My subdivision is actually DONE
So, if I fax the CBA and give them $121, I have a completely debt-free, unencumbered title to a block of land I can wave at the ANZ as a downpayment

Or just keep with the CBA.
Not quite enough to get us over the 60% mark though, land is worth loosely $50k, house build once you add on fences and connections and floor coverings will be around $110-115k, maybe more. That isn't 40%. Hence, need to pull some out of existing loan. Topping up both our existing loans and the land with the CBA to 60% barely gets us to $80k unless we swing some
very high valuations.
