Rental investment now accounts for only 12% of new real estate financing in 2025, down from 14.9% a year earlier according to data reported by Ouest-France. This contraction in the market does not mean that the operation has become less relevant, but it imposes increased rigor at every stage of the project. Interest rates, tax reforms for LMNP, and the lengthening of tenant stay durations are reshaping the parameters of a profitable real estate investment.
Tenant Stay Duration: An Underestimated Parameter in Profitability Calculation
Most rental investment guides reason on an annual cycle: monthly rent, charges, and estimated vacancy of one month per year. This approach ignores a fundamental trend documented by Maslow.immo over nearly 30,000 leases closed between 2019 and 2025: the average stay duration has increased from 28.3 months to 37.6 months, representing an increase of about one third.
A tenant who stays three years instead of two means reduced turnover, lower refurbishment costs between leases, and a drop in vacancy rates. However, this also means that the rent remains fixed for a longer period, indexed only to the IRL, without the possibility of reevaluation at market price with each tenant change.

The choice of lease type (furnished or unfurnished, mobility or classic) takes on a new dimension when the average tenant stays more than three years.
LMNP Reform 2026: What Changes with the Reintegration of Depreciations
The status of non-professional furnished landlord has long been a major tax lever. The ability to depreciate the property while deducting expenses allowed for a reduction or even elimination of taxation on rental income for several years.
The reform that has come into effect modifies this mechanism. Depreciations deducted are now reintegrated into the calculation of the capital gain upon resale. Specifically, an investor who has depreciated 80,000 euros over ten years will see this amount added to their taxable capital gain when selling the property.
This evolution does not eliminate the interest of LMNP during the holding phase. Rental income remains lightly taxed thanks to depreciations. The change affects the exit: selling an LMNP property after several years of depreciation is now more costly from a tax perspective than before.
Balancing Long-Term Holding and Resale
The allowance for holding duration continues to apply to real estate capital gains. An investor who retains their property for more than twenty-two years benefits from a total exemption from income tax on the capital gain (thirty years for social contributions). The question thus becomes: does the net profitability during the holding period compensate for the additional tax cost at resale if it occurs before these thresholds?
Field returns diverge on this point. Some investors believe that LMNP remains attractive for high rental yield properties (small units in tight areas, shared accommodations). Others are redirecting their strategy towards unfurnished rentals with a property deficit, which allows for the deduction of renovation costs from overall income.
Real Estate Credit and Rates: Balancing Gross Yield and Real Financing Costs
The gross yield of a rental property says very little about its actual profitability. An apartment advertised at a 7% gross yield in a medium-sized city can drop below 3% net after accounting for the cost of credit, property tax, condominium charges, and taxation.
- The mortgage rate determines the total cost of the operation over fifteen or twenty years. A half-point difference in the rate can represent several thousand euros over the duration of the loan.
- Property tax varies significantly from one municipality to another. Some municipalities have made significant increases in recent years, directly eating into net yield.
- Condominium charges in older buildings can absorb a significant portion of rents, especially in buildings requiring energy renovation work.
- Borrower insurance, often overlooked in quick simulations, represents an expense that can be optimized through delegation.
Calculating net profitability after tax and actual charges remains the only reliable method for comparing two purchase opportunities. Online simulators that stop at gross yield often lead to errors.
Tight Rental Market and Vacancy Rates: Choosing Location Based on Data
The shortage of rental housing in many French metropolitan areas creates a favorable context for landlord owners. Areas where rental demand far exceeds supply allow for maintaining occupancy rates close to 100% and selecting strong tenant profiles.
Analyzing a location based on data means going beyond a neighborhood’s reputation. The vacancy rate, demographic trends, and the volume of new constructions are three indicators that allow for assessing the real rental tension of a sector.
New or Old: A Choice Dependent on the Local Market
The construction of new housing remains behind the estimated needs in several regions. This structural deficit supports prices in the old market and maintains high rental pressure. For an investor, buying in the old market with renovations can offer a better entry yield, provided they manage the renovation budget and comply with new energy performance requirements (DPE).
New properties, on the other hand, offer reduced notary fees and no work for several years, but at a generally higher purchase price per square meter. The choice between new and old is determined by the projected net yield over ten years, not by a principle-based preference.
Real estate rental investment in 2026 is guided by more granular data than five years ago. The tenant stay duration, the tax implications of LMNP after reform, and the real cost of financing form a triptych that every project must integrate from the study phase. Neglecting any of these parameters means building a profitability projection on incomplete foundations.
