Interest Only Home Loan

What is an interest only mortgage?

An interest only mortgage differs to a standard variable rate loan. Standard variable home loans are the most popular loan type in Australia today, and generally consist of a good degree of flexibility and allow for home owners to make additional repayments on their loan early without being slapped with a fee. Because the interest rate of a standard variable home loan fluctuates with the cash rate set by the Reserve Bank of Australia, when interest rates rise, so do all your repayments. The same applies to rate cuts, so if interest rates go down, so do your repayment amounts.

Assuming the borrower has whipped out a home loans calculator to calcuate their budget and has been consistent with their repayment amounts they should find themselves free of debt at the end of the loan period. But still, with ever increasing housing prices and today’s tough economic climate, interest only home loans have become more popular.

How does an interest only loan work?

Interest only loans are a type of loan whereby the borrower only has to pay the interest on the principal balance. Because they are only required to repay the interest section, the major benefit lies in lower monthly repayments, which is why these loans are primarily intended for people purchasing investment properties. In theory, the loan will never need to be completely paid off, provided that the interest payments are made regularly.

Some loans can also be split with an interest-only portion to trim down the repayments necessary in the first few years of the loan. This will essentially reduce repayment amounts and keep cash flow at a higher level. Use our home loans calculator to see the difference between the principal and interest loan repayments and interest only loan repayments.  

Is interest only the best loan for me?

Interest only loans will generally work to the advantage of the regimented investor or people who are building or renovating their own home and have not stretched their borrowing power or loan to value ratio (LVR) to the breaking point.

They are a good option in the short term and can provide some ease if you are just settling into making repayments on your mortgage. These loans are best to be considered for terms between five and seven years as this is the average time a home is occupied before re-financing and selling. As with any investment, the larger the amount the more substantial the savings will be. Therefore larger mortgages will receive the most savings benefits from an interest only loan.

What is an interest-only loan? How do I work out interest-only loan repayments?

An ‘interest-only’ loan is a loan where the borrower is only required to pay back the interest on the loan. Typically, banks will only let lenders do this for a fixed period of time – often five years – however some lenders will be happy to extend this.

Interest-only loans are popular with investors who aren’t keen on putting a lot of capital into their investment property. It is also a handy feature for people who need to reduce their mortgage repayments for a short period of time while they are travelling overseas, or taking time off to look after a new family member, for example.

While moving on to interest-only will make your monthly repayments cheaper, ultimately, you will end up paying your bank thousands of dollars extra in interest to make up for the time where you weren’t paying off the principal.

How can I calculate interest on my home loan?

You can calculate the total interest you will pay over the life of your loan by using a mortgage calculator. The calculator will estimate your repayments based on the amount you want to borrow, the interest rate, the length of your loan, whether you are an owner-occupier or an investor and whether you plan to pay ‘principal and interest’ or ‘interest-only’.

If you are buying a new home, the calculator will also help you work out how much you’ll need to pay in stamp duty and other related costs.

What is 'principal and interest'?

‘Principal and interest’ loans are the most common type of home loans on the market. The principal part of the loan is the initial sum lent to the customer and the interest is the money paid on top of this, at the agreed interest rate, until the end of the loan.

By reducing the principal amount, the total of interest charged will also become smaller until eventually the debt is paid off in full.

What happens to my home loan when interest rates rise?

If you are on a variable rate home loan, every so often your rate will be subject to increases and decreases. Rate changes are determined by your lender, not the Reserve Bank of Australia, however often when the RBA changes the cash rate, a number of banks will follow suit, at least to some extent. You can use RateCity cash rate to check how the latest interest rate change affected your mortgage interest rate.

When your rate rises, you will be required to pay your bank more each month in mortgage repayments. Similarly, if your interest rate is cut, then your monthly repayments will decrease. Your lender will notify you of what your new repayments will be, although you can do the calculations yourself, and compare other home loan rates using our mortgage calculator.

There is no way of conclusively predicting when interest rates will go up or down on home loans so if you prefer a more stable approach consider opting for a fixed rate loan.

Remaining loan term

The length of time it will take to pay off your current home loan, based on the currently-entered mortgage balance, monthly repayment and interest rate.

Who has the best home loan?

Determining who has the ‘best’ home loan really does depend on your own personal circumstances and requirements. It may be tempting to judge a loan merely on the interest rate but there can be added value in the extras on offer, such as offset and redraw facilities, that aren’t available with all low rate loans.

To determine which loan is the best for you, think about whether you would prefer the consistency of a fixed loan or the flexibility and potential benefits of a variable loan. Then determine which features will be necessary throughout the life of your loan. Thirdly, consider how much you are willing to pay in fees for the loan you want. Once you find the perfect combination of these three elements you are on your way to determining the best loan for you. 

What is the best interest rate for a mortgage?

The fastest way to find out what the lowest interest rates on the market are is to use a comparison website.

