A cash-out refinance replaces your home loan with a larger loan and pays you the surplus after the existing debt and settlement costs are covered. The lender reassesses the full new balance and applies its cash-out rules to your purpose. Your home secures the extra borrowing, so a lower interest rate does not remove the repayment risk.
How a Cash-Out Refinance Works
A cash-out refinance creates a new credit contract that pays out the existing mortgage and releases the remaining funds. In an illustrative example, a $450,000 replacement loan pays out a $400,000 mortgage and leaves $50,000 before fees. If you finance settlement costs within the $450,000 limit, the cash you receive falls by those costs.
An ordinary mortgage refinance switches the loan without taking extra funds. Redraw lets you borrow back extra repayments under an existing facility, subject to its terms. The United States VA cash-out product is a separate veterans’ lending programme. Its eligibility rules do not apply to Australian home loans.
How Much Equity You Can Access
Your accessible equity depends on the lender’s valuation and maximum loan-to-value ratio (LVR) for your purpose, less the existing balance. Total equity is the property value less the loan balance. Usable equity is the portion a lender will let you borrow against after its LVR limit and credit assessment.
Suppose the lender values your home at $600,000 and you owe $400,000. You have $200,000 of total equity. At an illustrative 80% maximum LVR, the lender’s total loan limit is $480,000. That leaves $80,000 of potential extra borrowing before fees, subject to affordability and cash-out policy.
The $450,000 replacement loan in the earlier example has a 75% LVR against that $600,000 valuation. A lower valuation reduces the amount available. Use the LVR calculation with the lender’s accepted value, including any costs added to the loan.
Equity alone does not establish approval. The lender reassesses income, living expenses and debts against the whole new loan. Unused credit card limits also affect borrowing capacity because the borrower can draw on them. Include those limits in the application even when the cards have a zero balance.
Purpose Rules and Lender Differences
Lenders require a declared purpose for cash-out and set their own amount, LVR and evidence rules. A purpose statement explains where the money will go. Larger requests can require invoices, renovation quotes or other documents, depending on the lender and proposed use.
Two published policies show why an 80% rule cannot describe the whole market.
- Macquarie’s residential credit guidelines require purpose details from the borrower discussion. Up to 80% LVR, the guidelines set no separate cash-out amount limit, subject to credit assessment. Above 80% LVR, cash-out, equity release and debt consolidation are prohibited beyond a $5,000 allowance for costs.
- AMP Bank’s cash-out policy permits up to $500,000 without documentary evidence of use, provided the purpose is declared and negative gearing is unnecessary for servicing. Its maximum is 90% LVR, excluding lenders mortgage insurance (LMI) for principal-and-interest loans and including LMI for interest-only loans. Above $500,000 and up to $1 million, AMP requires a statutory declaration and supporting documents where available. At a base LVR above 85%, the cash-out component is capped at 20% of the security value.
These are lender-specific examples, and the purpose must still meet each lender’s policy. Macquarie, for example, excludes cash-out to maintain lifestyle or meet existing repayments. A declared purpose does not make every use acceptable.
Some lenders allow a further advance under the existing facility. Others require a replacement loan for the requested amount or product. Increasing the existing loan with the current lender is a home loan top-up, and separate equity structures are covered in the home equity guide.
Cash-Out Purpose Record
Copy this record for the application and repeat the item fields for each use of the funds. Leave unconfirmed facts blank and record what still needs the client’s answer.
Requested cash-out funds (after financed costs): $ Financed settlement costs, if any: $ Use of funds (repeat for each item) Purpose: Amount: $ Supporting evidence: Recipient and payment route, if known: Client confirmation: Total itemised uses: $ Difference from requested cash-out funds: $ Unresolved items and person responsible for follow-up: Client confirmation of the full record: Confirmation date:
The itemised total must equal the requested cash-out funds. Resolve any difference before lodging and keep financed costs separate to avoid counting them twice. Obtain the client’s confirmation before recording a proposed use as their stated purpose.
Compare the rate and fees on the whole replacement balance. A discount on the extra $50,000 can be outweighed by a higher rate on the existing $400,000. Keep the remaining term in the comparison so the refinance does not appear cheaper solely because repayment takes longer.
Common Uses and the Real Cost
Cash-out commonly funds renovations, a car, a deposit for another property or the payout of other debts. A deposit for an investment property still leaves you with the larger first mortgage and the new property’s borrowing. Assess both repayments together.
