Good luck with the sale of the property and good luck in getting your new house.
I'm in Adelaide and we had a house on the market, the real estate agent totally killed our property, didn't represent the house, NOTHING! We ended up sacking them.
In the end we sold the house on our own.
Lesson here: get a couple agents to look at the property that your selling and if you can sell the house yourself.
Get a qualified builder to inspect the property that you want to purchase. (Someone who has been a builder for some time)
