Well I just rediscovered this blog. Turns out the agent never bothered to get back to me on the Nashi block, he was too busy selling it to somebody else. Turned out for the best as I now own a much larger block nearby that was only slightly more expensive.
My land is two lots each of which is split, two are side by side so I have 3 separate blocks: one on Parker Rd, one on Orara Way and one beside a railway line that I haven't even seen yet as there is only a rough track.
I had to wait till we sold another place but I finally owned it 20 Nov 2009.
