As a observation....it is not a question whether to purchase a unit or house but as to whether it is the right type of property for the demograhic in that particular suburb!
I wonder about this, given that price is claimed to be a function of demand, and the highest demand is for properties are for the 'right' demographic in an area.
Compare cheap outer suburbs like Melton, Hoppers or Werribee, an inner-ish suburb like Reservoir and a bayside suburb like Chelsea.
Hoppers, Melton or Werribee are considered popular first homebuyers areas. Hence a house that's affordable would be a reasonable fit to the market. A small unit might not be so good.
In contrast somewhere like Reservoir or Chelsea has smaller households and a high retired population. And maybe a sprinkling of young singles or couples who can't afford closer in but still want convenience. And their housing stock has more units and villas. So a small unit or villa might be quite fine and do well (given there's other compensating factors such as proximity to beach and/or CBD).
However let's compare prices.
Houses in Hoppers start in (say) the low 200s. A villa unit might be around $180 - 200k. So there's almost no price difference between the villa and the house.
Chelsea and Reservoir are quite different. Units there can be picked up starting from the low 200s. Houses might be $350k, $400k or more.
Now if the logic about demand and housing stock held up, units in Hoppers wouldn't be so expensive compared to houses. But they are!
Conversely entry level units in the inner or bayside areas wouldn't be only slightly dearer than ones in Hoppers or Melton if demand for them was so high. But compared to houses they're relatively cheaper.
Maybe 'land value component' is why, but I regard this as theoretical and probably the last consideration for most owner occupiers, which for houses at least, is most of the market.
It just doesn't make sense that supposedly low demand properties (eg units) are so expensive in outer areas (compared to houses).
Or maybe we're wrong about demand. Does the lack of housing diversity in outer areas (ie >90% houses) creates a demand for units that exceeds supply, so though rare, and with apparently low land component, units in outer areas might still be a good deal?
