The following paper presents the results of a housing community clustering research that has been carried out in Olsztyn city. The clustering procedure was realized with the use of the SOFM (self-organizing feature maps) method. The method required particular property features application. These involved: commune share in a housing community, location, land management, condition of the buildings. Having learned and verified the tool a two dimension topological map was made that organized the researched object into eight homogeneous groups. On the basis of the maps and classifying data detailed analysis and cluster synthesis of the given results has been made. The results show that in most of the housing community properties that the Olsztyn commune had a share in, moste of the communes’ shares significantly decreased and the process of scattered privatization was concentrated among properties that had good location and a big need of renovation. The clustered objects differed in terms of their location (general and detailed) and at most medium technical condition. The learned tool is capable of object assessment that has not been presented during the process of learning. The adopted method occurred to be much more effective than the k-average method because if has given much more internally homogenous clusters of the objects. Moreover the given clusters were more transparent and useful in terms of the assumed aim of clustering.

In the paper general issues concerning the payment of the lease rent is presented. Negotiating conditions of the lease agreement has the direct effect to the economic situation of the real estate, especially with reference to such elements of the lease agreement as: the period, the rate of the rent and principles of restoring. Authors presented the advantages and disadvantages of individual elements of the lease agreement which have the significant effect to its contents, methods of calculating rents and ways of valorization of the amount of rates of the rent. With a view to taking the rational decision as for conditions of the conclusion of a lease agreement an acquaintance of her current value is necessary. The changeability causes discounted cash flows, that the nominal value of the lease agreement is usually different from an current value. In connection with the above, one should effect calculations being aimed at determining the current value of the lease agreement – to this purpose authors presented the example, exploiting the NPV function for this purpose.

The paper deals with differences in space management within new built gated communities in Toruń. There were also signalized preliminary suggestions about appropriate way of planning of new gated communities. All gated communities are attached from public space. Depending on way of space planning and management there can arise neighbourhood communities (proper way of planning) or social conflicts (wrong way of planning).

The calculation of new gruop of indicators – EWIT (economical land revelance indicators) allowed fix of model indicators, which could be use in practice for calculating initial value of land on investigated area. EWIT indicators because of the possibility of their practical application had to be carefully examined in the light of correlation with the prices of constructional and agricultural land. There was identified –EWIT(RE) indicator that can be used to calculate the initial value of the parcel. The choice of these indicators indicate that in the investigated area increasing of price of building land is in line with the trend of increasing of attractiveness value of recreation and tourism, but not in direct way whereas as lack of agricultural values, and thus the weight of indicators adopted for the (RE) are the most useful practical as well-defined set of characteristics that need to be transformed in order to increase the attractiveness of the area.

In this paper we determined the distribution function of unit land prices of undeveloped land. The analysis was based on 1752 sale transactions in Kraków. We found that the data follows the log-normal distribution with very high significance level. The result obtained suggests that the distribution function of the unit land prices is the same as that of small and middle ranges of society wealth.

Spatial management is the interdisciplinary field of the humans being activities in space, which is mainly connected with spatial planning, valuation of real property, management of property. To make these activities more effective, they must be based on a number of information which is derived from many sources. One of these sources, that is considered as the fundamental one, is cadastre. There are two types of data in cadastre – spatial and descriptive one. Approaching to the optimal development of the land will bring the expected results, only if in the definite practical activities, there is usage of the selected set of the cadastral data of the high quality. Defining such a set of data is possible after determining, based on results of analysis of low regulations of activities connected with spatial management, the table of the priorities of the demand for the definite kinds of the cadastral data. The fact of use of the cadastral data in different tasks of human activities in the space, brings on the need of defining the multitasks of the cadastral data in spatial management. This goal could be achieved by taking the established priorities into consideration. Quality of cadastral datasets used in the realization of the tasks connected with spatial management should be evaluated by persons connected professionally with spatial planning and management. In order to achieve the assumed aim of the study 67,experts’ opinions have been used and the results of the study have been processed with the use of the scoring-based evaluation method. The study has shown that, from the point of view of the spatial management, the most desired kinds of data are: the cadastral reference number of the parcel/lot, its area, the information about the owner, descriptive data included in the cadastral records. Among all the studied documents, the quality of the cadastral map has been assessed best by the experts.
