Hi El caballo,
I have no preference between house or unit/apartment as long as price is right. Few rules about what type of apartment, number of units, carparking etc but as a general rule happy to buy units and apartments. My experience is they have grown just as well if not better than houses in many areas.
I am though against new houses and apartments, very very rarely would i consider buying one and have only ever bought three . Ultimately a property becomes only land value so the higher the land content at the beginning the higher the growth should be long term. The newer the property the lower the land content tends to be as much value is in the actual building.
BTW i don't subscribe to the no land content in apartments, there certainly is based on its location and the ability it provides to get into an area that would otherwise be unattainable for many. That creates a land content and has a real value.
Cheers and good luck
BT
