Q. Does one recite a Sheheyanu when buying a dwelling such as a house or a condo?

A. Shulchan Aruch (O.H. 223: 3) rules that if one builds a new house recites Shecheheyanu. Mishna Berura mentions that if it is a property shared by other family members the blessing is Hatov Vehametiv. He writes also that the same applies if the property is not a new building
