A T2 apartment purchased at a good price in a medium-sized city can generate a decent gross yield on paper, but can turn into a money pit if one neglects taxation or rental vacancy. The success of a rental property investment hinges on concrete decisions: the chosen tax regime, the type of lease signed, and the ability to keep a tenant in place. Maximizing your rental income requires more method than intuition.
Increased social contributions on furnished rentals: a parameter to consider starting in 2026
Since the income received in 2025, social contributions on non-professional furnished rentals (LMNP) have risen from 17.2% to 18.6%. Unfurnished rentals remain at 17.2%. This differential seems small in percentage terms, but it directly eats into the net profitability after tax of a furnished rental investment.
Specifically, for a landlord declaring their income in spring 2026, the social bill increases without the rents collected the previous year being adjusted. The net-net yield of furnished rentals mechanically declines, and one can no longer compare unfurnished and furnished rentals without factoring in this gap.
For those considering a first project, the simulations available on invistita.fr allow for a quick comparison of the two regimes before committing.
Jeanbrun scheme and rental depreciation: what changes in profitability calculation
The so-called “Jeanbrun” scheme, implemented in 2026, restructures the taxation of rental investments around depreciation. One can now depreciate up to 80% of the purchase price of the property, with annual rates varying according to the rental level practiced: between 3.5% and 5.5% for new properties, and between 3% and 4% for rehabilitated old ones.
The trade-off is far from trivial. Depreciations are reintegrated into the taxable capital gain upon resale. An investor who sells after ten years of depreciation at 4% per year ends up with a capital gain base significantly higher than that of an owner who did not depreciate.
This mechanism changes the game for wealth strategy. If the goal is to hold the property long-term (inheritance, retirement), depreciation remains advantageous since it postpones taxation. If one plans to sell in the medium term, the annual tax gain can be largely offset by the bill at exit.
New or rehabilitated old: the tax arbitration is no longer the same
With higher depreciation rates for new properties, the Jeanbrun scheme naturally steers towards recent construction. Rehabilitated old properties remain relevant when the price per square meter is significantly lower, which compensates for slower depreciation with a higher gross yield. Returns on this point vary according to local markets.
Rent control: tight zones and real ceilings
Rent control now affects several major French urban areas. In Paris, Lyon, or Grenoble, recent data shows that more than one in three listings exceed the authorized ceilings. For an investor, this means two things: the maximum rent is theoretically capped, but the real market still tolerates discrepancies.
Betting on exceeding the ceiling would be a management error. Tenants can contest the rent before the conciliation commission, and penalties are becoming stricter. The right approach is to:
- Check the applicable reference rent for the exact address of the property before any purchase, to incorporate this ceiling into the rental profitability calculation
- Prefer justifiable rent supplements (terrace, exceptional view, high-end equipment) rather than exceeding the ceiling without reason
- Anticipate the renewal of rent control experiments, some of which expire at the end of 2026, which could change the rules of the game in several cities
In non-regulated areas, rent remains free, but rental demand is often weaker. A free rent in a low-demand area does not guarantee a better yield than a controlled rent in a metropolis where rental vacancy is nearly zero.
Rental vacancy and lease management: concrete levers to protect your income
Rental vacancy is the primary destroyer of yield. One month without a tenant out of twelve means over 8% less income. Two months, and the net profitability of an average project falls below the threshold of the mortgage to be repaid.
To reduce this risk, one works on three concrete axes:
- Adapt the size and type of housing to the actual local demand (studios and T2s rent faster in university city centers, T3-T4s in family neighborhoods close to schools)
- Set a rent slightly below the market price rather than aiming for the maximum, which speeds up re-renting and reduces turnover
- Maintain the condition of the property between two tenants: a quick refresh (painting, joints, cleanliness) costs a few hundred euros but can prevent several weeks of vacancy
The choice of lease directly impacts taxation
Furnished or unfurnished, the tax regime depends on the type of lease signed. In furnished rentals, the real regime allows for the deduction of charges and depreciation of furniture. In unfurnished rentals, the micro-property regime simplifies the declaration but limits the deduction to a flat-rate allowance.
With the increase in social contributions on furnished rentals, some investors who systematically switched to LMNP should reconsider their calculations. The furnished option is no longer automatically the most advantageous for a property without significant work to depreciate.
Mortgage and rates: negotiate at the right time
The cost of credit weighs heavily on the profitability of a rental investment. Renegotiating your loan or borrower insurance after a few years can free up several dozen euros per month, which directly adds to the net cash flow.
A often overlooked point: the duration of the loan. Extending the loan reduces the monthly payment and improves immediate cash flow but increases the total cost. Shortening the loan does the opposite. The right arbitration depends on your wealth objective: positive monthly cash flow or rapid capital accumulation.
Profitable rental property investment in 2026 relies on rapidly changing tax parameters. Between the increase in social contributions on furnished rentals, the Jeanbrun scheme altering capital gain calculations, and the widespread rent control, every management decision has a direct impact on your net income. Calculating before buying remains the only reflex that sustainably protects a project.
