They were easy enough (we went through a broker)
Make sure you have any paperwork they may want ready makes it a lot easier when they ask for it and approvals a lot smoother, are you entitled to first home owners grant?
Also their is another grant to help with fees when buying established which you could be eligible for?
When we built we only paid $100fn whilst it was under construction.
We are paying two mortgages now but the first mortgage is still cheaper than renting.
We were ahead in payments with them so when my partner lost his job for a couple of weeks until he found a new one we could stop payments during that time.

We only paid $3000 out of pocket for a deposit and the home owners grant covered the rest.
