"net operating income"

The annual income generated by a property after deducting all operating expenses, excluding debt service, depreciation, and income taxes

"Vacancy in two anchor units reduced the centre's net operating income by £340,000, causing the bank to require additional security before refinancing."

"comparable sales analysis"

"reversionary yield"

The yield that will apply to a property once the current lease expires and the rent reverts to the estimated rental value, indicating future income potential

"The office block offered a running yield of 5.1% but a reversionary yield of 6.8%, as rents had been agreed well below current market levels five years earlier."

"gross development value"

The projected open market value of a completed development scheme, used in residual valuation to determine the maximum land price a developer can pay

The face value of the contracted rent agreed between landlord and tenant, before accounting for any rent-free periods, capital contributions, or other incentives given to the tenant

"The headline rent of £55 per square foot looked impressive, but after a two-year rent-free period the effective rent worked out at £47 per square foot."

"rent review clause"

A provision in a lease that specifies when and how the rent will be reassessed during the lease term, commonly linked to open market value, RPI, or CPI

"The developer's viability assessment argued that providing more than 15% affordable housing would make the scheme financially undeliverable given current build costs and values."

"phased development"

An approach to large-scale development in which the scheme is divided into sequential phases, allowing income from earlier phases to cross-subsidise or de-risk later stages

"The master plan adopted a phased development strategy over fifteen years, with the residential phases funding the creation of a public park and commercial hub in the final phase."

"practical completion"

The stage at which a building contractor has finished the works to a standard that allows the building to be used for its intended purpose, triggering the transfer of risk and the start of the defects liability period

"BREEAM rating"

A sustainability assessment method for buildings produced by the Building Research Establishment, grading performance across categories including energy, water, materials, and ecology

"The new headquarters achieved BREEAM Excellent, which the occupier required as part of its corporate sustainability commitments and helped attract talent with environmental priorities."

"EPC rating"

An Energy Performance Certificate rating that measures the energy efficiency of a building on a scale from A to G, with A being the most efficient, increasingly important for lending and lettability

"Proposed legislation requiring a minimum EPC rating of C for all commercial lettings by 2027 put pressure on landlords to invest heavily in building upgrades or face void risk."
