There are quite a few 0% balance transfer deals going around at present. If you have a home loan with an offset account and qualifying income, you can use these deals to benefit from the "arbitrage" created by the differing interest rates and seriously reduce the cost of interest on your mortgage. As an example, I took out a Bank of Melbourne credit card as linked above, with a limit of $32,000. I did a balance transfer for $30,000 which will attract 0% interest for 20 months. My home loan rate is about 4.3%pa. Over 20 months, this will save me around $1,500 in interest and help me to pay off the loan faster. It's basically free money and definitely worthwhile!
There are a few catches, but they are not really deal breakers in my opinion
* You need to make the minimum repayments on the credit card, which will reduce your savings from the theoretical maximum
* You might need to pay an annual fee - in this case $99/yr, but you can reduce that to $nil if you open a transaction account first and put $2,000 through it a month. Even if you couldn't be bothered with putting $2,000 through it you can open the account and not use it, attracting a $3/mo fee, reducing the annual fee to $36. In any case, the savings easily pay for the annual fee.
* Other credit providers may charge other fees, like a "once off BT fee" of 1.5% - these will reduce your profit.
* It may not be great for your credit rating, but provided you pay it off on time I don't see how it could be terrible either. If you need to borrow more money for another reason and don't want this showing up in your debt commitments then you could always close it off earlier than the 20 months.
My back of the envelope maths say the maximum you could save with this is $2,150 - but actually maximum would be higher than this, as by paying less interest for 20 months you will pay off more principal, reducing your ongoing interest. I'm sure there is a way to figure out exactly what this amounts to - if someone is a finance wizz please tell us!
The terms specify transfers are only to be from:
"request at application to transfer balance(s) from non- St.George, Bank of Melbourne and BankSA Australian issued credit, charge or store cards."
How did you get your mortgage transfer approved?
