In this paper we investigate the driving factors associated with the Paris apartment market. We explore a database of around 276 000 transactions for residential properties in the Paris area over the 1982-2005 period. We develop a factorial model that may capture the systematic link between residential prices and a set of predefined economic variables or their linear combination. We measure this link by a multifactor approach which underlines the "true path" of the real estate market in the sense that systematic factors can represent it. The factors thus derived can be used to generate a "actor model" useful in comparison to existing price growth indices and that may provide valuable intuition for forecasting residential prices.
