First of all, whether a university must stay depends on the regulations of the university and the country and region where the students live. In some countries and regions, universities may require students to stay on campus, at least for a certain period of time. This is usually to facilitate students' study and life and ensure their safety. For example, in some university towns or boarding universities, students may be required to live on campus.
In other countries and regions, universities may not have such regulations, and students can choose to rent a house off campus or live at home. In this case, students need to find their own houses and rent their own houses, and they need to abide by local rental regulations and contracts.
Secondly, whether it is necessary to pay accommodation fees when going out to rent a house depends on the university where the students are located and the provisions of the rental contract. In some universities, if students choose to rent a house off campus, they may have to pay extra for accommodation, which may be higher than that on campus. However, in some other universities, students may not need to pay extra accommodation fees, because they can choose to live at home or rent a house off campus without paying extra fees.
The specific cost of renting a house depends on the geographical location of the house, the type and facilities of the house, the length of the lease contract and other factors. For example, if students rent a house in a big city or a busy area, the rent may be higher; If students choose to rent luxury apartments or detached villas, the rent may also be higher.
Generally speaking, the question of whether a university must live and whether it is necessary to pay accommodation fees when going out to rent a house needs to be analyzed and answered in detail according to the country and region where the students are located, the regulations of the university and the stipulations of the lease contract. For students, the best choice is to choose their own accommodation according to their own needs and economic ability.
