Hi Fester,
Im with WBC. I'm refixing my Fixed Rate period on a few IO loans at the moment. As the new fixed term takes me over the intial 5 year IO period the bank said they will extend the IO period up to when the new fixed rate period expires.
Approx 1 month prior to it expiring they will also offer me another IO term should I wish, otherwise the loan reverts to a P&I loan at what ever the variable rate is at that time.
No valuations needed, however as my CGA strategy requires regular purchasing valuations are part of the normal refinacing regime for doing so.
cheers
