We have a unit and a townhouse. for each its about,
$50pw for rates/ water
$25pw insurance ( internal only body corp covers external )
$50pw for one bodycorp $75pw for the other.
And we spend ( on average) over the two properties about $5000 on maintenance and repairs.
Even though its a lot of "hidden" extras we are overall better off than renting in long term. ( plus as ones an investment those fees are tax deductible)
