Overall context of the French real estate sector in September 2026

Macroeconomic situation and climate of the French real estate market in September 2026

The start of autumn 2026 comes in a mixed economic climate. After reaching 1.8% year-on-year in June, compared with 2.4% in May according to INSEE, French inflation remains closely monitored, in a context of strained public finances: public debt reached around €3,559 billion at the end of August 2026, equivalent to 118.3% of GDP, and the 2026 deficit is estimated at between 4.9% and 5.3% of GDP according to various institutions. This situation weighs on bond-market confidence, with the 10-year French OAT yield reaching around 4.10% in mid-August, its highest level in several years. For households in France, employment remains broadly resilient, but confidence remains cautious, weighing more heavily on transaction volumes than on prices themselves.

Evolution of French mortgage rates in September 2026: best rates, average rates and rate scale

After the ECB raised its key interest rates in June 2026, the first increase in three years, then confirmed a pause on 23 July, mortgage rates in France remain broadly stable in September, with slight variations depending on the loan term. Here are the benchmarks observed this month:

The “lowest rate” refers to the best offers granted to the strongest borrower applications. The “average rate” reflects the practice observed across the French market as a whole. The “market rate scale” corresponds to catalogue grids before negotiation. Over the past six months, the trend has been near-stability on shorter terms and a slight increase on longer terms, while catalogue rate scales have remained unchanged since the summer.

Borrowing capacity and real estate purchasing power in France in September 2026

Borrowing capacity depends on the amount borrowed, the interest rate, the loan term, the personal contribution and existing charges. The usual rule applied by French banks remains an effort ratio close to 35% of net income. Additional costs must also be factored in: notary fees, around 7% to 8% in the existing-home market in France, possible agency fees, renovation work and borrower insurance, all of which reduce real purchasing power.

Repayment capacity and personal contribution: a quantified example

Let’s take the example of a 35-year-old household with €4,500 in net monthly income, a €30,000 personal contribution and a €300,000 project financed over 20 years, i.e. a €270,000 loan. At the lowest September 2026 rate, 3.10% over 20 years, the monthly payment is around €1,511 per month, excluding insurance. At the average rate, 3.34%, it rises to around €1,544. At the market rate scale, 3.84%, it reaches around €1,613. With a debt threshold of 35%, this household has a maximum repayment capacity of around €1,575 per month: it therefore remains eligible at both the lowest rate and the average rate, and retains a reasonable safety margin even at the market rate scale.

Renegotiation and refinancing in France in September 2026

Renegotiating or refinancing a mortgage may be relevant if the rate gap is large enough to absorb the costs incurred, such as early repayment penalties, application fees and guarantee fees. In practice, a gap of 0.7 to 1 percentage point is often necessary for renegotiation to be profitable, taking into account the remaining term. Delegated borrower insurance remains a savings lever that is often underused by existing borrowers.

Evolution of sales and transaction volumes in France in September 2026

Comparative transaction overview: autumn 2026 and 12-month assessment

The existing-home market in France saw an improvement at the start of 2026, with 958,000 transactions over twelve rolling months at the end of February, before falling back to 941,000 at the end of April, representing a loss of 17,000 sales in two months. Fnaim now expects a landing between 900,000 and 920,000 transactions for 2026 as a whole, which would represent a 5% to 6% decline compared with 2025. September, traditionally more active after the summer pause, will be closely watched to confirm or challenge this end-of-year trend.

Transaction segmentation: houses vs apartments in France in September 2026

The decline in existing-home prices in France is mainly driven by individual houses, down 0.9% year-on-year, while apartments remain close to stability, down 0.3% year-on-year. This difference reflects a more pronounced adjustment for larger properties, which are more sensitive to the higher cost of credit, while demand for small and medium-sized urban properties remains broadly supported.

Urban areas vs rural areas: disparities in the French real estate market in September 2026

National averages mask very different trajectories depending on the territory. Paris and the Île-de-France region seem to be finding a floor after several years of continuous correction. Coastal markets continue to resist well, supported by structural demand. Conversely, some major cities such as Lyon and Bordeaux continue to adjust, with cumulative decreases of 6% to 9% from their peak. Attractive medium-sized towns and rural areas, meanwhile, retain a good balance between price and quality of life, strengthened by the partial continuation of remote work.

Real estate price trends in France in September 2026

At national level, prices for existing homes in France are down slightly, by around 0.6% year-on-year at the end of July 2026 according to preliminary contracts from the Notaires de France, after near-stability observed in the first quarter. This figure confirms a key message for the start of autumn: the market is tightening today more because of financing conditions and buyer selectivity than because of a generalised price correction.

Property prices in major French metropolitan areas: Paris, Lyon, Marseille, etc.

In Paris, the average apartment price stands at around €9,840/m² in 2026, down around 12% from the peak of €11,180/m² reached in 2023, with strong disparities depending on the arrondissement, around €8,000/m² in the 19th compared with more than €14,000/m² in the 6th. Lyon shows an average price of €4,593/m², ranging from €3,108 to €6,014 depending on the neighbourhood, and continues to adjust. In Marseille, the average price reaches €3,492/m² across all property types, with around €3,294/m² for an apartment and €4,928/m² for a house.

