An apartment rated G in the energy performance diagnosis, purchased with good yield on paper, can become a money pit if the rental ban is not anticipated. Between credit rates, energy regulations, and rental risks, the winning strategies of 2025 no longer resemble those from three years ago.
DPE constraints and renovation budget: the real filter before purchase
Since 2023, properties rated G in the energy performance diagnosis are gradually banned from being rented out. The F ratings will follow. This timeline, set by the Climate and Resilience Law, changes the way a real estate listing is interpreted.

When spotting a property listed with a discount, it is essential to check whether this discount truly compensates for the cost of energy renovation. A façade renovation with external insulation in a co-ownership, replacing a heating system, installing high-performance windows: these costs can add up quickly. Incorporating the renovation budget right from the profitability calculation helps avoid discovering after signing that the net yield falls below expectations.
This constraint can be turned into a lever. An F or G rated property purchased below market value, renovated to achieve a D or C rating, increases in asset value and rental attractiveness. The strategy works as long as the renovation costs are estimated before the purchase offer, not after. To delve deeper into the mechanisms of this type of setup, one can learn more about Conseil Invest, which details the trade-offs between yield and valuation.

Mortgage rates in 2025: balancing cash flow and capital gains
After the rate hike that began in 2022, a stabilization followed by a slight easing is observed at the beginning of 2025. This context changes the game for rental investment.
With rates lower than the peak of 2023, the monthly payment decreases and the monthly cash flow improves. Two options then emerge for the investor:
- Prioritize positive cash flow by targeting markets where rents comfortably cover the monthly payment, charges, and property tax, even if it means aiming for medium-sized cities with less potential for capital gains
- Bet on long-term capital gains by buying in tight areas where prices have corrected, accepting a monthly savings effort for a few years
- Combine both by purchasing a property to renovate in a developing area, allowing for a purchase discount while securing a reasonable rent after renovations
The choice between cash flow and capital gains depends on the intended holding period. Over five years, cash flow matters more. Over fifteen years, location and potential for revaluation take precedence.
Rental risk and unpaid rents: tenant selection as a management strategy
ANIL reports a significant increase in rental disputes and unpaid rents since 2023-2024, particularly in tight areas. The erosion of tenants’ purchasing power makes managing rental risk much more strategic than it was a few years ago.
This aspect is often underestimated. A single unpaid rent for six months can wipe out the profitability of an entire year. Tenant selection is not just about checking three pay slips. It is necessary to cross-reference the effort rate (rent/income ratio), professional stability, and the coherence of the application.
Guarantees to activate before signing the lease
Unpaid rent insurance (GLI) generally covers between 70,000 and 90,000 euros of unpaid rents, depending on the contracts. Its cost represents a few percentage points of the annual rent. For rental investment in a tight area, this cost is well justified given the risk.
The Visale guarantee, offered by Action Logement, is a free alternative for landlords. It covers unpaid rents and damages, but feedback on this point varies depending on the situations, and the scope of eligible tenants remains regulated.
In any case, not taking out a guarantee in the hope of saving money is like betting against the statistics. The cost of coverage is predictable, while the cost of an unpaid rent is not.
SCI or personal ownership: the legal structure that impacts net profitability
According to the Franchise Observatory and FNAIM, investment models through a company (SCI, SAS) have gained popularity in recent years. The choice of legal vehicle is not trivial: it determines taxation, asset transmission, and borrowing capacity.
In personal ownership, rental income is taxed at the progressive income tax scale. With a high marginal rate, the tax burden on rents can exceed half of the gross rental income. The SCI taxed under corporate tax (IS) allows for asset depreciation and reduces taxable income, but complicates resale (capital gains tax on net accounting value).
- SCI taxed under personal income tax (IR): tax transparency, ideal for family transmission, but rental income remains taxed at the personal rate
- SCI taxed under corporate tax (IS): depreciation of the asset, cash retained in the company, in exchange for heavier taxation upon resale
- Purchase in personal ownership with LMNP status: accounting depreciation of the property in furnished rental, often the most advantageous regime for a first rental investment
The LMNP status remains the most accessible structure to optimize the taxation of a first property, provided that revenue thresholds and accounting obligations are respected.
Each structure has its constraints. One does not choose an SCI simply because “it is better”; one chooses it because the project, the asset situation, and the holding horizon require it. A meeting with a specialized real estate accountant before signing the preliminary agreement costs a few hundred euros and helps avoid significant tax errors throughout the holding period.
