It's it possible to get a homestay in Oslo as international student ?

I am an african student about to join the Norvegian University of Life Sciences in Oslo, but paying for accomodation in the campus is going to be tuff for me.
So I am looking for a homestay,  where I can pay a certain amount per month or eitheir take care of the house, pets, or kids while going to school.
Please if there's someone who can give me any informations dont hesitated. I still have time.
Thanks.

Where in Africa are you from?
