A cash sweep is a loan mechanism that redirects a property's excess cash flow, the money left after operating expenses and debt service, to the lender once a performance trigger is breached. It removes the borrower's discretion over surplus cash until the trigger cures.
How a Cash Sweep Works
A cash sweep is triggered by a measurable performance test written into the loan documents, most often a debt service coverage ratio or debt yield falling below a set floor. Once breached, property rents route through a lockbox to a lender-controlled account, and surplus cash is trapped rather than distributed.
The most common trigger is the debt service coverage ratio, or DSCR, calculated as net operating income divided by debt service over a trailing window. Trigger floors are typically negotiated in the range of 1.10x to 1.25x. Debt yield, net operating income divided by the loan amount, is a second common test, with sweep floors typically set in the range of 7 to 8 percent. Some sweeps also spring on a lease rollover, a major tenant bankruptcy, or a failure to refinance ahead of a balloon maturity.
Mechanically, the sweep sits on top of a lockbox and a cash management agreement. Rents flow into the lockbox, then to a lender-controlled cash management account. When no trigger is active, funds pass back to the borrower. When a trigger is active, the surplus is held, applied to reserves, or applied to principal, depending on the loan terms.
The structure is either springing or hard. A hard, or in-place, structure sweeps and controls cash from day one. A springing structure leaves cash with the borrower until a trigger fires, at which point control springs to the lender. According to the Scotsman Guide, roughly 70 percent of CMBS loans use springing cash management, where the servicer takes control of cash flow if DSCR falls below the contractual level or a major tenant departs.
Why a Cash Sweep Matters
A cash sweep matters because it strips the borrower of discretionary cash flow at the exact point in a business plan when that cash is most needed. Trapped funds cannot fund tenant improvements, leasing commissions, distributions, or capital projects, so a sweep can stall a turnaround it was meant to protect against.
For an operator, a sweep converts a soft performance dip into a hard liquidity event. A property still covering debt service can lose access to every dollar above it, freezing distributions to equity and starving the leasing capital needed to re-tenant and cure the trigger. Getting into a sweep is fast; getting out is slow, because cure tests run on a trailing basis and often require several consecutive quarters above the floor.
The educational site Adventures in CRE frames the asymmetry plainly: a cash sweep protects the lender's position by paying down the balance when the borrower's ability to perform is in doubt, while creating real operational strain for the owner. That is why cure mechanics, trigger levels, and the definition of the tested metric are among the most negotiated terms in any leveraged loan.
Example
The example below is a stabilized office loan where a debt service coverage ratio floor of 1.40x governs the cash sweep. When net operating income falls and the ratio drops to 1.35x, the sweep springs, and every dollar of surplus cash flow is routed to the lender. The figures mirror a worked scenario published by Adventures in CRE.
Line item | Amount |
|---|---|
Net operating income (annual) | $2,500,000 |
Debt service (annual) | $1,850,000 |
DSCR (NOI divided by debt service) | 1.35x |
Sweep trigger (DSCR floor) | 1.40x |
Surplus cash flow swept | $650,000 |
DSCR of 2,500,000 divided by 1,850,000 equals 1.35x, below the 1.40x floor, so the trigger fires. The $650,000 of surplus that would have gone to the owner is instead swept to the lender until DSCR is restored above 1.40x for the required cure period.
Variations and Edge Cases
A cash sweep is not one structure but a family of them, varying by trigger metric, cure terms, and how funds are applied. Some sweeps pay down principal, some fund reserves, and some hold cash as additional collateral. Trigger tests range from DSCR and debt yield to lease rollover and tenant bankruptcy.
Variation | Behavior |
|---|---|
Full sweep | All surplus above debt service is trapped |
Partial sweep | A stated percentage of surplus is trapped, the remainder released |
Reserve sweep | Trapped cash funds a reserve rather than paying principal |
Springing sweep | Control activates only on a trigger event |
Hard sweep | Control applies from origination regardless of performance |
A recurring trap is the tested metric being defined against underwritten or market assumptions rather than actual performance, which can spring a sweep on a property that is paying its debt in full. Borrower's counsel guidance, such as the Holland & Knight CMBS primer, stresses reading the cash management and trigger definitions closely before closing.
Cash Sweep vs Lockbox
A cash sweep is often confused with a lockbox, but they are different layers of the same control system. A lockbox is the bank account that receives tenant rent. A cash sweep is the rule that decides whether trapped funds stay with the lender or return to the borrower.
Feature | Cash Sweep | Lockbox |
|---|---|---|
What it is | A rule that traps surplus cash | A bank account that collects rent |
Function | Decides where cash goes on a trigger | Receives and holds tenant payments |
Active when | A performance trigger is breached | Always, or springing on a trigger |
Governed by | Cash management agreement | Deposit account control agreement |
A lockbox can exist without an active sweep: rent collects in the account and passes back to the borrower until a trigger fires. The sweep is the enforcement layer that redirects that cash to the lender.
Frequently Asked Questions
What triggers a cash sweep?
A cash sweep is triggered when a loan's performance test is breached, most commonly a debt service coverage ratio or debt yield falling below a contractual floor. Common DSCR triggers fall in the range of 1.10x to 1.25x, though the exact level is negotiated per loan.
Is a cash sweep the same as a default?
No. A cash sweep is a cash control remedy, not an event of default. The loan stays current and the borrower keeps title. The lender holds surplus cash flow until the trigger cures, which protects the lender without accelerating the loan.
How does a borrower get out of a cash sweep?
A borrower exits a cash sweep by curing the trigger for a defined period, often two to four consecutive quarters of the metric holding above the floor. Getting into a sweep is fast; getting out is slow, because cure windows are measured on a trailing basis.
