You can buy a second-hand house without going through an intermediary, but if you don't trust the transaction object or worry about risks, it is a relatively safe plan to go through an intermediary. In addition, if you sign a brokerage contract with an intermediary, it is best not to trade privately. This is a question of honesty, and people have also paid their own labor. In addition, if the intermediary knows, it can ask you to pay the intermediary fee. The specific operation steps are as follows:

1. Go to the real estate bureau to sign the stock house sales contract and supplementary agreement, stipulate the responsibilities of both parties and the expenses paid by them, and go to the real estate bureau to check the price after signing the stock house sales contract.

2. The seller holds the stock house sales contract, ID card, real estate license, etc. Go to the local tax bureau to file tax returns, pay personal income tax, business tax and so on.

3. The buyer and the seller go to the real estate bureau for fund custody, and deposit the down payment into the account designated by the real estate bureau when buying a house. It should be noted that if you choose a bank to handle the loan, it is best to deposit it in the account of the real estate bureau in this bank to avoid the trouble of loan approval. Keep the escrow agreement for you and withdraw it later.
