The profitability of a rental investment depends less on a real estate "deal" than on a coherent local market: a sufficiently low purchase price, rents capable of keeping pace, and demand steady enough to avoid months of vacancy. In France, this trio explains why some so-called "secondary" cities show gross yields significantly higher than those of the most expensive metropolises, while remaining accessible with a reasonable budget. The most profitable cities are therefore not necessarily the best known: they are often those where the price per square meter remains contained, where renting happens quickly, and where the student or salaried population creates a pool of tenants.
The most profitable cities for rental investment
The city of Saint-Étienne and its high yields
Saint-Étienne has become a classic in investor discussions, and it is no coincidence: profitability there is first and foremost “mathematical”. As of March 1, 2026, MeilleursAgents estimates the average price of apartments at €1,245/m² (with a stated range of €891 to €1,922/m² depending on the sector). The entry ticket is therefore much lower than in many French cities, which makes it possible to aim for a high gross profitability even with moderate rent.
On the rental side, SeLoger shows levels in Saint-Étienne (January 2026 data) that remain sufficiently promising: for example, a 1-bedroom apartment (2 pièces) is estimated at around €10.8/m² furnished and €9.0/m² unfurnished. In concrete terms, if you buy a 40 m² 1-bedroom apartment for around €55,000 to €65,000 (an order of magnitude consistent with a price per m² close to the average), a monthly rent of €360 to €430 unfurnished is not unrealistic, and the gross yield can easily exceed the 7–8% mark… even before talking about optimization (furnished, shared housing, renovation).
What changes the game in Saint-Étienne is that rental demand does not rely solely on the “bargain effect”. The city assumes a university profile: the municipality mentions nearly 30,000 students (page updated in October 2025). This student base favors small areas, housing close to transport, and sectors where the offer is clear (center, commercial axes, well-connected neighborhoods). In other words: high yield is not just a figure on Excel, it can rely on real demand, provided you do not target micro-markets where vacancy rates climb quickly.
The city of Mulhouse and its very low real estate prices
Mulhouse is one of those cities where the gap between purchase price and rent remains surprisingly favorable. As of March 1, 2026, MeilleursAgents indicates an average apartment price of €1,162/m². For an investor, this means that a studio or a 1-bedroom apartment can still be financed at levels that leave room on the rent, even after integrating charges, property tax, and a maintenance budget.
On rents, SeLoger gives for Mulhouse (January 2026 data) an average price of around €13/m² (with a variation of €9 to €20/m² depending on location and typology). The combination of “low purchase / decent rent” is precisely what ranks Mulhouse among the most profitable cities for a rental investment: a property bought for €70,000 and rented for €520–€600 per month (depending on size and location) can quickly show a solid gross yield.
One must also look at the structure of demand: Mulhouse benefits from a particular geographical situation, between a local employment pool and cross-border flows, and a university hub. Even if the figures vary according to the perimeter chosen, the existence of a structured higher education offer is a positive signal: it favors small surface area rentals, mobility, and a certain rental rotation (which can be an advantage if the property is well managed). And this is where one must remain lucid: Mulhouse rewards the investor who chooses a “rental” location rather than a “personal favorite” location. Low prices exist everywhere, but rental liquidity is not uniform.
The city of Limoges and its price-rent balance
Limoges does not play exactly the same match as Saint-Étienne or Mulhouse: the city stands out more for its balance. MeilleursAgents estimates the average price of apartments at €1,549/m² as of March 1, 2026 (range €973 to €2,224/m² depending on the address). This is higher than in Saint-Étienne, but it remains a market where buying is still accessible, with rental demand less “tense” than in large metropolises, but often clearer than in some very cheap cities.
On rents, SeLoger indicates in Limoges (January 2026 data) an average price around €11/m² in several neighborhoods, with a reported range of €7 to €18/m². The interest is clear: a 1-bedroom apartment bought at a reasonable price and rented at a consistent level makes it possible to aim for a gross profitability often located around 6–7%, sometimes more if you secure a good purchase price or if you opt for a well-calibrated furnished rental.
