Interest Reserve
An interest reserve is a pre-funded account, drawn from loan proceeds, used to pay loan interest during a period when the property does not generate sufficient cash flow — most commonly during construction, lease-up, or repositioning.
Interest reserves are how lenders finance interest payments during pre-cash-flow periods. On a construction loan or value-add bridge, the property does not yet generate NOI sufficient to service debt. The lender funds an interest reserve at close — typically calculated as average outstanding balance multiplied by interest rate multiplied by the pre-cash-flow period — and the borrower draws from it monthly to make interest payments. The reserve reduces net usable loan proceeds dollar-for-dollar.
How Interest Reserves Are Sized
Construction loan: Average drawn balance (typically 50–60% of commitment for ground-up, 65–75% for value-add) multiplied by interest rate multiplied by construction period. Bridge loan: similar calculation based on expected average balance and projected pre-stabilization period. The reserve is funded from the loan itself, not separate sponsor equity.
Impact on Net Usable Loan
A $15M construction loan with a $1.2M interest reserve and $150K origination fee delivers only $13.65M of usable capital for actual project costs. Sponsors who do not model interest reserve correctly find themselves capital-short halfway through construction.
Reserve Replenishment
Most loan documents require the borrower to replenish the interest reserve if it is exhausted before completion or stabilization. This is a significant covenant risk — sponsors should stress-test the reserve calculation against extended timelines.

Frequently Asked Questions
What is an interest reserve in a construction loan?
A pre-funded account, drawn from loan proceeds, used to pay loan interest during the construction period when the property does not generate income. Sized as Average Drawn Balance × Interest Rate × Construction Period.
Does the borrower pay interest reserve back?
The interest reserve is part of the loan principal — it accrues interest like any other drawn amount and is repaid at loan payoff. The reserve does not represent additional equity contribution; it is borrowed money used to pay interest on borrowed money.
What happens if the interest reserve is exhausted?
Most loan documents require the borrower to replenish the reserve from sponsor equity or other sources. Failure to replenish is typically a default. Sponsors must stress-test reserve sizing against extended construction or lease-up timelines.
How much does an interest reserve reduce net loan proceeds?
On a typical 24-month construction loan at 9.5% with 55% average draw, the interest reserve consumes approximately 5–7% of the commitment. On a $15M loan, that's roughly $750K–$1.05M of "loan" that never reaches actual project costs.
