Koh Samui is located towards the southern tip of Thailand, and as such, although not quite there, it is incredibly close to the equator. This tends to make it very hot for most of the year. One of the impacts this has, as with any holiday destinations that have hot whether, is that much of the accommodation has pools that come with it. Even compared to other warm destinations Koh Samui is hot and all year, even in the monsoon season. It's not the sort of place you want to sunbathe without being in close proximity to a body of water.
Now this means that you will look to buy or build a villa with a pool. This means you need a quality builder to do this, as the island has the sort of land that requires a good build quality. Along with this, pools are notoriously hard work to maintain, and this is not a job you will want to involve your self in while you are here on holiday, or in fact at any other time. It's also something that you will be unable to do when you are not here. This means that you need a good quality maintenance service.
The weather here also means that property requires constant maintenance. Due to the high temperatures mixed with high rainfall – it would take long for nature to reclaim the island in the absence of a human presence, and this can be easily seen with badly maintained property.
