What should I pay attention to when buying a second-hand house?

There are two main points: first, the quality of the house. For quality problems, you can find a house inspection company to help you inspect the house. The price is not expensive, 100 square meter, that is, 250 yuan. Of course, if you have experience, you can also inspect the house yourself. I won't talk about the big aspects of house inspection. The most important points must be carefully read: 1. Area. This question is ambiguous. One square is thousands or more than ten thousand. 2. the wall. Knock with a hammer. Listen for empty drums. If there is an empty drum, the developer must fix it. Otherwise, the whole house will not be soundproof. 3. waterproof. The easiest way to see if the bathroom is waterproof is to look at the top of your bathroom to see if there are any water marks. The second is the certificate. 1. Residential quality certificate. Instructions for use, others are not very important. There is no need to test everything.
