Really?! That's excellent
Maybe they were only saying that for "my protection". Thanks for that!

I am in SA and I've just been looking at http://www.revenuesa.sa.gov.au/ checklist

Is each applicant and their spouse/domestic partner a person who has never owned a residential property jointly, separately or with some other person before 1/7/2000, in any State or Territory of Australia?

As my partner purchased her property with her parents in 2001, this means that the answer to this question is YES? I'm just confused why it makes a difference whether it's before or after 1/7/2000

The first property wasnt an investment. It was a holiday house. It was in three people's names and she was the only one whose first property that was. This is why she didnt get the frist home owner's grant
We are currently living together but not at the time she purchased the first property. We will be getting married soon…
