Pisces,
Just quickly, it is a medium density zoned area, confirmed this with council when I rang them to ask about possibility of building units (i.e. dual occupancies).
I appreciate your view on the matter, however, as I mentioned, I am giving the whole thing a miss; at present I see better opportunities in diversifying areas of investment, rather than paying too much for a house simply because it is next door to my own.
Many thanks again,
Jo
