Loan terms that let a lender control a property's rent money when performance slips: covenants, lockbox accounts and cash sweeps.

Covenants are promises in the loan, such as keeping DSCR above 1.20x or the guarantor holding minimum cash. A lockbox routes rent into a lender-controlled account: 'hard' if tenants pay it directly, 'soft' if the owner deposits it, 'springing' if it switches on only after a trigger. Triggers include DSCR or debt yield below a floor, or a major tenant leaving. A cash sweep then traps cash left after taxes, debt service and approved expenses, usually until the ratio recovers for two quarters.
Why it matters
A sweep can cut off an owner's distributions long before any default, so trigger levels and cure terms matter as much as the interest rate.
Facts, rules and data
CMBS loan agreements and offering documents, rating-agency criteria, bank loan covenants, and servicer reports that flag loans in 'cash trap' or cash management.
Debates and risks
How often banks quietly waive covenant breaches rather than enforce them is hard to see from public data.

▸Debt service coverage ratio (DSCR) below a trigger sets off Loan covenants, cash sweeps and lockboxesFact, law or data
The connection
The loan sets a DSCR floor, often 1.10–1.25x, tested quarterly. If net operating income falls, say after a big tenant leaves, the ratio drops below it, a springing lockbox switches on and surplus cash is swept into a reserve until DSCR stays above the trigger, usually for two quarters.
When and why
Written into CMBS, life-company and many bank loan agreements, and tested on the borrower's quarterly or annual operating statements.
How we know
Loan agreements spell out the triggers; CMBS servicer reports flag loans that have entered cash management or a cash trap.
Debates and risks
Whether sweeps help, by building a cushion, or hurt, by starving buildings of cash for tenant improvements, depends on how lenders release reserves.
▸Loan covenants, cash sweeps and lockboxes are standard in CMBS: conduit loans pooled into commercial mortgage bondsFact, law or data
The connection
Because a CMBS trust cannot easily renegotiate, lenders build controls in from day one: tax and insurance escrows, reserves for leasing costs, and a lockbox, often springing, that sweeps cash on a DSCR or tenant trigger. Rating agencies expect these terms before rating the bonds.
When and why
In nearly all US conduit and single-borrower CMBS loans since the 1990s, written into each loan agreement and cash management agreement.
How we know
CMBS offering documents, whose loan-level annexes list each loan's lockbox and cash management type, and published rating-agency criteria.
Debates and risks
Whether strict cash controls lower CMBS losses enough to justify their cost to owners has not been well measured.
▸ACH: Nacha's batch network for payroll, rent and bills often moves tenant rent through Loan covenants, cash sweeps and lockboxesFact, law or data
The connection
Tenants paying rent by ACH send it straight into the property's deposit account, often a lender-controlled lockbox under a CMBS loan. Swept daily to a cash-management account, the cash is paid out monthly in a set order: tax and insurance reserves, debt service, other reserves, approved expenses, then any excess to the owner or a trapped reserve.
When and why
Commercial properties with lender lockboxes; tenants receive direction letters telling them to pay into the lockbox account.
How we know
Cash management agreements and tenant direction letters in CMBS loan documents.
Debates and risks
How often owners divert rent outside lockboxes, a carve-out trigger, is unknown until a default exposes it.
