Duration mismatch in property development finance UK arises when the maturity or interest reset periods of a loan do not match the timing of expected project cash flows. This misalignment can expose developers to refinancing risk, interest rate volatility, or liquidity shortages during the development lifecycle. It is especially relevant for structured finance and senior or mezzanine debt where repayment schedules and project completion dates differ. Properly assessing and managing duration mismatch helps UK property developers reduce financial stress, optimise capital allocation, and safeguard project returns in dynamic market conditions.
This sits beneath Finance Risk (Refinance, Interest Rates), introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Refi Rate Shock Tolerance, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, Duration Mismatch is most commonly encountered in connection with Rolled-Up Interest within the property development capital stack.
