You repay your mortgage over twenty or twenty-five years. Over this duration, even a difference of a few tenths of a point in the rate radically changes the total cost. Obtaining the best rate for a mortgage in 2024 is not just about comparing online rates. The difference lies in how your application is perceived by the bank receiving it.
What the bank calculates before setting your mortgage rate
The rates displayed by banks are starting grids, not firm offers. Each institution then applies a discount or a surcharge based on the borrower’s profile. Understanding this mechanism allows you to know where to act.
The first criterion is the risk of default. The bank looks at your net income, its stability, and especially your remaining disposable income after repaying all expenses. A debt-to-income ratio below the regulatory threshold is not enough: a high remaining disposable income weighs more than a low debt-to-income ratio.
The second criterion is less known. Banks set their rates based on the 10-year OAT, the government bond that serves as a reference for calculating their margins. When this index falls, banks have more room to offer attractive rates. In 2024, the decline of the 10-year OAT allowed for significant decreases, with average rates over 20 years falling below 4% as early as spring.

Personal contribution and loan duration: the two levers that influence the rate
Why do two borrowers with identical incomes receive different rates? The answer often lies in two variables: the amount of the contribution and the chosen duration.
The contribution, a signal of creditworthiness
A contribution covers at least the notary and guarantee fees. But beyond this minimum, each additional tranche reduces the risk for the bank and mechanically improves the proposed rate. Aiming for a contribution greater than 10% of the property’s price opens the best pricing grids.
In 2024, the average amount of mortgage loans decreased by 7% compared to the previous year, according to the ACPR. This decline is partly explained by the fact that borrowers had to mobilize more savings to compensate for the rise in rates. Banks have therefore mechanically favored applications with a solid contribution.
The duration, a double-edged variable
A 15-year loan costs less in interest than a 25-year loan; it’s arithmetic. But shortening the duration raises the monthly payments and can inflate the debt-to-income ratio.
The best rate is often obtained on the shortest duration that your budget can realistically support. In other words, you need to find the balance between an affordable monthly payment and a duration that remains attractive to the bank.
Mortgage application: three points that banks scrutinize as a priority
Beyond the major financial parameters, the quality of the application sways the decision. Here are the concrete elements on which the selection is made.
- The account management over the last three months: no overdrafts, no rejected direct debits. A recent banking incident can be enough to downgrade your application to a higher rate grid, even if your income is comfortable.
- Professional stability: a confirmed permanent contract remains the standard. Self-employed individuals must present at least two, if not three, balance sheets with stable or increasing income. Profiles in a trial period are almost systematically excluded from the best rates.
- The absence of ongoing consumer loans: each consumer loan reduces your borrowing capacity and increases your debt-to-income ratio. Paying off a car loan or a revolving credit before submitting a mortgage application can save several tenths of a point on the rate.
A complete application, with no missing documents, submitted in a clear format, also speeds up processing. Banks handle hundreds of requests. A well-presented application reduces the risk of it being put on hold or sent back for additional information.
Mortgage broker: in what cases does it really make a difference
Using a broker is not a universal reflex. However, for certain profiles, the rate difference obtained justifies the brokerage fees.
The broker negotiates with several banks simultaneously. They know the current commercial policies, which vary from quarter to quarter. A bank looking to attract first-time buyers may offer a more aggressive rate than an institution already saturated with applications.
The broker also provides a timing advantage. In 2024, the downward trend in rates has been gradual. Rates sometimes changed from one week to the next. A broker with real-time agreements can seize a favorable window that the individual, alone with their bank advisor, may not perceive.
Have you ever noticed that the rates displayed online never exactly match the offer you receive? This is precisely because the final rate depends on the intersection of your profile, the bank’s policy at that moment, and the negotiation capacity of the application. The displayed rate is a theoretical ceiling, not a promise.
Borrower insurance: the hidden cost that weighs as much as the rate
Focusing solely on the nominal rate is a common mistake. Mortgage insurance represents a significant portion of the total cost of credit, sometimes as much as the interest itself for younger profiles.
Since the Lemoine law, you can change borrower insurance at any time, without fees and without waiting for the anniversary date. Comparing insurance contracts can reduce the overall cost of credit more significantly than a gain of 0.1 points on the rate.
The classic reflex is to accept the group insurance proposed by the bank. It is easy to subscribe to but rarely the cheapest. Delegated contracts, taken out with external insurers, often offer more competitive rates, especially for borrowers under 40 and non-smokers.
The best mortgage rate in 2024 is not obtained with a single lever. It is the combination of a well-prepared contribution, an impeccable application, a calibrated duration, and optimized insurance that produces the result. Every tenth of a point saved over twenty years translates into several thousand euros less in the total cost of the loan.
