The French property market is going through a period of adjustment after several years of rising prices and tighter lending conditions. The High Council for Financial Stability (HCSF) caps the debt-to-income ratio at 35% of income, including borrower insurance, and the loan term at 25 years, with limited flexibility.
At the same time, regulations on the energy performance of homes are changing the factors involved in a buy-to-let purchase. Buying, selling or investing in 2026 means taking these constraints into account—not just the price per square metre.
Energy ratings and rental bans: the factor buyers overlook
Since 1 January 2025, homes in mainland France with a G rating on the energy performance certificate (DPE) can no longer be offered for rent. F-rated and then E-rated properties will follow according to the statutory timetable. For an investor, this changes the very nature of the project: an F-rated property bought at a discount is only a good deal if the renovation work is technically and financially feasible before the deadline.
The pitfall often lies in co-ownership. An individual buyer cannot decide alone on work to the roof, façade or communal heating system. A refusal or postponement at a general meeting can prevent the property from being brought up to standard for years. Consulting Oh Brico’s property advice can help you identify the work to plan for and its impact on the profitability of a rental investment.
Before signing a preliminary sale agreement for a property intended for rental, two checks are essential:
- The current DPE rating and the type of work needed to achieve at least a D rating, distinguishing between work within the individual unit (windows, internal insulation) and communal work (façade renovation, roofing, central heating)
- The minutes of the latest co-ownership general meetings, which show whether energy-efficiency renovations have been approved, rejected or simply postponed
- The co-ownership’s renovation fund and projected service charge calls, which give an idea of the collective budget available
Mortgage borrowing capacity: what the advertised rate doesn’t tell you
Comparing the nominal rates offered by two banks is not enough to assess whether a purchase is feasible. The APR (annual percentage rate) includes borrower insurance, application fees, guarantee fees and the cost of the property valuation. It is the only indicator that allows a reliable comparison between two loan offers.
Borrower insurance accounts for a significant share of the total cost of a loan. Since the Lemoine law came into force, borrowers have been able to switch policies at any time, creating real scope for negotiation. A borrower who focuses solely on the nominal rate and overlooks insurance could miss out on savings of several thousand euros over the life of the loan.
The HCSF’s 35% debt-to-income cap includes this insurance. A household already spending 33% of its income on repayments before insurance may exceed the threshold once insurance is added and have its application rejected. Checking this calculation in advance, before even viewing properties, avoids wasting weeks on a project that cannot be financed.
Down payment and additional costs
Notary fees make up a significant part of the overall budget and are higher for existing properties than for new builds. Guarantee fees (mortgage or surety bond) and any initial renovation work must also be factored in. A realistic purchase budget includes these costs from the outset, not after signing the preliminary agreement.
A down payment remains a factor in banks’ lending decisions, even though the law sets no minimum amount. A down payment that covers at least the additional costs reassures the lender and makes it easier to secure more favourable rates and insurance terms.
Estimating the sale price: the margin of error that can prove costly
For sellers, setting the asking price determines how long a property takes to sell and the final sale price. An overpriced property languishes on the market and often ends up selling below its true value after several successive price cuts that undermine buyers’ confidence.
Public databases such as DVF (Demandes de valeurs foncières) let you check actual sale prices in a given area. These factual benchmarks are more useful than an estimate based on a neighbour’s property advertised in an estate agency window, which may not reflect the actual transaction price.
For sellers, comparing at least two or three valuations (an online tool, an estate agent and a notary) reduces the risk of mispricing against the market. The average scope for negotiation varies by area and market conditions, but setting the right price from the outset shortens the time to sell and reduces financial uncertainty—especially when another purchase depends on the sale proceeds.
Buying and selling at the same time: timing is the main risk
Buying and selling simultaneously creates a risk of timing mismatches. Selling first provides a clear picture of your finances but means finding temporary accommodation. Buying first requires a bridging loan, which adds to the overall budget and has a limited term.
Neither option is universally better than the other. The choice depends on how competitive the local market is, the estimated time to sell and your ability to manage two sets of costs at once. In a market where properties sell within a few weeks, selling first carries little risk. In a slower market, a bridging loan can become a significant source of financial pressure.
One point that is rarely anticipated is the sale contingency clause in the purchase agreement. It protects the buyer-seller by making the purchase conditional on completing the sale, but makes the offer less attractive to the seller, especially when competing against an offer without this condition. Negotiating this clause requires an understanding of the local balance between supply and demand.
Planning a property project depends on practical factors: the DPE rating, financing feasibility, the right price and the sale timeline. Any one of these can turn a viable project into a financial dead end—or, conversely, transform an opportunity that seems risky into a sound purchase.
