TheComparativeApproach Ing. David Slavata, Ph.D. PropertyValuation
Principle • Itisnecessary to haveat least tworealestateswithnearly no differences (flat A, flat B) • Flat A (valuated) theunknownprice, theotherespeciallytechnical and legalparametres are known • Flat B (comaprative) knownprice, knowntechnical and legalparameters
Methods • Direct comparative • Professional balance sheet • Usingthe direct increases and reductions • Usingthecoefficients • Direct with no representative • Undirectwithrepresentativeestate
Example Valuatemultiflat house in thevillageof Svatoňovice by comparativeapproach. Builtfrombricks, insulated. In the house there are 4 similarflats 2+1. Appartement area 57m2. No balcony. Use thecomapartivemethodes. Theyearofconstruction: 1963.
Professional balance sheetmethode CV1 = 1/n x SUM SPi
Advantages and disadvantages • Simplemethode • Assumptionofhigh homogenity offlats • Timeliness • Sample ofusage: Flatsfor instance
Methodeofcomparison, 1.Direct. Usingofincreases and reductionsduethediferencesbetweenvaluated and comparableflats. 2. Usingthecoefficients express ofdifferences.
Direct methodeusingincreases and reductions CV2a = [(SPA +/- sum IRAi) x W1 + (SPB +/-sumIRBi) x W2 +….+(SPX +/- sum IRXi) x Wz] / W1 + W2+ … + Wz
Calculation CV = (+390 x 0,85 + 50 +0 + 39 +650 x 0,85 – 100 – 50 – 50 +580 x 0,85 - 100 + 0 – 50) / 3 CV = Kč/flat
Usingthecoefficients express ofdifferences CV2b = sum ISPCi / n ISPCi = SPi / Idi Idi = k1 x k2 x k3 x…..x kn
Procedure • To getthe database withthecomparativefltas as homogenuos as possible. • Thebidpricesofflatsshouldbecorrected by thereductioncoefficient. • Selectionofsignsofdifferencesshouldbe set thecoefficientsofdifferences (k) • By multiplicatingofcoefficientswegettheIndexesofdifferencesforeachcomparativeflat. • Thesellingpriceshouldbedevided by the Index ofdifferenceforeachflat. • By theaverageofadaptedsellingpriceswegetthecomparativevalueofthetheflat.
