Someone advised you to sell only to buy another? What about the CGT, legals, commission on the sale and stamp duty, legals, bank fees on the new purchase. This could amount to a fortune

yes, i think so

Yes, i think so because the requirement is that someone is eligible if they have never owned an owner occupied house before.

4. yes

you could get yourself into all sorts of trouble by doing it yourself.
Do you understand all the roles of those in the trust? What the effect of naming someone makes?

The consequences of getting it wrong can be extremely costly. 

Generally GST is payable on all new residential property. 'New' is classed as built less than 5 yrs ago.

I think CGT would be payable as well assuming there was a gain after expenses – unless it was your main residence – and it cannot be your main residence until you have lived in it. I think there is a tax ruling on this.

I am afraid there is no stamp duty exemption to transfer properties (in NSW) from one name to two unless it is the pinciple residence (and would therefore be usually land tax exempt anyway), s67 duties act.

Divorcing doesn't really help either as stamp duty is only exempt if going to 2 names to 1, s68.

A is an arrangement where A owns something for B. A parent opening a bank account for a child for example. Cost nil.

If you want a more complex trust, then you will need a deed. Deeds can cost from about $100 up to $10,000 depending on the type of the deed and the person drafting it.

In many States there is stamp duty payable on the deed. In NSW this is about $550, depending on the inital settled sum.

If you want a company as trustee, then you will need to pay the company set up costs and the ASIC fee of $400. There is an annual ASIC fee of $212 as well.

Companies and trusts will need tax returns, accountants fees usually depend on how complex it is – the more properties the more costs invovled (but you will pay this anyway with owning in your own names).

By 'join' do you mean beneficiary? if so anyone can be a beneficiary, even people who don't exist yet – future grandchildren etc. To be a beneficiary they have to be named, or fall into a class – such as grandchild.

Foreigners can be beneficaries – but there are tax implications. Certain incomes have withholding taxes which vary depending on the type of income (royalties, dividends etc), and the recipient may also have to pay tax in their home countries as well

Discretionary trusts allow the greatest tax flexibility as the trustee can choose who to distribute to each year (from a range of beneficiaries). To save tax they usually distribute to the lower income tax payers first, so that less tax is paid overall. Children can also earn about $2600 pa each in unearned income each year before they have to pay tax.

guarantees don't mean much. Pretend it doesn't exist when you do your calculations.
