A real estate project is measured less by the initial enthusiasm than by the discrepancies between what was planned and what actually occurs. Price discrepancy between the listing and the signing, discrepancy between the announced rate and the total cost of the loan, discrepancy between the displayed energy performance diagnosis (DPE) and the actual energy bill. Analyzing these gaps before committing changes the trajectory of a purchase or investment.
Energy performance and resale value: what the DPE changes about the price
The DPE ranking of a property now directly impacts its market value and its ability to secure financing. Banks and notaries observe a marked depreciation of properties classified F and G, while better-rated properties remain more liquid and easier to finance.

This phenomenon has intensified with the gradual tightening of the ban on renting out energy-inefficient properties that began in 2023. A property classified G intended for rental investment loses both its future yield and part of its heritage value.
| DPE Class | Access to Credit | Liquidity at Resale | Rental Allowed |
|---|---|---|---|
| A – B | Easy | High | Yes |
| C – D | Standard | Fair | Yes |
| E | Standard (sometimes conditional) | Variable depending on location | Yes |
| F | More difficult | Low without renovations | Restrictions in progress |
| G | Very difficult | Very low | Gradual ban |
The RE2020, fully in effect for housing since 2022, pushes buyers towards new high-energy-performance properties to anticipate energy and compliance costs. For those who wish to learn more about Tout Immo, the listings specify the energy ranking, which facilitates pre-selection.

A property classified F or G is cheaper to purchase but much more expensive to maintain. The energy renovation budget must be included in the financing plan from the outset, or else one may discover after signing that the project is no longer profitable.
Protection Clauses in VEFA: Securing a Purchase Off-Plan
Buying in VEFA exposes the buyer to a risk often underestimated: delivery delays. Tensions on construction materials and new environmental standards have lengthened construction timelines in recent years.
Consumer associations now recommend including specific clauses in the reservation contract that allow disengagement or obtaining enhanced penalties in the event of significant delays. This practice, particularly encouraged by UFC-Que Choisir, constitutes a concrete protection lever.
- Ensure that the contract specifies a firm delivery date, not just a vague quarterly range.
- Negotiate daily delay penalties higher than the legal minimum, indexed to the amount of rent the buyer must pay elsewhere in the meantime.
- Require a no-fee cancellation clause beyond a defined delay (six months, for example), with full restitution of the amounts paid.
The VEFA reservation contract is negotiated before signing, never after. Once the document is initialed, the margins for maneuvering are significantly reduced.
Local Climate Risk: A Price Criterion Still Under-Integrated
The geographical choice of a property is no longer limited to proximity to transport or shops. Areas exposed to flooding, drought, or clay shrink-swell are experiencing increasing pressure on insurance premiums and, ultimately, on property values.
Local climate risk is beginning to weigh on resale prices. The most informed buyers consult natural risk prevention plans (PPRN) and the state of risks and pollution (ERP) even before the first visit.
A property located in a clay shrink-swell zone may require reinforced foundations or costly drainage work. These expenses do not appear in the displayed price, but they materialize in the years following the purchase.
What to Check Before Visiting a Property
- Consult the ERP (state of risks and pollution) on the Géorisques site to identify natural, technological, and mining hazards.
- Check the history of natural disaster decrees in the municipality, which informs about the actual frequency of claims.
- Ask the insurer for a home insurance premium simulation for the exact address: the difference between two streets in the same neighborhood can be significant.
- Examine the communal PPRN to know if the land is buildable without restrictions or subject to technical prescriptions.
Mortgage and Borrower Insurance: Where Cost Gaps Are Hidden
The nominal loan rate is just one component of the total cost. Borrower insurance can represent up to one third of the overall cost of the loan. The delegation of insurance, which involves choosing an external contract rather than the one offered by the bank, remains the most accessible savings lever.
On the other hand, the suspensive clause for obtaining a loan protects the buyer in case of bank refusal. Its absence in a sales agreement would expose the buyer to losing their deposit if financing does not materialize.
Rates, APRC, and the Real Cost of Financing
The APRC (annual percentage rate of charge) includes application fees, insurance, guarantees, and any broker fees. It is the only indicator that allows for a reliable comparison of two loan offers. Comparing APRCs rather than nominal rates avoids choosing a seemingly cheaper loan that is burdened by additional fees.
Using a broker can help obtain negotiated conditions, but their compensation (fees or commission) must be included in the overall calculation. A broker who saves half a percentage point on the rate but charges high fees does not necessarily generate a net gain.
The data that best summarizes the solidity of a real estate project is neither the emotional appeal nor the expected yield: it is the gap between the anticipated total cost and the actual total cost once all items are added up, from the DPE to insurance, including renovations and climate risk.
