Many foreigners have chosen Thailand as their retirement homes. Some move to Thailand to live and start businesses. Relatively low cost of living, good climate, Thai hospitality are among the reasons. Broadband Internet and other telecommunications infrastructure in Thailand has become more of international standards and very affordable pricing. Many international schools have popped up lately in Bangkok and major cities of Thailand to cater for both Thai and foreign children.
In fact, more people have bought properties in Thailand for the purpose of moving to and living in Thailand or for pure investment. See my previous post about Thailand property market here.
