Technical progress makes humanity create new technologies and methods in all spheres of life. Evaluation of property also in there. In current moment there are several methods, which are badly obsolete. For example, there are some cases, when building in decrepit or emergency condition were able to buy in cost several times higher than objective cost. These cases aren't unique. New method of evaluation of property could possibly help if not to stop in all appearing of this cases but less their amount. New method is based on Building Information Model (BIM). This model allow take all needed information about building in the currnet moment of time and see in dynamic, how change different indicators of building. This system can be more useful if it associates some amount of building, which differs indicators of interest building and reflecting effects of that building on themselves. This technology can be looked as Extented BIM. Consideration of implementing BIM in evaluation of property has very perspective vay - this can accelerate the time building can be evaluated, and also it let potential client to see all information about building which he need. This makes process of purchase-sale of property more clear, which, by turn, help avoid conflicts when property being researched before purchasing.
