Hi Heroin,
You are welcome. So you mean your house is ready in Mar-Jun or ready in the sense that renovation finish? If just get your house during that time will be a bit to early. I got my package last month, but I can hold till begining of next year to get it deliver to me as my renovation will finish only in early Dec, so by latest I can move in by Jan.
One more thing, if you pay by 31 Dec and get the furniture next year, you will only pay 3% GST but if you pay deposit for example $500 and the rest pay next year, the remaining payment will need to pay %5 GST. That will amount to about extra $90.
