Comparative approach allows to specify the value of the real estate on the assumption that the value of the appraised real estate is equal to the price obtained for similar real estates in the course of market transactions, corrected with regard to the features which differentiate these properties and taking into consideration the changes of price levels in time.

In the statistical market analysis method, the basis for comparison is a representative sample of real estates on the local market in the period when price research was conducted. In that case, the market value is a correction of the average calculated on the basis of the collection of all prices or based on representative sample.
