A couple with two permanent contracts, a 15% contribution, and a well-prepared project is offered a rate of 3.9% over 20 years. The neighbor, with a comparable profile, signs at 3.4% with another bank. The difference represents several thousand euros over the total duration of the loan. Choosing the best mortgage rate in 2024 is not a matter of luck, but of concrete preparation of the file and a competitive approach among banks.
HCSF exemptions and disposable income: what banks really accept in 2024
It is widely reported that the debt-to-income ratio is capped at 35% and the repayment period is limited to 25 years. These rules from the High Council for Financial Stability remain in effect. What is less visible in competing guides is the actual use of the leeway allowed for banks.

During hearings before the Finance Committee of the National Assembly at the end of 2024, several institutions confirmed that they are now fully utilizing the 20% exemptions authorized by the HCSF. Specifically, if you are a first-time buyer with a comfortable disposable income after expenses, a bank may agree to finance you beyond the 35% debt threshold.
To find out how to choose the best mortgage rate, you start by calculating your disposable income, not just your gross debt ratio. Some banks consider what remains after monthly payments and fixed charges, and this amount weighs as much as the debt ratio in the final decision.

The Bank of France also notes in its statistics on consumer credit that the rate of rejected applications has decreased since the end of 2024, after a peak in 2023. The increase in wages and the minimum wage has mechanically improved the debt profile of many households, opening doors that many still believe are closed.
Mortgage rates: concrete levers to negotiate downwards
Getting a good rate is not just about having good income. Banks are looking for new clients and make decisions based on specific criteria. Here are the levers that really move the needle in 2024.
- Bank domiciliation: agreeing to transfer your current accounts and savings to the lending bank remains the most powerful lever. Some institutions offer a significant discount on the rate in exchange for a commitment to domiciliation for several years.
- Personal contribution: beyond the minimum threshold expected by the bank, every additional point of contribution reduces perceived risk. A contribution that covers notary fees and part of the property places the file in a more favorable risk category.
- Borrower insurance: delegating insurance (choosing an external contract rather than the bank’s) helps reduce the overall cost of the loan. Since the Lemoine law, you can change your loan insurance at any time, which provides a negotiation argument right at signing.
- Loan duration: shortening the duration by a few years lowers the proposed rate. A 15-year loan consistently shows a lower rate than a 25-year loan, sometimes significantly.
Putting banks in direct competition
Submitting your file to only one bank means accepting its price without discussion. It is recommended to approach at least three institutions, ideally five. Presenting a quantified competing offer forces the bank to align or justify its difference.
The mortgage broker plays this role of competition on your behalf. Their interest: they know the internal pricing grids of partner banks and understand which institution favors which borrower profile at any given moment. It is noted that responses vary on this point depending on the regions, but in tight markets, going through a broker often saves time and a few tenths of a point.
Public guarantee and zero-interest loan: schemes that change the real cost of credit
The nominal rate displayed is only part of the equation. Two public schemes radically change the real cost of a mortgage in 2024.
The zero-interest loan (PTZ), reserved for first-time buyers under a resource ceiling, finances part of the purchase without interest. Combining a PTZ with a main loan reduces the weighted average rate of the entire financing. This results in a total cost significantly lower than what the main loan rate alone indicates.
Public guarantees (such as Visale for certain profiles, or guarantees from organizations like Action Logement) help avoid mortgages, which represent a significant cost at entry. Eliminating these fees frees up budget to strengthen the contribution or shorten the loan duration.
Compare the APRC, not the nominal rate
The annual percentage rate of charge (APRC) includes interest, borrower insurance, processing fees, and guarantee fees. Two offers with the same nominal rate can present very different APRCs. It is the APRC that reflects the real cost of credit, and it is what should be compared primarily.
Mortgage application: signals that reassure the bank
A bank reads a file as a risk assessment. Certain signals trigger an aggressive offer, while others hinder negotiation.
Bank statements from the last three months are scrutinized. A recurring overdraft, even modest, sends a negative signal. Conversely, regular savings (even small amounts) demonstrate management capacity. It is advised to stabilize your accounts for at least three months before submitting a file.
Professional stability matters more than the gross income amount. A permanent contract validated after the trial period remains the expected standard. For freelancers, presenting three stable or growing financial statements compensates for the absence of an employee contract.
Finally, the absence of ongoing consumer loans reduces the debt ratio and simplifies the reading of the file. Paying off a car loan or a revolving credit before applying for a mortgage can save one or two points on the debt ratio, which is sometimes enough to unlock a more competitive offer.
The best mortgage rate in 2024 is not found online in a fixed comparator. It is built in advance, file by file, bank by bank, by leveraging existing exemptions and presenting a profile that the lending institution wants to attract.
