FoundationsA short valuation glossary.
The quick explanation leads directly to the in-depth main article with sources and examples.
- Market value
The price that can usually be achieved in a sale in an arm’s-length transaction. This is distinct from the particular personal preferences of individual interested parties.
Context and sources- Valuation date
The date to which the valuation relates. Market conditions, condition and legal circumstances must be considered as of that date.
Context and sources- Sales comparison value
A valuation derived from suitable comparable transactions. Differences in timing, location, condition and other features affecting value must be taken into account transparently.
Context and sources- Cost-based value
An assessment of land value, building value and, where applicable, other components. Age, condition and market circumstances influence the valuation; construction costs alone are not a guaranteed sale price.
Context and sources- Income-based value
A valuation derived from sustainably achievable income. Operating expenses, useful life and justified capitalisation are among the essential foundations.
Context and sources- Net income
The income remaining in the valuation model after the operating expenses to be considered. The costs included must suit the specific calculation and be disclosed.
Context and sources- Remaining useful life
The period during which a building is reasonably assumed to remain economically usable. The year of construction alone is insufficient; condition, modernisation and usability must also be assessed.
Context and sources- Residual value
An amount remaining from assumed development proceeds after deducting the estimated costs and other model items. Small changes in the assumptions can substantially alter the result.
