I was paying off a mortgage on a town house when I met my husband. I then bought a house with him, and let my parents move into my town house for life (as they didn't own a house and were nearing retirement). My dad gave me part of his super (30k) to help reduce the mortgage. They have lived in the house for 14 years. Later, I refinanced my house, and paid that mortgage off to make it easier to manage. I called up the tax office before I started the arrangement and was told that it was a granny flat arrangement and thought that meant that no CGT would be payable. I am now wondering though, what the CGT implications are for me when they eventually are living with me and the house is vacant. Have I been totally stupid?
