Claim this holding

A$387 inc GST · 3 months

A claim takes this holding off the market for every other member for 3 months and opens its address, lot outline, exact figures and neighbours to you.

This holding is A$387 because its best option clears a 40% margin on cost at the likely ask. Other sites are A$182. One claim credit claims any site.
