A home loan top-up increases borrowing with the current lender, subject to approval of the extra debt and its purpose. As the broker, compare a variation with a separate split and refinancing before recommending the structure. Keeping the same lender does not guarantee a faster approval or a lower total cost.
Compare the Available Structures
Start with the amount your client needs, what they will spend it on and the repayment period that suits that expense. Compare the cost of the available structures over the same period. Include interest on the existing balance, fees and any cost of ending a fixed rate.
| Structure | What changes | What to compare |
|---|---|---|
| Top-up of the existing facility | The current lender increases an existing loan limit. | The rate and repayments after the increase, remaining term and variation fees. |
| New split with the current lender | Additional borrowing has a separate account or loan component. | Its rate, term and repayment type, plus the terms retained on the original debt. |
| Internal refinance | The current lender replaces or restructures existing borrowing. | The replacement terms, costs and account changes, including whether existing discounts survive. |
| External refinance with extra funds | A new lender pays out existing debt and lends the additional amount. | Discharge and establishment costs, fixed-rate break costs and the total repayment outcome. |
Use the lender policy guides to confirm the permitted structure for the lender and product.
A lower interest rate on additional funds can still produce more interest if a short-term expense is repaid over the full mortgage term. Compare a shorter repayment period for that portion. A separate split can make the intended repayments easier to track, where the lender permits it.
Westpac’s cash-out assessment distinguishes purpose and mortgage-insurance status. Use the Westpac lender guide for its conditions.
A top-up keeps the borrowing with the current lender, while a cash-out refinance moves the debt and additional funds to another lender. Other home equity structures can separate borrowing or provide different access to funds. Choose the structure that fits the client’s purpose and total cost.
Check Equity and Reassessment
Record all debt secured by the property and calculate the proposed loan-to-value ratio (LVR) using the lender’s accepted valuation. Keep the current balance and current limit separate. Available redraw or an undrawn split can make those figures different.
For a hypothetical application, an existing $480,000 limit plus a $60,000 increase produces $540,000 of total limits. Against an accepted $750,000 valuation, the resulting LVR is 72%. If the existing balance is only $450,000, using it would understate the total limits in this example. Follow the lender’s definition of exposure and include financed costs where its calculation requires them.
Equity establishes security coverage. The lender must also assess whether the client can repay the proposed debt. Confirm the required income evidence and update existing commitments, living expenses and repayment history. Use the assessment method that applies to the actual variation, including any change of term or repayment type.
Check whether the increase needs lenders mortgage insurance (LMI), an insurer approval or a further premium. Existing insurance does not itself approve additional borrowing. Record the valuation method and any conditions affecting the amount the client can access. The serviceability guide explains the broader repayment-capacity assessment.
Evidence the Cash-Out Purpose
Match the supporting documents to the actual use of the additional funds. A statement that the client wants access to equity does not explain what the money will fund.
| Purpose | Evidence to prepare | Submission detail |
|---|---|---|
| Renovation | Quotes, work scope and a building contract where applicable. | Separate repairs from structural work and identify whether progress payments or further valuations are required. |
| Debt consolidation | Statements identifying the creditors and payout amounts. | State which accounts will be paid out and which limits will be closed or reduced. |
| Property purchase deposit | The proposed purchase details and contract when available. | Show the deposit amount and how the remaining purchase costs will be funded. |
| Other personal or investment spending | Documents supporting the stated expense or proposed investment. | Reconcile each purpose amount to the total request and identify the intended recipient. |
Large cash-out requests can trigger more evidence, a lower permitted LVR or a different release process. Mortgage insurance and construction work can also change the applicable conditions. Apply the cash-out policy for the proposed structure before telling the client that funds will be unrestricted. Westpac’s broker policy summary illustrates these purpose-dependent conditions.
