Xiao Gu was an MBA student at Tsinghua University. In order to facilitate his study and work, he and his classmates shared a two-bedroom house in Dongwangzhuang Community not far from Tsinghua University when they enrolled in 2015. At the end of August this year, it seems that the land rent contract will expire last year. Xiao Gu and his classmates want to find another new place to live. This matter is the responsibility of Xiao Gu to find a new address and talk about price and other matters with the new homeowner.
Due to the large demand, the housing is very tight, which leads to the relatively high housing prices in Dongwangzhuang: the monthly rent for one-bedroom is around 1600-2000 yuan, and the monthly rent for two-bedroom is between 2100-2800 yuan. The specific price depends on the decoration of the house, the facilities, equipment, and the matching of the household appliances. Of course, it is also related to the negotiation results between the lessee and the tenant.
This morning, Xiao Gu received a call from the real estate agency to let him see a new listing. According to the real estate agent, the homeowner plans to rent 2,800 yuan a month to Xiao Gu, the real estate agency believes that the monthly rent of 2,500 yuan is worth, the lowest is only 2,300 yuan. Due to the understanding of the real estate agent during the recent period of finding a house, Xiao Gu thought that his words were still worthy of trust, so he decided to go to the house and negotiate with the homeowner about the house price. If you are Xiao Gu, how would you negotiate with the homeowner?
