In the begining of the thesis, theoretical basis and definitions regarding rental housing and tenancy are presented. The main part of the thesis is composed of the market rent analysis results for rental apartments with a net floor area between 20 m2 and 200 m2 and residental buildings with net floor area of more than 50 m2.
