If the unit number/villa number is less than five, all units/villas do not need to pay for the strata fee/insurance in WA.
The developers try to build bigger space to compromise the limited land. Thus many townhouses/units/villas can have 3bedrooms*2bathrooms*2living areas. It is a modern choice if you do not have much money to buy a house.
If I do not have a pet, I will love to buy a villa/unit.
