CBA obviously do a lot right to get the market share they have. In addition to normal competitive interest rates some stand out policies/ niches are listed below -

Multiple offset accounts:- 100% of the money in your Everyday Offset will be deducted from your home loan balance before interest is charged. Maximise the benefits of offsetting by linking multiple Everyday Offsets to an eligible CommBank home loan, provided they're in the name(s) of the loan borrowers. The more money you have in your Everyday Offset, the less interest you'll pay on your home loan. CBA customers saved an average of $1,158 last year using their Everyday Offset.

Home buying hub:- Once you've received conditional pre-approval for your home loan, the CommBank Home Hub can help you take care of all your home buying needs: Search for properties on the go and see upcoming inspection times, Make confident decisions with personalised insights and CommBank market estimates, Know the steps you'll need to take throughout your home buying journey, Access guidance articles, tools and calculators for each step along the way.

Compassionate care:- CBA know it's a difficult time when you or someone in your family is diagnosed with a terminal illness or passes away. That's why they help support you with your home loan, so you can focus on the things that matter. Home Loan Compassionate Care is complimentary protection for your eligible Owner Occupied home loan that helps support you by paying your home loan repayments for around 12 months if you, your spouse or dependant passes away or is medically certified with a terminal illness.
