Redefining House Valuation: Methodologically Merging People’s Preferences & Opinions Ref.No.SSTCRC2675
1. Introduction
In this project, we aim to transform house valuation by focusing on people's preferences and opinions, making the process more aligned with individual and community values. In housing, preferences reveal what people like more, guiding them to choose one option over another. For instance, a family might prefer a house with a big backyard, while a young professional might choose a smaller apartment close to public transit. Opinions, on the other hand, are personal views or judgments about properties that aren't always based on facts. For example, someone might think a house with a modern design is more appealing, even if it's not as spacious, or they might favor a neighborhood because they’ve heard it's prestigious, despite the actual amenities available. So, as we see, preferences typically reflect practical considerations and personal priorities that influence decisionmaking, especially in housing market. However, opinions often reflect subjective perceptions and beliefs rather than objective criteria. Accordingly, preferences influence housing choices by highlighting practical needs and priorities, while opinions affect perceptions of property value based on subjective judgments or limited information. Thus, preferences tend to stay consistent, and because of this, they can set general trends in the housing market. They lead people to choose certain options, and by understanding these preferences through evaluation methods, planners can better prioritize and shape housing features. While many factors (maybe we call, “behind considerations” as people’s opinions) influence preferences, they are often ignored in valuation methods because opinions are not fixed and can frequently change. This unpredictability makes them less reliable for decision-making. As a result, valuation methods typically focus on more stable factors (preferences), like the size of house (Physical features), and may not give much weight to intermediate factors such as opinions. As respects, opinions can provide useful insights, especially when exploring consumer preferences and shifts in the market by using valuation methods. Opinions can be considered alongside preferences to give a clearer picture of housing market change.
There are several ways to figure out what people value in the housing market. Common methods include the Hedonic Pricing Method (hereafter HPM), the Choice Experiment Method (hereafter CEM), and the Conditional Valuation Method (hereafter CVM). These approaches use statistical models to reveal consumer preferences, but it’s important to note that these preferences might not always align with people's opinions or subjective views on housing choices. In this research, we aim to develop a model that looks at both the market and non-market values of urban housing. We want to understand what makes a residential unit valuable beyond just its structural features that can be sold on the market. By connecting these two types of values, we hope to create a more comprehensive understanding of how urban housing is valued. It is important to note that even when considering non-market values (in the mentioned methods), structural features still play a significant role in determining the overall value of a property. This issue is so clear that even real estate consultants, for example, have come up with equations that take into account factors such as location, age, and size of a property to determine its market price. Other features, such as lighting, proximity to noisy areas or metro stations may be used as selling points in advertisements, but do not necessarily contribute to the market value of the property. So, the bottom line here is that the economic methods we use to figure out the market & non market values of housing tend to focus heavily on physical and structural preferences. We need to take a step back and rethink these methods to make sure we're also considering people's opinions. We should come up with new and improved models to help people choose the right place to call home. While housing has become more of a capital good in many countries (such as Iran), we shouldn't forget about the importance of maintaining high-quality living spaces and creating good places for living. Even though researchers may provide a checklist of features that are valued in homes, these tend to lean towards structural elements that can be easily quantified. This can lead to a situation where investors and developers prioritize these specific features and end up overlooking other important aspects that make a house feel like a home.
2. Research Progress
To date, a preliminary review of both international and Persian literature has been conducted, including review studies as well as empirical research on housing valuation, residential preferences, and non-market valuation approaches. This review has enabled the identification of an important research gap: while existing valuation methods, particularly Hedonic Pricing Models, are highly effective in capturing structural and observable housing attributes, they provide limited insight into the role of residents’ opinions, perceptions, and subjective evaluations. Even methods designed to elicit preferences, such as Choice Experiments, often constrain respondents to predefined attributes and may therefore overlook broader opinion-based dimensions of housing value.
Building on insights from the reviewed literature and our previous work in this field, a preliminary conceptual proposition has been developed that seeks to bridge the gap between preferences and opinions in housing valuation. However, further work is needed to refine this proposition and translate it into a robust analytical framework.
The next stage of the project will involve a collaborative and systematic synthesis of the reviewed literature to develop a stronger conceptual and methodological foundation. Through interdisciplinary discussion and joint analysis, the research team will work toward identifying key dimensions of housing value that are currently underrepresented in existing valuation frameworks and explore alternative approaches for integrating them into housing assessment models.
A further objective is to conduct comparative case studies across different cities and countries through collaboration with researchers from diverse geographical contexts. Such comparisons will help evaluate whether structural attributes continue to dominate housing valuation across different housing markets and cultural settings, or whether opinion-based and perception-based factors play a greater role than currently reflected in conventional valuation models. Findings from these comparative studies will contribute to the development of a more comprehensive and transferable framework for housing valuation that incorporates both market-oriented preferences and subjective residential evaluations.
3. Required Cooperation
·Literature synthesis and conceptual framework development
·Comparative case study design and implementation across different cities and countries
·Data collection (surveys, interviews, and housing market data)
·Data processing and statistical analysis
·Integration of qualitative and quantitative research methods
·Expertise in housing valuation, residential preferences, and non-market valuation approaches
·Cross-cultural and cross-national comparative analysis

4. Benefits
The project will contribute to the development of a more comprehensive housing valuation framework that integrates both market-based preferences and residents’ subjective opinions and perceptions. By identifying dimensions of housing value that are overlooked in conventional valuation methods, the research will advance theoretical and methodological understanding of housing assessment. The comparative findings across different cities and countries will provide insights into the relative importance of structural, preference-based, and opinion-based factors in diverse housing markets and cultural contexts. Ultimately, the project can support policymakers, urban planners, and housing professionals in designing more people-centered housing policies, valuation practices, and residential development strategies.
