Can I increase my home loan to buy a car?

If the time has come to upgrade to a new set of wheels, but your savings won’t quite cover the purchase cost, you might be weighing up your financing options.

What is understandably at the top of the list for most is the loan product’s interest rate, and it makes sense to want to find the lowest rate that’s available to you.

Often, even the most competitive interest rate car loans will still have a higher interest rate than your home loan, and that has a lot to do with the fact that car loan terms are typically around 20 years shorter than home loan terms.

Cars also typically depreciate in value over time, whereas homes are generally more likely to see an increase in value over time. This makes your car loan a bigger risk to the bank than your home loan.

Regardless, this might leave you wondering whether you can add a car loan to your home loan, in order to access a lower interest rate.

There are a couple of potential options you may have if you want to increase your home loan to buy a car:

  1. Use your redraw facility, or;
  2. Refinance your home loan to access additional funds.

However, it’s important to understand the potential risks associated before going down that route. 

How can I add a car loan to my home loan?


If you’ve been somewhat routinely making extra repayments on your home loan that amount to at least the purchase cost of your desired new vehicle, you could potentially redraw these funds from your home loan account to buy the car.

If your home loan does offer a redraw facility, this could be a reasonably fast and easy process that doesn’t involve reapplying for finance. It would also mean that you’ll avoid having an additional loan repayment to manage.

The biggest sacrifice in taking this option is that you are essentially undoing the hard work you put into making extra repayments on your home loan. Extra repayments can potentially shorten your home loan term by a number of years, reducing your interest charges over the life of the loan. If you redraw, you’ll miss out on these savings which can cost you more money in the long run and prevent you from owning your home sooner.

Also, keep in mind that even if your home loan offers a redraw facility, you may be charged a fee for redrawing funds, plus there could be a limit to how much you can redraw.


Your second option is to refinance your home loan in order to access additional funds to buy a car. You could do this with your current lender, or switch to a new lender if that means potentially accessing a more competitive rate. 

While refinancing for this purpose will give you access to your home loan’s interest rate instead of a likely higher car loan rate, keep in mind that it also means you will be paying off your car over a much longer period of time. In fact, there’s a good chance you’ll still be paying off your car when the time comes to upgrade it again.

Despite the potential to access a lower interest rate, the considerably longer loan term will likely mean paying thousands of dollars more in interest charges over the life of the loan.

Other perceived advantages and potential long-term consequences

Often the decision to upgrade your car comes out of necessity over want. The family car may have done its dash and maintenance costs might be steadily rising at every regular service.

If this is the case, you may not have been prepared for any extra repayments additional to your current home loan repayments. Accessing your redraw or refinancing your mortgage is one way to get around adding to your regular monthly liabilities, but it will likely come at a substantial cost.

Again, depending how long is left on your mortgage term, using your home loan to buy a car without increasing your current home loan repayments will generally mean paying much more in interest charges than if you take out a separate car loan.

What are some alternative options?

Even though you can increase your home loan to buy a car, it doesn’t mean it’s the best option.

If you’re interested in keeping your overall repayment costs down without potentially adding a substantial amount to your long-term interest charges, consider these alternatives:

  • Buy used: Brand new cars depreciate in value at a steady rate, meaning buying second-hand could save you thousands and allow you to take out a smaller loan.
  • Choose a car loan on a longer term: If the cost of your immediate repayments is your biggest worry, you could reduce them by opting for a car loan with a longer loan term, such as seven years instead of five. Even though this typically means paying more interest over the life of the loan, it is still much shorter than an average 25-year mortgage.
  • Use your mortgage, but increase your repayments: If you are still interested in consolidating your mortgage and car loan, do your calculations and make extra repayments that will pay your car off over an average car loan term. Some home loan lenders will even allow you to put the amount you borrow for your car into a sub-account, potentially making it easier for you to ensure you pay it off within around five years.

What is a secured car loan?

A secured car loan is a loan that is connected to a form of security, or collateral. Generally, the security for a car loan is the car itself. If you fail to repay the loan, the lender might seize your car, sell it and then use the proceeds to recover their debt.

