The thesis presents an analysis of apartments that were sold on free market, for the period between 1. 1. 2007 and 1. 6. 2015. Data was taken from the real estate register. Analyses of the annual transactions volume in Slovenia were realised for each year, as well as analyses by statistical regions and municipalities. Further on, we made a more detailed analysis of apartments sold in city municipalities. On the basis of representative transactions (transactions that met certain criteria) we analysed transactions volume, selling prices per square meter, selling prices of apartments, floor area and year of construction of the sold apartments. Finally, we compared the analysed parameters for all city municipalities together and discussed trends that are common to all city municipalities. Transactions volume in city municipalities represented almost 61 % of all apartment transactions in this period. Apartments sold in city municipality of Ljubljana represented around 46 % of all transaction volumes among city municipalities. In almost all city municipalites prices per square meter were the highest in the year 2008, and the lowest in the last two years of the analysed period. Selling prices of apartments between 2007 and 2015 fell for around 25 %. More than half of sold apartments were constructed in the sixties and the seventies.
