COMPASS Kalstone Paris Residential Property Index



A disruptive index on the real estate market

The COMPASS Kalstone Paris Residential Property Index (PARISSQM Index) measures the “typical” price in euro per square meter of residential properties transacted in Paris, over a period of two weeks.

PNS is considered as the most exhaustive source of information related to real estate transactions in Paris.

The PARISSQM is published every two weeks on Friday evening at 5:30pm Paris Time. It is quoted in Euros per square meter and aims to become the benchmark for the “typical” transacted price per square meter  of Paris residential properties.
