The aim of my diploma thesis is to prepare documents for price calculation and determination of the common rent in the suburb of Brno - Žabovřesky. In this work, I used information from executed leases Realtors Matras&Matras & Real Estate Ltd. and Dvorak. Analysis of factors affecting price formation I have devoted the factors that I considered at that locality as valid for determining the price and verifying their influence on rental prices. I added my own factor into the monitored critical factors. This factor is noise. As the analysis results showed it was a major factor that significantly affects the final price of the lease. His inclusion among the decisive factors was correct. By setting standards and calculation of coefficients, I obtain results that helped determine the normal cost of rent and contributed to the view of the importance of determining the level of the individual factors to calculate the final rental price. Data collection, analysis and examination of the relationships between the key factors, I see as a guide for calculating the normal price, which will be used by districts and the real estate market.
