Tourism is undeniably an essential sector on the island of Korčula and plays a vital role in the local economy. However, the growth of tourism on the island brings specific challenges and impacts on the resident population, especially housing affordability. It is essential to investigate how the inhabitants of the island of Korčula perceive the effects of tourism on real estate prices, what benefits tourism can bring to the resident population, and what kind of view they have on the development of tourism in the context of quality of life. The increase in the number of foreign tourists during the summer season directly impacts the real estate market on the islands, including the island of Korčula. The increased demand for land in the limited area of the island results in an increase in real estate prices and a higher number of transactions. This rise in real estate prices has a negative impact on housing affordability for the local population. It is significantly more difficult for residents to become owners of apartments or apartments than for people living in Croatia without tourist activity. To cope with these challenges, in recent years, the domicile population of the island of Korčula has found an opportunity to earn money by renting out their own real estate, such as apartments, apartments, or family houses. This leads to an increase in the number of renters among the local population. Rental properties can provide an additional source of income and economic benefit for domiciled residents.

It is essential to focus on preserving the balance between tourism development and the needs of local communities. Sustainable tourism can provide long-term benefits, such as increased employment, infrastructure investment, and cultural identity preservation, which will further improve the quality of life of the resident population. Therefore, to understand the impact of tourism on the domicile population of the island of Korčula, it is necessary to conduct thorough research that will include an assessment of economic and sociocultural aspects. Only in this way can we get a complete picture of how tourism can affect housing affordability, what benefits it can bring to the local population, and how to ensure that tourism contributes to sustainable development and improved quality of life on the island of Korčula.
