The paper proposes a solution to the problem of how to introduce non- -measurable features (attributes) of a property that significantly affect its value to the process of its valuation. The authors adopt two measures enabling them to study the influence of order features on the value of property, the Spearman rank coefficients and standardized ßk coefficients, and proceed to check their efficiency, applying an algorithm of mass property valuation (SAMWN) to the sample of 567 plots of land in Szczecin designated for housing purposes. The results thus obtained are then compared with the valuations of these plots of land performed by property appraisers. The study demonstrates that lower valuation errors are obtained when using standardized ßk coefficients than the Spearman rank coefficients.

AbstractThe importance of both income rank and relative income, as indicators of status, has long been recognised in the literature on life satisfaction and happiness. Recently, several authors have made explicit comparisons of the relative importance of these two measures of income status, and concluded that rank dominates to the extent that reference income becomes insignificant in regressions including both these explanatory variables, and that even absolute or household income, otherwise always positively related to happiness, may lose statistical significance. Here we test this hypothesis with a large UK panel (British Household Panel Survey and Understanding Society) for 1996–2017, split by age and retirement status, and find, contrary to previous results, that rank, household income and reference income are all usually important explanatory variables, but with significant differences between subgroups. This finding holds when rank is in its often-used relative form, and also with absolute rank.

Purpose This study aims to present a problem of noise compensation related to the localization of single-family houses in the restricted use areas (RUA) created around airports. The authors presented different methodological approaches to the valuation of such amends and characterized distinct solutions applied in that area in chosen countries and cities. Design/methodology/approach To estimate the level of those indemnities, linear models including spatial and generalized linear models, were applied. The set of explanatory variables contains quantitative and qualitative attributes of real estates. The influence of outliers indicated by means of cluster analysis on the received results were also considered. Findings The results show that after accounting for noise level and house characteristics, houses in noisier areas were sold for less than houses subjected to less noise. Unit prices of houses located outside the RUA were on average 17.05 per cent higher than the prices observed in zone with noise level for the daytime of 60 dB and 8.95 per cent in zone characterized by noise level for the daytime of 55 dB. Practical implications Received results can be compared with results obtained by other authors, but its most important application is possibility of use the proposed methodology by judicial appraisers to assess the proper level of noise compensation for home owners or tenants. Originality/value An identification of real estate market heterogeneity and its considering in estimation of compensation related to airport noise evidence some novelty of the research.

Purpose The approved methodology of property valuation in Albania evaluates the reference property prices based on the average contractual price of properties sold and takes into account only factors such as price, square meters of living and location of property. Simple method is the one used on evaluating the reference price for a group of properties with similar characteristics. The purpose of this study is, by building a hedonistic pricing model for apartments in Tirana, to prove empirically that in addition to location, there are other characteristics that affect the value of apartments. Design/methodology/approach The capital city is chosen as a case study for the construction of a hedonistic pricing model. In the database were included detailed characteristics of 1,421 apartments. Multiple regression analysis was chosen in this model as a method to test hypotheses about the causal relationship between house value Y and independent variables XS, representing the characteristics of the property. Population equation parameters β0, β1, β2 […], βn. were evaluated by the ordinary least squares method. Selection of α-standard is 5 per cent, taking into account the significant number of observations and the degree of regression freedom. Findings Based on this study, it was proved empirically that the characteristics of the apartments as square meters of living, number of rooms, access to parking, furniture, view and surface of living affect their price. As a literature review showed, location is the most important variable that affects the value. Results showed that the marginal effect that the number of rooms has on the apartment value depends on the square meters of living of the apartment. In the same line, the effect of the square meters of living on value depends on the square meters, as the relationship between these variables is nonlinear and depends more on the number of rooms. Research limitations/implications It was impossible to find the information on property sales contracts. That is why this study was oriented toward the market and took into account the properties offered for sale at one of the biggest real estate agency “Çelësi”. More accurate information regarding properties characteristics could be obtained. The information was limited and depended on the best apartment characteristics that potential sellers wanted to advertise. On the other side, contractual sales price is oriented by the reference price, so, the applied methodology has resulted in better evaluations of real estate prices, which reflect the market price. Practical implications This study is conducted as an applicable research. After analyzing the property valuation system in Albania, the study recommends the change of the method used on apartment valuation. Improvement of the property valuation system requires first of all creation of a complete and updated database for all real estate sales. Social implications Property valuation is a very important function of the land administration system which directly affects people’s life. Property evaluation for different purposes like tax evaluation, compensation and expropriation is a process that must be designed using an equal, transparent and well-accepted methodology by all. Promotion of property valuation system development is helpful to various interest groups in society, as it can reduce the risk of investment in this sector and encourages lower rates of interest on loans. Originality/value To the author's knowledge, the hedonic model is not applied on the Albanian housing market, thus providing encouragement to deepen the study in this regard. The study is original and has a very important impact on policymakers to change the actual property valuation methodology to obtain more accurate property values.

