PARA PENILAI, HATI-HATI! EVALUASI ATAS AKURASI TEKNIK ESTIMASI PENYUSUTAN NILAI BANGUNAN DALAM PENDEKATAN BIAYA UNTUK PENILAIAN PROPERTI
MENGAPA PENGGUNAAN PENDEKATAN BIAYA DALAM PENILAIAN PROPEPERTI DAPAT MENGHASILKAN NILAI YANG KURANG AKURAT DALAM ERA PANDEMI?
The property valuation method widely used in Indonesia is the cost approach. The basic assumption of this method is that property value can be estimated based the cost in obtaining that property. This method is therefore most appropriate for newly developed property. For properties in a different condition, valuers need to take into account the decrease in value as a result of obsolescence. From the three commonly-recognised obsolescence – physics, economics, and function – most valuers tend to estimate only physical obsolescence in their value estimate although it has the least effect on property value. This paper proposes a technique to estimate the total decrease in value as a result of all three types of obsolescence. The simulation reported in this paper shows that the proposed technique is able to produce an estimate of obsolescence that is statistically more accurate.
