I am from other places, I want to buy a second-hand house in Harbin, and I want to entrust an intermediary company, but I don't know which company is good, so I am in a hurry. What procedures are needed, I bought a second-hand house in Nianjia Real Estate. I didn't know where to go at that time. I was introduced to this house. I think the house I bought in the early stage is not bad, and the intermediary is also working hard to find it for me. Because I'm also from other places, I'm in a hurry to register in Harbin. What procedures should I go through after buying a house later? The person who helps me do this will follow me. Helped me a lot, and I just think they are also very responsible and the after-sales service is in place. I think you are relieved to buy a house in his house. Let me tell you his home address, which is opposite Nangang branch. This is a big brand. If you look for it, you should find it. I hope you can buy a satisfactory house.
