The German income approach (German: Ertragswertverfahren, abbr. EWV) is the standard approach used in Germany for the valuing of property that produces a stream of future cash flows. For general information on German real estate appraisal please look here. == Basic principles and regulations == The EWV is one of three valuation methods codified by German legislation. The ''Vergleichswertverfahren'' (sales comparable approach) is mainly used to determine the value of owner-occupied buildings (single-family houses, condominiums) and land. The ''Sachwertverfahren'' (cost approach) is only used for special use properties that do not produce a measurable future cash flow. Subsequently, the EWV is used for the vast majority of appraisals. Even though the EWV is mostly consistent with international practice, there are some important differences: *Land and improvements are treated separately. German Generally Accepted Valuation Principles (GAVP) assumes that the land can be used indefinitely, but that buildings have a limited lifespan; This coincides with the balancing of the assets. The value of the land is determined by the sales comparison approach in both the income and cost approaches, using the data accumulated by the ''Gutachterausschuss'' (local valuation committees, lit. "expert committees") which is then added to the building value. *In order to account for the usage of the land by the buildings occupying it, the net operating income is reduced by the ''Liegenschaftszins'' (interest paid to the land-owner by the owner of the building, i.e. ground rent). The ''Liegenschaftszins'' is the product of the land value and the ''Liegenschaftszinssatz'' (interest rate for land-use). The ''Liegenschaftszinssatz'' is the equivalent of the yield − with some important differences − and is determined by the ''Gutachterausschuss''. *Unlike the All Risks Yield (ARY) in UK practice, the ''Liegenschaftszinssatz'' (LZ) does not include an allowance for default (not to be confused with structural vacancy), and therefore this should be subtracted from gross operating income. As a result, the ''Liegenschaftszinssatz'' will usually be lower than the All Risks Yield. *Based on the assumption that the economic life of the improvements is limited, the yield and remaining economic life determine the building value through the net operating income. *It should be additionally noted that contracts in Germany generally prescribe that the landlord bears a higher portion of maintenance and operating costs than their counterparts in the US and UK. Real estate appraisal in Germany is regulated by the federal Baugesetzbuch (abbr. BauGB, the German statutory code of building and construction).〔(Definition of market value in German )〕 This federal law is supported by the Wertermittlungsverordnung (abbr. WertV, "regulation on the determination of value").〔(German text of the WertV )〕 The WertV defines the codified valuation approaches and the general valuation technique. WertV's general regulations are further supported by the Wertermittlungsrichtlinie (abbr. WertR, "directive on the determination of value").〔(German text of the WertR )〕 The WertR provides templates for calculations, tables (e. g. economic depreciation) and guidelines for the consideration of different influences. WertV and WertR are not binding for appraisals for non-official use, nonetheless they should be regarded as best practice or German Professional Appraisal Practice (PAP). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「German income approach」の詳細全文を読む スポンサード リンク
