Here is the way, I see it:
1. New home will automatically come with, bond payments.
2. Pre-existing homes can have no bond, very little bond, or are still paying their bond.
As my uncle used to say, "first you see what you like and then buy what you can afford".
3. You must own the house, and not have the house owned you!!!! If the bond puts you in a position with strained finances, then look for a more affordable home.
4. the only place on earth where you live like a miiliionaire, at not millioaire prices. IMHO
I wouldn't let the bond, stop me from enjoying this great place, called TV.
