A statistic made the rounds this week, picked up almost everywhere: in the third quarter of 2026, under-40s accounted for 51.3% of Paris buyers, against 44.4% a year earlier. Commentators read into it a generation returning to the capital, a market opening up, a sign of normalisation.

Home Select offers a different reading. If younger buyers have become the majority, it is also because another category has vanished: the second-time buyers, owners who used to sell in order to buy larger. They are no longer selling, locked in by the credit terms they obtained before 2022. The market is being reshaped less by an arrival than by a withdrawal.

This issue untangles the three practical consequences of that shift for anyone looking in Paris: a scarcity of family homes, more technical negotiation on four- and five-room flats, sharper competition on two- and three-room ones. And a useful reminder: at €9,550/m², the capital remains the most expensive ticket in France.

The Paris market is holding up thanks to those who have stopped selling

Under-40s became the majority of Paris buyers in the third quarter of 2026. The statistic is accurate. The reading it is given is not always.

The figure comes from Century 21: 51.3% of flat buyers in Paris were under 40 in the third quarter of 2026, against 44.4% a year earlier. First-time buyers, over the same period, rose from 48.3% to 51.5% of acquirers. Two simultaneous shifts, suggesting a capital suddenly more accessible to a generation that had been priced out. The analysis is tempting. It is partial.

The real mechanism lies on the side of those absent. Settled Paris owners, those the profession calls second-time buyers, have largely stopped selling to buy again. Their immobility, as Charles Marinakis, president of Century 21, points out, is not down to the original purchase price but to the credit terms secured before 2022. A loan taken out at the time, at rates significantly lower, worked like an annuity; signing today at 3.55% over 20 years, according to the Meilleurtaux benchmark of 12 October 2026, weighs heavily on the monthly repayment for an equivalent property. The arithmetic no longer holds.

First consequence, visible on the ground: family homes are becoming scarcer. The four- and five-room flats, segments usually fed by couples selling to trade up, are reaching the market in smaller numbers. On these typologies, Home Select's hunters observe lengthening search times and more technical negotiation: less direct competition between buyers, but better-advised and less hurried sellers, who know their property will have few comparables.

Second consequence: the share of under-40s rises mechanically because buyers in their forties and fifties have withdrawn from the game. 51.3% of young buyers does not reflect a mass arrival, it is a vacuum being filled. The Banque de France data clarifies the shift: at the end of March 2026, first-time buyers made up 44.6% of mortgage production excluding renegotiations, against 38.7% for second-time buyers. First-timers became the majority because second-timers dropped out.

Third consequence, and the most concrete for anyone searching today: competition has concentrated on two- and three-room flats, where the 51.5% of first-time buyers are focused. On these surfaces, the Paris average of €9,550/m² (Notaires du Grand Paris, July 2026) has given up only 0.5% year on year. Demand absorbs the price easing, well-located and well-priced properties go fast, and the room for negotiation narrows as the pool of buyers thickens.

The Paris paradox comes down to two figures: flat transactions rose by 3.5% year on year in the Century 21 network in Paris, while they fell by 15.6% in the rest of the Île-de-France region. The capital holds up because a new buyer, often younger, replaces an absent seller. The Notaires du Grand Paris confirm the broader regional momentum: 36,810 transactions between May and July 2026, 5% more than a year earlier.

Home Select's reading is cautious. At €9,550/m², and with a price projected at €9,600/m² in October according to the Notaires du Grand Paris, speaking of a democratisation of the Paris market is an error of analysis. Charles Marinakis puts it bluntly: buying in Paris remains extremely difficult. What has changed is who buys, not what it costs. For a buyer, that means adapting one's strategy to the typology sought: negotiation on a five-room family flat does not obey the same levers as negotiation on a three-room flat on a mid-level floor.

Adapt your negotiation strategy to the property's typology

The temptation is strong to apply the same reasoning to every segment of the Paris market. It is a mistake, and the third quarter of 2026 makes that mistake costly. On a two- or three-room flat, where first-time buyers' demand concentrates (51.5% of flat buyers), a well-located and well-priced property will find several acquirers. Any offer more than 3 to 4% below the asking price risks being set aside. On a four- or five-room family flat, by contrast, the scarcity of supply has changed the rules: sellers are rare, better advised, less hurried. Room is found through time, not through tone.

Before any offer, put three questions to the vendor or to their agent: how long the property has been on the market, how many viewings it has received, and whether any offers have been turned down. Ask for the latest general meeting minutes, three years of service charges and the taxe foncière notice. On a family home that has been online for more than six weeks, negotiable room often reaches 5 to 7%; on a two-room flat fresh on the market, aim at the asking price and compete on speed of decision.

Finally, build the transfer duties into your real budget. Since the 2025 Finance Act and the City of Paris vote, non-first-time acquirers pay 6.32% in duties, against 5.81% for a first-time buyer. The 0.51 point gap represents around €2,000 on a €400,000 purchase, more above that: a line of negotiation in its own right if you are affected by the increase.
