How much can I borrow for my home loan?

Your questions answered

It all boils down to:

  • How quickly you can save, and your desire to be in your first home sooner: So, what is the minimum deposit for a home loan? The figure of 20% being required for a deposit is a common one, but lenders across the country will usually accept a deposit somewhere in the vicinity of 5% to 25%. Of course, if you’re comfortable to wait until you have 20% of your purchase price saved, by all means go for it – you’ll be a more attractive prospect for many lenders. However, if you’re desperate to have your own place sooner, there are options available to you.
  • What your lender will do in terms of a deposit percentage: Different lenders will accept varying deposit amounts when applying for a home loan. For example, at Greater Bank, we’re able to accept deposits as low as 5%, however in situations like this, you may be required to purchase what’s known as Lender’s Mortgage Insurance (LMI). For more on LMI, see below. We also get asked a lot – “Can I get a home loan without a deposit?” and another option that may be open to would-be buyers looking to get into the market sooner is our Family Pledge Loan. In situations where a potential buyer isn’t able to save the full 20% deposit amount, they may be able to use equity in a parent or guarantor’s property to secure their own home loan.

  • Whether you’re prepared to accept LMI: LMI is basically a one-off payment you make when you’re unable to save the full 20% deposit amount for your home. It protects the lender in the event you become unable to meet your loan repayments and default on the loan at any point. The amount you pay in LMI is linked to your saved deposit amount – the smaller your deposit percentage, the larger the amount you pay in LMI. The good thing is, however, that at Greater Bank, you are able to include your LMI payment in the total cost of your loan, meaning you can repay it over time in addition to your loan repayments, and get into your new place sooner.

Terms, conditions, fees, charges and credit criteria apply.

Primarily, your borrowing power is determined by getting an overall picture of how favourable you are as a candidate for a loan.

This picture comes together by taking into account your income level, your current expenses, how much debt you are currently servicing, and your relationship with credit in the past.

A very wise question. Many loan applicants look at their borrowing power as communicated by a lender, and think that this is the amount they need to borrow.

It's wise to think in terms of what you can afford to borrow. That is to say - how much debt can you take on that won't have a negative impact on your life, regardless of whether your financial circumstances remain the same, or change in the future.

Calculator Disclaimer

This calculator should be used as an indication only. Results provided are estimates for illustrative purposes and based on the information provided and the assumption that calculations are for new borrowings only. These assumptions are subject to change. Results should not be relied on or construed as financial or other advice. Results do not represent a quote or pre-qualification for a loan or other product.

This calculator applies the Household Expenditure Measure (HEM) to pre-populate minimum living expenses, to ensure that you allow adequate funds to live on. We include an interest rate buffer in our calculations. This allows us to factor in, to a degree, the effect of interest rate increases when working out how much you may be able to afford.

Calculations are not a loan or other product approval. Applications for credit are subject to credit approval and satisfactory security and minimum deposit requirements. Other criteria also apply. Conditions apply to all loans and other products. Full terms and conditions will be set out in our loan or other product offer, if an offer is made.

Fees and charges are payable. Interest rates are subject to change. The calculations do not take into account fees, charges or other amounts that may be charged to your loan or other account (such as establishment fees or stamp duty). Lender's Mortgage Insurance may apply. Any of these additional amounts will increase repayments under the loan.

As this information has been prepared without considering your objectives, financial situation or needs, you should consider its appropriateness to your circumstances before acting on it. You should obtain financial and taxation advice from a suitably qualified and experienced professional adviser before making a financial decision.
