1) - Does that include variable also? NAB will only give advertised rate and no further discount? Does this include existing customers?
3) - When 5 yrs interest only is up, what's the likely hood of getting another 5?
1) Yes
3) With NAB it's a full application to extend IO, so will depend on what your circumstances look like then. This is nothing new though. Nothing concrete in terms of IO policy changes have been announced.
