Real estate investment refers to the acquisition of a property with the aim of generating rental income or a capital gain upon resale. In 2026, the market is going through a particular phase: housing credit production rebounded by nearly 30% in 2025, according to the Banque de France, but this rebound primarily benefits owner-occupiers, not rental investors. Understanding this dynamic before embarking on a first purchase changes the approach to buying.
EPC and thermal sieves: the regulatory filter that beginners underestimate
Since January 2025, properties rated G in the energy performance diagnosis can no longer be rented out. Properties rated F will follow in 2028, and those rated E in 2034. For a beginner investor, the EPC directly conditions the ability to rent a property.

Buying an old apartment at a good price without checking its energy label exposes one to a costly scenario: mandatory renovation work before any rental can take place, several months without receiving rent, and an additional budget that is difficult to anticipate.
Properties rated E or F are often negotiated below market price. This is a real opportunity, provided that the cost of energy renovation is integrated into the financing plan from the start. Without this projection, the profitability shown on paper does not correspond to the actual profitability. Several resources allow for assessing available properties based on their rental potential, notably on the Public Immo site, which lists investment opportunities in various geographical areas.

Mortgage credit in 2026: more selective access for rental investment
Rates have stabilized after the decline that began in 2024. Banks are lending again, but they clearly distinguish between primary residence applications and rental investment applications. The maximum debt-to-income ratio remains set at 35% of income, including insurance.
For a first investment, banks often require a contribution covering at least the notary fees and guarantee fees. The time when one could finance a rental investment at 110% without difficulty is over.

A rarely discussed point: projected rental income is only taken into account at 70% in the calculation of borrowing capacity. In other words, an estimated rent of 800 euros counts for only 560 euros in the bank application. This discrepancy reduces actual borrowing capacity and forces an adjustment of the acquisition budget downward.
Rental profitability: calculate net yield before signing
Gross profitability is calculated by dividing the annual rent by the purchase price, including fees. This figure, often highlighted in listings, does not reflect reality. Only the net yield, after expenses, property tax, and taxation, measures actual performance.
The items to deduct from gross rent to obtain net yield are more numerous than one might think:
- Property tax, which varies significantly from one municipality to another and can represent one to two months of rent in certain medium-sized cities
- Non-recoverable co-ownership charges from the tenant (facade renovation, major maintenance, management fees)
- Non-occupant homeowner insurance, mandatory for any landlord
- Periods of rental vacancy, meaning months without a tenant between leases
- Taxation on rental income, which depends on the chosen regime (micro-property or real regime)
A property advertised with attractive gross profitability may turn out to be mediocre once these items are integrated. The difference between gross and net frequently exceeds two percentage points.
Tax regime for rental income: micro-property or real regime
In unfurnished rentals, two regimes coexist. The micro-property regime automatically applies if annual rental income remains below 15,000 euros. It grants a flat-rate allowance of 30% on received rents. Simple to declare, it is suitable for investors whose actual charges are low.
The real regime allows for the deduction of all actual charges incurred: loan interest, work, insurance, management fees. For an old property requiring renovation work, the real regime often generates a tax deficit that can be offset against global income, within the limits set by law. This mechanism reduces income tax for several years.
The choice between these two regimes is made at the time of the first declaration. Opting for the real regime commits for a minimum of three years. Simulating both options before purchase helps avoid a tax error that will weigh on net profitability for the entire duration of the commitment.

Investors retreating from new builds: what this means for beginners
In Île-de-France, investors accounted for only about 16% of new housing sales in the first half of 2026, compared to nearly double that on average over the past ten years, according to the Centre for Real Estate Analysis and Forecasting (Capem). New programs are now primarily designed for first-time owner-occupiers.
For a beginner, this situation has two concrete consequences. The competition among investors is decreasing, which may open up negotiation margins on certain lots. At the same time, new properties are optimized for occupancy, not for rental yield: larger surfaces, comfort-oriented features, higher price per square meter. The rent/purchase price ratio is mechanically lower than in renovated old properties.
Old properties requiring work remain the segment where net yields are highest, provided that one masters the energy renovation aspect and chooses a location where rental demand is strong. The shortage of rental housing in many French urban areas maintains rental pressure that secures income, but does not exempt one from analyzing rental vacancy on a neighborhood-by-neighborhood basis.
The first real estate investment is less about intuition than about three technical arbitrations: the EPC of the targeted property, the chosen tax regime, and the honest calculation of net yield. A well-constructed spreadsheet protects better than a crush.
