This article deals with the issue of the influence of brownfields on the price and value of the given properties in the municipality of Detmarovice. These municipalities are located in the Moravian-Silesian region. There are 180 abandoned complexes and facilities in the mentioned region. There are 11 brownfields in the village that were previously used primarily for industrial activities. The purpose of this article is to determine whether brownfields affect the price or value of real estate in Detmarovice in some way. In the framework of this article, marketing research was developed, where a structured questionnaire was created. Respondents were asked to comment on their views, factors, and characteristics of brownfields that are of key importance in terms of their negative impact on property prices. Marketing research ran from autumn 2016 to spring 2017. The research focused on the views of respondents and their more detailed segmentation. According to the findings, most of the populations did not want to live in the vicinity of the brownfield. In addition, the addressed residents did not buy property that is located near the abandoned real estate. Subsequently, it was found that among the most serious reasons why brownfields reduce value or price is the occurrence of pathological phenomena and dangerous from the point of view of the construction-technical conditions.
