Like her older sister, Louise Anne, she owned much land and many private residences outside of the capital. In 1734, she bought the Hôtel de Noirmoutier on the rue de Grenelles in Paris. She also bought much land surrounding the hôtel and considerably enlarged the property. In 1744, she bought the estates and lordships of Villegénis and Igny. She remodelled the Château de Villegénis in 1755. The cost of the remodelling was 430,000 livres. To raise that sum, she sold the estate and seigneurie of Vallery, the traditional burial place of the Condé family, to M. and Mme. de Launay, for 280,000 livres. François Desportes, painter of the king's hunts, supplied large canvases for the appartements.
