Analytical Proof & Invariants

Machine Precision
Governing Mathematical Formula:
Interest Reserve = Monthly Interest Payment × Stabilization Months

Step-by-Step Mathematical Derivation

1
All-In Floating Rate Formula

All-In Rate = SOFR Index + (Spread Basis Points / 100). For example: 5.25% + (375 / 100)% = 9.00%.

2
Monthly Interest Payment

Monthly Interest = (Facility Amount × All-In Rate) / 12 = ($5,500,000 × 9.0%) / 12 = $41,250/mo.

3
Lender Reserve Holdback Escrow

Interest Reserve = Monthly Payment × Stabilization Term = $41,250 × 18 months = $742,500. The lender holds this cash in escrow to make interest payments while the property is renovated and re-tenanted.

Frequently Asked Questions

What happens if a property stabilizes before the interest reserve is exhausted? +
Unused interest reserve funds are not kept by the lender. When the bridge loan is paid off through a permanent refinance or sale, any remaining balance in the interest reserve escrow reduces the final loan payoff balance dollar-for-dollar.
What is an interest rate cap in commercial bridge lending? +
Because bridge loans have floating interest rates, lenders mandate that borrowers purchase an Interest Rate Cap (derivative hedge) that sets a maximum ceiling on SOFR to protect against default during rate spikes.
