Confidence: high.

Better served than 7 % of the 12,699 communes of a similar size.

Compare this with communes of a similar size. The score measures how well a place is served relative to its own size band, and larger communes score higher as a rule — so it reads meaningfully against another village, and misleadingly against a town.

80 houses sold between 2021 and 2025, at a median of 398,650 € — 3,473 € per m² of built surface. ^[13]

17 flats sold over the same window, at a median of 210,000 € — 3,466 € per m². ^[13]

The median across Yvelines is 3,657 € per m², so this commune sits about level with it. ^[13]

These are recorded sale prices, not valuations or asking prices, and a median over five years spans five different markets. Built surface excludes land, which carries much of a rural property's value.
