The French mortgage market is going through a paradoxical phase: the production of loans has surged by about 30% in one year after the low of 2023-2024, but the lending conditions remain locked by the HCSF rules. Understanding what is happening behind the displayed rates, the proposed durations, and the actual negotiation margins allows one to distinguish a good setup from a forced financing.
Effort rate and loan duration: the real constraints of the market in 2025-2026
Competitors elaborate extensively on the types of loans or the subscription steps. However, they quickly gloss over the regulatory framework that conditions everything else. The 35% debt-to-income ratio set by the HCSF remains the structural barrier of the market, confirmed in March 2026.
The average effort rate of borrowers is around 30%, which means that most accepted files already consume nearly all of the authorized margin. Banks have some flexibility for certain profiles (first-time buyers, investors), but they do not use it systematically.
At the same time, half of new loans reach 25 years or more. This trend towards long durations offsets the rise in prices and rates, but it mechanically increases the total cost of credit. The table below illustrates the gap between theoretical parameters and observed reality.
| Parameter | Regulatory framework (HCSF) | Observed practice (2025-2026) |
|---|---|---|
| Maximum debt-to-income ratio | 35% | Average around 30% |
| Maximum duration | 25 years (27 years for new builds with deferred payment) | About half of loans at 25 years or more |
| Derogatory flexibility | Up to 20% of quarterly production | Quota rarely fully utilized |
Comparing mortgages on France Immo Express provides an overview of the discrepancies between institutions on these criteria, particularly regarding duration and the rate offered based on the borrower’s profile.
Mortgage for old or new: different financing logics
The production of loans is primarily focused on existing properties. Purchasing in the old market represents the vast majority of financed files, far ahead of new construction or VEFA.
This distribution is not trivial for financial structuring. Buying in the old market involves higher notary fees (around 7 to 8% of the price) and often a renovation budget to integrate. New builds, on the other hand, benefit from reduced fees and options for deferred repayment, which explains the HCSF’s tolerance for durations of up to 27 years in this segment.
Guarantees required by banks
The nature of the property also influences the type of guarantee requested. Banks may require:
- A conventional mortgage, common for older properties needing heavy renovations, as it directly affects the financed property
- A guarantee from a specialized organization (Crédit Logement, for example), preferred for stable employee profiles buying new
- A lender’s privilege, applicable only to already constructed properties, with setup costs lower than a mortgage
The choice of guarantee modifies the total cost of credit by several thousand euros over time. This is often a neglected item in online simulations.
Borrower insurance: an underestimated negotiation lever
Borrower insurance is not legally mandatory, but no bank grants a mortgage without it in practice. Its cost can represent a significant portion of the total cost of credit, sometimes more than the interest itself over short durations.
Since the Lemoine law, the borrower can change insurance at any time without fees or penalties. This possibility remains underutilized. Many borrowers keep their bank’s group contract out of inertia, while delegating insurance to an external insurer can substantially reduce the bill, especially for young and non-smoking profiles.
APR: the indicator that includes everything
The Annual Percentage Rate (APR) aggregates the nominal rate, insurance, application fees, and guarantee fees. It is the only reliable indicator for comparing two loan offers. An attractive nominal rate associated with an expensive group insurance can yield an APR higher than that of a competing offer displaying a higher face rate.
The APR must remain below the usury rate published quarterly by the Banque de France. During periods of rapid rate increases, this ceiling has temporarily blocked certain files, particularly for senior profiles or those with aggravated health risks.
First-time buyers and mortgages: a more selective access in 2026
First-time buyers are facing a double-edged sword. Prices remain high in tight areas, and rates, although down from recent peaks, have not returned to the historically low levels of previous years.
The zero-interest loan (PTZ) remains reserved for the purchase or construction of a primary residence, subject to income conditions. It allows financing part of the project without interest, which alleviates the overall effort rate and can bring a file below the 35% threshold.
- The PTZ only covers a fraction of the total amount: a personal contribution or a complementary loan is still necessary
- Income ceilings vary depending on the geographical area and household composition
- The repayment deferral of the PTZ (up to 15 years depending on the brackets) reduces initial monthly payments but extends the total debt duration
Banks concentrate their HCSF flexibility margin on first-time buyers, but this derogatory envelope is not enough to compensate for insufficient contributions or too low a remaining disposable income. The financial setup must anticipate additional costs (notary, guarantee, moving) to avoid a late refusal.
The mortgage market in 2026 boils down to an operational paradox: banks are lending more in volume, but under conditions that severely filter the files. Loan duration, choice of guarantee, and insurance delegation are the three concrete levers that a borrower can act upon to improve their financing.
