WAULT (weighted average unexpired lease term) is an indicator that represents the average time remaining until the expiration of lease agreements in a property portfolio. This metric is calculated as a weighted average of the lease durations, based on the rent and the area of individual properties. WAULT provides insights into the stability of rental income and the long-term security of an investment in commercial real estate. A higher WAULT indicates a longer period for which tenants are bound by lease agreements, which can contribute to greater stability and predictability of income.
