Two repeat sales indices are estimated for the Paris and close surrounding area : a Case & Shiller (1987) Weighted Repeat Sales (WRS) index and a Factorial index. We compare them to different existing indices: (i) the square metre index provided by the Chambre des Notaires de Paris and INSEE, (ii) the IPD indices, (iii) the listed real estate index. Our conclusions yield interesting implications concerning real estate risk and suggest the construction of jointly using the repeat sales and the factorial approaches.
