The leakage problem of the purchased commercial house has been delayed for five years and has not been maintained. What if you can't decorate? I'm so worried!

From a technical point of view, some leaks are caused by the structure of the building. I want to know what floor your building is on. What floor is your home on? What are the loopholes?

I know that there is a wall that leaks when it rains, but the problem is that the outer floor is not waterproof well during construction and leaks from cracks. Fortunately, there are many such problems in that building, and the internal repair is ineffective. The developer has made exterior waterproofing as a whole.

Some things still need to be considered from many aspects. It is recommended to find a professional to check it first. If you can find the leak, fix it first. If you can't fix it, you must know what the problem is. You can claim compensation at that time.

It seems that you are not going to give up this house. We can collect some evidence first. For example, you say you can't move in after paying the money. If you don't move in, you will have to charge a property fee. There is no service if you charge property fees. Consult a lawyer and see how to solve it. The key is to see what you want to achieve.

Really can't. Giving up is also a way.
