ERV (Estimated Rental Value)
The open market rent the property would achieve if leased today.
Asset Management
Operational terms for running a portfolio.
WAULT
Weighted Average Unexpired Lease Term. The average time remaining on all leases, weighted by rent.
Sum(Remaining Term_i * Rent_i) / Sum(Rent_i)Void Period

GDV - ConstructionCosts - Fees - TargetProfit = LandValueOverage
A clause where the land seller gets extra money if the developer achieves a higher value than expected.
Practical Completion (PC)
The point when the building is 'finished' and ready for occupation, triggering lease starts and warranty periods.
ESG & Trends
Environmental and modern market factors.
Stranded Asset
A property that will become obsolete due to new environmental regulations (e.g. failing minimum EPC standards).

Global certification systems for rating the sustainability of buildings.
