Generally speaking, the risk of house damage or loss is transferred to the buyer from the date of house delivery. Of course, if there is an agreement on this situation in the contract or both parties can solve it through consultation, the agreement of both parties shall prevail.
If the seller has truthfully informed the house decoration that there are defects or you know the defects, the seller will not be responsible; If there is no problem when it is sold, just because the decoration is old and unlucky, and there is a problem after just living for five days, you have to repair it yourself.
