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.

Equity refers to the difference between what your property is worth and how much you owe on it. Essentially, it is the amount you have repaid on your home loan to date, although if your property has gone up in value it can sometimes be a lot more.

You can use the equity in your home loan to finance renovations on your existing property or as a deposit on an investment property. It can also be accessed for other investment opportunities or smaller purchases, such as a car or holiday, using a redraw facility.

Once you are over 65 you can even use the equity in your home loan as a source of income by taking out a reverse mortgage. This will let you access the equity in your loan in the form of regular payments which will be paid back to the bank following your death by selling your property. But like all financial products, it’s best to seek professional advice before you sign on the dotted line.

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

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.

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.

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.

If you wish to return to your previous lender after refinancing, you will have to go through the refinancing process again and pay a second set of discharge and upfront fees. 

Therefore, before you refinance, it’s important to weigh up the new prospective lender against your current lender in a number of areas, including fees, flexibility, customer service and interest rate.

If your home loan was part of a package deal that included access to credit cards, transaction accounts or term deposits from the same lender, switching all of these over to a new lender can seem daunting. However, some lenders offer to manage part of this process for you as an incentive to refinance with them – contact your lender to learn more about what they offer.

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.
