土地の売却期間は47日と分析したが、中古マンションの売却期間についても、土地と同様に分析してみた。
中古マンション分析データは、土地の分析と同じ不動産情報会社の中古マンション取引事例データ(専有面積40u以上)を利用して、分析してみた。
都内世田谷区の平成25年(2013年)1月1日〜12月31日までの1年間に取引された中古マンションの取引事例184例(専有面積40u以上)の売出し価格、契約価格、値引きした場合の値引率、そして売却する為の情報公開日から売却の契約日までの日数を調べて見た。
中古マンション取引184件(専有面積40u以上)のうち、値引き等により当初売出し価格と契約価格とが異なった物件は、24件であった。
価格変動した物件の割合は、
24÷184=0.130
0.6%〜13.1%
平均日数 34.8日
標準偏差 23.6(日 変動係数0.678)
34.8+23.6=58.47≒58
