The aim of this paper is to present and compare models that estimate the value of a property according to its characteristics. This information can be required by, for example, potential investors in the real estate markett. In this way, they will be able to compare the offer price of the property with the value obtained by the model, before making investment or disinvestment decisions. In this paper we apply supervised (regression tree, random forerst, nearest neighbour, SVM) and unsupervised (clustering) data analysis methods in order to estimate the value of dwellings located in the city of Madrid, Spain. It is found that the housing characteristic that most influences the price is the surface area, and to a lesser extent the number of rooms, whether the building has a lift, the number of bathrooms and whether the building has a car park. The best method of estimation, according to the MAPE, was the random forest method.

This article is based on the premise that it is possible to apply Henri Lefebvre’s critical-theoretical apparatus to complex urban processes as a pedagogical case study. From previous knowledge of Lefebvrian thought, the article provides an overview of what Lefebvre called “the science of the use of social space”, supported by a transdisciplinary methodological plurality. The starting point is that neoliberal social space is produced, prepared, and led to the imminent urban post-neoliberalism, in the midst of this movement, a sophisticated planning system appears, with the old promise of service tradition, egalitarian ethics and pragmatic orientation. But in practice, it only reproduces the impotence of being inside a wave of localized surplus-benefits that expels human residues, avoiding any reaction. The Lefebvrian apparatus and a part of its theoretical tradition guide the research on Barcelona as a paradigm of global real-estate violence. This urban phenomenon is examined in central Barcelona, in order to rescue it from the pessimism of its own inhabitants, from the harsh perception that urban centrality no longer reproduces life. In this way, the article puts into operation an analytical tool designed to sabotage the real-estate circuit through a renewed right to the production of radical social space.

AbstractAs toponymic means of inscribing urban space, street names have been addressed mainly by human geographers, who have articulated the field of critical place-name studies. In this paper, I continue the endeavor started in the previous issue published in Social Change Review of reading street names through sociological lenses. Whereas in the first part of this two-part contribution the analysis was made from functionalist and conflictualist perspectives, this second and final part employs social constructionism and the utilitarian theoretical tradition in making sociological sense of street nomenclatures. First, conceiving of street names as forming discursively constructed linguistic landscapes, the paper shows how urban namescapes – the “city-text” – are written, erased, and rewritten to reflect the shifting political powers. Second, the paper examines the neoliberal processes of place branding and toponymic commodification by which street names are turned into sought-after urban commodities with transactional value on the real estate market. The paper concludes by inviting sociologists to join the conversation on street names, which should become an important topic of sociological reflection.

One of the modern society priorities is the tendency towards sustainable social and economic development. Sustainable development is possible through the preservation and efficient use of the values created by our ancestors and the ability to meet current needs so as not to endanger the ability of future generations to meet their own needs. Real estate appraisal activity evaluates the changes in property value over time. Physical or legal actions on the property are justified only if the future value is not affected.Theory and practice of appraisal activity quantifies three approaches to value:The Sales Comparison Approach – value is examined in terms of current market preferences;The Income Approach – determine the income the property is expected to generate over time as a result of the most probable use;The Cost Approach – value is perceived in terms of replacement cost of real estate with one with comparable utility.Technical assessment of constructions is applied as a rule mainly in the cost approach, and has a major impact on the estimate of market value. The role of technical assessment is reduced, even ignored and not taken into account in other approaches.The present research examined the role of technical assessment of constructions in the process of real estate appraisal and the impact of inspection on the real estate value.

Purpose This paper aims to understand the paradoxal development in Buenos Aires, Argentina, where economic growth was not accompanied by improved housing access. The period between the years 2003 and 2013 was characterized by a sustained economic growth with social inclusion and a great expansion of both social and private housing supply in the cities of Argentina. However, this growth was not accompanied by an improvement in the overall access to land and housing. On the contrary, the habitation problems in terms of access to formal, environmentally safe and well-located land with decent facilities have worsened. The City of Buenos Aires is one of the places where this paradox is most manifested. Design/methodology/approach The functioning of the land markets and the real estate development in Buenos Aires will be analyzed in the period 2003-2013 in relation to the macroeconomic context, the monetary effort for the acquisition and rent of a formal dwelling and certain logics of urban development. Findings The rhythm of urban land valorization continuously surpassed that of other commodities and services. The expansion of residential production did not improve the access to formal housing. On the contrary, habitation issues have worsened and conflicts concerning access to land, housing and the city have rapidly increased since 2003. Originality/value In a Latin American context, this paper is the first to establish a conceptual relationship based on empirical data between land price dynamics and real estate development. The paper is also original in its identification of a change in valorization rhythm and pattern of real estate development in the past decade (2003-2013).

THE URBAN DISPERSION IN THE METROPOLITAN AREA OF BELÉM-PA: an analysis from the residential settlements on Mosqueiro IslandLA DISPERSIÓN URBANA EN EL ÁREA METROPOLITANA DE BELÉM-PA: un análisis de los asentamientos residenciales en la isla del MosqueiroRESUMOEste artigo tem como objetivo analisar a dispersão metropolitana de Belém, tendo como recorte empírico o distrito administrativo de Mosqueiro, espaço suburbano tradicionalmente utilizado como espaço de lazer. A Ilha de Mosqueiro, como também é conhecida, passa por importantes redefinições ligadas à influência metropolitana, sobretudo a partir da instalação de novos assentamentos residenciais. No presente trabalho, parte-se da ideia de que a dispersão metropolitana é produto e condição da reprodução das relações sociais de produção do capital em uma escala geográfica mais ampla, pois é na metrópole que se encontra boa parte das condições objetivas de realização do trabalho. Como resultados, entende-se que a dispersão da metrópole de Belém ocorre por razões outras que não se explicam, em princípio, apenas pela lógica formal de acumulação do capital imobiliário. Para tanto, o recorte espacial considerado é Mosqueiro que, embora faça parte da área de expansão do município de Belém, não foi afetado pela ação direta das empresas imobiliárias que atuam nos municípios da RMB e pelas políticas habitacionais do Estado, agentes responsáveis pela expansão da fronteira urbano-imobiliária. Há, portanto, uma expansão que ocorre por meio de formas não integralmente capitalistas de produção imobiliária.Palavras-chave: Dispersão Metropolita; Belém; Ilha de Mosqueiro.ABSTRACTThis article aims to analyze the metropolitan dispersion of Belém, having as empirical cut the administrative district of Mosqueiro, a suburban space traditionally used as leisure space. Mosqueiro Island, as it is also known, undergoes important redefinitions linked to the metropolitan influence, especially since the installation of new residential settlements. In the present work, one starts from the idea that the metropolitan dispersion is product and condition of the reproduction of the social relations of production of the capital in a wider geographic scale, since in the metropolis one finds a good part of the objective conditions of accomplishment of the work. As results, it is understood that the dispersion of the metropolis of Bethlehem occurs for other reasons that are not explained, in principle, only by the formal logic of accumulation of real estate capital. To do so, the spatial reduction considered is Mosqueiro, which, although it is part of the expansion area of the city of Belém, was not affected by the direct action of the real estate companies operating in the municipalities of the RMB and by the housing policies of the State, agents responsible for the expansion of urban-real estate frontier. There is, therefore, an expansion that takes place through non-integrally capitalist forms of real estate production.Keywords: Metropolitan Dispersion; Belém; Mosqueiro Island.RESUMENEste artículo tiene como objetivo analizar la dispersión metropolitana de Belém, teniendo como recorte empírico el distrito administrativo de Mosqueiro, espacio suburbano tradicionalmente utilizado como espacio de ocio.
