Getting a mortgage in 2024 is not just about comparing rates. The rate displayed by your bank only represents part of the actual cost of borrowing. Insurance, guarantees, repayment duration, regulatory rules: each parameter impacts the final bill and even the feasibility of the project.
The 35% effort rate rule: what the bank really calculates
Before looking at rates, you need to understand the filter that determines whether your application is accepted or not. The High Council for Financial Stability (HCSF) imposes a maximum effort rate of 35%, including borrower insurance. In practical terms, the total monthly payment (principal, interest, insurance premium) must not exceed 35% of your net income.
This cap is generally accompanied by a duration limited to 25 years, extended to 27 years for operations with a deferred entry (purchase in VEFA or construction). Banks have a margin of flexibility on 20% of their quarterly production, with priority given to primary residences and first-time buyers.
Do you meet the 35% criterion? Meeting the threshold does not guarantee loan approval. Each institution applies its own criteria for solvency, professional stability, and the quality of the financed property. A file technically compliant with HCSF rules can be rejected if the bank deems the profile too risky.

Borrower insurance: the item that most buyers underestimate
Why focus on insurance when discussing credit? Because borrower insurance is included in the effort rate. It directly reduces your borrowing capacity.
The contract proposed by your bank (group contract) is not necessarily the cheapest. Since the Lemoine law, you can change borrower insurance at any time, at no cost and without waiting for an anniversary date. Delegating insurance, meaning subscribing with an external insurer, generates significant savings over the total duration of the loan.
Comparing borrower insurance before signing the loan offer can shift a file from rejection to acceptance. If your effort rate is close to 35%, a lower insurance premium can sometimes bring you back under the threshold.
Points of caution regarding the insurance contract
- Check the guarantees required by the bank (death, disability, incapacity to work) and ensure that the delegated contract covers them at the same level.
- Look at the insured amount: for a purchase by two, the bank may require different coverage based on each co-borrower’s income.
- Anticipate the health questionnaire. Certain pathologies lead to surcharges or exclusions that alter the actual cost of the credit.
PTZ in 2024: an expanded scheme but criteria to verify
The zero-interest loan has seen a notable expansion. The PTZ can now finance new housing throughout the French territory, including apartments and individual houses. This measure applies to loan offers issued until December 31, 2027.
Eligibility no longer relies solely on the reference tax income. For offers issued since April 2025, the administration considers the highest amount between the household’s reference tax income and the total cost of the operation divided by nine. This rule can exclude households whose incomes seem to be below the ceilings.
Before preparing your application, calculate in both directions. A high operational cost can render you ineligible even with modest incomes. This is a common trap for buyers targeting a new property in a tight area.
Building a solid mortgage application: the criteria that matter
The bank analyzes your application from three angles: the stability of your income, the quality of your financial management, and the coherence of your real estate project.
Bank account management
Bank statements from the last three to six months are scrutinized. Recurring overdrafts, rejected direct debits, or disproportionate spending relative to income weaken the application. Stabilizing your accounts several months before the loan request is not a trivial piece of advice; it is a real filter used by credit analysts.
Personal contribution and loan duration
The personal contribution covers at least the ancillary costs (notary fees, guarantees, application fees). The higher the contribution, the lower the amount borrowed, which mechanically reduces the total repayment cost and improves the proposed rate.
The duration of the loan plays a symmetrical role. Borrowing over a shorter duration reduces the total interest cost but increases the monthly payment. The trade-off between duration and monthly payment depends on your effort rate and your residual saving capacity.
- Contribution of 10% or more: a positive signal for the bank, better negotiable rate.
- Professional stability: a permanent contract outside the trial period remains the simplest profile to finance. Self-employed individuals must present several positive financial statements.
- Sufficient disposable income: beyond the effort rate, the bank checks that your income after the monthly payment covers your current expenses.
The advantageous mortgage in 2024 is not the one that displays the lowest nominal rate. It is the one whose total cost (interest, insurance, guarantees, application fees) remains controlled throughout the repayment period, with a structure adapted to your actual situation.
