Many buyers will find an intermediary when buying a house. The main significance of intermediary is to provide convenience for buyers and sellers, and will also charge a certain intermediary fee. However, if loan service fees or other unreasonable charges are found, they can be handled by relevant departments or their legitimate rights and interests can be safeguarded through legal channels. The normal agency fee is to provide customers with housing resources, including the service fee generated in the process of house viewing and negotiation, but the loan fee is not included, so the loan service fee can be directly refused. At present, the service fees charged by most intermediaries in cities are borne by buyers and sellers, and the service fees charged by residential sales generally do not exceed 1%. If the intermediary wants to provide other related services, the parties can choose voluntarily, or it can be clearly stipulated in the signed intermediary contract. Therefore, when looking for an intermediary to buy a house, you must read the intermediary contract clearly.
