When you look at your home, how many rooms are there and how many do you use regularly. Do you find yourself mostly using 2 rooms? If that is the case then you are essentially paying for a glorified storage space, so it might be time to downsize.
I lived in a decent sized house in the US but when I moved to Sweden, I moved into a 25 sqm space and I later downsized to 19 sqm. However, I found this much too small and I recently moved into 23 sqm space that is just the right size. A one bedroom apartment in Stockholm can cost between 10,000 – 15,000 SEK/ 1,000-1,500 USD, depending on location.
In Sweden, as a student, you are allowed subsidized housing through various student unions. You just have to queue for them and whoever has the most days get them. The subsidizations vary throughout the country, my housing is 50% less than the going rental rate for the area.
