Claim this site

A$387 inc GST · 3 months

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

This site 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.

Card payment through Stripe. Have an account? Sign in. A claim is exclusive on Build Design Solutions only: it gives no right over the property, and the owner can still sell to anyone. How claims work.
