The average rate for home loans rose from 3.08% in December 2025 to 3.27% in June 2026, according to data from the Banque de France reported by Agence Étoile. This trajectory alters the parameters of any real estate project initiated today. Which cost items and financing levers deserve reevaluation to successfully carry out a purchase or rental investment in this context?
Mortgage Rates and Borrowing Capacity: Variables to Recalculate
A difference of a few tenths of a percentage point in the nominal rate significantly changes the total cost of a loan over twenty or twenty-five years. Relying on a single rate to simulate a project is no longer sufficient.
| Indicator | December 2025 | June 2026 |
|---|---|---|
| Average home loan rate | 3.08% | 3.27% |
| Share of rental investment in home loans | – | 12% (ACPR, 2025 data) |
The rise in the average rate necessitates testing multiple scenarios combining duration, personal contribution, and monthly payment. A project approved at 3.08% can become tight at 3.27% if the monthly payment approaches the debt threshold.
For rental investors, bank selection has tightened. The Prudential Control and Resolution Authority (ACPR), cited by Agence Étoile, indicates that the share of rental investment fell to 12% of home loans in 2025. Rental applications must demonstrate documented net returns and a comfortable remaining income to pass the filter.
Comparing offers from several institutions, including through a broker, remains the most direct lever to save a few basis points. Those who want to learn everything about ImmoGuru will find additional resources on market tracking and simulation tools.
EPC and Thermal Strainers: The Asset Risk Buyers Underestimate
The energy performance diagnosis is no longer just an administrative document. The phased exclusion schedule of the least efficient homes from the rental market transforms the EPC label into a top-tier financial criterion.
A rental purchase classified as F or G requires integrating three parameters before signing:
- The actual cost of energy renovation works, supported by quotes, not a flat-rate estimate per square meter.
- The regulatory schedule for rental prohibition, which can render the property unexploitable before the loan is fully repaid.
- The technical feasibility of the works in the concerned building (co-ownership, architectural constraints, access to networks).
A G-rated property purchased without a quantified renovation budget is a gamble, not an investment. The discount at purchase does not always compensate for the cost of bringing it up to standard, especially if public aid changes between signing and the start of the work.
Reform of EPC Calculation for Electric Homes
The revision of the EPC calculation method may change the label of certain homes heated with electricity without any work being done. Before purchasing a thermal strainer in hopes of automatic reclassification, check if the heating method of the property is affected by this reform. An EPC reclassification without work only concerns a fraction of homes.
Real Estate Budget 2024: Often Overlooked Items in the Financing Plan
Competitors extensively detail notary fees and personal contributions. Two less visible items weigh more heavily on the actual profitability of a project.
Borrower Insurance and Delegation
Borrower insurance can represent a significant portion of the total loan cost, sometimes as much as the interest in the early years. Comparing group contracts and insurance delegations before signing the loan remains the most effective way to reduce the overall bill. The law allows changing borrower insurance at any time, but in practice, few buyers exercise this right after signing.
Co-ownership Charges and Voted Works
An apartment whose price per square meter seems attractive may hide upcoming funding calls. Consulting the last three general assembly minutes allows spotting voted or discussed works. A facade renovation, roof repair, or elevator compliance can add several thousand euros to the actual acquisition budget.
Financing Scenarios: Why Simulating Multiple Durations Changes the Decision
The temptation is to extend the duration to reduce the monthly payment. In a context of rising rates, this strategy often has an underestimated cost.
Extending a loan from twenty to twenty-five years reduces the monthly payment but disproportionately increases the total interest cost when the rate exceeds 3%. Conversely, shortening the duration assumes sufficient remaining income to absorb an unexpected event (job loss, urgent repairs).
The right scenario is neither the shortest nor the longest, but the one that leaves a monthly safety margin. Testing at least three combinations (short duration with high contribution, medium duration with moderate contribution, long duration with minimal contribution) provides a realistic view of the financial commitment.
For a rental investment, the simulation must also include periods of vacancy and the differential between rent received and loan monthly payment. A project that appears profitable on paper can become unprofitable if the property remains empty for two months a year.
The rise in rates to 3.27% in June 2026 reminds us that financing is just one variable among others. The EPC, hidden charges, and duration scenario weigh as heavily on the success of a real estate project as the purchase price itself.
