CMBS uses hard lockbox (tenants pay directly to a lender-controlled account), soft lockbox (borrower deposits collected rents into the controlled account), and springing lockbox (no lockbox until a covenant breach triggers conversion to hard or soft). Springing is the most common starting point on stabilized deals.
When is hard lockbox required from origination?
Higher-leverage transitional or value-add deals, single-tenant deals, hotels, and any deal where the lender wants direct control of cash from day one. Hard lockbox eliminates timing and reconciliation risk for the lender at the cost of borrower operating flexibility.
What converts a springing lockbox?
Stated trigger events: DSCR drop below threshold (often 1.10 to 1.20x), debt-yield drop below threshold (often 6.5 to 7.5 percent), tenant non-renewal events on single-tenant deals, or any event of default. Once converted, lockbox usually remains in place until performance recovers and stays at threshold for two consecutive quarters.
