Which intermediary company is the best to buy second-hand houses in Chengdu? thank you

I just bought a second-hand house this month, lamenting how expensive it is. In fact, real estate agents are all the same. In Chengdu, Yicheng Real Estate is the largest, but in addition to the agency fee for buying a house, it has to charge the landlord a fee of 1. 15%, so the price of Yicheng Real Estate is higher, because the landlord will not lose money. He added the agency fee to the house price. Everything else is full house, chain home, one plus two. In fact, the houses are all interoperable, and they are all possible. The agency fee is also negotiable. I suffered this loss at that time and paid at least 500 more. Besides the intermediary company itself, the attitude of the intermediary itself is also very important. It depends on whether they are willing to run errands for you. Some agents don't tell you about a good house, and it's annoying to fool you all the time Also, don't pay a deposit first after seeing the house! Be sure to see the landlord before handing it in! I was going to book one of the houses, but later I saw a better one, so don't worry, take your time ~ I wish you a good house ~
