The property is unfavorable to the owner personally.

You'd better find an inspector to check this problem. After all, your house is there, and it is normal to doubt your home. In terms of responsibility, you don't need to be responsible before technical appraisal, and they have no right to ask you for maintenance compensation. The answer to your question is as follows:

1. Only the builder knows that there are scattered things in the house, so there may be everything. If it's a bean curd project, they have to compensate you.

2. Just let the property issue a technical appraisal result certificate. Without the appraisal result, they can't help you.

3, in the absence of evidence to prove that your home is leaking, you have an advantage, just don't have physical conflicts.

The above is personal experience, purely for reference.