A car bought with cash-out becomes part of the mortgage debt. Plan to repay that portion within the years you expect to keep the car, or the interest can outlast the vehicle. A refinance can also pay out a former partner’s share after separation. That ownership change is a transfer of equity, and the remaining borrower must qualify for the whole new loan alone.
Debt consolidation can reduce the monthly payment while increasing total interest if repayment is stretched over the mortgage term. The following illustrative calculation isolates $20,000 of debt. It assumes fixed rates, monthly principal-and-interest repayments and no fees or extra repayments.
| Debt arrangement | Annual rate | Repayment term | Monthly repayment | Total interest |
|---|---|---|---|---|
| Separate personal loan | 12% | 5 years | About $445 | About $6,693 |
| Amount added to home loan | 6% | 25 years | About $129 | About $18,658 |
The lower-rate option costs about $11,965 more in interest in this example because it runs for 20 extra years. Repaying the added debt over five years would change the result. Moneysmart’s debt consolidation guidance also warns that a longer term can increase interest and that securing debt against your home puts it at risk.
Include establishment fees, valuation costs and the old lender’s discharge charge in the refinance calculation. A fixed-rate loan can also have break costs. Where LMI applies, include it in both the cash required and the balance used for the LVR calculation.
A formal application creates a credit enquiry, which can affect your credit score. Compare the full loan cost over your expected holding period and over its full term. If a fresh 30-year term replaces a loan with 20 years remaining, show the cost of that extension alongside the lower monthly payment.
When It Fits and When It Does Not
A cash-out refinance can fit when income is stable, usable equity covers the request and the expense would otherwise require dearer finance. The new loan must remain affordable after fees and any change to the existing mortgage rate. A documented expense and repayment plan make that comparison possible.
Avoid increasing the mortgage when you already struggle with its current repayment or depend on an uncertain future sale to clear the new debt. Home equity does not provide income for the monthly payment. Borrowing against it can increase the loss if the property must be sold.
Test the new repayment at a higher interest rate and with room for irregular expenses. For illustration, a $450,000 loan over 25 years costs about $2,899 a month at 6%, compared with $3,473 at 8%. These figures exclude fees and assume monthly principal-and-interest repayments at constant rates. The roughly $574 monthly increase must fit your budget without relying on a future rate cut.
Tax Tracing When the Funds Are Invested
Interest deductibility depends on how the borrowed funds are used, including whether that use produces assessable income. The property securing the loan does not determine the deduction by itself. Keep bank transfers, purchase records and invoices showing where investment funds went.
ATO Taxation Ruling TR 2000/2 treats redraws of extra repayments as new borrowings. The interest treatment follows the use of those redrawn funds. Redrawing an investment loan to pay a private expense therefore does not preserve deductibility merely because the original loan funded an investment.
Using one loan for private spending and investment can require interest apportionment and ongoing records. Before releasing investment funds, take the proposed structure and intended payments to a registered tax agent. The agent can assess deductibility for your circumstances and explain the records to keep.
Alternatives to Compare Before You Lodge
Compare cash-out refinancing with options that fund the expense while keeping the current mortgage in place. Use the same amount and repayment horizon for each option, then include fees and any change in interest on the existing balance.
| Option | Cost and repayment term | Effect on the existing mortgage |
|---|---|---|
| Personal loan | An unsecured loan can have a higher rate but a shorter repayment term. Compare total interest and fees. | A separate repayment leaves the existing mortgage contract in place. |
| Further advance or top-up | Additional home lending depends on the lender’s assessment, rate and fees. Set a repayment term for the extra debt. | Increases borrowing with the current lender. Confirm whether existing pricing or terms change. |
| Line of credit | Interest generally applies to drawn funds. Ongoing access requires repayment discipline, and the facility can have its own rate and fees. | A separate equity facility can retain the original loan, subject to the lender’s security requirements. |
| Offset withdrawal | Uses your own cash. With less money offsetting the loan, mortgage interest increases. | The loan balance and contract remain in place. Your cash buffer falls. |
| Redraw | Uses available extra repayments under the lender’s redraw terms. The amount withdrawn increases the outstanding debt and future interest. | The existing facility remains. A different use of redrawn funds can change the tax treatment. |
Before lodging, record the purpose, amount requested and resulting LVR. Name the alternative rejected and explain why the replacement loan suits the expense better. Keep the repayment comparison and supporting purpose documents with that record.
