My parents are elderly pensioners & are selling a house that has been in my fathers name since it was left to him in the 1950's (He built it with his dad). The house was left to him with the stipulation that his mother would live in in for the duration of her life. She passed away in 2003. This house is of course not my parents "principal residence" & has remained unoccupied since 1998, when my Grandmother went into a nursing home. The simple question is, are my parents liable for full CGT on the proceeds? Joe
