Currently have an AmEx Platimum Edge, looking to get a Coles Mastercard this month and may cancel the AmEx early next year (before annual fee is due).
Also will need to apply for a mortgage (investment use) mid/late next year.
Will the history of having 2 credit cards affect my credit quota? Or as long as I cancel one/all before mortgage application will be fine?
PS I have adjusted my current AmEx to 7k limit and that got me just through the line to get a pre-approval when I last applied early this year. However as I ended up putting deposit to a off-the-plan, that pre-approval won't be valid anymore and need reapply.
The number of credit cards you had in the past isn't a factor unless you were late in paying them/defaulted on them.
What the approval/pre-approval process looks at is your total potential current liability at the time of the application (e.g. if you have a CC with $20k limit, it'll treat it as worst case scenario that you could rack up a $20k debt when your loan is drawn down).
Obviously if you have a mortgage broker/banker, talk to them as well, but that's my understanding of it.