Limoges also benefits from a “student” engine that supports demand for studios and small apartments. The city of Limoges, in its page dedicated to student life, recalls that the University of Limoges has more than 17,000 students. This figure is not anecdotal: it helps stabilize the rental market, especially around study hubs, transport lines, and areas where daily services make renting simpler. In practice, Limoges often rewards a “clean” strategy: a well-placed property, a solid tenant file, and impeccable condition. Profit is made less through speculation than through regularity.
The city of Perpignan and its high rental demand
Perpignan attracts for a very concrete reason: rental demand remains sustained there, with rents that hold up, while maintaining still reasonable purchase prices. As of March 1, 2026, MeilleursAgents places the average price of apartments at €1,889/m² (range €1,129 to €2,837/m²). This level is higher than Limoges or Mulhouse, but the rental potential holds its own, particularly in sought-after sectors close to amenities.
SeLoger indicates for Perpignan (January 2026 data) an average rent per m² around €11, with a reported variation of €8 to €18/m² depending on the location and type of property. This is a key point: in a city where rents “hold up”, gross yield can remain attractive even if the purchase price goes up. And this is often where mistakes are made: people look for the “lowest price”, when they should look for the “best price/rent pair, with real demand”.
Perpignan also has a university base: the University of Perpignan Via Domitia announces 9,500 students. This supports certain segments (small areas, furnished apartments, housing close to campus), but the city requires a fine reading of micro-neighborhoods: in Perpignan, two streets can tell two different rental stories. A winning strategy often consists of aiming for a property that is easy to re-rent, even if it means accepting a slightly lower gross yield on paper, but more robust once vacancy and costs are integrated.
The city of Le Mans and its stable profitability
Le Mans is often less “spectacular” in gross yield than the cheapest cities, but it offers stable profitability and a very exploitable pool of tenants. As of March 1, 2026, MeilleursAgents estimates the average price of apartments at €2,055/m². We are no longer in the ultra-accessible range, but we remain far from markets where profitability is crushed by the purchase price.
For rents, SeLoger shows in Le Mans (January 2026 data) an average price of around €11/m² (with a variation of €7 to €17/m² depending on the sector). This combination frequently allows for gross yields around 5.5–7% depending on the property and location, with a risk profile that is often better managed than in highly degraded markets.
Le Mans also benefits from a “mobility” argument that weighs on demand: the Paris–Le Mans connection can drop to 0 h 53 on the fastest journeys, according to SNCF Connect. This type of connectivity expands the pool of potential tenants (mobile professionals, temporary contracts, hybrid profiles). Add to this the student weight: Le Mans University announces 12,500 students. Result: the rental market is often more regular, and that is exactly what you look for when you want a rental investment that “runs” without surprises every six months.
The criteria that make a city profitable
The relationship between purchase price and rents
Rental profitability starts with a simple calculation, but it must be done properly. Gross yield is the annual rent divided by the purchase price (including fees if you want to be realistic). A studio apartment bought for €70,000 and rented for €450 per month generates €5,400 per year: this gives 7.7% gross… before charges, property tax, repairs, insurance, co-ownership fees, management, vacancy, and taxation.
This is precisely why the most profitable cities are often found where the purchase price remains "compressed" while rents do not collapse. In Saint-Étienne, for example, an average price of around €1,245/m² combined with rents that can exceed €10/m² in certain segments mechanically creates high gross yields. Conversely, in a very expensive city, even a high rent does not always compensate for the acquisition cost.
But gross yield is only a first step. What makes the difference is the transition to net yield, then net-net (after tax). Two operations showing the same gross yield can lead to very different results depending on the co-ownership, property tax, building condition, and rental strategy (unfurnished, furnished, flat-sharing). In reality, profitable cities are those where you keep a margin after the "real life" of a landlord.
Rental demand and speed of leasing
A city can be cheap and "profitable on paper," but difficult in practice if the property remains empty. Rental demand is what protects you from vacancy. And when it comes to profitability, one month of vacancy per year is already more than 8% of annual rents disappearing, not including the costs of re-letting.
