The cost of repairs and maintenance you do (or pay someone else to do) on the rentalproperty is normally deductible as an expense.
Examples of repairs and maintenance are:
• replacing a broken shower head
• plastering and painting a crack in the wall
• replacing a blown element in a hot water cylinder
• redecorating the property so that it's in the same condition it was in when you bought it to use as a rental property.
If you do the repairs yourself, you can't claim your time as an expense, only the materials you purchase.
There are some circumstances when the cost of repairs can't be deducted as an expense because they're considered a capital improvement, such as where you:
• buy a rundown property and spend large sums of money on it to significantly improve or alter it before renting it out.
• carry out work which significantly improves the property, for example you take down a badly deteriorated wall and put a conservatory in its place.
