Quick answer
A home loan top up increases your existing mortgage limit so you can borrow extra money against the equity in your home. It is used for renovations, debt consolidation, a deposit on another property or a major purchase. If your current lender declines, Ownright Custom Finance can look at refinancing or other secured options Australia-wide.

What is a home loan top up?
A top up is a request to your current lender to raise the limit on your existing home loan. If the home has gained value or you have paid the balance down, there may be equity sitting in the property that you can reach without selling. The lender looks at the numbers again, and if they are satisfied, they lift the limit and release the extra funds.
It sounds simple and sometimes it is. Other times it runs into the fact that the lender is judging you today, not the day you first borrowed. A change in income, a new debt, a recent late payment or a lower valuation can all make a top up harder than you expected.
When do people top up a home loan?
- To renovate or extend, as covered on our home extension loans page
- To consolidate credit cards and personal loans
- To pay a tax bill or other debt
- To fund a deposit on an investment property
- To buy a car, boat or other large item
- To cover a gap between selling and buying
The reason matters to the lender and, in some cases, to the tax office. Interest deductibility generally follows the purpose of the borrowing, so a top up used for an investment may be treated differently to one used for private spending. The ATO explains this on its rental property interest pages, and your accountant can confirm your position.
Top up, redraw, refinance or second mortgage: which is which?
| Option | What it is | Often suits | Watch out for |
|---|---|---|---|
| Top up | Your current lender lifts the loan limit | Owners with a lender that still likes them | Full reassessment, same lender policy |
| Redraw | Access money you have paid ahead | Small, short-term needs | Not available if you have not paid ahead |
| Refinance with cash out | A new lender repays the old loan and lends more | When your current lender will not top up | Exit and set-up costs, a fresh application |
| Separate equity loan | A new loan against the same property | Keeping the original loan untouched | Needs the first lender to agree in some cases |
| Second mortgage | A new loan ranking behind the existing mortgage | Speed, credit issues, or a lender that said no | Usually priced differently and structured shorter |
Our guide to refinance versus second mortgage goes through the comparison, and the cash-out refinance page covers the next step along.
What do lenders look at before approving a top up?
Property value. A new valuation, or a desktop assessment, sets the ceiling. Lenders usually lend only up to a set share of that value.
Your income. Recent payslips, or tax returns and BAS for the self-employed, show whether you can afford the larger loan.
Your debts and spending. Credit cards, personal loans, buy now pay later accounts and living costs are all weighed.
Your repayment record. Missed or late payments on the loan itself, or elsewhere, matter.
The purpose. Lenders may be cautious about some uses, such as paying off a tax debt or funding a speculative purchase.
Our guide to what lenders mean by serviceability explains the calculation in plain English.
Who is a top up not right for?
A top up may be the wrong tool if you are already stretched, if the extra funds are meant to prop up a failing business or if the interest cost over the full loan term outweighs the benefit. Rolling short-term debts into a 25 or 30 year mortgage can feel cheaper each month and cost more overall. That does not mean you should not do it, only that it should be a decision, not a default.
What if my lender says no?
A decline is information, not a final answer. Different lenders have different appetites for self-employed income, past credit bumps, unusual properties and large loan sizes. Our team can:
- Check whether a refinance with another lender gives you the extra funds
- Look at a separate equity loan or second mortgage
- Explore a short-term private loan to bridge the gap
- Help you tidy your file first, using our loan ready checklist
If the decline was caused by a credit issue, see our guide on what to do if your loan is declined.
How Ownright approaches a top up
Trevor Scott has spent more than 40 years in finance and he and the team start with what you need the funds for, not with a product. If a plain top up with your current lender is the sensible answer, we say so and step back. If it is not, we look at the wider market, including non-bank and private lenders that do not advertise.
Our home equity loan page sets out the broader options for releasing equity, and our second mortgage page covers the private route in detail. How fast things move depends on the lender and how quickly the paperwork arrives.
An illustration
Illustrative scenario only. An owner wants extra funds for a kitchen renovation and to clear two credit cards. Their bank declines a top up because of a recent change from employee to contractor. A broker could look at lenders that accept contractor income after a shorter track record, or a second mortgage while the contracting history builds.
What mistakes should I avoid?
- Asking several lenders at once and leaving multiple enquiries on your file
- Topping up for a purpose without checking the tax position
- Forgetting that a longer loan term means more interest overall
- Not keeping records of how funds were used
- Using equity to cover a recurring shortfall rather than a one-off need
What documents should I have ready?
- Recent loan statements and a rates notice
- Payslips, or tax returns and BAS
- A list of debts you wish to consolidate
- Photo ID
- Details of what the funds will be used for
How soon after a top up do I receive the funds?
Once approved, extra funds are typically released to your nominated account, though the timing depends on the lender and on whether a valuation is required. A top up that needs a physical valuation usually takes longer than one based on an automated check. If you have a firm deadline, such as a settlement date, tell us at the start. We can work out whether a top up is realistic or whether a faster private option makes more sense, and we will say so plainly.
Can I split a top up away from my main loan?
Often yes. Many lenders let you take extra funds as a separate loan split, with its own repayment type and term. That keeps the purpose of the money clear, which helps with record-keeping and with any tax questions. It can also let you pay the extra amount down faster without disturbing the main loan. Ask your lender, or ask us, what structures are available before you sign.

Frequently asked questions
What is a home loan top up?
It is an increase to the limit of your existing home loan, secured against the same property. Your lender reassesses your income, debts and the property's value, and if approved, the extra amount is released to you. It is a way to access equity without opening a separate mortgage.
How is a top up different from using redraw?
Redraw lets you access extra repayments you have already made. A top up increases the loan itself beyond what you have paid in. Redraw is typically quicker but limited to what you have paid ahead, while a top up can unlock equity that has built through property growth. Lenders treat the two differently.
Will my lender approve a top up?
It is not automatic. The lender will reassess your income, expenses, credit file and the property's value, as though it were a new application. Changes in your circumstances since you first borrowed, such as a lower income or new debts, can affect the outcome. We can look at alternatives if you are declined.
Can I top up my loan to consolidate debts?
Often yes, if the lender allows it and you meet its criteria. Rolling debts into a mortgage can reduce the number of repayments but spreads the debt over a longer term, so total interest paid may rise. We explain the trade-off clearly, not as personal advice, and compare other options.
Is the interest on a top up tax deductible?
It depends on what the money is used for, not on what secures the loan. For example, funds used for an investment may qualify, while funds used for private purposes do not. Keep clear records and check with your accountant or the ATO before assuming a deduction.
What if my current lender says no?
You still have choices. We may refinance to a lender with a more flexible policy, arrange a separate equity loan or look at a private second mortgage if timing or credit is the issue. Each has trade-offs, which we explain before you commit.