AbstractResearch background: Mass appraisal is a process in which multiple properties are appraised simultaneously, with a uniform approach. One of the tools that can be used in this area are multiple regression models. In the valuation of real estate features are often described on an ordinal or nominal scale. Replacing them with dummy variables with an insufficient number of observations leads to multicollinearity. On the other hand, there is a risk of overfitting the model. One of the ways to eliminate or weaken these phenomena is to introduce regularization based on a model’s penalization for the high values of its weights.Purpose: The aim of the study is to verify the hypothesis whether regularized regression reduces the errors of property valuation and which of the analyzed methods is the most effective in this context.Research methodology: The article will present a study in which two ways of regularization will be applied – ridge and lasso regression, in the context of their impact on the errors of property valuation. The analyzed data set includes over 300 land properties valued by property appraisers. The key aspects of the study are the selection of optimal values of the regularization parameter and its influence on model’s errors with a different number of observations in the training sets.Results: The study showed that regularization improves valuation results and, more specifically, allows for lower average absolute percentage errors. The improvement of model effectiveness was more pronounced in the case of ridge regression. An important result is also that regularization has provided a higher accuracy of valuation compared to multiple regression models for smaller training sets.Novelty: The article confirms the effectiveness of regularization as a way to eliminate the problem of multicollinearity or overfitting of the model. The results showed that ridge regression can be an effective way of modelling the value of real estate. Especially in the case of a small amount of market data, which is an important conclusion in the context of the real estate market.

Annotation. Introduction. One of the trends in the development of the modern real estate market in Ukraine is the gradual growth of the real estate owners, and, accordingly, the change of the real estate management system, in particular, in the field of municipal management. Real estate, as a strategic asset, needs to be managed at a professional level. Therefore, the mechanism of property valuation of territorial communities is perceived as one of the tools of effective property management. Purpose. The purpose of this article is to find and scientifically substantiate the priority areas for improving the effectiveness of property valuation of territorial communities, and analysis related to the mechanism of evaluation of management aspects – goals, approaches, methods and characteristics. Results. The article analyzes the essence of effective management of municipal property – focuses on management goals, the priority of which is the creation of conditions for normal activities, both for each resident and all in general, analyzes the process of determining the effectiveness of municipal management in various fields and its characteristics, methods of evaluating the effectiveness of management. The main provision that guides real estate activities is that real estate development projects should meet the needs of consumers as much as possible. The views of domestic researcher N. Smentina on approaches to assessing the effectiveness of communal property – economic and social. The article provides a detailed substantive analysis of the concept of “real estate” within the complex development and its spatio-temporal characteristics that affect its value. The importance of the characteristic “optimal use of real estate” is determined. The “optimal use of real estate” reveals the conceptual content of the process of assessing the effectiveness of property use. Conclusions. Summing up, property valuation is especially important in the context of increasing the economic benefits from the sale of communal property, but the mechanism of property valuation of territorial communities in Ukrainian legislation still does not determine some specific aspects of municipal property valuation.. Keywords: property; property management; management efficiency; territorial community.

Abstract The real estate market is a domain of multi-faceted contemplations - ranging from economical, societal and sociological, to juridical aspects. These domains are important because they create an area of real estate (internal and external) and have an impact on the real estate market. The multifariousness of properties has an influence on the creation of market values. Investors and people whose jobs are connected with the real estate market describe it using points, variables and characteristic attributes and on their basis, create algorithms or real estate market models. We need to draw attention to the fact that, in most cases, the terms “features “, “variables”, and “attributes” are treated as the same. The authors of the present article do not agree with that kind of approach and would like to systematize the knowledge in this area. The goal of the article is to explain problematic terms, and indicate their genesis and sense of using them. The paper compares the legal systems of property valuation in three different countries. It describes their different valuation procedures and provides commentary on them.
