Months of vacancy assumed between tenant departure and replacement.
Standard underwriting assumption: 6–9 months downtime in gateway-city Class A. Lengthens to 12–18 months in lease-up buildings or markets with high vacancy.
Downtime assumption is part of the investment vocabulary that institutional Class A occupiers, landlords, and advisers use across Global markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks regional variation alongside the global standard so cross-border occupiers can translate quickly.
