The authors consider the interconnection of the concepts "environmental factors of life quality" - "health saving" - " property value " (as the boundaries of human life activity, aimed at health saving taking into account the environmental risks) using the example of Moscow. The issue of the environmental component in the assessment of real estate and the environment is one of the most discussed at the moment. The authors concluded that today’s methods used to estimate the value of residential properties in Moscow almost don’t reflect the level of ecological cleanliness of the districts and, as a consequence, the level of health saving of the population living there. The methodology for assessing the property value should be based, inter alia, on a system of health-saving indicators, including: environmental performance (sanitary and hygienic), social indicators and lifestyle.
