Debt ratio

The HCSF imposes a maximum debt ratio of 35% of your net income.

Understanding mortgages

A mortgage is a loan taken from a bank to finance a property purchase. Monthly payments consist of principal repayment and interest, with the proportion evolving over time through amortization.

The debt-to-income ratio measures your loan payments against your net income. French regulations (HCSF) recommend not exceeding 35% including insurance. Beyond this threshold, banks may reject the application.

Borrower insurance, mandatory for obtaining a loan, averages 0.20% to 0.50% of the borrowed capital. Since the Lemoine law (2022), you can switch insurance providers at any time without fees.
