This is not really true. Immigrants are not being appointed housing in Stockholm City and they do not contribute to the housing problem. Most parts of Sweden actually have problems with housing for the opposite reason, urbanization is pushing big parts of the population into the big cities so there's rather cheap housing in the more "rural" parts.
The issue with housing is Stockholm has existed way before it became popular to blame all problems on the immigrants.
