Pay attention to the following points: 1. We can only sign a draft agreement with the top account party and pay the transaction amount after signing a contract with the developer. 2. You must get the official invoice of the developer in your hand and go through the relevant formalities such as the notice of residence permit before you can conduct the full transaction. In addition, the house price marked on the contract should be different from the amount that the top account bought for you. Generally, the former is higher, so some of your related taxes and fees should be paid according to the house price marked in the contract. Nothing else. The advantage of the top account room is that it is cheap, but the disadvantage is that it must be paid in one lump sum. At this time, you must personally go to the developer to verify this matter and see who the house is for and whether this person has valid documents. And you have to have a legal contract with him to avoid being cheated.
