A real estate project is not just about finding an appealing listing or putting up a “for sale” sign in front of your home. Buying or selling a property involves months of procedures, a significant budget, and decisions that impact several years. The difference between a smooth transaction and a chaotic journey often comes down to a few choices made in advance, well before the first visit or the signing at the notary’s office.
EPC and thermal sieves: a decisive criterion for buying or selling
Have you spotted a house at an attractive price classified as F or G in the energy performance diagnosis? This low price is not a coincidence. Since January 1, 2025, properties classified as G are banned from being rented out for any new lease in mainland France. Properties classified as F will follow on January 1, 2028, and those classified as E on January 1, 2034.
For a buyer, this means that an energy-consuming property purchased today without renovation work will not be able to be rented out in the medium term. A property classified as F or G suffers a significant depreciation at the time of sale, and this depreciation directly reflects the cost of the necessary work.
For sellers, putting a poorly rated property on the market without anticipating the EPC issue exposes them to very aggressive negotiations. Some buyers systematically deduct the estimated cost of insulation work. Others walk away. Having an energy audit done before putting the property up for sale allows for estimating the necessary interventions and sometimes making a few inexpensive improvements that change the property’s classification.
The listings published on directimmobilier.net display the EPC class, allowing you to quickly filter properties based on this criterion during your searches.
Sale price estimation: the foundation of a realistic real estate project
Why do some properties remain online for months without finding a buyer? In most cases, the listed price is too high compared to the local market. A reliable estimation conditions the entire project, whether you are a seller or a buyer.
How to avoid a biased estimation
A property owner naturally tends to overestimate their property. They have lived there, know its qualities, and forget its flaws. Online estimation tools provide a first range, but they do not take into account the actual condition of the property or the specifics of the neighborhood.
Consulting two or three professionals for cross-checked value opinions remains the most reliable method. Compare their arguments, not just their figures. An agent who justifies their estimation with recent comparable sales in the same area inspires more confidence than another who announces a round price without explanation.
For buyers: check the consistency of the asking price
Before making a purchase offer, consult databases of recent transactions in the targeted neighborhood. The price per square meter can vary significantly from one street to another. Comparing the asking price to recent actual sales protects against overvaluations.
The real estate market has stabilized with a slight upward trend in apartment and house prices, which reduces negotiation margins compared to periods of marked decline.
Real estate financing: preparing your file before searching for a property
Many buyers start by visiting properties and then deal with financing. It’s the opposite that works. Knowing your actual borrowing capacity before any visit avoids disappointments.
- Gather your last three pay slips, your last two tax notices, and your bank statements from the last three months. These are the documents that any bank will request first.
- Calculate your current debt ratio, including all your ongoing loans. Lenders apply a strict ceiling, and exceeding it even slightly blocks the application.
- Request a principle agreement from your bank or a broker. This document, even if non-binding, shows sellers that your offer is based on credible financing.
- If you already own a property and are buying before selling, inquire about a bridging loan. This mechanism allows for temporarily financing the new purchase while waiting for the sale of the current property, but it comes with a cost and a risk if the sale is delayed.
Sell before buying or buy before selling: which order to choose
This choice depends on your tolerance for financial risk and the tension in the local market.
Selling first offers certainty: you know the exact amount available for your next purchase. The downside is the pressure to find a new home within a constrained timeframe, sometimes requiring temporary rental.
Buying first assumes a double financing capacity for a few months. If your current property sells quickly, the transition is smooth. If the sale drags on, the monthly payments of the bridging loan accumulate.
A third option exists: negotiate a long sale clause with the buyer of your current property. This gives you several months to find and finalize your next purchase without resorting to double financing.
Mandatory diagnostics and documents to prepare for the sale
An incomplete diagnostics file delays the signing of the compromise and can scare off a rushed buyer. Here are the elements to gather as soon as you put the property up for sale:
- The EPC, now legally enforceable, must be carried out by a certified diagnostician. Its validity period is ten years, unless work modifies the performance of the property.
- The asbestos diagnosis concerns properties for which the building permit was issued before July 1997.
- The state of natural and technological risks, updated every six months, informs the buyer about the risks related to the property’s location (flooding, earthquakes, soil pollution).
Preparing these documents before the first visit speeds up the transaction. A buyer who receives a complete file as soon as they inquire perceives an organized seller, which enhances trust and limits late renegotiation attempts.
The moment a real estate project derails is rarely at the signing. It is almost always upstream, when an estimation has been rushed, financing poorly calibrated, or a diagnosis forgotten. Preparing each step before it becomes urgent remains the best lever for buying or selling without unpleasant surprises.
