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.

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.

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.

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.

If you want to get a home loan with bad credit, you need to convince a lender that your problems are behind you and that you will, indeed, be able to repay a mortgage.

One step you might want to take is to visit a mortgage broker who specialises in bad credit home loans (also known as ‘non-conforming home loans’ or ‘sub-prime home loans’). An experienced broker will know which lenders to approach, and how to plead your case with each of them.

Two points to bear in mind are:

• Many home loan lenders don’t provide bad credit mortgages
• Each lender has its own policies, and therefore favours different things

If you’d prefer to directly approach the lender yourself, you’re more likely to find success with smaller non-bank lenders that specialise in bad credit home loans (as opposed to bigger banks that prefer ‘vanilla’ mortgages). That’s because these smaller lenders are more likely to treat you as a unique individual rather than judge you according to a one-size-fits-all policy.

Lenders try to minimise their risk, so if you want to get a home loan with bad credit, you need to do everything you can to convince lenders that you’re safer than your credit history might suggest. If possible, provide paperwork that shows:

• You have a secure job
• You have a steady income
• You’ve been reducing your debts
• You’ve been increasing your savings

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.

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.

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.

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.

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.

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.
