I was about to buy a property, renovate it and sell. Initial plans were for a total project of around 15 months from buy to sell. However, planning & permits alone will take 12 to 18 months and so I've decided to rent the property prior to works commencing. This will also help with cashflow. Depending on the renovation, I may then decide to rent again or sell. In the first case, interest would be added to the cost base and would reduce any capital gains on disposal (as opposed to being deductible). In the second case, interest while the property is rented would be deductible, but what about after? Does interest continue to be deductible during the renovation phase on the basis the property will be rented again? Any recommendations? Thanks in advance.
