IOV Valuer key terms

The reasonably probable, legally permissible, physically possible, financially feasible and maximally productive use of a property that produces the greatest value. It underpins every approach to value and must be tested at the valuation date.

The estimated amount for which an asset should exchange on the valuation date between a willing buyer and a willing seller in an arm's length transaction, after proper marketing, where each party acts knowledgeably, prudently and without compulsion.

The price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, as defined under IFRS 13 for financial reporting purposes.

The value of an asset to a particular owner or prospective owner for individual investment or operational objectives, reflecting that party's own assumptions, required return and tax position rather than general market evidence.

A transaction between parties who are unrelated, act independently and are each seeking their own best advantage, with no relationship or pressure that could distort the agreed price.

A hypothetical buyer or seller in the principal market for an asset who is knowledgeable, willing and able to transact, and whose assumptions and risk appetite frame the valuation inputs used.

Transaction or asking-price data from properties similar to the subject that is verified, adjusted for differences and used to indicate value. Reliability depends on proximity in time, location and physical characteristics.

A structured table that quantifies and applies percentage or lump-sum adjustments to comparable prices for differences such as location, size, condition, tenure and date of sale, producing an indicated value for the subject.

A market-derived adjustment applied to comparable evidence to reflect changes in price levels between the comparable's transaction date and the valuation date, often derived from repeat sales or price index movements.

The ratio of a property's net operating income to its capital value, expressing the market's required income return and growth expectation. It converts one year's income into an indication of capital value.

Gross rental and other income less operating expenses, vacancy and collection losses, but before finance costs, capital expenditure, tax and depreciation. It is the income stream capitalised or discounted in income-based valuations.

A valuation method that projects periodic net cash flows over a holding period, discounts each to present value at a market-derived rate and adds the present value of the projected sale proceeds.

The estimated value of a property at the end of the explicit DCF holding period, often derived by capitalising the following year's net income or by growth-based perpetuity formulae.

The rate applied to convert future cash flows into present value, reflecting the time value of money plus the risk and return characteristics of the asset or the investor's target return.

The estimated amount for which a property would be let on the valuation date between a willing lessor and willing lessee on appropriate lease terms in an arm's length transaction after proper marketing.

A contractual mechanism allowing the rent under an existing lease to be reset to market level or by an agreed formula at specified dates, affecting the income profile and risk of the investment.

A right to occupy and use property for a defined term under a lease, with value dependent on the relationship between contract rent and market rent, remaining term and lease covenants.

Absolute ownership of land and buildings for an indefinite duration, subject to statutory controls and any encumbrances, representing the fullest bundle of property rights recognised in the jurisdiction.

A right or interest burdening a property, such as a mortgage, easement, covenant or restrictive condition, that may limit use or transfer and must be identified and analysed in the valuation.

The current cost to construct a modern equivalent asset of equal utility to the subject, using current materials, standards and technology, before deducting depreciation. It is the starting point of the cost approach.

The current cost of constructing an exact replica of the subject using the same materials, design and construction methods, before deducting depreciation. It is used where heritage or unique features matter.

The total loss in value from the cost new of an improvement at the valuation date, comprising physical deterioration, functional obsolescence and external obsolescence, however caused.

A loss in value not caused by physical wear, arising either from outdated design or specification (functional) or from factors outside the property such as market, locational or regulatory change (external).

The period over which an improvement is expected to contribute to the value of the property, ending when its contribution falls below the value of the land for an alternative use.

The land value derived by deducting development costs, fees, finance and a developer's profit from the completed project's value, commonly used where direct land evidence is scarce.

The reward required by a developer for risk, effort and capital employed in a project, usually expressed as a percentage of gross development value or of total cost in residual appraisals.

A ratio of sale price to gross income, used as a quick check of value where expenses and lease structures are broadly comparable across the evidence set.

A deduction from gross potential income for expected voids, rent-free periods and collection losses, reflecting the property's market, lease profile and tenant quality.

A property with a design, construction or location suited to a single use, rarely sold except as part of a going concern, so that market evidence is scarce and cost-based methods often carry more weight.

A method combining replacement cost new with deductions for physical deterioration and obsolescence, used for special-purpose assets where market evidence is unavailable; it is a cost-based proxy, not a market price.

The value of a business or operating asset in its current use, including the assembled workforce, contracts, licences and operating synergies that would not transfer with the physical asset alone.

The principle that valuation analysis and reporting should focus effort and disclosure on matters capable of influencing decisions, so that immaterial detail does not obscure significant findings.

The agreed extent of research, inspection, analysis and reporting required for a valuation assignment, determined by the purpose, intended use and materiality, and documented before work begins.

The written agreement recording the client, intended use, asset, basis and date of valuation, assumptions, limitations, fee, and the valuer's responsibilities before the assignment starts.

The written output stating the value conclusion, basis of value, valuation date, methods, key inputs, assumptions, limitations and the valuer's compliance with applicable professional standards.

The fundamental premise on which the reported value is stated, such as market value or investment value, identifying the assumed transaction conditions, parties and any special assumptions applied.

The ethical requirement that a valuer's judgement is unaffected by personal interest, fee dependence, client pressure or other conflicts, with any threat disclosed or the instruction declined.

A situation where a valuer's other interests, relationships or prior involvement could bias the opinion, requiring disclosure, safeguards or withdrawal so that objectivity is preserved.

A temporary use of land or buildings that is physically possible and financially worthwhile pending a higher use, and which must not prejudice the eventual highest and best use.

The observed price effect whereby energy-efficient, certified buildings attract higher values or rents and weaker assets face discounts, reflecting occupier demand, operating costs and regulatory risk.

The risk that a property loses value or becomes unlettable before the end of its expected life because of climate transition, energy regulation or changing occupier expectations.

The potential effect on property value from acute hazards such as flooding, wildfire or storm, and chronic shifts such as sea-level rise, assessed through exposure, vulnerability and insurability.

Reporting of environmental, social and governance performance of a property or portfolio, including energy ratings, carbon metrics and certifications, which increasingly informs valuation inputs and lender decisions.

A statistically calibrated system that estimates value from property attributes and transaction data without individual inspection, requiring validation, transparency and limits on use for complex or high-risk decisions.
