Purpose: The aim of the article is to present the affordability of rental prices in relation to property sales prices and to assess the situation in Poland compared to selected European Union countries. Design/methodology/approach: To examine rental affordability in Poland, the ratio of average rents to incomes was determined in the 7 largest cities, and compared. Rental prices for a standardized apartment size (50 m2 ) were calculated for selected EU capitals based on average rent per m2 rates, and their ratio to average monthly earnings of a full-time worker was assessed. Findings: Based on the conducted analyses, it can be concluded that despite the increase in average rents in the surveyed Polish cities, rental affordability is improving. This is due to the fact that incomes are rising faster than rental prices. Simultaneously, while rental costs in Poland burden budgets significantly, Warsaw's situation is not the worst among the selected European capitals. There are cities where high incomes do not guarantee ease of renting. Afforda is very limited, and housing expenses consume a significant portion of earnings (more than in Poland). Research limitations/implications: The analysis of rental affordability in Poland was conducted for the 7 largest cities. Further analysis for smaller cities would be valuable to assess affordability in smaller, local rental markets. In the context of the European market analysis, calculations were based on selected EU capitals due to data affordability regarding rental rates, making it difficult to generalize the situation across entire countries. These limitations suggest potential directions for further research focusing on both local markets within Poland and considering the situation across entire EU countries. Future research should also focus on developing new indicators and evaluation methods for housing affordability, as well as assessing the effectiveness of various housing policies. Practical implications: Determining rental affordability can provide crucial information for governments developing support programs for individuals struggling to afford rent, as well as for property owners and developers making decisions regarding new investments and property purchases for rental purposes based on investment returns. Knowledge of rental affordability can assist in adjusting market offerings and pricing strategies to meet market needs. Social implications: Studying rental affordability reveals the scale of issues related to mismatching rental prices with societal income levels. Affordable housing could increase societal mobility, enhancing income by providing access to better-paying jobs, education, and services. Affordable housing provides residents with a greater sense of stability, influencing quality of life and reducing stress. Originality/value: Rental affordability is a growing concern in the EU. While numerous indicators address this issue, most focus on the property sales market. The authors identified a gap in studying rental affordability, particularly in a European context. This research targets investors in the rental market, developers, and governments influencing rental rates. [ABSTRACT FROM AUTHOR]
