The cap
When a mortgage is granted, the bank must make sure the loan-to-value is at most 90 per cent of the home's market value (section 4). So you need at least 10 per cent in cash. When an existing loan is increased, the cap is 80 per cent (section 5). Before 1 April 2026 it was 85 per cent, in Finansinspektionen's guidelines.
Amortisation
Above 50 and up to 70 per cent loan-to-value the loan must be amortised each year by at least 1 per cent of the highest loan amount since the latest valuation; above 70 per cent by at least 2 per cent (section 7). The extra requirement – another 1 per cent when loans exceeded 4.5 times gross income – is not in the new act.
Existing loans do not change by themselves: borrowers who want the new terms must agree them with the bank (government press release, 5 March 2026).
From the law
«När en bostadskredit lämnas ska kreditgivaren se till att belåningsgraden blir högst 90 procent.»
Background
Parliament passed the act on bill 2025/26:119 (committee report 2025/26:FiU36). It replaces Finansinspektionen's regulations and guidelines on amortisation and the cap (FFFS 2016:16, 2016:33 and 2020:3). Banks still do their own credit assessment.
Laws change. Always check the version in force and consult a lawyer about your own case. The Swedish text of the law is the authoritative one.
