Hi My Dad died last year and my mums house has a granny annex. My family will be moving into the main house (it will become our main residence) and she would like to live in the Granny annex - so we can look after her. I know that if she gifts the property 100% to me then she has to pay me a market rent so that it is a gift without benefit & then you enter into the 7 year gift rule. My question is though, can she make me a common tenant as a gift on the deed so I own 70% and she owns 30%. So she retains the granny annex and doesn’t pay rent. Then would her 30% be treated under the resident nil band (subject to changes in the budget in the next month) So she gifts away part of her main residence. She wants to downsize but it makes sense for her to be living next door to us & her grandchildren. Thanks
