How Swedish mortgages work

Basics of bolån, interest, fixed periods, and what banks assess before pre-approval.

15 January 2026 · 1 March 2026

A bolån (mortgage) is a loan secured against your home. For most first-time buyers it is the largest debt they will take on — so understanding the terms before bidding pays off.

Interest and monthly cost

  • Nominal rate is the bank’s headline rate; effective rate includes fees.
  • You can choose a variable rate (tracks the market) or a fixed rate for a binding period.
  • Monthly cost depends on interest, amortization, and any bank fees.

Binding period

The binding period is how long your agreed rate applies. Longer fixes often mean a higher rate but more predictability. Many borrowers split the loan across different periods.

Pre-approval and loan-to-value

Banks issue lånelöfte (pre-approval) based on income, existing debt, and buffer savings. Loan-to-value is the loan relative to the property value — higher leverage triggers stricter amortization rules (see the budget article).

Practical steps

  1. Gather payslips and an overview of savings and debts.
  2. Compare pre-approval and rate offers from at least two banks.
  3. Stress-test monthly cost at today’s rate and at higher rates.
