A real estate project refers to all the steps that lead from identifying a property to its operation, whether it is a primary residence, a rental investment, or an investment through SCPI. Success depends less on intuition than on mastering three parameters: the applicable tax framework, the actual cost of credit, and the property’s ability to generate regular income over the long term.
Leverage effect of real estate credit: calculate before signing
Real estate investment stands out from other investments due to the possibility of borrowing a large part of the purchase amount. This mechanism, called the leverage effect of credit, allows one to build wealth with a limited contribution.

The principle is simple: if the net rental yield exceeds the total cost of credit (interest, insurance, processing fees), the difference constitutes a wealth gain financed by the bank and repaid by the rents. When rates rise, this gap narrows, sometimes even disappearing.
To assess the relevance of a project, one must compare the borrowing rate obtained with the net rental yield after expenses. A property with a net yield around the credit rate generates no surplus: the risk exists without compensation. Those who succeed in their real estate projects target properties where this gap remains significant, even after accounting for rental vacancy and foreseeable work.

Le Meur Law and short-term rentals: what changes for investors
Most rental investment guides treat the LMNP status as a stable asset. However, the Le Meur reform, enacted on November 19, 2024, profoundly alters the rules for Airbnb-type rentals.
Mandatory registration and penalties
Every furnished tourist accommodation must now be registered with the town hall via a national online service. A 13-character number is assigned and must appear on all listings. The fine for non-compliance can reach 10,000 euros.
EPC and schedule for excluding thermal sieves
The law mandates an energy performance diagnosis for furnished tourist accommodations. The schedule is progressive:
- Properties rated G are banned from tourist rentals starting in 2025, those rated F from 2028, and those rated E from 2034.
- From 2034, only furnished properties rated A to D will still be allowed to be rented for tourism, which excludes a significant portion of the unrenovated old stock.
- Co-ownership regulations established since November 21, 2024, must explicitly mention the authorization or prohibition of furnished tourist rentals, which can block purchasing projects in new developments.
An investor launching a rental real estate project in 2024 without integrating these regulatory constraints risks seeing their profitability collapse in the medium term. The cost of energy renovation work must be included from the financing plan stage.
SCPI and indirect real estate investment: an alternative to direct rental
Not all real estate projects involve purchasing a physical property. Real estate investment companies (SCPI) allow investment in real estate without managing tenants or renovations. The investor buys shares in a company that owns and manages a portfolio of properties (offices, shops, housing).
The yield of SCPI depends on the quality of the assets held and the rental management. Some SCPI specialize in health, logistics, or local shops, offering a sectoral diversification that is impossible to replicate by buying a single apartment.
The main risk lies in liquidity: selling SCPI shares takes time, sometimes several months, unlike a stock market investment. The price of shares can also decrease if the real estate market turns or if the occupancy rate of properties falls. Listed SCPI offer superior liquidity, but their price fluctuates with the financial markets.
For an investor who wants exposure to the real estate market without mobilizing heavy credit or managing co-ownership, SCPI represents a coherent vehicle, provided one accepts a long investment horizon (at least eight to ten years to amortize entry fees).

Managing rental risk: vacancy, unpaid rents, and unexpected repairs
The advertised yield of a rental property almost never corresponds to the yield actually received. Three factors regularly diminish it.
Rental vacancy represents the months without a tenant. In tight areas, it remains low. In medium-sized cities or tourist areas out of season, it can reach several months per year. Each empty month directly impacts cash flow, especially when credit is short.
Unpaid rents constitute the second risk. A rental guarantee insurance (GLI) covers this aspect, but its cost, generally proportional to the rent, reduces net yield. Not subscribing to GLI amounts to betting on the solvency of each tenant.
Unexpected repairs (roofing, boiler, compliance updates) complete the picture. A reserve repair budget avoids pressured decisions. The co-ownership can also vote for heavy repairs at any time, and the landlord co-owner must pay their share.
Successfully investing in real estate in 2024 requires integrating these three variables into the profitability calculation from the property search phase, not after signing at the notary. A spreadsheet projecting cash flows over ten years, including a pessimistic scenario of vacancy and repairs, provides a more reliable view than a simple purchase price to annual rent ratio.
