In the Help to Buy guide, it’s stated that you cannot own two homes. You cannot buy a home using the Help to Buy scheme if you have owned a property overseas. It also applies to properties abroad since Help to Buy aims to help you move up in the housing ladder. That being the case, your Help to Buy home must be your only residence. Therefore, it is expected for you to sell your current home, here or abroad, to own a house through the Help to Buy scheme.
