Heating diagnostic: how to negotiate the price of your future real estate in 2025?

Have you ever felt a discomfort while browsing real estate listings, where the promises of a very favorable energy performance diagnosis (DPE) contrast with your concerns about excessive heating bills? You are not alone. Many buyers today are questioning the reliability of energy diagnostics, the watchdogs of a rapidly changing real estate market. In 2025, these questions take on particular significance as property price negotiations become tighter, influenced by complex economic dynamics. Find out how to refine your search, understand the stakes of the DPE, and above all, take advantage of negotiation margins available to you.

The energy performance diagnosis: a crucial issue for the buyer

The DPE is at the heart of concerns when purchasing real estate. It assesses the energy consumption of a home as well as its impact in terms of greenhouse gas emissions. However, the DPE often causes confusion. An excellent DPE can be attractive, but behind some flattering scores, anomalies sometimes lurk. What to do then to avoid being influenced by an overly favorable diagnosis? Here are some steps to follow:

• Check the calculation method: Since the overhaul of the calculation method in 2021, numerous errors have been noted. It is essential to ensure the accuracy of the data used.

• Use verification tools: Solutions, such as the one developed by Ruben Arnold from KRNO, allow for analyzing the consistency of the DPE. Such software can quickly detect anomalies.

• Analyze the report: A DPE report should be clear and detailed. Make sure it includes information on renovations to consider.

The real estate market in 2024: a trend towards negotiation

In 2024, the real estate market began to turn: with a decrease in demand and a rise in credit rates, buyers faced unprecedented negotiation margins. The LPI-iad real estate barometer reported that negotiation margins reached an average of 8.5%, marking a 22% increase from 2023. This trend presents a major opportunity for buyers to obtain fairer prices.

The regions most conducive to negotiation

Negotiation margins vary significantly from one region to another. For example, some areas, like the Auvergne region, show impressive margins of 11.9% on apartments. In contrast, regions like Franche-Comté exhibit low margins, around 0%. Here’s a summary table of negotiation margins by region:

This disparity is explained by access to credit and the willingness of sellers to adjust their expectations. It is not uncommon that in tight markets, negotiation becomes more difficult. The buyer must then be strategic to seize opportunities.

The keys to successful negotiation in 2025

Negotiating the price of a property requires method and preparation. Here are some practical tips to help you approach this crucial stage concretely.

Prepare in advance

The first step is to inform yourself about the market. A good understanding of the going prices in your target area will help you convince the seller of the opportunity for a reasonable offer. Here’s how to prepare:

• Analyze recent sales: Check the prices of comparable properties that have sold recently. This will give you a solid basis for your arguments.

• Evaluate the DPE: If the DPE is poor, this may justify a price reduction due to the renovation work expected.

• Identify the seller's motivations: Knowing why the seller is selling their property can give you an advantage in negotiations.

Support your proposal

Once your preparation is done, it's time to present your proposal. Be clear and factual, emphasizing concrete elements:

• Present facts: Use all the data you have gathered to support your offer.

• Highlight improvement potential: If you’ve identified necessary or desirable work, mention them clearly to justify your offer.

• Stay open to discussion: Negotiation is a dialogue. Do not close the door to concessions.

Financial aids in 2025: support for improving energy efficiency

In addition to negotiation, it is crucial to look into the financial aids available for energy renovations. In 2025, several programs are in place to assist buyers and owners in their energy transition.

Support programs

Here are some of the aids you can consider during your search:

• Heating boost: The government encourages replacing aging equipment with higher-performing models through this program. More information on heating options can be found on their site.

• MaPrimeRénov’: This aid allows financing up to 90% of energy renovation work under certain conditions.

• Zero-interest eco-loan: This loan helps finance energy improvement work without interest fees.

Partner companies

Companies like Engie, Dalkia, and TotalEnergies assist individuals in their renovation projects, offering customized solutions.

Preparing your energy renovation project

If you plan to buy a property, it is also essential to draw up an energy renovation plan, especially if the DPE reveals a need for improvement. Here are some key steps:

• Evaluate heating options: Rather than renovating identically with an old system, explore more efficient alternatives such as condensing boilers or renewable energy systems.

• Consult experts: Companies like Siemens or Ferroli offer solutions tailored to the specific needs of such projects. Quality assurance and performance are paramount.

By anticipating your renovation projects, you will not only enhance your comfort but also increase your real estate investment.
