My very first home. Unit vs subdivision strategy

I have read this thread all the way through…….it is very informative……….but I could not find the answer that I was looking for. Could the experts here please help me with the following?

My Question……..

I want to buy a vacant land and subdivide it and build multiple units (4 or 6 units). However, I have the following questions:

1.       Shall I buy it under company or under my personal name?

2.       Regarding Capital Gain Tax, I heard that there will be 50% discount if I hold asset for more than 12 months. When shall I start to count the 12 months, from the settlement of land or from the construction of the building or from the time of subdivision or title issues?

3.       50% CGT discount apply to personal purchase or company purchase?

Thanks
