Hi  I would appreciate if any gurus can clarify me on these points:
 I am trying to use option agreement to control a property and then assign the option to a contractor for development.

This is presumed to take place on the land in NSW and I am in NSW.

1)The option amount is $5000   period 18 months – Purchase price on the attached unsigned sale&P agreement is $700,000,.
2) The developer will pay me  730,0000 to get assigned option in his favour, within 3 months of the option agreement signed.
3) Whose name should be on the buy/sale contract attached to the option?
a)my name b) my name  and  or nominee c)my name and  or assignee)
4) How much  stamp duty  for 1)me  2)developer
5) When the stamp duty  payable for 1)me 2) developer
6) I presume 30,000 is CGT event- is there any other opinion?
7) I  presume I may have to pay subject to other things, GST-is it correct understanding?
I noticed in some other post that  of PaulDobson "We overcame this challenge by including a "Higher Price" clause into the Option."  Please I would be thankful if the wordings for that Higher Price clause could be  given  here.
9) If the developer exercises the option, whether the sales and purchase contract will be signed by me or developer??
