Paris property market guide: prices, rents and rules for buyers abroad

The average asking price of an apartment in Paris is €11,804/m² in Q3 2026 according to CASAFARI Area Insights, 0.4% below a year earlier and 1.0% below the Q1 2026 peak. Signed deeds record less: the Notaires du Grand Paris put old-stock apartments at €9,530/m² in April 2026. Meanwhile, asking rents reached €48.1/m²/month (+5.7% year on year), giving an indicative gross yield of 4.9% before three local rules bite: 5% departmental transfer duty, a 90-day short-let cap and strict rent control.

What does an apartment in Paris cost in 2026?

Imagine a buyer from London or Milan standing in a 45 m² one-bedroom apartment in the 11th arrondissement, listed at €530,000. That figure matches the citywide asking average almost to the euro, yet it prompts two immediate questions for any international buyer or adviser: what will the final deed actually record, and what can the property legally earn?

Inside the Boulevard Périphérique ring road, single-family houses are marginal, so the Paris market is fundamentally an apartment market. According to CASAFARI Area Insights (location ID 464393, based on indexed listings with outliers excluded), the average asking price for a Paris apartment stands at €11,804/m² in Q3 2026. That is 0.4% lower than in Q3 2025 (€11,852.4/m²).

Looking back over the past four years, asking prices have remained remarkably steady. From €11,742/m² in Q1 2023 to €11,804/m² in Q3 2026 (+0.5% overall), the entire CASAFARI asking-price series has moved within a narrow band of roughly 4%. The market touched a trough of €11,458/m² in Q1 2024 (+3.0% since) and a peak of €11,923.8/m² in Q1 2026 (−1.0% since).

Why do asking prices and notarial prices differ by 20%?

While sellers ask €11,804/m² on average in Q3 2026, official transaction records show a lower figure. In France, every property sale passes through a public official known as a notaire, and the regional chamber (Notaires du Grand Paris, using the ADSN-BIEN database of signed deeds) publishes quality-standardised transaction prices with the national statistics institute, INSEE.

For old-stock apartments in Paris, the Notaires recorded a standardised transaction price of €9,600/m² in Q4 2025 (+1.4% year on year), followed by €9,530/m² in their February to April 2026 market note (+0.4% year on year). Based on signed pre-contracts (avant-contrats), their May to July 2026 market note projects a transaction price of about €9,600/m² in October 2026 (−0.5% year on year).

This gap of roughly 20% between asking prices and signed deeds is structural rather than a sudden discount:

• Stock composition: Active public listings skew towards renovated, upper-floor and prime apartments, which carry a higher €/m² price tag.
• Negotiation and timing: Asking prices reflect seller expectations at the start of marketing, before price reductions and buyer negotiation.
• Index methodology: The Notaires-INSEE figure is a hedonic, quality-standardised index of completed sales, whereas CASAFARI measures the live average of what is currently offered for sale.

Even on notarial deeds, the capital commands a substantial premium over its surrounding region. At the end of July 2026, the Notaires du Grand Paris price map placed the standardised apartment price across Île-de-France at €6,150/m² (−0.4% in one year, −9.5% over five years), leaving Paris proper about 55% above its regional average. In practice, advisers use CASAFARI asking data to read live supply and direction, and notarial data for historical anchors; running Comparables and a market study for a specific Paris address brings both perspectives together on a single street.

Are Paris prices rising or falling?

After a correction of roughly 8% on notarial deeds between mid-2022 and the end of 2024, Paris has settled onto a plateau. Both the Q3 2026 asking figure (−0.4% year on year) and the April 2026 notarial reading (+0.4% year on year) describe a market moving sideways.

Transaction volumes, however, require careful reading in 2026. Across Île-de-France, old-stock apartment sales rose 13% in full-year 2025 to 88,020 transactions. In early 2026, the year-on-year comparisons swung sharply because buyers had rushed to complete purchases before 1 April 2025, when Paris raised its departmental transfer tax (droits de mutation à titre onéreux, or DMTO). Because of that front-loading in early 2025, trade press quoting the Notaires' Q1 2026 conference reported Paris apartment sales down 13% year on year in Q1 2026, whereas Q2 2026 sales volumes jumped 20% in Paris (+10% across Île-de-France to 31,750 sales, including 23,070 apartments, +11%).

Neither quarter alone represents the underlying trend. The cleaner reading comes from the May to July 2026 window, where the Notaires recorded 36,810 sales across Île-de-France (+5% year on year) and a +4% increase in Paris. While mortgage rates have eased from their 2023–2024 peak, the Notaires still describe the recovery as fragile; you can compare this trajectory with wider property market trends across France.

Where do rents and yields stand for an investor?

While sale prices sit flat, asking rents are the series under upward pressure. According to CASAFARI Area Insights, the average asking rent for a Paris apartment reached €48.1/m²/month in Q3 2026, up 5.7% from €45.5/m²/month in Q3 2025. The series touched a low of €45.0/m²/month in Q1 2025 before jumping in late 2025, though Q3 2026 remains 4.2% below the Q1 2024 level of €50.2/m²/month.

