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.

Your current home loan interest rate. To accurately calculate how much you could save, an accurate interest figure is required. If you are not certain, check your bank statement or log into your mortgage account.

‘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.

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.

Negotiating with your bank can seem like a daunting task but if you have been a loyal customer with plenty of equity built up then you hold more power than you think. It’s highly likely your current lender won’t want to let your business go without a fight so if you do your research and find out what other banks are offering new customers you might be able to negotiate a reduction in interest rate, or a reduction in fees with your existing lender.

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 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.

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.

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.

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. 

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.

If your deposit was less than 20 per cent of your property’s value when you took out your original loan, you may have paid lenders’ mortgage insurance (LMI) to cover the lender against the risk that you may default on your repayments. 

If you refinance to a new home loan, but still don’t have enough deposit and/or equity to provide 20 per cent security, you’ll need to pay for the lender’s LMI a second time. This could potentially add thousands or tens of thousands of dollars in upfront costs to your mortgage, so it’s important to consider whether the financial benefits of refinancing may be worth these costs.

There is no set limit to how many times you are allowed to refinance. Some surveyed RateCity users have refinanced up to three times.

However, if you refinance several times in short succession, it could affect your credit score. Lenders assess your credit score when you apply for new loans, so if you end up with bad credit, you may not be able to refinance if and when you really need to.

Before refinancing multiple times, consider getting a copy of your credit report and ensure your credit history is in good shape for future refinances.

Some lenders still allow you to apply for a home loan if you have impaired credit. However, you may pay a slightly higher interest rate and/or higher fees. This is to help offset the higher risk that you may default on your repayments.

Applying for home loans with multiple lenders at once can affect your credit history, as multiple loan applications in short succession can make you look like a risky borrower. Comparing home loans from different lenders, assessing their features and benefits, and making one application to a preferred lender may help to improve your chances of success

No, given the way the loan and title transfer works, you will not have to pay two mortgages at the one time. You will make your last monthly repayment on loan number one and then the following month you will start paying off loan number two.
