An apartment listed at a good price in a vibrant city, a loan approved quickly, and six months later the rent doesn’t even cover the monthly payment. This scenario is often encountered by investors who have overlooked two or three checks before signing. Successfully investing in real estate relies less on intuition and more on a method: analyzing exit taxation, checking the energy performance diagnosis (DPE), and calculating a realistic net yield.
Taxation of LMNP upon resale: the trap that few buyers anticipate
Since February 15, 2025, the depreciation deducted under the real regime of non-professional furnished rental is reintegrated into the calculation of capital gains upon resale. In simple terms, the tax savings made each year during the property’s operation inflate the taxable base at the time of selling the property.
Before this date, one could depreciate the property and sell it without these depreciations having a direct tax impact. The exit taxation radically changes the profitability calculation of a furnished property. An investment that seemed profitable over ten years can lose a significant part of its net advantage once the capital gain is recalculated.
When studying real estate investment with Capitaine Immo, this data is part of the parameters to be integrated from the initial simulation. A furnished project remains relevant in certain configurations, but one must model the resale scenario, not just the annual rental income.
Some serviced residences escape this reintegration. If the project targets a student or senior residence under a commercial lease, the rule may differ. Checking the specific case before committing avoids an unpleasant tax surprise upon exit.

DPE and rental ban schedule: balancing the purchase price
Properties classified as G can no longer be offered for rent since January 1, 2025. Class F properties will be affected in 2028, followed by class E properties in 2034. This schedule creates mechanical pressure on the prices of energy-inefficient properties, but also a window of opportunity for those who can estimate renovation costs.
Buying a property classified as F or G is only profitable if the cost of energy renovation is factored into the price negotiation. We still see buyers paying the market price for an F, only to discover that insulation and heating changes absorb all the rental margin of the first five years.
The electrical coefficient changing in 2027
A decree published in August 2026 plans to reduce the electricity conversion coefficient to primary energy from 1.9 to 1.7 starting January 1, 2027. In practical terms, some properties heated by electricity could improve their DPE label without any work.
For an investor, this means that a property classified as F with electric heating could shift to E after recalculation. Buying this type of property before the reform, at a negotiated price as an energy sieve, and then benefiting from automatic reclassification represents a concrete profitability lever. Returns vary on this point depending on the exact configuration of the property, but the principle deserves to be systematically explored.
Net rental yield: what the gross calculation does not show
The gross yield (annual rent divided by purchase price) gives a rough idea, nothing more. A property listed at 7% gross can fall below 3% net after accounting for all actual expenses.
Here are the often underestimated items in a yield calculation:
- Property tax, which varies significantly from one municipality to another and has increased in many cities in recent years
- Rental vacancy: even in a tight area, planning for at least one month of vacancy per year remains prudent
- Non-recoverable charges, particularly major co-ownership works voted in general assembly
- Non-occupant owner insurance and unpaid rent guarantee, each representing a few percent of the annual rent
A net yield of 4% after all these items is already a solid performance in most French markets. Aiming higher is possible, but generally requires accepting a higher rental risk or a less central location.

Debt ratio and real estate credit strategy
The rule from the High Council for Financial Stability limits the effort rate to 35% of income, all loans combined. Ludovic Huzieux, managing director of Artémis brokerage, indicates that the share of investors in mortgage loan applications has dropped to 8% in the early months of 2026, down from about 20% a few years ago.
This tightening pushes for optimizing the financing structure. For a loan of 200,000 euros, the monthly payment is now around 1,200 euros, compared to 900 euros five years ago. The financial setup determines feasibility even before choosing the property.
Prioritizing cash flow or capitalization
Two approaches coexist. Lengthening the loan term reduces the monthly payment and preserves monthly cash flow, allowing room to absorb an unexpected expense or prepare for a second purchase. Shortening the term increases the cost of credit but accelerates the accumulation of net wealth.
One cannot decide in absolute terms: an investor with stable income and low existing debt should increase leverage over a long term. A profile close to the 35% ceiling, on the other hand, must secure each monthly payment.
The old property market has recently rebounded while new housing continues to decline. This dynamic naturally directs investors toward existing properties, often cheaper per square meter and quicker to rent out. The trade-off is the DPE risk and the renovation budget, which we have already discussed. Each profitable real estate investment project is built on this balance between entry price, compliance costs, and realistic local market rent.