Because asking rents rose over the past year while asking sale prices edged down, the indicative gross rental yield on Paris apartments stands at 4.9% in Q3 2026 (computed as 12 × €48.1 ÷ €11,804), up from 4.6% in Q3 2025 and compared with 5.3% in Q1 2024.

Paris is structurally a tenant city. According to the INSEE housing census 2022 for Paris, out of 1,125,473 main residences, 61.9% are rented (including 18.0% in social housing), against 33.4% owner-occupied and 4.8% housed free of charge. That keeps demand for studios and one-bedroom apartments constant, with furnished leases dominating the small-flat segment.

Professionals evaluating CASAFARI for investors should note two important caveats around that 4.9% figure. First, it is an indicative gross yield calculated on asking figures, before co-ownership charges, property tax (taxe foncière), vacancy and maintenance. Second, CASAFARI captures advertised asking rents, which include corporate lets or listings priced at the top of the legal envelope; under Paris rent control, the legally recoverable rent on a standard new lease may sit below the advertised market average, and flats with the worst energy ratings cannot legally be let at all.

Which arrondissements do second-home and prime buyers choose?

Paris spirals out from the Louvre across 20 municipal districts (arrondissements), and pricing divides sharply between the historic core and the eastern outer ring. According to figures from the Notaires du Grand Paris Q1 2026 press conference reported by Monimmeuble.com, standardised transaction prices ranged from €7,530/m² in the 19th arrondissement in the north-east to €14,060/m² in the 6th arrondissement (Saint-Germain-des-Prés, Luxembourg) on the Left Bank. Prime arrondissements—the 6th, 7th, 4th and 8th—held above €12,000/m² on deeds throughout the 2022–2024 correction.

These central districts are also where pied-à-terre buyers concentrate. Across Paris as a whole, INSEE's 2022 census counted 136,693 second homes and occasional dwellings, or 9.8% of the total housing stock, up from 8.7% in 2016 and 6.8% in 2011. In the 6th arrondissement, INSEE data for 2022 shows that second homes represent 22.1% of all dwellings (6,980 units), in a district where 66.6% of main residences were built before 1919.

An earlier INSEE study on second homes in Île-de-France (2016 census data, published in 2020) found that second homes made up 14% to 20% of the housing stock across the 1st to 8th arrondissements, compared with just 3% to 4% in the 19th and 20th. Four in ten Paris second homes actually belong to households living elsewhere in Île-de-France, alongside provincial French buyers and international owners.

Supply across the city comes almost entirely from resales of pre-1945 buildings rather than new construction. Meanwhile, the resident population is shrinking: INSEE legal populations for Paris record 2,103,778 inhabitants at the 1 January 2023 reference date (published December 2025), down from 2,240,621 in 2012.

What rules and costs should a buyer from abroad know?

France places no restrictions on foreign property buyers: non-residents purchase on the exact same legal terms as French citizens, with no purchase permit required and no golden-visa scheme attached to real estate. What shapes a Paris purchase instead are local taxes, letting caps and building regulations.

Rule or cost	2026 Paris framework	What it means for a buyer
Transfer duty (DMTO)	Departmental share raised from 4.5% to 5.0% from 1 April 2025 to 31 March 2028 (exempting first-time buyers of a main residence).	Total acquisition costs (frais d'acquisition, including notaire fees and taxes) on old-stock apartments run around 7% to 8% of the purchase price.
Short-term lets	Main residences capped at 90 days/year since 1 January 2025; registration number mandatory; unclassified micro-BIC tax allowance cut to 30%.	A second home cannot be let short-term on platforms without a commercial change-of-use authorisation with compensation, which is costly and rare in central Paris.
Rent control (encadrement des loyers)	Reference rents set by sector and flat type; ceiling is reference rent + 20% under the prefectoral order running 1 July to 24 November 2026.	Caps the starting rent on standard furnished and unfurnished leases; verify the legal ceiling for the exact street before underwriting a yield.
Energy rating (DPE)	G-rated dwellings banned from letting (both long-term and tourist lets) since 1 January 2025; F-rated dwellings follow in 2028.	Because most Paris flats predate 1945, check the Diagnostic de Performance Énergétique (DPE) and budget for insulation works.

As the Chambre des Notaires de Paris note on the 2025 transfer-duty rise explains, the extra 0.5 percentage point goes to the City of Paris rather than the notaire. On the letting side, the Ville de Paris 90-day short-let cap (tightened from 120 days on 1 January 2025 in a city counting over 95,000 declared tourist lets, 78,000 of them main residences) implements the national law of 19 November 2024 (loi Le Meur), detailed in the Ministry guide to tourist-let rules 2025.

For long-term lets, the DRIHL Île-de-France reference-rent orders for Paris (prefectoral order IDF-2026-06-12-00003 of 12 June 2026) govern leases signed between 1 July and 24 November 2026, the scheduled end of the Elan-law experiment.

Finally, almost every Paris apartment sits inside a co-ownership (copropriété). Major building liabilities—roofing, lifts, courtyard façades and shared energy upgrades—are rarely reflected in the asking price per square metre. Always request the minutes (procès-verbaux) of the last three annual general meetings before signing a preliminary contract.
