The authenticated deeds include estates’ transaction prices for the groups of estates or estates with complicated structure. Prices obtained from authenticated deeds neither can be used for market analysis, nor for similar estates’ value estimation. The need for the whole estate’s price separation into unit transaction prices appears then. Finding solution for this problem enables using information from authenticated deeds in the estates market analysis. It also helps in applying this data into similar estates’ cadastral and market value estimation. The model of estate’s transaction price (from authenticated deed) dividing into particular elements’ prices is presented in this paper. Number of transactions is often smaller then deliberated estate’s elements number, so the conditional estates’ unit prices model should be used for estimation. The deliberated real estates are grouped according to its destination in the local spatial plan, building type and the building exploitation method. The conditional equations should be set to separate the whole transaction price into elements’ prices, for every group of similar estates. The unit prices’ conditional model gives proper market solutions if unit prices’ approximations adequate for the analyzed market are predetermined. Markets differing on localization may be characterized by various real estates’ unit element prices. The unit prices proportion ratios may be the reference for various estates markets.