Property prices in rural French municipalities and small towns

In rural municipalities and medium-sized towns in France, prices remain significantly lower than in major metropolitan areas, offering an interesting entry point for first-time buyers and investors. These areas, strengthened by the appeal of partial remote work, continue to attract households looking for space and greater real estate purchasing power, with markets generally more stable than in major urban areas.

Property supply and available stock in France in September 2026

The stock of available properties remains moderate at the start of autumn 2026. Some owners continue to delay listing their property for sale while waiting for greater visibility on rates and prices, which maintains a degree of tension on the best-presented and best-priced properties.

Time on market and sale timeframe in France in September 2026

In urban areas and attractive sectors, correctly priced properties continue to sell within a few weeks. In rural areas or for properties requiring work, the sale timeframe can lengthen significantly. An overvalued price or an incomplete diagnostics file remains the main cause of longer timeframes observed by advisers in the network.

Practical advice for sellers in France in September 2026

•
Free property valuation: start with a realistic valuation carried out by a local adviser.

•
Exclusive mandate: recommended for a coherent marketing strategy and better visibility.

•
Home staging and professional photos: effective levers to reduce the sale timeframe at the start of autumn.

•
Optimised listing: clear description, local keywords and distribution on the main property portals.

French real estate market trends in September 2026 by buyer profile

The market reads differently depending on the buyer profile. First-time buyers, investors and buyers of main residences or second homes do not have the same priorities or financing constraints.

First-time buyers: access to the French market in September 2026

First-time buyers can access the market if they prepare a strong application: personal contribution, income stability and guarantees significantly improve bank acceptance. The 2026 PTZ reform, now open to a fourth income bracket and able to finance up to 50% of the transaction in eligible areas, is an important lever not to be overlooked.

Rental investors: yield and opportunities in France in September 2026

Rental yield depends heavily on location and property type. For example, a €200,000 purchase generating rent of €850 per month offers a gross yield of around 5.1%, most often reduced to between 2.5% and 3.5% net after charges and taxation. Investors must include rental vacancy, renovation costs and the chosen tax regime, such as micro-foncier, régime réel or LMNP, in their profitability calculation.

Main residence buyers vs second-home buyers in France

A main residence prioritises proximity to services and local employment, while a second home targets tourist or coastal areas more often. For a short-term rental project in France, it is essential to study the expected profitability and applicable taxation in advance before committing.

New-build and construction market in France in September 2026

Housing starts and building permits: where does the French new-build market stand?

The new-build construction sector in France is sending mixed signals at the start of autumn 2026. Housing starts are up 17.3% year-on-year at the end of June, with 296,600 homes accumulated, a clear rebound after several difficult years. However, building permits are down, with 30,906 permits issued in June, down 4.8% month-on-month and 11.8% year-on-year, and the twelve-month rolling total, 376,241 authorised homes, remains around 8% below the average of the past five years. This gap between rising housing starts and falling permits raises concerns about a slowdown in the flow of new housing in the medium term if the trend in permits does not reverse.

Regulation, taxation and support schemes in France in September 2026

New-build housing in France remains governed by the RE2020 standard, which influences property value and energy consumption. The zero-interest loan, known as the PTZ, extensively reformed for 2026 and extended until 31 December 2027, now finances up to 50% of a transaction and once again finances new-build detached houses throughout the country. Mandatory diagnostics, such as DPE, lead and asbestos reports, continue to condition sale listings, in both the new-build and existing-home markets.

Outlook and forecasts for the French real estate market for the end of 2026 and 2027

Three scenarios can reasonably be considered for the remainder of the year and the start of 2027, depending on the trajectory of inflation, ECB policy and the French budgetary context.

Optimistic scenario: gradual easing from 2027

A confirmed decline in inflation towards the 2% target and the adoption of a 2027 budget deemed credible by the markets would help ease pressure on OAT yields and mortgage rates, with the average 20-year rate gradually returning towards 3% from mid-2027, supporting a recovery in transaction volumes.

Cautious scenario: stabilisation of prices and rates, the most likely scenario

The ECB extends its monetary pause, mortgage rates move within a narrow corridor and national prices in France remain broadly stable, with localised adjustments. Transaction volumes remain around 900,000 to 920,000 sales for the year, in line with Fnaim forecasts.

Pessimistic scenario: renewed pressure under the effect of budgetary risk

A further deterioration in France’s budgetary situation, a new rise in the OAT yield beyond 4.2% or renewed inflation could force the ECB to tighten monetary policy again, weighing on household borrowing capacity and potentially accentuating the decline in transaction volumes beyond current Fnaim forecasts.

Concrete example: purchase simulation in France in September 2026

For a €200,000 loan over 20 years, excluding insurance, monthly payments vary significantly depending on the rate obtained:

•
Lowest 20-year rate, 3.10%: monthly payment of around €1,119 per month.

•
Average 20-year rate, 3.34%: monthly payment of around €1,144 per month.

•
20-year market rate scale, 3.84%: monthly payment of around €1,195 per month.

These amounts remain indicative orders of magnitude, calculated according to the standard annuity formula, excluding borrower insurance and additional costs. For a personalised simulation incorporating your full profile, contact an Optimhome adviser.
