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 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

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.

It’s no longer possible to get a no-deposit home loan in Australia. In some circumstances, you might be able to take out a mortgage with a 5 per cent deposit – but before you do so, it’s important to weigh up the pros and cons.

The big advantage of borrowing 95 per cent (also known as a 95 per cent home loan) is that you get to buy your property sooner. That may be particularly important if you plan to purchase in a rising market, where prices are increasing faster than you can accumulate savings.

But 95 per cent home loans also have disadvantages. First, the 95 per cent home loan market is relatively small, so you’ll have fewer options to choose from. Second, you’ll probably have to pay LMI (lender’s mortgage insurance). Third, you’ll probably be charged a higher interest rate. Fourth, the more you borrow, the more you’ll ultimately have to pay in interest. Fifth, if your property declines in value, your mortgage might end up being worth more than your home.

Bad credit home loans can be dangerous if the borrower signs up for a loan they’ll struggle to repay. This might occur if the borrower takes out a mortgage at the limit of their financial capacity, especially if they have some combination of a low income, an insecure job and poor savings habits.

Bad credit home loans can also be dangerous if the borrower buys a home in a stagnant or falling market – because if the home has to be sold, they might be left with ‘negative equity’ (where the home is worth less than the mortgage).

That said, bad credit home loans can work out well if the borrower is able to repay the mortgage – for example, if they borrow conservatively, have a decent income, a secure job and good savings habits. Another good sign is if the borrower buys a property in a market that is likely to rise over the long term.

Yes, ANZ, Commonwealth Bank, NAB and Westpac all offer guarantor home loans. These mortgages are also offered by many other banks, credit unions and building societies.

Mortgage stress is when you don’t have enough income to comfortably meet your monthly mortgage repayments and maintain your lifestyle. Many experts believe that mortgage stress starts when you are spending 30 per cent or more of your pre-tax income on mortgage repayments.

Mortgage stress can lead to people defaulting on their loans which can have serious long term repercussions.

The best way to avoid mortgage stress is to include at least a 2 – 3 per cent buffer in your estimated monthly repayments. If you could still make your monthly repayments comfortably at a rate of up to 8 or 9 per cent then you should be in good position to meet your obligations. If you think that a rate rise would leave you at a risk of defaulting on your loan, consider borrowing less money.

If you do find yourself in mortgage stress, talk to your bank about ways to potentially reduce your mortgage burden. Contacting a financial counsellor can also be a good idea. You can locate a free counselling service in your state by calling the national hotline: 1800 007 007 or visiting www.financialcounsellingaustralia.org.au.

Mortgage brokers are finance professionals who help borrowers organise home loans with lenders. As such, they act as middlemen between borrowers and lenders.

While bank staff recommend home loan products only from their own employer, brokers are independent, so they can recommend products from a range of institutions.

Brokers need to be accredited with a particular lender to be able to work with that lender. A typical broker will be accredited with anywhere from 10 to 30 lenders – the big four banks, as well as a range of smaller banks, credit unions and non-bank lenders.

As a general rule, brokers don’t charge consumers for their services; instead, they receive commissions from lenders whenever they place a borrower with that institution.

The best mortgage to suit your needs will vary depending on your individual circumstances. If you want to be mortgage free as soon as possible, consider taking out a mortgage with a shorter term, such as 25 years as opposed to 30 years, and make the highest possible mortgage repayments. You might also want to consider a loan with an offset facility to help reduce costs. Investors, on the other hand, might have different objectives so the choice of loan will differ.

Whether you decide on a fixed or variable interest rate will depend on your own preference for stability in repayment amounts, and flexibility when it comes to features.

If you do not have a deposit or will not be in a financial position to make large repayments right away you may wish to consider asking a parent to be a guarantor or looking at interest only loans. Again, which one of these options suits you best is reliant on many factors and you should seek professional advice if you are unsure which mortgage will suit you best.

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.

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.
