How does having multiple homes and mortgages work in Sweden?

You can have mortgages ("bolån") on multiple homes – primary residence ("permanentbostad"), vacation home ("fritidshus"), or investment properties ("investeringsobjekt"). The bank adds up your total debt burden ("skuldbörda") and all costs in their KALP calculations ("KALP-kalkyl"). Amortization requirements ("amorteringskrav") apply to each home based on its value and your debt level. Interest deductions ("ränteavdrag") apply to all your mortgages ("bolån") regardless of number of homes. Keep track of the overall picture and be realistic about what you can actually afford. Don't overextend yourself.