Where can I get a student car loan?

Student car loans are not a necessarily a product in and of themselves, but what you may be looking for is a guarantor car loan.

A guarantor car loan has a third-party act as a form of guarantee for your loan application, telling the bank or lender that if you default on your loan, someone will pay the loan repayments.

Going guarantor on a car loan is no new thing, and before internet-based credit scores, guarantor car loan applicants would apply for loans with a guarantor or property owner who could vouch for the person borrowing the loan.

To get a guarantor car loan, you’ll need someone willing to act as a guarantor for your car loan.

What is a loan term?

The loan term is the amount of time the lender gives you to repay the car loan. For example, if you take out a $20,000 car loan with a five-year loan term, you would be expected to pay off the entire $20,000 (plus interest) within five years.

What are loan repayments?

Loan repayments are the regular payments you make to pay off your car loan. Loan repayments generally occur on a monthly basis, although many lenders will also give you the option of making fortnightly or weekly loan repayments.

What is a guarantor car loan?

A guarantor car loan is a type of loan that features a guarantor on the agreement. The guarantor is a third-party individual, often a friend or relative, who guarantees the loan will be repaid if the borrower defaults on the car loan.

Guarantor car loans are often geared at people who might otherwise struggle being accepted for a secured car loan when purchasing a vehicle. Some of the reasons might include a lack of credit history such as with a student or young person, if there’s bad credit, or age as a factor such as with pensioners.

How to get a chattel mortgage?

Both businesses and individuals may use a chattel mortgage, provided that the car is being used predominantly for business purposes. 

To apply for a chattel mortgage, you need to first consider your options and choose a suitable lender that meets your requirements. Once you have selected a lender, you can apply for the loan online by filling out a form. If the lender doesn’t offer an online application process, you can either call them or visit their nearest branch. 

After you’ve applied, the lender will ask you to supply documents that confirm your identification, income, job profile, etc. If everything is in order, most lenders will arrange the loan’s settlement, so all you need to do is pick up your car!

What is proof of income?

Before giving you a car loan, lenders will ask for proof of income – documentary evidence that you earn as much as you claim you earn. Lenders will typically want some combination of tax returns, pay slips and bank statements. The reason lenders want proof of income is because they want to be sure you have the means to repay the car loan.

What is dealer finance?

Dealer finance is a car loan organised through a car dealer – as opposed to car loans organised by a finance broker or directly by the lender.

What is CTP insurance?

CTP insurance, also known as compulsory third-party insurance or a green slip, is compulsory if you want to register a vehicle in Australia. If you’re responsible for a car accident, your CTP insurance will be used to pay any compensation due to anyone who might be injured or killed. However, CTP insurance doesn’t cover you for vehicle damage or theft.

Can you get a chattel mortgage with bad credit?

Getting approval for a chattel mortgage with bad credit may be possible, given ‘chattel’ (usually a piece of equipment or car) is put up as security for the loan. That means if you fail to repay the loan, the creditor can recover the loaned amount by repossessing and selling the car or piece of equipment. This differs from unsecured car loans, where the asset is not tied to the loan and cannot be taken if you don’t meet the repayments. 

What is a dealership?

A dealership is a car yard or a place where cars are sold.

Who can go guarantor for me on a car loan?

Anyone who knows your circumstances and trusts you to meet your repayments is someone who could potentially go guarantor for you on a car loan, providing that they have an excellent credit history and/or are a home owner.

Parents are the most likely to be accepted by lenders as guarantors, but immediate family such as grandparents, adult children, siblings and de facto partners are also accepted. If you want a friend of colleague to go guarantor for you it is possible but may require a specialist lender and may incur a premium fee.

What is residual value?

The residual value of a car is how much it will be worth at the end of a lease period. Finance companies need to calculate a car’s residual value before they can know how much to charge during the lease period. For example, if a financier calculates that a $30,000 car will have a residual value of $16,000 at the end of a five-year lease, the financier will know that it must charge $14,000 to break even on the lease – and more to make a profit.
