When signing an online contract, the salesperson should explain all the key points to you face to face, but when you choose to buy a house, please make sure that the name on the real estate license is that the salesperson should collect relevant documents from you and submit them to the bank for credit investigation (whether there are loan records or bad records), and then go to the Housing Authority to issue a real estate license. These tasks must be completed before signing the contract. If your salespeople don't do this, they will let you sign the contract directly, which will cause you related losses. You can ask the sales office or the developer to compensate or solve the problem. . .
