What should I do if the corner of the new house leaks?

If the ceiling leaks, there is something wrong with the waterproof layer upstairs. Don't look for leaks, make a waterproof layer from a new side.

If it is a wall, check whether there is a pipe in the wall, and if there is a pipe, see if it is damaged.

If there is no pipe in the wall, it may be a broken part of the outer wall. If it is a building built in recent years, it may be that the insulation layer of the external wall is damaged and it is difficult to solve. Find a property quickly
