North Chungcheong is Korea's only landlocked province, sitting at the geographic center of the country. What it lacks in coastline it makes up for in mountains, lakes, and forests. The Sobaek mountain range runs through the eastern half, and Chungju Lake — one of Korea's largest — anchors the region's outdoor tourism.

Cheongju, the provincial capital, is a modern city with an international airport (CJJ) that serves budget airlines to Japan, China, and Southeast Asia. From most properties in the province, you're 50 minutes to Cheongju and under 2 hours to Seoul by car or KTX.

The central location is the region's secret weapon for STR investors. Properties here can attract visitors from Seoul, Daejeon, and the entire central corridor — a catchment area of over 20 million people within a 2-hour drive.
