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.

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.

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.

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.

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.

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.

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.

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 guaranteed home loan involves a guarantor (often a parent) promising to pay off a mortgage if the principal borrower (often the child) fails to do so. The guarantor will also have to provide security, which is often the family home.

The principal borrower will usually be someone struggling to find the money to enter the property market. By partnering with a guarantor, the borrower increases their financial power and becomes less of a risk in the eyes of lenders. As a result, the borrower may:

• Qualify for a mortgage that they would have otherwise been denied
• Not be required to pay lender’s mortgage insurance (LMI)
• Be charged a lower interest rate
• Be charged less in fees

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.

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.

‘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.

No Cost Refinancing is an option available in the US where the lender or broker covers your switching costs, such as appraisal fees and settlement costs. Unfortunately, no cost refinancing isn’t available in Australia.

Whether you’re a new borrower or you’re refinancing your home loan, many lenders require you to be in a permanent job with the same employer for at least 6 months before applying for a home loan. Different lenders have different requirements. 

If your work situation changes for any reason while you’re applying for a mortgage, this could reduce your chances of successfully completing the process. Contacting the lender as soon as you know your employment situation is changing may allow you to work something out. 

Some lenders will allow you to apply for a mortgage if you are a contractor or freelancer. However, many lenders prefer you to be in a permanent, ongoing role, because a more stable income means you’re more likely to keep up with your repayments.

If you’re a contractor, freelancer, or are otherwise self-employed, it may still be possible to apply for a low-doc home loan, as these mortgages require less specific proof of income.
