Buying or selling a property requires very different skills depending on which side of the transaction you are on. A buyer must calibrate their budget and track down the right property, while a seller must set a realistic price and prepare a complete diagnostic file. Understanding these two perspectives, even when you only experience one, avoids most of the blockages that can extend a real estate project by several months.
Energy audit and DPE: what changes concretely for a sale
Since January 1, 2025, the energy audit is mandatory for individual houses and buildings in single ownership classified E on the DPE, in addition to the already affected classes F and G. This extension results from decree n° 2024-405 of April 29, 2024.
Why does this point deserve your attention from the start of the project? Because the DPE has been legally enforceable since 2021. A buyer who notices a significant discrepancy between the stated label and the actual performance of the property can hold the seller liable.
Specifically, if you are selling a house classified E, you must now provide a detailed energy audit in addition to the DPE. This document lists the recommended renovation works, their estimated costs, and the expected performance gains. A well-informed buyer will use it to negotiate the price. A seller who anticipates these works (or adjusts their price accordingly) sells faster. On maestro-immobilier.fr, listings include this data to facilitate the reading of the file by potential buyers.

Real estate appraisal: setting a sale price suitable for the current market
The common reflex is to look at the prices displayed on listing portals. The problem is that these prices are asking prices, not signed prices. The gap between the two can be significant, especially in a market where the stock of properties for sale remains high.
A property overvalued by a few percent stays online for months without generating serious visits. Meanwhile, the seller misses the maximum visibility window of the first weeks of being on the market.
Comparing the right data for a reliable appraisal
Have you noticed that two identical apartments on the same street can sell for very different prices? The reason often lies in three factors that are not easily visible in a listing:
- The actual DPE label of the property, which directly influences the buyer’s ability to obtain favorable financing and weighs on the final negotiation
- The condition of the common areas in a co-owned building, as voted but uncompleted facade or roofing works deter cautious buyers
- The quality of the sales file (complete diagnostics, minutes of general meetings, absence of disputes), which reassures the buyer and accelerates the signing
A realistic appraisal cross-references actual sale prices (available from notaries) with these specific criteria of the property. The precise appraisal of the property conditions the entire sales strategy.
Real estate purchase and financing: preparing a solid file before searching
Many buyers start by visiting properties, then take care of financing. It’s the opposite that works. A serious seller will always prefer an offer accompanied by a financing certificate, even if it is slightly lower than an offer without a bank guarantee.
Borrowing capacity and contribution: laying the foundations of the project
Before any search, obtain an accurate simulation of your borrowing capacity from your bank or a broker. This document gives you a clear framework: maximum budget, monthly payment, loan duration.
A financing file completed before visits shortens the purchase timeline. The seller knows that your offer is credible. The notary can start the verifications earlier. And you avoid falling in love with a property out of budget.
The specific case of simultaneous buying and selling
Are you already a homeowner and wish to buy a new home before selling the old one? This scenario often involves a bridging loan. The principle is simple: the bank advances part of the estimated value of your current property to finance the acquisition of the new one.
The risk is equally simple: if your property does not sell within the expected timeframe, the interest on the bridging loan accumulates. The best protection remains a realistic estimate of the sale price (not optimistic) and a plan B if the sale is delayed.

Negotiating the real estate price: adapting your strategy to the context
The real estate market is going through a phase where the buyer has become demanding again. Properties that sell quickly are those whose price, DPE, and general condition leave no room for negotiation. Others suffer sometimes significant discounts.
For a seller, this means that they must anticipate the buyer’s objections before listing. A quote for works to improve the DPE, an up-to-date electrical diagnosis, a co-ownership report without unpleasant surprises: each document provided in advance reduces the buyer’s negotiation margin.
For a buyer, negotiation is not only about the displayed price. A property classified E or F with an unfavorable energy audit justifies a discount. An apartment whose co-ownership plans heavy works within two years does too. These elements can be found in the sales file, provided it is read in detail.
What really weighs in the negotiation
- The DPE and the energy audit, which quantify the cost of bringing the property up to standard
- The duration of the listing: a property online for several months signals a price that is probably too high
- The suspensive conditions of the purchase offer, which protect the buyer if the credit is refused or if a hidden defect appears
Negotiating based on documented facts produces better results than a simple request for a discount. On both the seller’s and buyer’s side, the file makes the difference.
A well-managed real estate project relies less on luck than on preparation. Up-to-date energy diagnosis, appraisal based on actual prices, secured financing before visits, complete file from the first offer: each step prepared in advance eliminates a risk of blockage later on.
