Finanssivalvonta Loan Ceiling (Enimmäisluototussuhde)

The Finnish Financial Supervisory Authority (FIN-FSA) caps residential mortgages at 90% of collateral value for standard purchases, and 95% for first-time buyers (ensiasunnon ostajat), requiring 5% to 10% cash equity.

ASP (Asuntosäästöpalkkio) State Support Program

The government-backed ASP scheme for buyers aged 18 to 44 requires saving 10% of property purchase price over at least 8 calendar quarters. In return, the state provides a free deficiency guarantee (valtiontakaus), interest rate subsidy covering 70% of interest exceeding 3.8%, and preferential bank loan margins.

Preponderance of 12-Month Euribor Floating Mortgages

Over 95% of Finnish mortgages are variable rate loans indexed to the 12-month Euribor plus a bank margin (typically 0.40% to 0.85%). Borrowers can purchase interest rate caps (korkokatto) from lenders for rate shock protection.

FIN-FSA 6.0% Serviceability Stress Test

Finnish credit institutions must test borrower debt servicing capacity assuming a 6.0% interest rate and a maximum 25-to-30-year amortization schedule, verifying that monthly loan obligations do not exceed 40% to 45% of net household income.
