The French property market is going through a period in which every purchase, sale or rental project faces a variable that has become central: a home’s energy performance. The rules governing the energy performance certificate (DPE) now determine access to the rental market, influence sale prices and affect financing decisions. Understanding how these constraints fit into a property project’s timeline can change the way you make decisions.
Energy renovation and property timelines: the factor that shifts everything
A purchase or sale is no longer determined solely by the price per square metre or the location. When a property has a DPE rating of F or G, the seller knows the pool of potential buyers will shrink: banks factor renovation costs into their assessment of disposable income, and some buyers walk away because they cannot get a clear picture of the actual cost of the work.
For buyers, the renovation budget must be estimated before signing the preliminary sales agreement. Waiting until the final deed is signed to request quotes can lead to surprises that may jeopardise the financing plan. An energy audit carried out in advance helps identify priority areas (loft insulation, replacing the heating system, ventilation) and negotiate the purchase price accordingly.
For landlords, the timeline is even more restrictive. Properties rated G are being gradually banned from the rental market. Selling before carrying out renovations often means accepting a lower price, while renovating without knowing how regulatory thresholds may change is a gamble. The information available in ileeo’s property section makes it possible to compare listings with market data and assess the actual impact of a property’s DPE rating on prices in a given area.
Buying a property: what mortgage rates don’t tell you about your actual borrowing capacity
Changes in mortgage rates dominate public debate, but the nominal interest rate reflects only part of the total cost of buying a property. Mortgage insurance, notary fees, property tax and service charges all affect your actual borrowing capacity. Buyers who rely solely on an online estimate based on the interest rate risk overestimating their budget.
Two costs are regularly underestimated:
- Notary fees, which vary depending on whether the property is new or older. For older properties, they make up a significant share of the purchase price and, in most mortgage arrangements, must be paid from personal funds.
- Energy-efficiency upgrades, which are added to the asking price and are not always included in the main mortgage. An additional loan (an eco-PTZ or renovation loan) may be available, but it extends the repayment period.
- Service charges, particularly when a multi-year works plan has been approved. The mandatory works fund introduced under the ALUR law increases quarterly payments.
Before making an offer, requesting the building’s maintenance log and the minutes of the last three general meetings gives you a reliable picture of upcoming expenses.
Selling a property and the DPE: setting a price that reflects its energy rating
Setting a sale price based on recent transactions in the neighbourhood without taking the property’s DPE rating into account can lead to a lengthy time on the market. A property rated D will not sell at the same pace as one rated F, even if they have comparable floor areas and locations.
Energy-related price reductions and room for negotiation
Buyers and their brokers now calculate the price reduction based on the estimated cost of work needed to achieve at least a D rating. A seller who provides an energy audit with detailed quotes reduces the scope for negotiation by removing uncertainty about the actual cost of the work. Without this document, buyers build in a safety margin that rarely works in the seller’s favour.
The possibility of regulatory changes makes the calculation even more complicated. Rental ban thresholds and DPE calculation methods have already been adjusted in the past. A seller who anticipates that their property might be reclassified following a change to the calculation method is taking a risk: there is no guarantee the adjustment will work in their favour or that the regulatory timeline will remain stable.
Renting and regulatory requirements: letting a property without unpleasant surprises
For landlords, rental profitability depends as much on rent levels as on continuous occupancy. If a property no longer meets energy-efficiency standards between tenancies, it can result in an unplanned vacancy, with no rental income while fixed costs continue to accrue.
Planning ahead for rental ban thresholds
The least energy-efficient properties are being gradually excluded from the rental market. For a landlord who owns a property rated E, the question is not whether renovations will be needed, but when. Scheduling renovations between tenancies avoids having to rehouse a tenant during their lease and makes it possible to arrange financing without rushing.
Three points should always be checked before putting a property up for rent:
- Whether the current DPE is valid, as its validity period may vary depending on when it was issued and on any methodological changes introduced by the authorities.
- Any rent controls that apply in the municipality, which may limit the extent to which renovation costs can be reflected in the rent.
- Available renovation grants (MaPrimeRénov’, energy-saving certificates), whose eligibility requirements and amounts are regularly revised.
Checking each grant scheme at the time the work is due to begin remains the only reliable approach, as the rates published one year do not guarantee the same rates will apply the following year.
Whether you are buying, selling or renting out a property, its energy performance has become a negotiating factor in its own right. Factoring in the cost and timing of renovations from the search or valuation stage helps prevent budget overruns and regulatory roadblocks. The most secure property project is one that treats energy renovation not as an afterthought, but as part of the price.
