Hello dear Erasmus students!
Here is a text that answer most of the questions we usually receive :
First, the easiest way to have a contract for one semester only is living in an UCL kot. Even thought they're currently full (even on the waiting list), new rooms will be available at the beginning of September (some Belgian students change their mind and finally don't study in LLN). We do not guarantee that there will be room for everybody but just keep in mind that this option isn't dead yet.
Secondly, for private kots, most of the owners are looking for 10 months or 12 months contracts. Since they still have a month to find tenants, they're currently expecting Belgian "latecomers" or exchange students coming in LLN for an entire academic year. You will thus have more chances to find a private kot later.
Moreover, trying to make a one-year-tenancy deal with students coming during the second semester will be pretty difficult since the vast majority of them won't be on our Facebook group before December.
Finally, and once again this is no guarantee, this is not such a big deal if you do not find any accommodation before your arrival in Belgium. This is of course better and safer if you have one but quite a few students arrived here last year without a place to live and they all eventually managed to find one after a few days.
We hope this will help you in your housing research.
