Weighted Average Unexpired Lease Term (WAULT) and Weighted Average Lease Expiry (WALE) are key metrics in UK property development finance, measuring the average remaining lease length across all tenants in an investment property. These indicators are especially relevant when the exit strategy relies on generating rental income rather than unit sales. A higher WAULT or WALE signals stronger income security, which enhances lender confidence and supports robust property valuations. Developers, investors, and lenders use these measures to evaluate future rental income stability and the viability of financing decisions, making them essential for income-focused development projects.
This sits beneath Yield Metrics, introducing a more specific variant of the measure without changing its core interpretation. It is commonly considered alongside Equivalent Yield, as both are closely related measures used to assess similar aspects of performance or risk. In funding terms, WAULT/WALE (if income exit) is most commonly encountered in connection with Return Tied to Cashflow Availability within the property development capital stack.
