Gross rental yield is no longer enough to assess a property investment. Since 2025, regulatory constraints on energy performance ratings (DPE), tax reforms affecting LMNP status and tighter credit conditions have reshaped investment decisions. Building lasting wealth through property means understanding these factors before even choosing a property.
DPE ratings and rental bans: the regulatory check before any purchase
Properties rated G have been excluded from new leases since January 1, 2025. Class F properties will follow in 2028, and class E properties in 2034. A property advertised with a high gross yield but rated F or G may require an energy-efficiency renovation budget that could absorb several years’ worth of rent.
The electricity conversion factor used to calculate the DPE rating was lowered to 1.9 in 2026, with a further reduction to 1.7 planned for January 1, 2027. For electrically heated homes, this revision may shift the rating by one class. ADEME offers an official certificate for affected properties: rely on the updated assessment, not a personal estimate.
Before making any rental property purchase, we recommend checking the property’s actual DPE rating and estimating the cost of bringing it into compliance. A property investment that looks profitable on paper can become loss-making if the property is banned from the rental market before the loan is paid off.

LMNP tax treatment on resale: a rule change that reshapes the entire strategy
Until now, the non-professional furnished rental (LMNP) status under the actual-expenses regime allowed landlords to deduct depreciation from rental income without affecting the capital gain on resale. This was one of the most powerful tax advantages of investing in furnished rental property.
Since February 15, 2025, deducted depreciation has been added back when calculating taxable capital gains, subject to certain exceptions. The impact is direct: an investor who has depreciated a property for ten years and then sells it will see their taxable basis increased by the total depreciation claimed.
This change means that the return on a furnished rental investment must be assessed over the entire holding period:
- Net rental income after expenses and annual taxes, which remains tax-advantaged under the actual-expenses regime while the property is rented out
- Net capital gain on resale, now increased by the depreciation added back, reducing the actual profit on exit
- An appropriate holding period, since capital gains tax allowances based on the length of ownership may partially offset this adjustment after a certain number of years
A property held long enough benefits from progressive allowances that soften the impact of adding back depreciation. The LMNP actual-expenses strategy remains worthwhile, but quick resales are no longer advisable.
Property financing and leverage: balancing interest rates, loan term and cash flow
Leverage through borrowing remains property’s main structural advantage over financial investments. Borrowing to invest lets you control an asset worth far more than your initial contribution. Returns are therefore calculated on the equity invested, not on the property’s total price.
The debt-to-income ratio cap of 35% of income limits borrowing capacity. Two adjustments remain available: extend the loan term to reduce monthly payments, or increase the down payment to borrow less. Each option affects the return on equity in the opposite way.
Extending the loan term increases the total cost of borrowing but preserves monthly cash flow. Increasing the down payment reduces borrowing costs but lowers leverage. Positive cash flow from the first year helps protect the investment against unexpected costs (vacancy, repairs, rising expenses).
Run the numbers before signing
A rental yield spreadsheet that factors in actual taxes (the micro or actual-expenses regime, social contributions and property tax) gives a more reliable picture than the gross yield shown in a listing. Property management, whether outsourced or handled directly, is another cost to include in the calculation.
Diversifying your property portfolio: don’t put everything into one property
Concentrating your entire portfolio in a single rental apartment exposes you to the risk of vacancy, damage or a decline in local property values. Diversification can take several forms without adding too much management complexity.
- Vary property types: a city-centre studio and a three-bedroom apartment on the outskirts are subject to different rental demand cycles
- Combine unfurnished and furnished rentals: their tax regimes differ, allowing you to optimize the overall tax burden on rental income
- Add property funds (SCPI, OPCI) to gain exposure to commercial or logistics real estate without direct management, with a lower entry cost
Geographic diversification reduces exposure to local risks (an employer closing down, an unfavorable market shift). Investing in two dynamic mid-sized cities rather than two properties on the same street radically changes the portfolio’s risk profile.
A lasting property portfolio is built on decisions made in line with current tax and regulatory rules, not those in place five years ago. The return on a rental investment should be assessed over the full cycle: purchase, operation and resale. Every stage matters.
