Support the 4 th floor view, the developer is too unscrupulous. Why not communicate with the owner in advance before the pre-sale certificate comes down? There are two aspects: 1. If it is forced to change by government departments, it is a necessary legal procedure for developers to sell houses, which has nothing to do with the owners; If the developer needs to change it himself, common sense will definitely be good for him. As for why he didn't communicate with the owner in advance, the reasons are as follows: 1) It is illegal for the owner to sign an appointment agreement without obtaining the pre-sale permit, and the lawsuit requires the developer double indemnity to make a deposit; 2) Developers don't have enough funds to develop real estate, so they need to borrow money from owners to maintain the capital flow. For their own economic interests, they don't discuss with the owners in advance. The above two points are in the interests of developers and harm the interests of owners. Such developers regard the law enacted by the Supreme Court as a tool to exploit the owners, and now they need to pay an extra 280 yuan/square meter, and sign a compulsory contract to entrust renovation contract, which is simply a matter of heaven!
