i lived in my home for 7 yrs and now renting because job is on other side of town. the renters are my friends so only an agreement is made on the agreemtn template. they pay cash and no record of payment. now if i sell the house to someone do i need to declare to ato that it is cgt exempt because i lived for 7 yrs and so on? do i even care to tell them that it is rented? how they find what is rented and what is not rented?
