A developer announces a T3 at a listed price, but there are three identical units on the same floor. One faces the street, another the courtyard, and the third a party wall. Yet, the price per square meter is the same for all three. It is in this gap between the catalog price and the actual value of the unit that the negotiation for a new apartment takes place.
Security deposit and reservation contract: underestimated legal levers
Negotiation is often thought of solely in terms of discounts on the listed price. However, the reservation contract in VEFA offers concrete levers that most buyers are unaware of.
The security deposit is capped by law according to the timeline for signing the final deed. If the signing occurs within the year, the cap is 5% of the projected price. Between one and two years, it drops to 2%. Beyond two years, no security deposit can be required. This timeline directly alters your financial exposure and can be discussed with the developer.
Another rarely exploited point: the buyer has a ten-day withdrawal period after signing the reservation contract. If the final price exceeds the revised projected price by more than 5%, the deposit can be recovered under certain conditions. Knowing this rule before entering negotiations changes the dynamics of the discussion, as it reminds the developer that the buyer is not captive.
Before negotiating the price, one can also demand the presentation of the financial guarantee of completion or reimbursement, which protects in case of seller default. This document is not just an administrative detail: it is an integral part of contractual security. A developer reluctant to provide it quickly sends a signal about the solidity of the operation, and you can learn more on philippon-architecte.fr to delve into these legal aspects.
Unsold or completed new apartment: a unique negotiation case
The classic VEFA (off-plan purchase) is not the only scenario. Completed but unsold new housing constitutes a distinct category, with different negotiation rules.
A newly delivered apartment still in stock costs the developer money each month: charges, insurance, cash immobilization. The financial pressure increases over time, which opens a wider margin for discussion than on a project currently being marketed.
The main difference with VEFA lies in the sales regime. If the housing is completed, the sale falls under the common law of real estate sales, not the protective regime of VEFA. The guarantees are not the same, nor is the payment schedule. The buyer must check:
- If the ten-year guarantee and the guarantee of perfect completion are properly transferred to the buyer, along with the corresponding insurance certificates
- If any reservations at delivery have been lifted, as an unsold unit may have been delivered to the developer with uncorrected defects
- If the listed price includes or excludes parking, the cellar, and any equipment (fitted kitchen, home automation) that served as commercial arguments during the launch phase
On an unsold unit, the discount is not the only lever. One can negotiate the inclusion of a parking space, the covering of customization work (choice of finishes, addition of a partition), or a reduction in ancillary fees.
Price per square meter and local comparison: what averages don’t reveal
Comparing the price per square meter of a new program with the municipal average is a useful reflex, but insufficient. The average price of new collective housing in France reaches €5,209 per square meter (excluding parking and excluding VAT at the normal rate) according to the FPI Observatory in the first quarter of 2026. This figure masks considerable discrepancies from one neighborhood to another.
The same program can show real value discrepancies of over 15% between two units depending on the floor, orientation, view, and exterior surface. The catalog price does not always reflect these differences. A north-facing unit on the second floor, without a balcony, sold at the same price as a cross-unit on the fifth floor with a terrace, constitutes a factual negotiation argument.
To build a solid argument, one collects prices from competing programs within the same perimeter. Feedback on this point varies according to local markets, but in areas where several developers compete for buyers, competition between programs mechanically creates a margin for negotiation.
Elements to compare unit by unit
- The weighted price per square meter (living area plus share of annexes), not just the face price
- The services included in the price: type of heating, quality of joinery, floor coverings, kitchen equipment
- The actual cost of parking, often billed separately and negotiable
- The reduced notary fees in new builds, which represent an advantage to be included in the overall calculation but not a negotiation argument in itself
Timing of the negotiation: beginning and end of marketing a new program
The timing of the negotiation weighs as much as the arguments presented. At the beginning of marketing, the developer needs to pre-sell a significant portion of the program before starting construction. The first buyers represent financial security that the developer values, sometimes in the form of a direct discount, sometimes by offering additional services.
At the end of marketing, the logic reverses. The last unsold units weigh on the developer’s accounts. The pressure is different: it is no longer about reassuring a bank to unlock financing, but about liquidating a program to free up cash flow.
The intermediate period (program under construction, sales at the expected pace) is generally the least favorable. The developer has neither the urgency of starting nor that of closing. The margin for maneuver shrinks, and discounts often limit themselves to minor commercial gestures.
Negotiating the price of a new apartment relies less on oratory talent than on preparation. Checking the reservation contract, comparing the units with each other, identifying the marketing moment of the program: these concrete elements provide a framework for the discussion and allow for real adjustments, whether concerning the price, services, or contractual conditions.
