Tenants have moved out of our IP and there have been some cracks inside and outside the property (about 5 years old). New tenants are moving in a week's time. We wanted to repair the cracks and were told by the strata manager that the costs of repairing cracks would not be claimable under the strata building insurance policy because external cracks should be repaired by the developer / builder under the builder's warranty (however builder has shot through!) and internal cracks do not come under the strata building insurance policy. So, we have decided to leave the external cracks and get the body corporate to approach the issue collectively - almost every unit in the block has cracks. But, we still want to go ahead with repairing the internal cracks at our own expense before the new tenants move in. The tradesman said that after cracks are repaired, the walls have to be repainted. So, we further decided that the whole unit needs repainting as most of the walls have cracks and marks on them. Our question is whether the costs of repairing these cracks and painting the entire unit (only inside) can be claimed as a tax deductible expense item? Or, do they form part of the CGT cost base when we sell the unit in the future? Thanks for your views.
