Abstract As a result of the growing digitization of society and the development of electronic economy, current statistical data sources, including administrative registers, do not satisfy the information needs of society. Therefore, there are growing gaps in the statistical coverage of a number of sectors of the economy. One example of such a gap is the secondary real estate market, which is only partially accounted for by official statistical data sources. On the other hand new data sources such as the Internet or Big Data tend to decrease information gap in official statistics. The Web portals that specialise in brokerage on real estate market should be not neglected as a data source for statistics. Therefore, the aim of the paper is to use two Web portals devoted to the housing market to estimate supply measured in the number of flats offered to sale in Poznań, Poland. In addition, classification and quality of Web portals will be discussed.

Price Indexes

In the book, an attempt was made to catalogue knowledge concerning the importance of research into the dynamics of housing prices for social and economic development. The analysis of the experience of countries with well-developed real estate markets in the aspect of building price indexes was carried out. Based on original databases of asking and transaction prices, price indexes were built, which were then subjected to numerous resistance tests. The aims of these research tasks were as follows: 1) to examine the quality of offers for sale as a source of information about changes in the real estate market, 2) to find out whether the repeat sales method can be used for building price indexes and to critically assess this method in terms of the stability of the obtained results, 3) to analyze hedonic methods and indicate the preferred one in terms of the ratio of the quality of results to how time-consuming and cost-intensive it is to build such indexes, 4) to establish the importance of methods and sources of information for building price indexes in different time horizons, 5) to identify how important it is for the fluctuation of price indexes if the cooperative property right to a flat is not taken into account. In order to perform the research tasks and accomplish the goals scopes of the work were defined. The subject followed the aim of the study and refers to prices in the secondary housing market, encompassing both the property right and cooperative property right to a flat or house. The broad scope concerns the discussion in the general part, being narrowed down to the secondary market of flats located in multi-family and single-family buildings. The time scope covers the years 2000-2015, which is connected to the range of empirical studies carried out. They focused both on actual transactions and on offers of flats for sale. On this basis, we built databases which served as the starting point for further analyses. The study involved transactions and offers in the area of Poznan.

Real Estate Management

One of the main tasks of real estate management in the area of the municipality is making decisions concerning the location of investments on a local scale. These decisions should be taken with the principle of sustainable development. For such an action obliges Poland's membership in the European Union. Poland as a member of the EU is obliged to implement the rules in force in the Member States. Bearing in mind that any investment impact directly or indirectly on the economic development of the municipality, is therefore a significant impact on the local real estate market. Investments that have a negative impact on the environment can contribute to a reduction in the activity of the local real estate market. While performing tasks related to the economic development of the region and the increase in quality of life, increases the activity of the local real estate market. The work was carried out research on the dynamics of changes in the local real estate market in the area of the municipality Skrzyszow in the Malopolska province in Poland, in connection with the construction of the reservoir.

Ageing and Quality of Life - New Responses from the Real Estate Sector in Portugal (1) In the second half of the 20th century, the history of European demography is associated with a pronounced and widespread process of ageing. The 21st century will have to cater to the needs of an elderly population in transformation. Portugal is also part of this process and in efforts to improve the quality of life of the elderly, a wide range of facilities, services and social responses have been established by a variety of promoters, targeting several social levels. This paper will analyze a specific segment directed at an exclusive niche of the elderly population, the Senior Residential Condominiums. This is a very recent segment of the housing market, with high levels of comfort, quality, sanitation, health, and recreation, essential to full well-being. The paper intends to characterize this real estate market niche so as to identify its distinctive features, the promoting agents and how they can contribute to residents' quality of life.

Price Movements

Abstract The observation of price movements on the real estate market is an extremely difficult task as we have to face problems belonging to two spheres. The first of them is the specific nature of real estate as marketable objects and of the real estate market itself. The second one is the character and quality of data on real estate transaction prices. In this article the author, based on an empirical study, attempts to prove that even in a single segment of a local real estate market the prices in individual sub-segments can fluctuate with different intensity. The range of price movements can be so vast that it seems pointless to apply a single averaged price index for the whole segment, and usually that is what analysts do.

