The real estate market has been one of the core pillars of the Spanish economy for decades. Other than providing homes and houses to live, offices to work, and retail centers to shop, it has been a potent investment market as well. In fact, there is more money being invested in the Spanish real estate market than in the French one, with Spanish projections being around 20 billion and French ones being around 15 billion euros (Lima, 2026) (Norman et al., 2026). At the same time, the real estate market is approximately 2.5 times smaller than the entire agricultural industry in Spain, which totalled approximately 52 billion euros in 2025 (Mehta, 2026). This indicates the size and the share in the Spanish economy that real estate has obtained over the years. Given that the Spanish real estate market has grown from slightly over 2 billion euros in 2000 to projections of 20 billion euros in 2026 (Lima, 2026) (Savills Research Spain, 2026), this provides an opportunity to review what factors have spurred the growth and development of the Spanish real estate market over this period of time. With an understanding of the trends and overall developments of the Spanish real estate market over the last 25 years, including projections of the year 2026, investors can learn from history and make based predictions about how the markets are likely to behave in the future. It is particularly interesting to review the developments in the real estate market given the introduction of the euro in 1999 (Martín et al., 2019), the Global Financial Crisis of 2008 (Baudino et al., 2023), and the COVID-19 pandemic (Goryunov et al., 2026).

In order to be able to actually get to an understanding of the real estate market trends and dynamics, there are several important elements to explain throughout the discussion. Those are (1) external factors (Shi, 2025) (Goryunov et al., 2023), such as the the introduction of the euro in 1999 or the occurrence of the COVID-19 pandemic in 2020, (2) macroeconomic factors (Pyhrr et al., 1999), such as the national GDP, inflation rates, and interest rates, (3) microeconomic factors or sectoral drivers (Nordby, 2022), such as rent rates, vacancy rates, and capitalization rates, and finally (4) the performance and importance of different real estate submarkets within the country, both per property typology as per geographical location (Savills Research Spain, 2026). Understanding the relationships between all these factors is required if one wants to make an accurate forecast about future developments.

There are several relevant developments within the real estate sector that warrant an investigation into the trends and dynamics that govern the sector itself. Firstly, there are the real estate market dynamics that are changing rapidly since the COVID-19 pandemic. As will be discussed later in this report, the pandemic has created significant shifts in investment strategies. Not only do people work more from home, but also several market segments are viewed differently, influencing the investment decisions and property performances. Secondly, also somewhat linked to the pandemic, is the increasing diversification within the real estate market. Not only are there more available property types to invest in, there are also stronger secondary locations that attract more investment capital. Both developments increase the diversification, and this research attempts to discern the causes and effects of this diversification. The geographical diversification also relates to the third point, which is the dynamics between urban areas and the national average. National tendencies can give a good insight into the functioning of the overall real estate market, but specific urban areas or provinces can have different trends and instigators than the national average indicates. The distinction between national and regional tendencies, as is visible in the cases of Madrid, Barcelona, and the Spanish average, tend to perform differently when looking at the aforementioned elements in explaining real estate investment behaviour. Lastly, tying into the regional dynamics and important elements are the volatile macroeconomic factors. Especially inflation and interest rates have been varying significantly over the last decade, creating a new investment environment with every change. Understanding their workings and relations to investment volumes and allocations can prove very valuable in trying to forecast trends and dynamics within real estate.

All dynamics and trends that are visible since 2000 are related to either one of the relevant factors or antecedents. From the introduction of the euro to the COVID-19 pandemic and the subsequent volatile macroeconomic factors, everything can be related to one another through a chain of cause and effect. Even though in hindsight, everything is more easily explained than in the moment itself, recognising and understanding the cause-and-effect relationships of how macroeconomic factors interact with microeconomic factors. Subsequently, how both these types of factors dictate total investment volumes and its allocations across submarkets can show patterns that should hold true for future reference.

This research does not provide intrinsically new insights. Rather, it combines many reports, findings, and theories about the Spanish real estate market over the last 25 years and combines them into a coherent overview of all relevant factors. The thesis thus attempts to create a clear and understandable overview of how all elements interact not only with each other, but also their effects over the longer term. In order to provide a clear structure of this thesis, the research has been organised in the following order. Firstly, there will be a revision and discussion of the relevant literature regarding most of the important themes presented in this thesis. Secondly, there will be a chapter on the methodology used in order to be able to arrive at the wanted result of the investigation. The third chapter will show the formulation of the research hypothesis, research questions, and research objectives. Subsequently, the fourth part will include the results and discussion of the data. This chapter will, as mentioned, include the discussion of the workings of the external factors, macroeconomic factors, microeconomic factors, and volume allocation per property typology and geographical location, and their effects on one another. Fifthly, there will be a conclusion, where the main findings will be summarised and the research questions will be answered concisely but accurately. Also, research limitations and future research suggestions will be outlined here. Lastly, there is a chapter on the sustainable and ethical contributions of this thesis to the real estate industry, called the memorandum. These considerations go beyond solely environmental sustainability and morality, but will include a discussion about economic sustainability and ethics through transparency and fairness. Following the memorandum will be the bibliography of all sources utilised in the research of this thesis, the annexes used, and the footnotes used in this thesis, in the cases of having excerpts from sources in other languages than English.
