There are a lot of companies that provide regular (non-student) apartments. Most of the websites are in Swedish, but you can use translate.google.com or Google Chrome to translate them. It is not always a perfect translation but it can help you find their contact information.
Most companies require you to have a swedish personal identity number ("personnummer"), but a few does not. If a Swedish personal identity number is required when you register, please contact the landlord by phone or e-mail and they might accept your registration anyway (this, however, differs from company to company). Out of the companies which does not require a personal identification number, Victoria park is the one that most often have vacant apartments.
Municipal housing companies uses a queue point system where you get one queue point for every day you are registered at their website. When an apartment is available its usually the applicant with the highest amount of points that gets it. These companies usually has the largest amounts of apartments so it is a good idea to register with these companies as soon as possible, preferably as soon as you start to consider studying at Linköping university.
Private landlords usually don't use queue points. After registering you simply apply for apartments by a letter of interest and the landlord will consider whether you are suitable as a tenant or not.
If you are willing to commute you might find it easier to find housing. In the start of the autumn semester there are thousands of new students looking for somewhere to stay and they all want cheap, small flats close to the university. Therefore it is a good idea to look a bit outside of Linköping and Norrköping. The housing companies there do seldom have many vacant apartments but you can find quite a few ads at Blocket (a big Swedish ad site) for rooms available for rent or apartments available for sublet. See our guide for commuting here as well as our guide on how to get started with Blocket.
Log on to the landlord’s website regularly to keep your queue points. You will not be offered accommodation automatically – you need to apply actively. For landlords that require you to send a letter of interest on their website we recommend that you read Take Charge for tips on what to remember when applying for accommodation. This information isn't updated regarding new laws of subletting, so please ask us if you have any questions.
