Big bank cashback trap costs Aussie home buyers nearly $40,000

If you’re planning to take out a mortgage with a big bank for the sake of their $2,000 cashback, it might be time to rethink your options. New research from Mozo has found Aussie home loan borrowers hopping onto the cashback bandwagon could be ripped off $37,294 over the life of their loan by not shopping around for a more competitive deal.* 

Mozo’s findings reveal that even if you spent the entire $2,000 cashback on making monthly repayments, the savings would disappear in the first 18 months on a $300,000 loan and in just 6 months on a $1,000,000 loan.** 

Among major banks including Westpac, St George, Commbank and NAB, a total of 7 of these cashbacks were offered to home loan customers.

Mozo Director Kirsty Lamont said while these cashback offers seem like a good catch short term, they end up imprisoning borrowers inside bad rates that you could be stuck with for decades. 

“Home loans are a long term commitment and if you set and forget your loan after banking a cashback offer you could be trapping yourself with a poor interest rate and higher monthly repayments,” Lamont said. 

“Don’t believe the hype when it comes to home loan cash back offers. Your best option is always to compare what’s on offer and go with the most competitive rate.” 

The big banks vs online lenders: what’s the difference in their rates?  

Mozo data shows that the big banks definitely aren’t your best bet if you’re looking for an affordable home loan. Online lenders have risen as true movers and shakers in the mortgage market, offering customers much lower interest rates and fees. 

In terms of average numbers, the Big 4’s variable interest rate now sits at 4.10%^, having dropped 139 basis points from 5.44% since 1 January 2015. Meanwhile, over the same period, the average variable rate for online lenders has fallen further, going down 150 basis points from 4.96% to 3.46%.

“On average, the big four banks’ variable interest rates are still 64 basis points above the average of the online lenders. So if you’re looking to cut your repayments, online lenders offer you a ticket out of the big banks’ high interest rate cashback trap,” Lamont said. 

Even when you place the big banks’ cheapest rates side-by-side with those of leading online lenders, there continues to be a 31 basis point difference between the two.

In fact, two thirds of lenders in Mozo’s comparison database now offer variable rates below 3.50%, which beat the big bank average. And the lowest rates in our database - drumroll, please - start from as low as 2.89% with Reduce Home Loans!
