The Cyclical relevance of the valorisation of the real estate per square meter price indicator

The valorisation of real estate by the using of price per square meter presents known risks but conserves the advantage of a rapid publication. Its approximate character is mainly linked to the insufficiency of the explanatory part of the surface in the price. However, this part seems fluctuate with the cycle of the real estate, so that relevance of this method would be oscillatory. We try to test this assumption by using a new data base which is applied to the case of Bordeaux city between 1985 and 2005.
