Case: Bridge exit requires more amortization than current debt

Hypothetical bridge maturity. A property produces $550,000 of accepted annual cash flow and carries a $5 million interest-only bridge at 7%. Annual interest is $350,000, so current coverage is 1.571×. The owner expects a permanent loan at the same 7% note rate and assumes its repayment capacity will be similar.

The proposed permanent lender instead requires monthly amortization over twenty years and 1.25× minimum DSCR. A separate alternative uses thirty-year monthly amortization at the same rate and coverage requirement. Both are fictional financing cases. The property is assumed to qualify for consideration, but neither is an executable quote.

Isolate amortization from the note rate

For a level monthly amortizing payment, monthly rate is annual nominal rate divided by 12. Payment equals principal × monthly rate ÷ [1 − (1 + monthly rate) raised to the negative number of payments]. Multiplying the payment by 12 and dividing by principal gives the annual debt-service constant.

At 7%, the twenty-year constant is approximately 9.30359%, while the thirty-year constant is approximately 7.98363%. Both exceed the 7% interest-only cash rate because payments include principal reduction. The extra cash is not all a financing expense; some repays debt. Nevertheless, it must be available when each payment is due.

The OCC loan-structure discussion explains why current interest-only coverage does not eliminate balloon risk. It does not mandate either amortization period in this case. The actual lender must identify the repayment schedule used in its sizing.

Calculate capacity before comparing the payoff

Assume an independently stipulated $8 million value and 65% maximum LTV, creating a $5.2 million collateral ceiling. Gross permanent debt is the lesser of that amount and cash flow divided by 1.25 and the relevant constant.

A lender quoting less than $5 million has not necessarily challenged the property’s value or applied a higher interest rate. In the twenty-year case, the amortizing payment consumes the coverage capacity. A useful comparison should identify that mechanism directly.

The thirty-year alternative has more gross capacity but also leaves a different principal path over time. Its stated availability, maturity and other terms must be confirmed. A borrower cannot select a schedule from a calculator and treat it as an approved product.

Add the closing uses that current coverage cannot pay

Assume the bridge payoff includes $5 million principal plus $75,000 of documented hypothetical accrued charges and exit costs. New-loan costs are 2% of the gross permanent loan. No reserve refunds or additional deposits are included.

The twenty-year loan nets approximately $4,634,771 after its new-loan costs. Against $5,075,000 payoff uses, the owner must contribute $440,229. The thirty-year alternative nets $5,096,000 and leaves only $21,000 before any excluded use.

The latter result is a narrow surplus, not a large cash-out refinance. An additional $30,000 reserve would turn it into a $9,000 contribution requirement. Keeping the payoff and fee bases explicit prevents a comparison based solely on whether gross proceeds exceed old principal.

Solve the income needed for the twenty-year route

To fund $5,075,000 after 2% new-loan costs, the required gross loan is approximately $5,178,571. That is below the stipulated $5.2 million collateral ceiling. At 1.25× coverage and the twenty-year constant, it needs approximately $602,241 of accepted annual cash flow.

The gap from the current $550,000 is about $52,241 annually. The owner should identify what recurring evidence could support that change and when. Adding projected rent without the related concessions, vacancy, operating costs and capital assumptions would not establish the threshold.

Alternatively, the owner can contribute the modeled $440,229, if verified and available while preserving other obligations. The contribution pays down the amount that must be refinanced; it does not increase NOI or justify labeling the property as having higher coverage under the original debt amount.

Compare timing as well as the apparent cure

If the owner expects the extra cash flow only after a leasing milestone, the bridge may mature before the necessary evidence is available. An extension then requires its own effective terms, cost, conditions and funding. The OCC refinance-risk discussion supports testing repayment at the actual maturity, not assuming current payment performance guarantees an extension.

A lower coupon on the twenty-year loan could also improve capacity, but only an actual supported proposal changes the decision. The model should not solve the shortfall by entering a desired rate. Likewise, interest-only permanent payments may still be sized on an amortizing convention under the lender’s terms.

The decision record should therefore state one of three funded paths: accepted twenty-year debt plus the required contribution, a confirmed alternative schedule that covers all uses, or a documented timing change that allows supported income to reach the threshold. Comfortable bridge interest coverage is evidence about today’s payment, while permanent refinancing is a separate test of tomorrow’s full obligations.