While a low interest rate is highly preferable, it is not the only factor that will determine whether a particular loan is right for you.

Loans with low interest rates can often include hidden catches, such as high fees or a period of low rates which jumps up after the introductory period has ended.

To work out the best value for money, have a look at a loan’s comparison rate and read the fine print to get across all the fees and charges that you could be theoretically charged over the life of the loan.

Can I take a personal loan after a home loan?

Are you struggling to pay the deposit for your dream home? A personal loan can help you pay the deposit. The question that may arise in your mind is can I take a home loan after a personal loan, or can you take a personal loan at the same time as a home loan, as it is. The answer is that, yes, provided you can meet the general eligibility criteria for both a personal loan and a home loan, your application should be approved. Those eligibility criteria may include:

  • Higher-income to show repayment capability for both the loans
  • Clear credit history with no delays in bill payments or defaults on debts
  • Zero or minimal current outstanding debt
  • Some amount of savings
  • Proven rent history will be positively perceived by the lenders

A personal loan after or during a home loan may impact serviceability, however, as the numbers can seriously add up. Every loan you avail of increases your monthly installments and the amount you use to repay the personal loan will be considered to lower the money available for the repayment of your home loan.

As to whether you can get a personal loan after your home loan, the answer is a very likely "yes", though it does come with a caveat: as long as you can show sufficient income to repay both the loans on time, you should be able to get that personal loan approved. A personal loan can also help to improve your credit score showing financial discipline and responsibility, which may benefit you with more favorable terms for your home loan.

What are extra repayments?

Additional payments to your home loan above the minimum monthly instalments, which can help to reduce the loan’s term and remaining payable interest.

How do I calculate monthly mortgage repayments?

Work out your mortgage repayments using a home loan calculator that takes into account your deposit size, property value and interest rate. This is divided by the loan term you choose (for example, there are 360 months in a 30-year mortgage) to determine the monthly repayments over this time frame.

Over the course of your loan, your monthly repayment amount will be affected by changes to your interest rate, plus any circumstances where you opt to pay interest-only for a period of time, instead of principal and interest.

What is a fixed home loan?

A fixed rate home loan is a loan where the interest rate is set for a certain amount of time, usually between one and 15 years. The advantage of a fixed rate is that you know exactly how much your repayments will be for the duration of the fixed term. There are some disadvantages to fixing that you need to be aware of. Some products won’t let you make extra repayments, or offer tools such as an offset account to help you reduce your interest, while others will charge a significant break fee if you decide to terminate the loan before the fixed period finishes.

Can I get a NAB home loan on casual employment?

While many lenders consider casual employees as high-risk borrowers because of their fluctuating incomes, there are a few specialist lenders, such as NAB, which may provide home loans to individuals employed on a casual basis. A NAB home loan for casual employment is essentially a low doc home loan specifically designed to help casually employed individuals who may be unable to provide standard financial documents. However, since such loans are deemed high risk compared to regular home loans, you could be charged higher rates and receive lower maximum LVRs (Loan to Value Ratio, which is the loan amount you can borrow against the value of the property).

While applying for a home loan as a casual employee, you will likely be asked to demonstrate that you've been working steadily and might need to provide group certificates for the last two years. It is at the lender’s discretion to pick either of the two group certificates and consider that to be your income. If you’ve not had the same job for several years, providing proof of income could be a bit of a challenge for you. In this scenario, some lenders may rely on your year to date (YTD) income, and instead calculate your yearly income from that.

Can I apply for an ANZ non-resident home loan? 

You may be eligible to apply for an ANZ non-resident home loan only if you meet the following two conditions:

  1. You hold a Temporary Skill Shortage (TSS) visa or its predecessor, the Temporary Skilled Work (subclass 457) visa.
  2. Your job is included in the Australian government’s Medium and Long Term Strategic Skills List. 

However, non-resident home loan applications may need Foreign Investment Review Board (FIRB) approval in addition to meeting ANZ’s Mortgage Credit Requirements. Also, they may not be eligible for loans that require paying for Lender’s Mortgage Insurance (LMI). As a result, you may not be able to borrow more than 80 per cent of your home’s value. However, you can apply as a co-borrower with your spouse if they are a citizen of either Australia or New Zealand, or are a permanent resident.

How long does Bankwest take to approve home loans?

Full approval for a home loan usually involves a property valuation, which, Bankwest suggests, can take “a week or two”. As a result, getting your home loan approved may take longer. However, you may get full approval within this time if you applied for and received conditional approval, sometimes called a pre-approval, from Bankwest before finalising the home you want to buy.  

Another way of speeding up approvals can be by completing, signing, and submitting your home loan application digitally. Essentially, you give the bank or your mortgage broker a copy of your home’s sale contract and then complete the rest of the steps online. Bankwest has claimed this cuts the approval time to less than four days, although this may only happen if your income and credit history can be verified easily, or if your home’s valuation doesn’t take time.
