Transferring a parent's house to child

As a tax saving measure or as estate planning, what is the impact of “selling” my house to one of my children, holding the mortgage and paying rent to them that happens to be the same amount as the mortgage payment? Is or would this be legal? And what would the ramifications be on the government lookback, etc.?
