Masteri...?

Hei kaikille!
I'm a foreign student graduated from an ammattikorkeakoulu, now I want to apply for master degree. I studied Business Administration, so I guess I have to choose the same area with the master degree. Because I don't have any working experiences, which universities are best for me? I'm also considering the costs. Because I know that some area (esim. Helsinki, Turku,...) the housing rent is very expensive, could you give some suggestion which area is less expensive to live in Finland, at the same time a foreign student can study master degree? I know that those universities in small cities don't have much choices, although less expensive to live, do you have any suggestions in my situation?
Kiitos avusta! :)
