Obtaining a mortgage depends on a set of measurable criteria that banks cross-reference to evaluate each application. Debt-to-income ratio, personal contribution, job stability, cost of borrower insurance: these variables do not all carry the same weight depending on the institution. Understanding how they interact allows one to anticipate the bank’s decision even before submitting an application.
Eligibility Criteria for a Mortgage: Relative Weight of Banking Variables
Banks do not apply a single grid. Some criteria are regulatory (imposed by the HCSF), while others fall under the commercial policy of each institution. The table below distinguishes between these two categories.
| Criterion | Nature | Threshold or Common Requirement |
|---|---|---|
| Debt-to-Income Ratio | Regulatory (HCSF) | 35% maximum, including insurance |
| Maximum Loan Duration | Regulatory (HCSF) | 25 years in principle |
| Personal Contribution | Banking Policy | Often at least 10% of the project amount |
| Job Stability | Banking Policy | Permanent contract, civil servant, or verifiable regular income |
| Account Management | Banking Policy | Absence of repeated overdrafts and incidents |
| APR below the usury rate | Regulatory | APR must not exceed the quarterly threshold published by the Banque de France |
The distinction between regulatory constraint and internal criterion is rarely made explicit in refusals. An application may comply with the HCSF rule of 35% debt-to-income ratio and still be denied because the bank deems the remaining disposable income insufficient or the account history too irregular.

Usury Rate and APR: The Ceiling That Blocks Applications
The usury rate sets a legal ceiling on the APR (annual percentage rate) that the bank can offer. This APR aggregates the nominal rate of the mortgage, the cost of borrower insurance, application fees, and guarantee fees.
A borrower whose medical profile or age leads to a higher insurance premium sees their APR rise mechanically. If this APR exceeds the current usury rate, the bank cannot legally grant the loan, even if all other criteria are met.
Why Borrower Insurance Weighs Heavily in the Calculation
Insurance represents a significant part of the total cost of credit. For profiles considered risky by insurers (chronic conditions, advanced age), the premium can be enough to push the APR above the usury threshold.
The Lemoine Law, in effect since 2022, offers two concrete levers:
- The ability to change borrower insurance at any time, without fees or penalties, which allows for a reduction in the overall cost of credit after signing or even during the application process if a cheaper offer exists.
- The elimination of the medical questionnaire under certain conditions regarding the amount borrowed and age at the end of the loan, which removes the risk of higher premiums or exclusion for health reasons in these specific cases.
- Facilitated competition among insurers, which drives prices down for standard profiles and opens up solutions for profiles previously denied.
An application initially denied for exceeding the usury rate can thus become eligible by substituting the bank’s group insurance with a less expensive insurance delegation.
Debt at 35%: What the HCSF Rule Doesn’t Say
The ceiling of 35% debt-to-income ratio including insurance remains the structuring norm in 2026. This rule from the High Council for Financial Stability governs nearly all banking decisions and explains a significant portion of refusals.
The calculation appears simple: monthly credit charges divided by monthly income, multiplied by one hundred. In practice, banks include all ongoing credits (consumer loans, other mortgages, car leasing in some cases) in the charges.
The Remaining Disposable Income as a Complementary Criterion
A borrower with a 34% debt-to-income ratio and modest income may be denied a loan if their remaining disposable income (income minus fixed charges) is deemed too low to cover current expenses. Conversely, a high-income profile slightly exceeding 35% may benefit from an HCSF exemption, which banks are allowed to grant in a limited proportion of their applications.
Remaining disposable income is as important as the debt-to-income ratio for low-income earners. Two applications at the same debt-to-income percentage do not have the same strength if one leaves a few hundred euros of margin and the other more than double.
Income Stability and Account Management: The Signals the Bank Reads First
Feedback from brokers in 2026 converges on a finding: banks have become slightly less rigid regarding the level of contribution, but vigilance regarding income stability and banking management remains strong. A permanent contract outside the trial period or a civil servant status remains the expected standard.
For freelancers and self-employed professionals, banks generally require several years of accounting statements. The regularity of revenue is weighted more than its absolute amount.
What Your Bank Statements Reveal
The last three to six months of statements are scrutinized. Banks look for:
- Recurring overdrafts, even of small amounts, which signal tight cash management.
- Rejected direct debits, which may indicate payment difficulties or poor anticipation of charges.
- Gambling or online betting expenses, sometimes considered a behavioral risk factor by certain institutions.
- Residual savings after paying charges, which demonstrate an ability to absorb a financial unforeseen event.
A listing in the FICP (file of incidents of repayment of loans to individuals) leads to an almost systematic refusal. Checking one’s situation with the Banque de France before any application avoids unnecessary processing.
Preparing a mortgage application takes several months. Cleaning up accounts, paying off a consumer loan to reduce the debt-to-income ratio, comparing borrower insurance thanks to the Lemoine Law: these actions concretely modify the variables that the bank measures. A refusal is not final if the criteria that caused it can be corrected before a new application.
