A couple in their thirties with two permanent contracts, a decent down payment, and clean accounts finds themselves denied a mortgage because the proposed rate exceeds the usury rate by a few hundredths. This scenario, common until recently, is changing. Legal ceilings have risen in 2026, the zero-interest loan has been expanded, and banks are once again looking for applications. Let’s take stock of the concrete levers to secure real estate financing under favorable conditions.
Usury Rate in 2026: The Lock That Is Being Released for Borderline Applications
The usury rate is the ceiling beyond which a bank is not allowed to lend. For several years, this ceiling was so low that it mechanically blocked solvent borrowers. Their nominal rate, added to borrower insurance and processing fees, exceeded the legal limit.
In 2026, the usury ceilings have significantly increased for long-term loans. Specifically, applications that would have been denied two years ago now fall below the threshold. For senior profiles or borrowers with more expensive insurance, this is a direct change in the feasibility of the project.
You can access Aujourd’hui J’investis credit to compare financing offers and quickly identify banks whose conditions remain below this ceiling.
What to remember: check the overall APR before signing, not just the nominal rate. The APR includes insurance, guarantee fees, and processing fees. It is this that is compared to the usury rate.
Expanded PTZ: What the March 2025 Decree Changes for Financing
The zero-interest loan has been thoroughly revised by decree no. 2025-299 of March 29, 2025. Two major changes directly affect the financing strategy for a property purchase.
PTZ for New Properties: Opening Up to the Entire Territory
The PTZ now covers the entire territory for new housing, without any zoning restrictions. This is a significant expansion compared to the previous framework. For first-time buyers aiming for construction or a purchase in VEFA, the PTZ complements the main mortgage and reduces the total amount of interest.
PTZ for Existing Properties: Stricter Conditions Than They Appear
For existing properties, the PTZ remains limited to zones B2 and C. Two additional constraints apply:
- Renovation work must represent at least 25% of the total cost of the operation, which excludes properties requiring little renovation
- The property must achieve at least a class D in the energy performance diagnosis after renovations, which often requires complete insulation or a change of heating system
These requirements change the budget calculation. A cheap old property rated F will require a significant amount of renovation work to be eligible for the zero-interest loan. It is recommended to accurately estimate the cost of energy renovation even before visiting.
The scheme is extended until December 31, 2027. This multi-year visibility allows for planning a real estate project without fearing the removal of the PTZ along the way.
Preparing the Mortgage Application: The Decisions That Really Matter
Competitors detail the management of accounts and personal contributions extensively. We won’t go back to that. However, three technical decisions can shift an application from “average” to “financed under good conditions.”
Loan Duration and Actual Cost of Credit
Extending the repayment period reduces the monthly payment but increases the total cost of interest. The real calculation is to compare the additional interest cost with the gain in borrowing capacity. Moving from 20 to 25 years can help stay below the 35% debt threshold without touching the down payment.
Opinions vary on this point: some bank advisors prefer short durations to limit risk, while others readily accept 25 years if the rest of the application is solid.
Borrower Insurance: The Item That Is Poorly Negotiated
Borrower insurance can represent a third of the total cost of credit over 25 years. Since the Lemoine law, one can change borrower insurance at any time. Comparing delegation insurance offers with the bank’s group contract often lowers the APR by several tenths of a point.
Personal Contribution: How Much to Put on the Table
Banks generally require that the contribution covers at least the notary and guarantee fees. Going beyond that improves the proposed rate conditions, but depleting one’s emergency savings is counterproductive. A borrower without a safety net worries the lender just as much as a borrower without a contribution.
- Covering ancillary costs (notary, guarantee, processing fees) with the contribution is the minimum expected
- Keeping the equivalent of three to six months of current expenses in residual savings reassures the bank about income management
- Injecting a higher contribution allows for negotiating a discount on the nominal rate, especially beyond 20% of the borrowed amount
Negotiating with Banks: What Makes a Difference on the Rate
Presenting your application to a single bank means accepting its conditions without a point of comparison. Contacting three to five institutions remains the most effective lever to obtain a competitive rate. Banks adjust their offers when they know a competitor is in the running.
Timing also matters. Banks operate with quarterly commercial objectives. At the beginning of the year or at the end of the quarter, some offer more aggressive conditions to meet their credit production quotas.
A broker can accelerate this competition, but their intervention is not always necessary. For a simple application (permanent contract, stable income, decent contribution), directly approaching online banks and local agencies yields comparable results.
Financing a property purchase in 2026 benefits from a more favorable context than two years ago: increased usury rates, an extended PTZ, and banks lending again. The work remains on the borrower’s side, in preparing the application and negotiating. Every tenth of a point saved on the rate translates into several thousand euros saved over the total duration of the loan.
