The empirical part of the research shows that econometric models appear to have significant potential on the basis of the estimated valuation of dwellings. Therefore econometric models can support effectiveness of companies activity in real estate market and mortgage market. There is a good idea to say - that in the majority cases the more standard measured object is, the most narrowly this type of estimate is. It has been mentioned that the precision of modelling decreased because of the recession in real estate market. Of course, building a model requires access to relevant databases, but let us to identify the group of vital factors that determines the real market value of dwellings. Moreover when it comes to the question of stochastic aspects of valuation, econometric and statistic modelling seems to be terribly important.
