A real estate rental project often hinges on contractual and regulatory details that advertising portals do not highlight. Since October 1, 2026, new lease models incorporate clauses and mentions that change the way a file is prepared, whether one is a landlord or a tenant. Understanding these developments allows one to gauge what separates a well-framed project from a fragile rental investment.
New residential leases since October 2026: what the models require
The regulatory models applicable to unfurnished, furnished, and single lease co-rentals have been updated for leases concluded or renewed from October 1, 2026. Several additions deserve careful reading before any signature.
The termination clause for unpaid rent is now systematically integrated. The period after an unsuccessful payment order is set at six weeks, which shortens the sequence between the first incident and the potential termination of the lease.
The new models also include mentions related to the possible obligation of primary residence, the energy class of the housing, and the estimation of annual energy costs. In practical terms, a tenant has a projection of their energy bill from the moment they read the lease, and a landlord must ensure that this information is clearly stated.
To structure a rental project considering these requirements, going through real estate rental with Immorise allows access to properties whose leases already comply with the current regulatory framework.
| Lease Element | Before October 2026 | Since October 2026 |
|---|---|---|
| Termination clause for unpaid rent | Optional (often included) | Integrated into the regulatory model |
| Period after payment order | Variable depending on contracts | Six weeks |
| Mention of energy class | Annexed via the DPE | Included in the body of the lease |
| Estimation of annual energy costs | Not required in the lease | Mandatory in the model |
| Mention of primary residence | Sometimes absent | Provided for by the new models |
Timeline for banning energy-intensive housing and rental profitability
The timeline for banning rentals related to energy performance structures all medium-term rental investment strategies. Properties classified as G can no longer be offered for rent since January 1, 2025. Class F will follow in 2028, and class E in 2034.
A property advertised with an attractive rental yield but classified as F or E therefore implies a budget for energy renovation to be included from the initial calculation. Without this anticipation, the project may become unviable by the regulatory deadline.
Renovation items and available aids
MaPrimeRénov’ is accessible to landlord owners to finance part of the energy renovation work on a property being rented. The amount depends on the type of work and the owner’s income, but the existence of this scheme modifies the calculation of net profitability.
- Thermal insulation (walls, roof, floors): the most expensive item, but one that can shift the energy class up one or two levels
- Replacement of the heating system: switching from an old oil or gas boiler to a heat pump or hybrid system
- Controlled mechanical ventilation: often overlooked, it conditions the validity of the DPE by limiting losses
A landlord acquiring a property classified as F in 2026 has less than two years before the rental ban. The renovation budget must be included in the initial financing plan, not as an option.
Taxation of furnished rentals: current regime and points of caution
Today, the LMNP status allows for the depreciation of the property from rental income, significantly reducing the taxable base. If this deduction were to be removed or capped, the net profitability gap between unfurnished and furnished rentals would narrow.
Unfurnished or furnished rental: the variables to compare
The choice between these two regimes does not rest solely on taxation. The lease duration differs (three years minimum for unfurnished, one year for furnished, nine months for a student lease), which changes rental management and tenant turnover.
- In unfurnished rentals, property income is taxed at the progressive rate or under the micro-property regime with a flat-rate allowance
- In furnished rentals, income falls under industrial and commercial profits (BIC), with a micro-BIC or real regime allowing for depreciation
- The mandatory furniture in furnished rentals (bedding, cooking plates, refrigerator, table, lighting) represents an additional initial investment and a periodic renewal item
The question is not which regime “brings in more” in absolute terms. The choice depends on the landlord’s tax profile and the intended holding period.
Rental management: delegate or manage yourself
Rental management regularly consumes time: searching for tenants, drafting leases, conducting inventories, collecting rents, managing claims, tax declarations. Delegating to a property manager generally costs between five and ten percent of the rents collected, including charges.
On the other hand, managing oneself allows for retaining all rents and maintaining direct contact with the tenant. This option remains viable for one or two properties located near the owner’s home. Beyond that, the time spent on ongoing management reduces the actual profitability of the project.
The relevant calculation is to relate the cost of delegation to the number of hours saved per month. For a property generating modest rents, the net difference between direct management and delegated management may only represent a few dozen euros monthly.
The success of a real estate rental project relies less on location or gross yield than on mastering the contractual and tax framework in which it operates. The new lease of October 2026, the energy timeline, and possible changes to the LMNP status form three constraints that, taken together, redefine the actual profitability threshold of a rental investment.
