如果租房子但打好契約也付押定金但後悔能要求退租嗎?

看房東ㄉ意思
有ㄉ比較好會扣一點點
不好ㄉ會扣到底
一班會收一各月吧
當違約金

It depends on how does the owner of house think about. To the contrary, however, I would rather hardly prefer you to beg pardon sincerely to the owner. By doing so, perhaps the relative can be able to accept your request.

因為你們已有訂契約,應履行契約上的條約
1.看房東有沒有人情味囉!
2.趕快提前告知,最多賠上一個月租金,其他應無條件退還!(文具行買的房屋租賃契約書有規定)
3.找個博取同理心的正當理由吧 !
