Hi Coop,
I live in Terrigal, but have never heard of them. But then we don't use others to source our property, we find them ourselves.
It has gotten pretty expensive in areas of the Central Coast. We have a few in Terrigal, but it's pretty hard to find anything under 400k these days here. That's not to say you can't find them, you just have to always be looking. Let us know what they say if you contact them.
Cheers,
Kathryn
