common speech, "sweep" covers both.

The practical question is not which word the term sheet uses but what happens to the money: where it sits, who can spend it, what it can be spent on, and what ends the trap.

Do not confuse a loan cash sweep with a bank sweep account, which is a deposit product that moves idle balances into an interest-bearing account overnight. Same word, unrelated purpose. A corporate-finance "cash sweep" that applies excess cash to a term loan each year is closer to the loan provision here, but in real estate it is tied to a property-level test.

Springing, hard and soft structures

The strength of a sweep depends on how the lockbox is set up, because that decides who touches the cash first.

Structure	Who controls rent day to day	When the lender takes over
Hard	The lender. Tenants pay straight into the lender-controlled account.	From closing. Surplus is released to the owner only if the loan allows it.
Soft	The borrower. Tenants pay into an account the borrower manages and then moves the funds.	Only when the lender activates cash management, often after a default or trigger.
Springing	The borrower, until a trigger.	When a trigger occurs, the account is converted to a hard lockbox and the sweep starts.

Springing structures are the usual compromise on stabilized properties: the borrower runs the property normally while the numbers are good, and the lender gets control only when they are not. Hard cash management appears more often when the lender is worried at the start, for example on a property with high vacancy, a single dominant tenant or a business plan that is not finished.

Worked example: what a sweep costs

Take the site's standard $1,400,000 loan. Assume a 6.5% rate and a 30-year amortization, which is an illustrative rate, not a quote. The payment is about $8,849 per month, or $106,187 per year. The loan agreement has a springing cash sweep: if the trailing DSCR drops below an illustrative 1.20x, the surplus is trapped. (Triggers differ by loan and lender. 1.20x is chosen to make the arithmetic clear.)

	At closing	After a tenant leaves
Net operating income	$190,000	$125,000
Annual debt service	$106,187	$106,187
DSCR	1.79x	1.18x
Debt yield	13.6%	8.9%
Surplus after debt service	$83,813 a year (about $6,984 a month)	$18,813 a year (about $1,568 a month)
Trigger of 1.20x	Passed. Surplus goes to the owner.	Missed. Surplus is trapped.

The results come from the DSCR calculator. A few things the table shows:

• The trigger needs a big drop. A 1.20x floor equals NOI of $127,424 ($106,187 × 1.20). From $190,000 that takes a decline of about 33% before the sweep starts. The sweep is a downside tool; it does not fire on a normal bad quarter.
• The money affected is small, and the timing is not. Only $18,813 of surplus is trapped per year here. But it is trapped during the exact period when the owner needs cash to re-lease the space.
• The cash is not lost. It sits in the account. Whether it comes back depends on the cure clause, and on whether the documents let you spend it on leasing costs before then.

If the cure requires the DSCR to be at or above 1.20x for two consecutive quarters, then in this example the NOI has to recover to at least $127,424 on the lender's calculation and stay there. A replacement tenant who signs a lease but has not started paying rent does not help the trailing number yet.

Why lenders use sweeps

Lenders think in terms of when they find out about trouble. Annual financial statements arrive months after the year ends. A sweep is a way to be paid for the risk while there is still cash at the property.

• It builds a cushion. Each month of trapped cash is a month of reserve that could fund debt service, taxes or leasing costs if income keeps falling.
• It discourages distributions. If the owner cannot take the cash out, there is more incentive to fix the property.
• It prices the loan. A lender willing to accept a higher leverage point, a smaller debt yield or a non-recourse structure will usually ask for tighter cash controls in return. See non-recourse loan.
• It is the first step before default. A sweep is a softer remedy than acceleration or foreclosure. It lets the lender intervene without calling the loan, which is why many borrowers prefer it to a hard financial covenant default. See loan covenant.

Rating agencies and bond investors also look for these provisions in securitized loans, because a loan with cash controls is more likely to build a reserve before it fails. That is one reason the structure is so common in CMBS.

Common sweep triggers

• Low DSCR. The most common trigger. It compares net operating income with debt service over a trailing period. See DSCR.
• Low debt yield. NOI divided by the loan balance. It ignores the interest rate and the amortization, so it is harder to game. See debt yield.
• Major tenant events. The anchor gives notice, stops paying, files for bankruptcy, or goes dark, or a lease expires without renewal. For a single-tenant building this can mean the sweep is nearly a full one.
• Loan events. An event of default, a default on mezzanine or other affiliated debt, or a bankruptcy of the borrower or its sponsor.
• Maturity approaching. Some loans start a sweep a set number of months before the maturity date if a refinance or extension is not in place, so cash is accumulating toward the balloon payment.
• Missed reserve deposits. Failure to fund required reserves, which lenders often view as a warning sign. See escrow and impounds.

Cure and release: where the real fight is

Most borrowers read the trigger and skim the cure. The cure is what decides whether a sweep is a temporary inconvenience or a permanent one.

• What cures it. Typically the measured ratio recovers above the trigger for a stated period, often a number of consecutive quarters, or the cause of the event (a new lease, a cured default) is resolved.
• Who calculates. Cure often depends on the lender's or servicer's own calculation of NOI, with its own vacancy factor and its own treatment of expenses. Your numbers do not decide.
• How long the lender may hold the cash. A May 2026 federal appeals court decision (Aberdeen Developers, LLC v. Wells Fargo Bank, N.A., Seventh Circuit) reversed the dismissal of a CMBS borrower's claim over language that left unclear how long a servicer could hold excess cash after a sweep. Courts read the documents, and vague wording invites a dispute. Ask for an explicit release date or event.
• What the cash may be used for. Some documents let the borrower draw on trapped cash for approved leasing costs or operating shortfalls. Others do not. This matters a great deal in the months when the space is empty and you need money for tenant improvements and commissions.

What to watch for and negotiate

1. Ask for the DSCR calculation in writing. A trigger may be computed on an assumed amortizing payment even if your loan is interest-only. On our $1,400,000 example, interest-only payments at 6.5% are $91,000 a year, so NOI of $125,000 is a 1.37x coverage, but 1.18x if the trigger uses the amortizing payment. The same property is clear of the test in one case and swept in the other.
2. Prefer a springing structure to a hard lockbox on a stabilized property. It keeps your day-to-day control of rents and expenses.
3. Set the cure to be short and mechanical. One or two quarters at or above the trigger is easier to plan around than a lender's discretion.
4. Get the cash back for property needs. Negotiate the right to use trapped cash for approved leasing costs, capital items and shortfalls, so a sweep does not block the work that would end it.
5. Separate the trigger from the default. A missed coverage test should start a sweep, not an event of default. Check that cash management triggers do not also appear as default triggers in the covenants.
6. Look for a release on repayment or defeasance. The trapped cash should return to you when the loan is paid off, and the documents should say so. See defeasance and prepayment penalty if the loan has lockout costs.
7. Plan your own liquidity. Model a sweep as a month-by-month loss of distributions. If your investors expect cash every quarter, a sweep is a communication problem as well as a finance one.

Comparing offers

When two lenders quote similar rates, the difference is often in how much cash control they take. Compare:

• The type of lockbox: hard, soft or springing.
• The trigger metric and level, and the test period (trailing three months, twelve months).
• The cure test and who calculates it.
• What the borrower can do with trapped cash.
• Whether the lender keeps the cash at payoff.

Product pages show the usual shape of each loan type. CMBS loans typically run Up to 75% leverage with 5–10 yr terms; bridge loans are shorter and often carry closer cash controls while the property is being repositioned; permanent financing from banks and agencies handles cash control differently again. The right choice depends on your plan for the property.
