The mortgage market in 2024 has gone through several distinct phases, marked by a gradual decline in rates following the increases of previous years. The rates displayed by banks have decreased quarter after quarter, with average rates over 20 years dropping from around 4% at the beginning of the year to significantly lower levels by the end of the period. However, behind this overall trend, the reality of offers varies greatly depending on the borrower’s profile and the institution approached.
Segmentation of Borrower Profiles: The True Differentiating Factor Between Banks
The question “which bank offers the best rate?” has lost some of its relevance in 2024. Major retail banks like BNP Paribas, Crédit Agricole, or Société Générale have adopted very segmented internal grids. So-called “high-balance” profiles (stable income, permanent contract, significant savings, projects exceeding 250,000 euros) benefit from marked discounts compared to the standard rate.

In contrast, applications close to the debt ceiling or with low contributions are offered significantly less favorable conditions, when these banks still agree to finance them. The rate depends more on the profile than on the chosen bank.
This segmentation means that a borrower with a solid application can obtain a discount of several dozen basis points at an institution that displays a relatively unattractive average rate. Conversely, a first-time buyer with limited contributions may sometimes find better conditions at a regional mutual bank that is less visible in online comparisons. Conducting a comparison of mortgage rates tailored to one’s personal situation remains the most reliable approach before any negotiation.

HCSF Exemption Margins: An Overlooked Lever That Distorts Comparisons
The High Council for Financial Stability (HCSF) has imposed a debt limit set at 35% of income for several years. In 2024, the flexibility margins allowing banks to exceed this threshold have been confirmed and expanded, particularly for first-time buyers’ primary residences and high incomes.
The problem: these exemption margins are used very unevenly across institutions. Two banks displaying the same rate may have radically different policies on this point.
- Some banks use nearly their entire quota of exemptions from the first quarter, then close access to atypical profiles for the rest of the year.
- Others reserve these margins for strategic applications (high income domiciliation, wealth to capture) and systematically refuse modest first-time buyers.
- Some mutual institutions adopt a more regular approach, distributing exemptions throughout the year.
Comparing only nominal rates ignores these differences in actual access to credit. An attractive rate on paper is worthless if the bank refuses the application or imposes insurance and guarantee conditions that inflate the total cost.
APR and Additional Fees: Where the True Cost of Mortgage Credit Lies
The nominal rate remains the most publicized indicator, but the APR (Annual Percentage Rate) includes all mandatory fees related to the loan. The difference between the two can reach several tenths of a point depending on the banks.
Factors That Widen the Gap
Borrower insurance is the most variable item. Some banks offer competitive group contracts for young and healthy profiles, while others apply high rates that negate the advantage of a low nominal rate. Insurance can represent a third of the total cost of credit.
Application fees, guarantee fees (mortgage or guarantee type Crédit Logement), and early repayment penalties also vary significantly. A broker or a comparator that only displays the nominal rate gives a distorted picture of reality.
Loan Duration and Its Impact on Total Amount
A 25-year loan mechanically displays a higher rate than a 15-year loan. But beyond the rate, it is the total cost of interest that skyrockets with the lengthening of the term. Reducing the duration by a few years can generate savings of several thousand euros, even with a slightly higher rate.

Online Banks vs. Traditional Banks: A Gap That Is Closing on Rates but Not on Service
Online banks have long displayed rates significantly lower than those of traditional networks, thanks to lower structural costs. In 2024, this gap has narrowed. Retail banks, eager to regain market share after a difficult 2023, have aggressively adjusted their rates for the profiles they target.
The difference is now played out on other grounds. Online banks generally offer reduced or no application fees and a quick digital subscription process. Traditional banks provide more personalized support, face-to-face negotiation capacity, and, above all, access to HCSF exemption margins that online banks do not always utilize.
For a standard application without particular difficulties, online banks remain competitive. For an application that requires detailed analysis (atypical contribution, mixed employee-independent income, rental investment), traditional banks have more leeway.
- Online banks: advantage in additional fees and processing speed, but less flexibility on complex applications.
- Traditional banks: adjustable rates through direct negotiation, access to regulatory exemptions, often requiring income domiciliation.
- Regional mutual banks: intermediate positioning, sometimes more open to local first-time buyers with modest contributions.
The available data do not allow for designating an absolute winner. The best mortgage rate in 2024 primarily depends on the application presented, then on the internal policy of each institution at the precise moment of the request, and finally on the actual APR once all fees are included. Comparing offers based solely on the nominal rate remains an incomplete approach that can be costly over the total duration of the loan.