House Building

Having examined the building and decorating of the urban house, this chapter explores how the artisan approached marketing and selling real estate. As the first sustained analysis of property advertising in the eighteenth and early nineteenth-century Atlantic world, this chapter first considers how regional variations and social demographics (aristocratic audiences in London and Dublin compared with merchant audiences in Boston and Philadelphia) dictated the form and content of property notices, reflecting on issues such as location, quality of structural and decorative finish, convenience, and decorum. But while house-building and house-selling were principally economic activities, representing the motivating force for building mechanics to enter the real estate market, the evidence from property advertisements reveals that builders were cognizant of the semantics of advertising rhetoric and employed a vocabulary that emulated that of auctioneers, luxury goods manufacturers and other polite retailers.

Econometric Approach

There are situations in the real estate market in which a large number of properties have to be valued at the same time. In such cases it is advisable to use mass valuation methods. These methods involve estimating the value of a property on the basis of the values of the attributes defining it. The aim of the paper is to calibrate the influence of attributes on unit values of properties in mass appraisal in order to minimise the valuation error. The research was conducted for 318 residential properties located in Szczecin. The Szczecin Algorithm of Real Estate Mass Appraisal was used along with the econometric, statistical and expert approaches. The econometric approach is based on the ridge regression model, the statistical approach on the partial Kendall T correlation coefficients, and the expert approach on the AHP method. The quadratic programming was co-employed with the statistical and expert approaches in order to minimise the mean square error (MSE) of the valuations. The econometric and statistical approaches with the minimisation of the MSE generated best results. The least accurate results were obtained by means of the statistical and expert approaches without the minimisation of the MSE. However, even though the optimisation of the MSE improves the quality of valuations, it also narrows down their volatility, which might make the valuation of properties from the outside of a given database more problematic.

Periodic Fluctuations

Cycle fluctuations have been identified which includes real estate investment, real estate consumption, real estate industry and national economy. Spectral analysis is applied in such research based on the statistical data from 1997 to 2010 of Xi’an. The mutual relation could be found between investment and price of Xi’an real estate referring that investment increases with the rise in house prices. Furthermore, a great deal of randomness has been shown in Xi'an real estate consumption which does little effect on the cycle of real estate price indicating real estate market in Xi'an is a seller's market. At the same time, due to the fluctuation cycle of national economy in Xi’an is more than 12 years; the periodic fluctuations of national economy cannot be deduced from the periodic fluctuations of real estate in Xi’an.

Data Source

There are numerous approaches for integrating data from heterogeneous data sources. A common background assumption is that the data sources remain quite stable and are known in advance. Hence an integration system can be built to manipulate them. In practice there is, however, often a demand for supporting ad hoc information needs concerning unexpected autonomous data sources containing volatile data. A different approach is therefore needed. We propose that semantically similar data are harmonized when extracting data from XML-based data sources. We introduce a constructor algebra, which is a powerful tool in the harmonization of XML data. This algebra is able to form for any XML data source a unique relational representation, called an XML relation. We demonstrate that the XML relation representation supports grouping and aggregation of data needed, for example, in OLAP (online analytical processing) -style applications.

Purpose – The aim of the article is to identify the limitations and critical issues in the way information in the real estate sector in Italy is currently managed, and propose the principles of a method that would provide information and comparison of the phenomenon of over-supply and non-rational land use. This study is based on a series of assumptions, the first of which is a definition of “unsold”, deemed to mean “the amount of new housing units neither occupied nor sold nor rented”. In effect, unsold stock can be considered as over-supply of construction. Design/methodology/approach – The article identifies the critical aspects in the determination of unsold real estate in Italy, starting from the available data and research already carried out; the results are often contradictory. The comparison with programming systems of building production adopted in other countries allows identification of the guidelines that can be used to better understand and combat the phenomenon. Findings – The assessment of the state -of-the-art provides a clear picture of the shortcomings and potential of the tools used to date to meet the need of studying a complex phenomenon with many obscure points. Following the empirical analysis comes out a picture of inefficiencies due to the poor quality of information, as well as the reluctance of data-sharing and -integration procedures by the institutional and market players. Research limitations/implications – The research produces solutions addressed to the Italian situation, but it identifies systems and methods used in other countries. Practical implications – The article suggests the collection systems and management information that can be used for a more accurate knowledge of unsold real estate. Social implications – The article focuses on some of the limits of the Italian real estate market, highlighting the need for greater transparency and how this can contribute to a more conscious approach to the market. Originality/value – The article seeks to provide the necessary answers to those who must understand the reasons of harmful effects for the market, such as overproduction; besides some models focused on three areas – the procedures, the organization and the market – are also proposed.