A self-managed super fund (SMSF) requires a separate borrowing assessment. New limited recourse borrowing arrangements (LRBAs) for real property are restricted to business real property. Existing arrangements have transitional protection, so establish whether the proposed change creates a new arrangement before proceeding. The Mortgage and Finance Association of Australia’s explanation of SMSF borrowing changes links to the ATO’s eligibility guidance.
Borrowed money under an LRBA cannot fund improvements. Permitted repairs or maintenance and improvements require different treatment, and work must preserve the asset allowed under the arrangement. The Auditing and Assurance Standards Board’s SMSF guidance explains these restrictions. Refer an SMSF renovation request to qualified SMSF advisers and legal specialists before treating it as an ordinary residential top-up.
Prepare the Variation Submission
Submit the permitted structure with evidence that reconciles to the requested limit and purpose. Use the lender’s variation process and retain the written response to any exception request.
- Confirm the structure. Identify whether the lender accepts an increase to the existing facility or requires a separate split or replacement loan.
- Record the client’s instructions. State the additional amount, purpose and preferred repayment period, including terms they want to retain.
- Complete the assessment. Collect the required financial documents and valuation, then reconcile all purpose amounts and financed costs to the proposed limits.
- Lodge the application. Include existing account references, proposed split details and disbursement instructions with the supporting documents.
- Respond to conditions. Explain any revised amount or structure to the client and obtain updated instructions before accepting a different outcome.
- Arrange completion. Confirm the signed documents and outstanding conditions, then identify when the lender will make funds available.
Home loan top-up processing time depends on the assessment queue and the work required after it. A valuation, missing documents or an exception can delay credit approval. Signing, insurer conditions and the lender’s funds-release process add time after approval.
Use the lender’s service levels for the relevant application type when discussing timing. NAB’s broker service levels identify a queue for refinances, limit increases and variations. An assessment pickup time does not promise completion or funds release. Give the client the remaining stages and revise the estimate when a condition changes.
Check Broker Remuneration on the Increase
Confirm commission from the lender’s remuneration schedule and your aggregator agreement for the exact transaction. A consumer top-up page does not establish the broker’s entitlement. An increase to existing debt and a replacement facility can have different payment treatment.
Record whether upfront applies to additional funds, a replacement balance or neither. Identify the eligible balance basis, any drawdown requirement and the payment timing. Check minimum amounts or exclusions where the agreement includes them. Confirm the aggregator’s deductions and tax treatment before calculating your expected payment.
Map the original account to the increased facility and each new split. Retain the application reference, completion event and old-to-new account references beside the documented entitlement. A new account number alone does not establish a new commissionable settlement.
Check whether replacing or reducing the original account affects its existing upfront payment. Apply the agreement’s treatment of internal changes and any relevant commission clawback rules. Keep the client’s loan recommendation based on their needs and costs, separately from the brokerage’s payment expectation.
Verify the Completed Loan Change
Compare the completed facility with the client’s instructions before closing the variation file. Check the approved purpose and total limit, then confirm the amount drawn and where the funds went. Verify each split’s rate, repayment type and term against the accepted offer.
For the hypothetical $60,000 increase, a partial draw of $40,000 leaves a different drawn balance from the approved limit. Keep both figures in the completion record. Use the balance basis specified in the remuneration agreement when checking commission.
Compare the next commission statement with the documented entitlement and account mapping. If the original account disappears, establish whether it was replaced or discharged. Where old and new references both receive trail, reconcile them to the actual facilities before labelling the payments duplicates. For missing trail, check the statement period and first-payment timing before raising a discrepancy.
Track My Trail’s Quick Analysis compares two monthly reports and shows large drawdowns, added loans and loans that dropped off. Use those changes alongside the account mapping to investigate the variation’s effect on trail.
Send the aggregator a discrepancy supported by the affected account references and the relevant statement rows. Include the completion details and the agreement clause used for your expected payment. Keep the item open until the statement correction or written payment explanation reconciles to the completed loan change.
