A rental real estate investment is defined by the acquisition of a property intended to generate regular income in the form of rents, while also building wealth over the long term. In 2024, financing conditions and the regulatory framework have significantly evolved, which alters the profitability calculation of an operation compared to previous years.
Rental mortgage: conditions to recalculate in 2026
The recovery of housing credit observed in 2025 masks an imbalance. According to the ACPR, the share of rental investment in new loans has fallen to 12%, three points lower in a year. The financing dynamics are benefiting home ownership more than rental investments.
The average rate of new housing loans stopped decreasing in mid-2025, reaching 3.08% in December 2025 before rising slightly at the beginning of 2026. For a rental project, this means that a financing plan based on rates at the end of 2024 may prove to be overly optimistic.
Testing the profitability of your purchase with several interest rate scenarios (steady, moderate increase, significant increase) helps avoid a squeeze effect between the cost of credit and the rents received.

EPC and rental ban: the timeline affecting profitability
The energy performance diagnosis is no longer just an administrative document. It now conditions the right to rent out a property. Properties classified as G are already subject to the ban, and properties classified as F will follow according to the regulatory timeline.
A often underestimated point: the EPC risk is not limited to the initial rental of a newly acquired property. It also concerns existing leases upon their renewal or extension. A landlord whose property falls below the energy decency threshold may lose the rental continuity of the property, which directly affects its resale value.
Mainland and overseas: two distinct timelines
The EPC timeline is not the same in mainland France and in overseas territories. In Guadeloupe, Martinique, Guyana, Réunion, and Mayotte, the deadlines differ. An investor diversifying their portfolio between mainland and overseas must check the specific dates applicable to each territory.
Before any purchase, the budget for energy renovation work must be included in the overall financing plan, and not treated as an optional expense after acquisition.
Rental yield: what the gross rate does not reveal
The gross yield (annual rent divided by purchase price) provides an initial selection filter, but it is not enough to assess the relevance of a project. Several factors reduce the actual profitability:
- Non-recoverable co-ownership charges, property tax, and non-occupying owner insurance, which vary greatly from one municipality to another
- The cost of delegated property management (agency fees, ongoing management fees, unpaid rent guarantee), which represents a significant portion of the rents received
- Rental vacancy, meaning periods without a tenant between two leases, the duration of which depends on the tension in the local market
- Routine maintenance work and compliance updates, particularly those related to the EPC
The net yield after charges and taxation is the only reliable indicator for comparing two projects against each other. A property listed at an attractive price in a city with low rental demand may generate a lower net yield than a more expensive property located in a tight market.
Rental taxation: choosing the right regime before buying
The tax regime applicable to rental income depends on the type of rental (unfurnished or furnished) and the amount of rent received. This choice has a direct impact on the net income generated by the operation.
Unfurnished and furnished rentals
In unfurnished rentals, rental income is subject to the progressive income tax scale. The micro-property regime (flat-rate deduction) applies below a certain threshold of annual rents, while the real regime allows for the deduction of actual charges and loan interest.
In furnished rentals, the LMNP status allows for accounting depreciation of the property, which reduces the taxable base. A reform of the furnished rental regime is expected, and the conditions may evolve. Any furnished rental project launched today must incorporate this regulatory risk.
Simulate before signing
Comparing the net result after tax between unfurnished rental under the real regime and furnished rental under the LMNP regime, over the intended holding period, is part of the steps to be taken before signing the preliminary agreement. A difference in tax regime can reverse the profitability of the same property.
Property location: the criterion that conditions everything else
The rental tension of a city determines both the applicable rent level, the duration of vacancy between two tenants, and the potential for capital gain upon resale. A quality location in a dynamic city often compensates for a higher purchase price per square meter.
Three concrete elements to check before committing:
- The proximity to transport, shops, and services (schools, healthcare), which conditions rental demand
- Current or planned urban development projects (new transport line, neighborhood renovation), which may affect the property’s value
- The average rental vacancy rate in the area, available from local housing observatories
A poorly located property in an attractive city remains a bad investment. The precise location (neighborhood, street, floor) is as important as the city itself.
The rental investment market in 2024 requires cross-referencing financing, EPC constraints, taxation, and location in a single calculation. Profitable operations exist, but they require prior numerical analysis, not a decision based solely on the purchase price or the promise of a gross yield.
