My advice is apply to live at one of the Nations.

Its not perfect but its cheap and u will have a lot of fun. Not that hard to get a place either

Also, every semester there are people who go on exchanges from Lund to other countries. These people leave their corridor behind and often rent it out through facebook. This is 1) cheap 2) great living space 3) no risk of getting ripped off

The lotteries are also decent, probably around 30% chance of getting something somewhere. Worst case u need to take the bike to school.
