The average rate for new home loans rose to 3.18% in July 2026 after a relaxation that began at the end of 2024. This shift changes the game for securing a mortgage: borrowing capacity contracts, banks tighten their criteria, and financing strategy becomes a significant negotiation lever once again.
Increase in mortgage rates in 2026: impact on borrowing capacity
Average rates stabilized around 3.23% between February and June 2026, before gradually rising to 3.31% in August, and then between 3.43% and 3.61% in September depending on the duration. This trajectory reverses the downward trend observed since the peak in January 2024, when the average rate reached 3.59%.
The mechanical effect is direct: each increase of 0.20 points reduces borrowing capacity by several thousand euros at a constant monthly payment. For a long-term loan, the additional cost in accumulated interest becomes significant. Borrowers who were waiting for a continued decline now face a less favorable market than in the first half of the year.
We observe that banks adjust their rates with a delay of a few weeks compared to the benchmark rates. A file submitted in early September 2026 no longer benefits from the conditions of June.
This delay argues for strong responsiveness as soon as an offer is obtained: locking in a rate before the next rate revision can represent substantial savings. To compare available offers, the site france-immo-express.eu for credit allows for quick comparison of proposals from lending institutions.
Extending the loan term: lever or trap for your real estate project
The average duration of granted loans now significantly exceeds 20 years. Brokers note an almost systematic use of 25-year terms, or even the regulatory ceiling, to maintain monthly payments compatible with the 35% debt threshold imposed by the HCSF.
This lever comes with a cost that is rarely explained in consumer simulators. Moving from 20 to 25 years reduces the monthly payment but increases the total cost of interest to considerable proportions. The gain in monthly cash flow is paid over time, and the borrower repays capital more slowly during the first years.
When extending is justified
Extension remains relevant in two specific cases: a first-time buyer with a limited down payment whose income is documented as increasing (young executive, regulated profession), or a purchase in an area where the property’s appreciation statistically compensates for the additional interest cost.
On the other hand, extending to “make a project work” when the remaining disposable income is already tight after fixed charges exposes one to a risk of default in case of unforeseen events. We recommend simulating the project over 20 years first: if the debt ratio exceeds 35% at this duration, it is often the acquisition budget that needs to be reviewed, not the loan term.
Borrower insurance: an underutilized negotiation item
The cost of borrower insurance represents a significant portion of the total cost of credit, sometimes more than the bank’s own interest margin. The Lemoine law allows for changing insurance at any time, without fees or penalties, from the first day of the contract.
Delegated insurance can reduce the overall cost of credit more significantly than negotiating rates. On a long-term loan, the difference between the bank’s group contract and an external delegated offer regularly reaches several thousand euros.
- Compare guarantees at equivalent coverage levels (death, PTIA, ITT, IPT) before comparing rates: a cheaper contract that excludes IPT does not offer the same protection.
- Check the insured amount for each borrower in the case of a joint loan: 100%/100% coverage costs more but fully protects the surviving co-borrower.
- Anticipate the health questionnaire: some delegations offer very competitive rates for profiles without history, but apply significant surcharges as soon as an aggravated risk is declared.
Structuring the financing plan: down payment, subsidized loans, and multi-line setup
A financing plan is not limited to “down payment + amortizable loan.” The multi-line setup combining main loan, PTZ, and Action Logement loan optimizes the weighted average rate of the overall credit and can tip a borderline file.
The zero-interest loan remains reserved for first-time buyers under certain income conditions, but its base and ceilings evolve regularly. Checking eligibility at the time of file submission, not six months prior, avoids unpleasant surprises related to rate revisions.
Personal contribution: what threshold reassures the bank
Most institutions require a contribution covering at least the ancillary costs (notary fees, guarantee). A more substantial contribution improves the negotiation margin on the rate, but immobilizing all savings in the contribution leaves the borrower without a safety net.
- Maintain residual savings equivalent to several months of payments after the release of funds.
- Incorporate guarantee fees (mortgage or guarantee type Crédit Logement) into the financing plan from the start, as they add to the purchase price and notary fees.
- Do not overlook bank processing fees, which are sometimes negotiable, especially in the case of income domiciliation.
The debt ratio is calculated on net income before tax, including regular bonuses but weighted rental income. Banks generally apply a deduction on received rents to account for the risk of vacancy.
The rise in rates observed in the fall of 2026 requires finalizing the financial setup with wider safety margins than a year earlier. A well-structured file, with competitive delegated insurance and a calibrated contribution, remains the best lever to obtain favorable credit conditions in a context where every tenth of a point counts.
