I paid a deposit to the property with the decoration company, but I need to tear down the walls and

This is related to the security aspect, and the property certainly does not want to take on this responsibility. But as long as it's not a load-bearing wall, it's fine, you change it first, and then say, it's impossible for the property to demolish you. As long as it's not a load-bearing wall, it's fine.

Even if your deposit is deducted, it's okay, if you think about it, you can live comfortably in the future, even if you buy it, you can add tens of thousands of yuan, and you won't lose it.

Because it involves a waterproofing issue.

If the waterproofing is not done well, and the water seeps into your own home, it is your own business, and if it seeps into other homes, causing losses and disputes, you will have to compensate for the loss ......If it's a water leak, it's even worse......

If you want to expand, you can also do it, you can write a letter of responsibility for the property, clarify the responsibility and then suggest that you find a regular company, and ask how long the waterproof warranty period is before doing ......

As long as the use of the house is not changed, as long as the load-bearing structure part is not involved, and the part of the building façade is not changed, other changes are their own business, and others have no right to interfere. Whether the waterproof is done well or not is my responsibility. The property has no right to interfere.

Who's called the community? Property is definitely to be managed. Generally speaking, as long as it is not a load-bearing wall, it is possible to pay some money. Otherwise, it won't work.
