I know. I'm saying I think most people would still prefer to be 10km out.
It's just about risk-reward. While there could be some profits in there, such a large scale development may also lose a lot of money especially if the people doing it are not tier 1 developers of that nature (ie not the Grocon family etc). Not my call anyway - it's my folks who are even more conservative than me, especially at their age.
I just don't see the need to exhaust the option value of land to take on such a huge risk, when holding it will probably on the balance of probabilities net equally significant, but far lower risk capital growth (most said land have gone up 6-7x in value).
Perhaps if the land was bought recently and there's lots of debt to it, it'd be a different story - and that's only because one would have bought with the view of deveoping the land in the first place.
good call!
