Is it profitable to buy an apartment to rent it out?

The 2026 real estate market marks the end of the wait-and-see attitude. After years of turmoil, the indicators are stabilizing. Credit rates hover around 3%, offering investors unprecedented visibility.

But be careful: gross profitability is no longer enough. In 2026, the performance of an asset is judged by its fiscal resilience and its rental pressure. This guide deciphers the winning strategies to turn your walls into a cash machine.

1. Understanding the real estate market in 2026

The landscape has changed. We are no longer in the era of free money, but in the age of careful selection. Prices have ended up adjusting in most cities, creating shooting windows for those who know how to bargain.

‍

The state of interest rates and purchasing power

In February 2026, the average rate was 2.90% over 20 years. It is a balance point. Banks have built up their margins and are lending again, but they require flawless records.

Personal input remains the lifeblood. It makes it possible to compensate for the erosion of real estate purchasing power. To follow the precise evolution of these financing conditions, consult the analyses of Best rate, the reference for brokerage in France.

As a hunter, I see customers who now prioritize the quality of the location over the surface to secure their financing.

‍

Rising rents and rental pressure

The housing shortage has not been resolved. On the contrary, rental tension is exploding in medium-sized cities. Rents increased by 1.3% on the national average over one year.

In cities like Toulouse or Marseille, demand is such that the risk of a rental vacancy becomes almost zero for well-renovated properties.

It is this lever that maintains net profitability at attractive levels despite purchase prices that are rising slightly (+1.6% at the national level).

‍

The impact of the DPE on the value of goods

In 2026, the green value is no longer a bonus, it is a prerequisite. Thermal sieves (G and F) are undergoing massive discounts.

For an informed investor, it is an opportunity to buy below the market price. The calculation is simple: buy a colander, renovate with the state aid still available, and reposition the property on the market with premium rent. The final profitability on these operations often exceeds 6% net.

2. Top of the most profitable cities in 2026

Forget Paris for pure performance. In 2026, “cash flow” is being sought in the provinces and in the periphery belts of major cities.

‍

The nuggets of high gross profitability

If you are looking for 8% to 10% gross, turn to cities that have been able to boost their employment pool.

• Saint-Étienne : Still queen of performance with studios nearing 10%. The price per m² remains unbeatable at around €1260.
• Mulhouse: A serious outsider who shows record gross returns sometimes exceeding 13% in certain emerging neighborhoods.
• mans : Boosted by its TGV connection with Paris, the city offers an ideal compromise with 7.3% average return and a very low rental vacancy.

‍

Cities with the best risk/return ratio

For a heritage investment that also generates cash, some big cities stand out.

• Marseilles: The 3rd arrondissement remains a gold mine with returns of 11.9% gross, although the management risk is higher.
• Amiens: It is the city of balance in 2026. Moderate prices (2400€/m²), high student population and stable return of around 7%.
• toulon : Rental pressure jumped by 38% there. It is the city where the rents catch up the most quickly with the price of the acquisition.

‍

The emergence of medium-sized “satellite” cities

Teleworking has established a sustainable trend: cities 1 hour away from Paris or Lyon are a hit.

• Nevers and Chalon-sur-Saône: Yields between 7% and 9% for very low entry prices. Ideal to start without going overindebted.
• Montauban: It takes full advantage of the Toulouse satellite effect. There are new LMNP studios with secured returns of 5.5%.

3. Taxation 2026: Navigating between LMNP and property income

Taxation underwent a serious facelift in early 2026. If you don't update your strategy, the state will become your main partner.

‍

The reform of the LMNP and furnished tourist accommodation

Short-term rentals fell on the downturn. For unclassified furnished tourist accommodation, the micro-BIC ceiling has been lowered to €15,000 with a reduction reduced to 30%.

This is a clear signal: the State favors long-term rentals. You can find the official details of these thresholds on Service-public.fr, the official website of the French administration.

Fortunately, for classic furnished rentals (students, mobility leases), the 50% discount up to €77,700 is maintained. The LMNP status remains the most powerful tool for cancelling taxes thanks to real accounting depreciation.

‍

The rise in social security contributions

Bad news for cash flow: the CSG has increased. The overall rate of social security contributions on wealth income now reached 18.6% (compared to 17.2% previously).

This increase of 1.4 points has a direct impact on your net profitability after taxes. It is more crucial than ever to switch to the real regime to deduct each euro of loan charge and interest in order to reduce the tax base.

‍

Why did the real regime become mandatory

In 2026, staying on the micro regime (lump-sum deduction) is often a beginner's mistake. With the increase in property taxes and energy renovation costs, your real expenses almost always exceed the 30% or 50% lump-sum allowance. The real regime allows you to deduct:

1. Loan interest.
2. Energy renovation work (double impact: value of the property + tax reduction).
3. The amortization of walls and furniture. This is the only way to maintain a net-net return greater than 4% in tense areas.

Conclusion: What strategy should we adopt in 2026?

Rental investment in 2026 can no longer be improvised. The profitability is there, but it has to be earned. The key to success lies in three pillars: a aggressive negotiation based on the DPE, a Medium-sized city choice with high rental tension, and a Tax optimization under the real regime. The market is healthy, rates are stable, and housing demand is historic. It is time to act for those who aim for the long term.
