Yep sure can.
But you would only do this if your planning on selling OR produce equity...not really for a "holding purpose" as your holding cost goes up
- No strata ( if you hold both) but insurance is more expensive
- 2 x council rates
- land value tend to go up so high land tax ( not sure if this is the case for all areas)
- Water rates etc..
it depends on the council, just need to read the DCP and apply for a DP.
