Lenders will often structure bridge loans with an interest reserve which can be sinking or non-sinking. An interest reserve is the interest due on the loan over a certain period, which is held back from the loan proceeds by the lender. For example, a 12-month interest reserve on a $5,000,000 loan at 12% interest will be $600,000*. At closing, the lender would advance $4,400,000 (before other fees are deducted). Under a sinking interest reserve, the lender takes the interest due each month from the interest reserve as payment. Over time the interest reserve is depleted. Under a non-sinking interest reserve, the borrower makes their monthly interest payment out of pocket. If the borrower fails to pay, the interest reserve is tapped (the lender would consider this a default).
