If you want a family apartment the monthly price will increace. Prizes are depending on size, standard and how close to the city you want to live.
UiB housing
Guest housing in UiB owned apartments/flats.
It will be your contact at the faculty who does all the arrangements for these flats as it is the faculty which is the tenant on your behalf. Renting these flats will cost you from about 4500 NOK a month for a single flat with one bed and shared bathroom, to 15 500 NOK a month for a family apartment.
Even though your contact at the faculty will have to do the arrangements, you can still look for available options (and prices) within your preferred timeframe.

Sammen (The Student Welfare Organisation in Bergen).
Students are the prioritised group for Sammen, but if there is available accommodation it may be possible to rent for a shorter period of time. The prices for housing can vary from about 2000 NOK a month for a single room with shared bathroom, to about 9000+ NOK a month for a family apartment. Sammen is the cheapest option for flats in Bergen, but unfortunately they are not always that easy to get.

UIB "Inner market" housing.
At UiB there is what we call an "Inner market" for flats and apartments. This is a marketplace where employees register housing for rent, and where people within the UiB organisation advertise for housing wanted. The prices on the housing announced here will vary depending on size, shared/not shared facilities, distance from the city - and so on. The prices already mentioned above are representative for the prices of these flats.
If you find housing of interest you contact the person listed in the advertisement directly and make a private arrangement.
