A portfolio metric expressing the average remaining lease duration across a set of leases, weighted by each lease's contribution to total revenue or square footage.
WALT (Weighted Average Lease Term) is a standard metric in commercial real estate portfolio analysis and REIT reporting. A higher WALT signals more predictable future cash flows and lower near-term rollover risk. Calculated by multiplying each lease's remaining term (in years) by its annual rent (or square footage), summing those products, and dividing by total portfolio rent (or square footage). For example, a portfolio with two leases — one generating $100k with 3 years remaining and another generating $200k with 6 years remaining — has a WALT of 5 years. Lextract surfaces WALT calculations from abstracted portfolio data automatically.
