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.

An investment loan is a home loan that is taken out to purchase a property purely for investment purposes. This means that the purchaser will not be living in the property but will instead rent it out or simply retain it for purposes of capital growth.

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.

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.

A split loan lets you fix a portion of your loan, and leave the remainder on a variable rate so you get a bet each way on fixed and variable rates. A split loan is a good option for someone who wants the peace of mind that regular repayments can provide but still wants to retain some of the additional features variable loans typically provide such as an offset account. Of course, with most things in life, split loans are still a trade-off. If the variable rate goes down, for example, the lower interest rates will only apply to the section that you didn’t fix.

Refinancing your home loan can involve a bit of paperwork but if you are moving on to a lower rate, it can save you thousands of dollars in the long-run. The first step is finding another loan on the market that you think will save you money over time or offer features that your current loan does not have. Once you have selected a couple of loans you are interested in, compare them with your current loan to see if you will save money in the long term on interest rates and fees. Remember to factor in any break fees and set up fees when assessing the cost of switching.

Once you have decided on a new loan it is simply a matter of contacting your existing and future lender to get the new loan set up. Beware that some lenders will revert your loan back to a 25 or 30 year term when you refinance which may mean initial lower repayments but may cost you more in the long run.

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. 

A variable rate home loan is one where the interest rate can and will change over the course of your loan. The rate is determined by your lender, not the Reserve Bank of Australia, so while the cash rate might go down, your bank may decide not to follow suit, although they do broadly follow market conditions. One of the upsides of variable rates is that they are typically more flexible than their fixed rate counterparts which means that a lot of these products will let you make extra repayments and offer features such as offset accounts.

The answer to this question is dependent on your personal circumstances – there is no best time for refinancing that will apply to everyone.

If you want a lower interest rate but are happy with the other aspects of your loan it may be worth calling your lender to see if you can negotiate a better deal. If you have some equity up your sleeve – at least 20 per cent – and have done your homework to see what other lenders are offering new customers, pick up the phone to your bank and negotiate. If they aren’t prepared to offer you lower rate or fees, then you’ve already done the research, so consider switching.

Following the Global Financial Crisis, no-deposit loans, as they once used to be known, have largely been removed from the market. Now, if you wish to enter the market with no deposit, you will require a property of your own to secure a loan against or the assistance of a guarantor.

The quickest way to pay off your home loan is to make regular extra contributions in addition to your monthly repayments to pay down the principal as fast as possible. This in turn reduces the amount of interest paid overall and shortens the length of the loan.

Another option may be to increase the frequency of your payments to fortnightly or weekly, rather than monthly, which may then reduce the amount of interest you are charged, depending on how your lender calculates repayments.

If you can’t pay off your guaranteed home loan, your lender might chase your guarantor for the money.

A guaranteed home loan is a legally binding agreement in which the guarantor assumes overall responsibility for the mortgage. So if the borrower falls behind on their mortgage, the lender might insist that the guarantor cover the repayments. If the guarantor fails to do so, the lender might seize the guarantor’s security (which is often the family home) so it can recoup its money.

A bad credit home loan is a mortgage for people with a low credit score. Lenders regard bad credit borrowers as riskier than ‘vanilla’ borrowers, so they tend to charge higher interest rates for bad credit home loans.

If you want a bad credit home loan, you’re more likely to get approved by a small non-bank lender than by a big four bank or another mainstream lender.

A low-deposit home loan is a mortgage where you need to borrow more than 80 per cent of the purchase price – in other words, your deposit is less than 20 per cent of the purchase price.

For example, if you want to buy a $500,000 property, you’ll need a low-deposit home loan if your deposit is less than $100,000 and therefore you need to borrow more than $400,000.

As a general rule, you’ll need to pay LMI (lender’s mortgage insurance) if you take out a low-deposit home loan. You can use this LMI calculator to estimate your LMI payment.

Australia no longer has no-deposit home loans – or 100 per cent home loans as they’re also known – because they’re regarded as too risky.

However, some lenders allow some borrowers to take out mortgages with a 5 per cent deposit.

Another option is to source a deposit from elsewhere – either by using a parental guarantee or by drawing out equity from another property.

A guarantor is someone who provides a legally binding promise that they will pay off a mortgage if the principal borrower fails to do so.

Often, guarantors are parents in a solid financial position, while the principal borrower is a child in a weaker financial position who is struggling to enter the property market.

Lenders usually regard borrowers as less risky when they have a guarantor – and therefore may charge lower interest rates or even approve mortgages they would have otherwise rejected.

However, if the borrower falls behind on their repayments, the lender might chase the guarantor for payment. In some circumstances, the lender might even seize and sell the guarantor’s property to recoup their money.

If you want to take out a low-deposit home loan, it might be a good idea to consult a mortgage broker who can give you professional financial advice and organise the mortgage for you.

Another way to take out a low-deposit home loan is to do your own research with a comparison website like RateCity. Once you’ve identified your preferred mortgage, you can apply through RateCity or go direct to the lender.

A failure to follow all or part of a contract or breaking the conditions of a contract without any legal excuse. A breach of contract can be material, minor, actual or anticipatory, depending on the severity of the breaches and their material impact.

A mortgage default occurs when you are 90 days or more behind on your mortgage repayments. Late repayments will often incur a late fee on top of the amount owed which will continue to gather interest along with the remaining principal amount.

If you do default on a mortgage repayment you should try and catch up in next month’s payment. If this isn’t possible, and missing payments is going to become a regular issue, you need to contact your lender as soon as possible to organise an alternative payment schedule and discuss further options.
