A real estate project is not just about finding a property and signing at the notary’s office. Between financial structuring, technical diagnostics, and rules that change every year, the margin for error is real. Here are the concrete points that make the difference between a controlled purchase and a forced one.
EPC and energy performance: the filter to check before any visit
Have you spotted an apartment listed at an attractive price? Before even visiting it, check its energy label. Since 2024, the methodology for the energy performance diagnosis (EPC) has been revised, particularly for homes under 40 m². Some properties previously classified in low categories have been automatically recalculated and may now move up a class.

This recalculation changes the game for both buyers and investors. A studio reclassified from G to F, for example, regains the right to be rented, which completely alters its potential yield.
The Climate and Resilience Law provides a progressive timeline for banning the rental of the most energy-consuming homes. G labels are affected first, followed by F. If you are buying to rent, check the EPC label and estimate the costs of energy renovation before signing the preliminary agreement. A poorly classified property without a planned renovation budget can become impossible to rent, leading to forced vacancy.

Usury rate and financing: what really blocks applications
Since the rise in interest rates that began in 2022, obtaining a mortgage requires more preparation than before. The mechanism of the usury rate plays a central role: it sets the legal ceiling beyond which a bank cannot lend.
In practice, when rates rise quickly but the usury rate is recalculated with a delay, some applications become technically impossible to finance. The borrower is solvent, the bank is ready to lend, but the legal framework blocks it. This phenomenon, known as the scissors effect of the usury rate, has excluded many buyers from the market in recent years.
How to secure your loan application
The HCSF standard requires that your monthly payments do not exceed one-third of your net income, with a maximum duration of 25 years (27 years for new builds with a deferral). Exceeding these limits makes the application unacceptable, regardless of your savings.
- Reduce your debt ratio before submitting the application: pay off an ongoing consumer loan if possible, as this frees up borrowing capacity.
- Provide a personal contribution covering at least the notary fees and guarantee fees, as banks rarely finance beyond the property price.
- Encourage competition among institutions or go through a broker who knows the acceptance criteria of each bank.
A well-prepared application stands out for its clarity. Clean bank statements for three months, complete supporting documents, clear financing plan: the bank finances rigor, not promises.
Actual acquisition costs: the budget that no one details enough
The listed price of a property represents only part of the actual expense. The so-called “notary fees” significantly impact the budget in older properties, much less so in new ones. But other costs are often underestimated.
- Loan guarantee fees (mortgage or bank guarantee) vary greatly depending on the chosen mechanism. A mutual guarantee generally costs less than a mortgage and allows for partial repayment at the end of the loan.
- Compliance works, particularly energy-related, must be included from the purchase offer. Requesting quotes before signing the preliminary agreement gives you a negotiation lever on the price.
- Property tax can vary from simple to triple from one municipality to another for an equivalent property. Ask the seller or the town hall for the exact amount.
- Co-ownership charges, if you are buying an apartment, sometimes include recently voted exceptional fund calls. Check the minutes of the last three general meetings.
Price negotiation: relying on facts
Negotiating is not about proposing a lower price in the hope that the seller will accept. An effective negotiation relies on verifiable elements: unfavorable EPC, works to be planned, price per square meter in the neighborhood, duration of the property’s listing.
A property online for several months often indicates a price that is out of sync with the local market. This information is public and serves as a factual argument during discussions.
Professional support: when and why to call on an expert
A real estate agent, a broker, or a notary do not have the same role, and not all are necessary in every situation. The agent knows the local market and can spot properties before they are listed. The broker optimizes the financial structuring. The notary secures the transaction legally.
Are you buying your primary residence in a city you know well? The agent is helpful but not always essential. Are you investing in another region with a specific tax structure? Professional support reduces the risk of costly errors.
A common pitfall is to multiply intermediaries without clarifying each one’s scope. Ask each professional what they cover exactly and what remains your responsibility. A search mandate with a property hunter, for example, incurs fees only in case of success, aligning their interests with yours.
The success of a real estate project rarely hinges on a single good decision. It is the accumulation of concrete verifications, from the EPC to financial structuring to reading the co-ownership minutes, that transforms a risky purchase into a solid acquisition.
