What is WALT in Real Estate?

WALT (Weighted Average Lease Term) is a metric used in real estate to measure the average remaining lease duration of a property’s tenants, weighted by their respective lease areas or rental income. It helps assess lease stability, income security, and tenant rollover risk.

How is WALT Calculated?

WALT is typically calculated using either leased area (square footage) or rental income as weights:

Formula (Based on Leased Area):

Weighted Average Lease Term Calculation

where:

  • Lease Term = Remaining years on each tenant’s lease
  • Leased Area = Tenant’s occupied space in square feet

Formula (Based on Rental Income):

Weighted Average Lease Term Calculation Using Annual Rent

where:

  • Annual Rent = Rent paid by each tenant per year

Why WALT Matters

  • Higher WALT = Stable long-term income, lower turnover risk
  • Lower WALT = More leases expiring soon, higher renewal risk
  • Used in investment analysis, property valuation, and lender underwriting
