Chilly-Mazarin Property Prices, Rents & Rental Yields

About Chilly-Mazarin

Chilly-Mazarin is a city in Essonne department, France. That precise setting matters when reading apartment data: the figures describe this municipality, not the department as a whole. A location-specific view keeps the discussion anchored to what is measured here rather than to assumptions about neighbouring markets.

In October 2026, the clearest signal for apartments is that annual rents have fallen faster than annual sale prices. Average rent is down 22.7% year over year, while the average sale price is down 9.0% over the same period. Both movements point lower, but the gap between them is the central investment tension: cheaper acquisition prices do not, on their own, imply stronger income economics when the rental benchmark has moved further. Reading the two changes together is more informative than treating the purchase-price decline as a standalone opportunity.

The average apartment sale price stands at €191,000, while the reported yield is 6.03%. Those figures offer a current reference point, not a forecast or a guarantee of returns on an individual property. For an investor comparing apartment options, the useful question is how a specific asking price and achievable rent would relate to these citywide measures. The published yield gives context, but it should be considered alongside the uneven annual shifts in prices and rents, without assuming either trend will continue. October’s snapshot therefore calls for attention to the income side of the calculation as well as the purchase figure.
