An appointment with a real estate agent is prepared like a technical file. Each visit requires time, energy, and sometimes travel expenses. The goal is not to “get an idea”: it is to collect enough verifiable information to decide whether the property deserves an offer or not.
Regulatory documents to request from the seller before the visit
Even before stepping through the door, part of the work is done based on the documents the seller must provide. The technical diagnostics file (DDT) includes the mandatory documents: energy performance certificate (DPE), risk assessment, electrical diagnosis, lead, and asbestos depending on the property’s age.
The risk assessment deserves special attention. It must be dated within the last six months and presented to the buyer during the first visit when required. If the seller has not prepared it, it’s a signal: either they are not well-informed, or the sale has been rushed.
Another often overlooked point: since January 1, 2025, the energy audit is mandatory for homes classified E, in addition to classes F and G already affected. Properties in co-ownership are not subject to this sales audit. Requesting this document in advance allows for preparing questions about thermal performance and anticipating a potential renovation budget.
To structure this document collection and not forget anything during your exchanges, practical tips on Immonex detail each step of the preparation.
Energy audit and DPE: two documents, two distinct functions
The confusion between DPE and energy audit consistently arises during appointments. The DPE assigns an energy class (A to G) and indicates estimated consumption as well as greenhouse gas emissions. The audit goes further: it proposes costed renovation scenarios, with a step-by-step work plan.
The audit informs the buyer; it does not obligate the seller to carry out the work. This point should be clarified during the visit. A seller presenting an audit with heavy renovation scenarios is not committing to financing them. The buyer uses this data to adjust their offer and financing plan.
Also check the consistency between the two documents. A DPE rated D with an audit recommending complete insulation of the walls and roof may indicate a real energy performance more fragile than the letter suggests.
Concrete questions to ask about energy
- The current heating method and its installation date, to estimate the remaining lifespan of the equipment
- The actual amount of energy bills over the last twelve months, more reliable than the theoretical estimates of the DPE
- The insulation work already completed and any corresponding invoices or certificates
Technical points to check during the property visit
Diagnostics do not replace direct observation. Some defects are not mentioned in any document and only reveal themselves through methodical inspection of the property.
Start with signs of moisture. Discolored lower walls, musty odors, blackened bathroom joints: these clues indicate problems with waterproofing or ventilation that can lead to costly repairs. The state of ventilation determines the durability of the entire structure.
Next, inspect the electrical panel. An old panel without a 30 mA differential circuit breaker indicates an outdated installation. The electrical diagnosis points out anomalies, but it does not require compliance upgrades before the sale. It is up to you to assess the cost of bringing it up to standard.
Elements often overlooked by buyers
- Water pressure: opening several taps simultaneously reveals potential flow or piping issues
- The condition of exterior joinery (windows, shutters), which represents a significant renovation item in case of complete replacement
- The actual orientation of living spaces concerning natural light, impossible to evaluate from photos
- The noise level at different times, especially for a low-floor apartment or one close to a road
Co-ownership and charges: documents to request before committing
For an apartment, the meeting with the seller should include a discussion about the co-ownership. The minutes of the last three general assemblies reveal the voted works, ongoing disputes, and the state of the works fund.
A voted facade renovation that has not yet been called represents a certain future expense. Request the building maintenance log and the amount of quarterly charges. Compare this amount with similar properties in the neighborhood to detect an underfunded co-ownership or, conversely, one that is well-managed.
The co-ownership regulations also deserve careful reading. Certain restrictions (prohibition of professional activity, limitation of facade modifications) can block a purchase project if they have not been identified in advance.
After the appointment: structuring your purchasing decision
Returning home with scattered notes on a phone is not enough. Each visit should produce a standardized sheet covering the same categories: condition of the building, energy performance, legal situation, amount of charges, anticipated works.
This sheet allows for objective comparison of several properties and avoids the halo effect: a beautiful layout or exceptional brightness does not compensate for a roof at the end of its life. Separating emotion from technical evaluation protects the long-term budget.
The displayed price is just a starting point. Each defect identified during the visit, each missing document, each anticipated work constitutes a negotiation lever. A buyer who arrives with a structured file and precise questions obtains more candid answers and negotiates on solid ground.
