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.

Home loans spanning 40 years are offered by select lenders, though the loan period is much longer than a standard 30-year home loan. You're more likely to find a maximum of 35 years, such as is the case with Teacher’s Mutual Bank. 

Currently, 40 year home loan lenders in Australia include AlphaBeta Money, BCU, G&C Mutual Bank, Pepper, and Sydney Mutual Bank.

Even though these lengthier loans 35 to 40 year loans do exist on the market, they are not overwhelmingly popular, as the extra interest you pay compared to a 30-year loan can be over $100,000 or more.

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. 

Each lender has its own policies, but as a general rule you will have to pay lender’s mortgage insurance (LMI) if your loan-to-value ratio (LVR) exceeds 80 per cent. This applies whether you’re taking out a new home loan or you’re refinancing.

If you’re looking to buy a property, you can use this LMI calculator to work out how much you’re likely to be charged in LMI.

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 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.

Real Time Ratings produces instant scores for loan products and updates them based what you tell us about what you’re looking for in a loan. In that sense, we believe the ratings are as close as you get to personalised; the more you tell us, the more we customise to ratings to your needs. Some borrowers value flexibility, while others want the lowest cost loan. Your preferences will be reflected in the rating. 

We also take a shorter term, more realistic view of how long borrowers hold onto their loan, which gives you a better idea about the true borrowing costs. We take your loan details and calculate how much each of the relevent loans would cost you on average each month over the next five years. We assess the overall flexibility of each loan and give you an easy indication of which ones are likely to adjust to your needs over time. 

We work closely with lenders to get updates as quick as possible, with updates made the same day wherever possible.

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.

When the Reserve Bank of Australia cuts its official cash rate, there is no guarantee lenders will then pass that cut on to lenders by way of lower interest rates. 

Sometimes lenders pass on the cut in full, sometimes they partially pass on the cut, sometimes they don’t at all. When they don’t, they often defend the decision by saying they need to balance the needs of their shareholders with the needs of their borrowers. 

As the attached graph shows, more recent cuts have seen less lenders passing on the full RBA interest rate cut; the average lender was more likely to pass on about two-thirds of the 25 basis points cut to its borrowers. 

‘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.

Low-deposit home loans aren’t as common as they once were, because they’re regarded as relatively risky and the banking regulator (APRA) is trying to reduce risk from the mortgage market.

However, if you do your research, you’ll find there is still a fairly wide selection of banks, credit unions and non-bank lenders that offers low-deposit home loans.

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.

An complaints officer – previously referred to as an ombudsman -looks at formal complaints from customers about their credit providers, and helps to find a fair and independent solution to these problems.

These services are handled by the Australian Financial Complaints Authority, a non-profit government organisation that addresses and resolves financial disputes between customers and financial service providers.
