11 Most expensive mansions in the world that were built but no one ever lived in- Reasons will shock you (With Pictures)

10. 16 Empty Mansions Out of 66

You might have never known of this and wondered why these huge mansions and elegant houses have been left vacant by billionaires for years. But, leaving a property vacant for years, especially the large mansions and estates of this kind, is actually beneficial for the billionaires in a number of ways. If such a property is left vacant for several years by an owner, he gets tax concessions on them. In the UK, the properties that are left vacant or abandoned by owners for more than two years qualify for reduced cost of renovation. And, if such as a structure is later leveled and newly built, there is absolutely zero VAT applicable on the building costs.