The speed of leasing rarely depends on a single factor. The student market helps because it creates a recurring flow: Saint-Étienne mentions nearly 30,000 students, Limoges highlights more than 17,000 students, Le Mans announces 12,500 students, and Perpignan 9,500 students. This foundation does not prevent bad surprises, but it reduces dependency on a single local employer or a single economic dynamic.
What matters is the "rentability": a functional floor plan, a clean condition, acceptable energy performance, and a location that makes sense for a tenant (transport, shops, campuses, employment hubs). In the most profitable cities, a frequent mistake is believing that a low price compensates for everything. In practice, it's the opposite: the more sensitive the market, the more the location and quality of the property affect vacancy.
Urban projects that support demand
Investing in a profitable city is good. Investing in a profitable city that is transforming is often better. Urban projects, transportation, neighborhood renovations, and the creation of university or hospital hubs influence rental demand, sometimes decisively. The subject is less "trendy" than it seems: an improving neighborhood attracts more stable tenants, sometimes at a higher rent level, without necessarily causing the purchase price to explode immediately.
In 2026, another invisible "project" weighs heavily: the regulatory transformation around energy performance. The energy decency schedule provides that from January 1, 2025, a dwelling must have at least an F rating to be considered decent, then at least an E rating by January 1, 2028, and then at least a D rating by January 1, 2034, according to the Ministry for the Ecological Transition. This directly influences markets where old buildings are common: a city can be profitable, but some properties become "traps" if the EPC rating is too poor.
And since January 1, 2026, the DPE calculation has evolved: the electricity conversion coefficient has changed from 2.3 to 1.9, which can improve the rating of electrically heated homes, as explained by Bercy. For an investor, this means it is necessary to check a recent DPE and understand what it actually reflects. A profitable city can become even more so if part of the housing stock "moves up" a class without major renovations... but this should not serve as an excuse to ignore the actual thermal comfort and the tenant's energy bill.
Strategies for exploiting profitable cities
The strategy of small budget for high profitability
This is the most intuitive strategy: target a city where the purchase price is low, in order to obtain a high gross yield. Saint-Étienne and Mulhouse illustrate the idea well with average apartment prices around €1,245/m² and €1,162/m² as of March 1, 2026. At this level, an investor can start with a total budget (purchase + fees + small renovation budget) that remains lower than the price of a down payment in a major metropolis.
The trap is turning "small budget" into "small control". However, in these markets, the difference between a good and a bad investment often comes down to very concrete details: healthy co-ownership, controlled charges, facade/roof in good condition, decent common areas, absence of major heavy works voted on, and above all a property that rents out quickly. If you have to cut the rent by 10% to find a tenant, the theoretical yield evaporates.
The winning logic is to keep a margin for the unexpected. In the most profitable cities, profitability often comes from a low purchase price, but the quality of the building is more heterogeneous. A well-anticipated renovation budget is not a luxury: it is often the condition to prevent the cash-flow from turning negative.
The roommate strategy in student cities
Shared housing is not a magic formula, but it can significantly increase the total rent of a property, especially in university towns. The idea is simple: instead of renting a 2-bedroom apartment to a single household, you rent room by room to several tenants. In a market where student demand is structured, this can improve profitability... and reduce the risk of total vacancy, because a room that becomes vacant does not cancel out the entire rent.
The important point is to remain consistent with the local market. In Saint-Étienne, where the city mentions nearly 30,000 students, a well-located shared apartment can be filled without difficulty if the apartment is functional. In Limoges, with more than 17,000 students, the strategy can also work, provided you do not overestimate the acceptable rent budget. In Perpignan, the presence of 9,500 students offers a foundation, but some sectors will be more suitable than others depending on accessibility and the perception of the neighborhood.
The trade-off is management. A roommate arrangement means more contracts, more inspections, more turnover. If you want to exploit the most profitable cities via shared housing, you rarely earn "without doing anything": either you get involved, or you delegate, and this must enter into your net profitability calculation.
The strategy of small surfaces easy to rent
In most markets, studios and 1-bedroom apartments remain the most liquid assets: they target students, young professionals, people on the move, separations, first jobs. In a profitable city, this liquidity is precious because it limits vacancy and long re-rental periods.
