1, the original owner died in a car accident, which shows that there is something wrong with the geomantic omen of this house, but it is not necessarily whether this problem has affected your home. Even if it does not affect your family, it is recommended to redecorate after buying.

Generally speaking, the probability that this house can be bought should be below 30%.
