In South Asia, land is at a premium due to high population. You can buy basically any piece of land anywhere and its value rises a lot each year. My father-in-law owns swampland in South Asia which is still rising in value despite being a huge burden to actually develop.

In addition, property ownership is limited in a way it is not in the West (only citizens can own property, as an example, in India), so it's an advantage you want to retain as a migrant over non-natives.
