How am I affected if mortgage rates in Sweden rise significantly?

With a variable rate ("rörlig ränta"), you notice increases immediately – if you have a 3 million loan ("lån") and rates rise 2 percentage points, your monthly cost ("månadskostnad") increases by about 5,000 SEK. Calculate how much you can handle before taking the loan and have a buffer. If you can't manage payments, you can apply for temporary amortization relief ("amorteringsfrihet") from the bank. In the worst case, the bank may require you to sell if you can't handle interest payments for an extended period. This is why stress-testing your budget is crucial.