The reasoning is concrete: if the average rent per m² is around €11/m² in Le Mans or Perpignan, a well-optimized small surface can be rented more easily than large outlying housing, especially if charges remain controlled. And in a city like Mulhouse, where SeLoger shows around €13/m² in certain sectors, small surfaces can offer a good compromise between profitability and demand.
The key is not to confuse "small" with "poorly designed". A dark, poorly laid out, energy-intensive or noisy studio will be difficult to rent, even at a good price. Conversely, a bright 20–25 m² unit, well-equipped, with a real kitchen and a real sleeping area, can rent quickly and limit negotiation. In the most profitable cities, small square footage is often the simplest tool to secure the occupancy rate.
The renovation strategy to increase rents
Renovation is a powerful strategy, but it must be managed as an investment, not as an intuition. The principle: buy a discounted property (often because it is run down), bring it up to the right standard (functional, aesthetic, efficient), then rent it faster and sometimes for more. In cities with low prices, the gain can be huge, because a small renovation budget can radically transform the attractiveness of the home.
In 2026, energy renovation becomes a central subject, not just to "look pretty", but to remain rentable in the long term. The Ministry of Ecological Transition reminds that energy decency criteria are tightening, with deadlines starting in 2025 and 2028. And a recent subtlety must be added: as of January 1, 2026, the DPE (Energy Performance Certificate) method has evolved with an electricity coefficient lowered to 1.9 (instead of 2.3), which can improve the rating of some electrically heated homes. This can influence your renovation decisions, but should not replace a "comfort and charges" approach: a home that rents well is also a home where the tenant doesn't go broke on heating.
Profitable renovation is that which targets the visible levers for a tenant: insulation when it is accessible, correct ventilation, modern kitchen and bathroom, storage, lighting, clean paint, and above all a layout that “lives well.” It is often these elements that move your advertisement from the status of “one more” to “the one visited first.”
The limits of highly profitable cities
The risk of local rental vacancy
High gross profitability can hide a simple risk: vacancy. In some markets, you can show 9–10% gross… because the purchase price is very low, but if the property remains vacant for two or three months, the real profitability drops sharply. Two months without a tenant is about 16.7% less annual rent, not counting the costs of re-letting.
That is why, in the most profitable cities, selecting the micro-sector is often more important than choosing the city itself. Saint-Étienne is profitable on average, but a poorly located property or one in a fragile co-ownership can become a "problem case" rather than an investment. Mulhouse offers a very low purchase price, but a cheap market doesn't prevent areas where demand is softer. Limoges and Le Mans, which are more "stable," can sometimes offer a slightly less spectacular gross profitability, but one that is more resistant over time.
In short: vacancy is not a detail. It is often the variable that separates an investor who sticks to their financing plan from an investor who suffers.
More demanding rental management
The higher the profitability, the faster we forget that real estate is an asset that needs to be managed. In very profitable cities, we more often encounter situations where turnover is more frequent (students, mobility), where the housing stock is more heterogeneous, and where co-ownerships require increased vigilance. This does not mean these markets are "bad," but that they require a more rigorous method.
Energy regulations also add a layer of complexity. It is no longer enough to rent out a "correct" looking home: it must also remain decent in terms of the DPE (Energy Performance Certificate) and upcoming deadlines. Since 2026, the reform of the DPE calculation can change the classification of certain homes heated by electricity. In practice, this requires verifying diagnostics, following updates, and anticipating work rather than undergoing it.
Ultimately, a profitable city does not forgive sloppy management for long. If you are looking for the most profitable cities for a rental investment, the goal is not just to display a good gross yield, but to build stable net profitability, compatible with your time, your risk tolerance, and market reality.
What to remember
The most profitable cities for rental investment combine an accessible purchase price with rents strong enough to generate a margin after charges, vacancy, and taxes. Saint-Étienne and Mulhouse stand out for their very low prices per square meter, Limoges for a reassuring balance, Perpignan for sustained rental demand, and Le Mans for stability strengthened by mobility and a student base. Profitability is rarely won at the "city" level: it is earned at the level of the neighborhood, the type of property, the strategy (small surface area, flat-sharing, renovation) and management that anticipates, particularly regarding energy performance and rules of decency.
