Cross-collateralised loans use two or more properties as security for the same lending arrangement. Each property backs the combined debt, so selling or refinancing one property requires the lender to agree to release its security.
Existing equity can help fund another purchase without saving a separate cash deposit. The trade-off is that your home and investment property can both support debt used to buy the investment.
What Cross-Collateralisation Means in Practice
Cross-collateralisation means the lender takes security over each property in a pool. The lender’s recovery position rests on both properties if the borrower defaults, even when separate loan accounts show different balances.
Consider a hypothetical home worth $900,000 and an investment property worth $500,000. Together they provide $1.4 million of security. If the combined debt is $1 million, the loan-to-value ratio (LVR) is about 71.4%: $1 million divided by $1.4 million, multiplied by 100.
The lender can structure this as one facility with internal splits for different loan purposes. A split labelled with a property address does not establish that only that property secures it. The mortgage documents define which properties back which debts.
Lenders and brokers often market a multi-property facility as a portfolio loan. Policies on property counts, acceptable property types and split structures change. Match the proposed security structure to the lender’s policy and offer documents before signing.
The Advantages Brokers Can Cite
Pooled equity can fund another purchase without waiting to save a separate cash deposit. Approval still depends on sufficient usable equity and income to repay the combined debt. Purchase costs also need funding.
One lender can simplify administration because the loans sit with one institution. Bundled pricing or fee waivers can reduce costs, but compare the written offer with the same borrowing on standalone security. Include the cost of selling or refinancing one property in that comparison.
The Risks to Price in Before Signing
A fall in one property’s value reduces equity across the pool. Using the hypothetical $1 million debt and $1.4 million security pool, a $100,000 fall in either property lifts the combined LVR to about 76.9%. The debt stays the same while the security value falls to $1.3 million.
Selling one property requires the lender’s consent to a partial discharge. The lender assesses the security that remains and can require debt reduction or changes to the remaining loan splits. The amount owed on the split labelled for the sold property does not, by itself, set the release amount.
For example, Macquarie’s partial-discharge guidance requires a credit assessment. Macquarie sets the required paydown and says some borrowers must apply all net sale proceeds to the loan. Its request also asks for estimated values of the properties retained.
ANZ’s consumer lending terms allow a valuation administration fee for a partial-discharge request. These are lender-specific examples. They do not establish a universal release formula or mean every release requires a new valuation.
Above 80% LVR, lenders mortgage insurance (LMI) may apply, subject to the lender’s requirements and any applicable exemption. Helia explains that LMI supports borrowing with less than a 20% deposit and protects the lender against a shortfall after default. A higher pooled LVR can therefore affect both borrowing options and costs.
How Borrowers Qualify
Borrowers qualify on the combined exposure: the lender assesses total debt repayments as well as the security pool. Sufficient equity cannot compensate for income that fails the lender’s serviceability assessment.
Prepare income evidence and details of existing debts, living expenses and rental income. The lender also assesses credit history. Obtain lender-accepted valuations on every property in the pool so the application uses the lender’s security values.
Understanding what lenders look for helps you prepare the application. Document an exit plan for each property, including which debt would remain after a sale and how it would be supported. A lower valuation can change the proposed structure before approval.
Alternatives to Compare First
Standalone security keeps each loan secured by its own property. It can make a later sale or refinance easier because the other property does not secure that loan. Review the actual mortgage terms when comparing structures.
You can also borrow the deposit gap against one existing property and take a separate loan secured only by the new purchase. The guide to using existing equity as a deposit explains that approach. Drawing equity and pooling security are separate decisions.
For example, a separate equity-release split secured only by your existing home can fund the deposit. A second loan secured only by the new property funds the balance. The home still backs the equity-release debt, but the new property does not secure that split.
On a later sale of the new property, its lender releases that property’s mortgage after its payout requirements are met. The separate home-secured split remains. With cross-securitisation, the lender instead reviews the remaining security pool before deciding the sale’s required paydown.
Facilities across two lenders are another option. Each lender must approve its own loan and assess your other commitments. Compare full lifecycle costs, including establishment and ongoing fees, interest, discharge charges and any fixed-rate break costs. A cheaper starting rate can lose its advantage when one property needs to leave the pool.
Reviewing an Existing Cross-Collateralised Loan
Review an existing cross-collateralised loan by mapping each property to every debt it secures. Obtain current balances and lender-accepted property values, then model a sale or refinance of each property separately.
- Ask the lender in writing, “What repayment, valuations, fees and changes to the remaining accounts would you require to release this property?” Obtain the release conditions before relying on sale proceeds for another purchase.
- Test a 10% to 20% fall in the pool’s value while holding debt unchanged. In the hypothetical example, a 10% fall leaves $1.26 million of security and about 79.4% LVR. A 20% fall leaves $1.12 million and about 89.3% LVR.
- Price the same borrowing on standalone security beside the existing arrangement. Include restructuring costs and compare the period you expect to hold each property.
Before signing a new facility or changing an existing one, use the written release terms to decide whether pooled security suits your planned exits. Confirm the debt allocation and available sale proceeds for each exit with the lender before committing to the next transaction.
