What Is Cross-Collateralisation? Risks & Benefits
What Is Cross-Collateralisation?
When you already own a property and want to purchase another, the equity in your existing property may help you fund the next purchase. However, the way the loans and properties are connected can have a major impact on your future flexibility.
One structure a lender may propose is cross-collateralisation. This can simplify the initial purchase, but it can also give the lender security over multiple properties and make it more difficult to sell, refinance or restructure one property independently.
Understanding how cross-collateralisation works before accepting a loan structure can help you make a more informed decision and avoid unnecessary complications later.
What Does Cross-Collateralisation Mean?
Cross-collateralisation occurs when a lender uses more than one property as security for one or more loans.
For example, you may already own your home and use the available equity to purchase an investment property. Under a cross-collateralised structure, the lender may hold both your home and the investment property as security for the lending arrangement.
Rather than each property standing behind its own loan, the properties and debts become linked within the lender’s security structure.
This does not mean the properties are combined or that their ownership changes. It means the lender may rely on both properties as security if the loan obligations are not met.
How Does Cross-Collateralisation Work?
Suppose you have:
A home valued at $800,000
An existing home loan balance of $400,000
A new investment property purchase price of $600,000
Your existing home has $400,000 in total equity. However, total equity and usable equity are not necessarily the same. Lenders commonly assess usable equity by applying a maximum acceptable loan-to-value ratio and subtracting the debt already secured against the property.
If the lender uses both your existing home and the new investment property as security, the arrangement may look broadly like this:
Security held by the lender | Lending connected to the security |
|---|---|
Existing home | Existing home loan and lending used for the new purchase |
New investment property | New investment loan and potentially the broader lending arrangement |
The exact loan accounts may still appear separately in your online banking. The important issue is not simply how many loan accounts exist, but which properties legally secure each debt.
Why Do Lenders Use Cross-Collateralisation?
Cross-collateralisation can provide the lender with a stronger overall security position. If one property falls in value or is sold, the lender can consider the combined value of the properties and the total debt it holds.
It may also make the initial transaction appear simpler because the same lender controls the existing property, its available equity and the finance for the new purchase.
However, a structure that is convenient at settlement may not provide the greatest flexibility over the longer term.
What Are the Potential Benefits?
Cross-collateralisation is not automatically unsuitable. Depending on the borrower, lender and transaction, possible benefits may include:
Using existing equity towards another purchase
The structure may allow you to use equity in an existing property towards the deposit and purchasing costs for another property, subject to valuation, serviceability and lending criteria.
A simpler arrangement with one lender
Keeping the loans and securities with one lender may reduce the number of institutions involved in the transaction. This can make applications, valuations and settlement coordination more straightforward in some circumstances.
Potentially reducing the need for a cash contribution
Where sufficient usable equity is available, the lender may allow that equity to support part of the new purchase. This may reduce the amount of cash required, although costs, loan-to-value ratio limits and lender requirements still need to be considered.
Consolidated loan management
Some borrowers prefer managing their property lending through one lender and online banking platform. Convenience, however, should be weighed against the level of control you may give up.
What Are the Risks of Cross-Collateralisation?
The main concern is that linking multiple properties can reduce your ability to make changes to one property or loan independently.
Selling one property can become more complicated
If you decide to sell one of the properties, the lender must agree to release that property from its security.
The lender may review:
The remaining property value
The total debt that will remain
Your current income and expenses
Your repayment history
The resulting loan-to-value ratio
Its lending policy at that time
The lender may also require some of the sale proceeds to reduce another loan before releasing the property. This could limit how much money you retain from the sale for your next purchase or other plans.
Refinancing may be less flexible
You may want to move one loan to another lender because of a more suitable interest rate, product or feature. If the properties are cross-collateralised, refinancing only one part of the arrangement can be more complex.
The existing lender may need to release a property, while the new lender completes its own valuation and assessment. In some cases, restructuring or refinancing more of the lending may be required.
One lender controls the broader security position
When the same lender holds multiple properties as security, it has greater control over requests to sell, refinance, access equity or change the loan structure.
You may be comfortable with the lender today, but its policies, products, pricing and assessment requirements may change over time.
A lower valuation can affect the wider arrangement
Property valuations are completed for the lender’s purposes and may be lower than an owner or selling agent expects.
If one property receives a lower valuation, the lender may assess the combined security position differently. This could affect your ability to release a property, access further equity or restructure the loans.
Your properties may be exposed to the same lending relationship
Because multiple properties support the lending, financial difficulty affecting one loan can place the broader secured position at risk. If repayments are not maintained, the lender’s rights may extend to more than one property, subject to the loan and security documents.
Loan and tax administration can become more complex
The security for a loan and the purpose of the borrowed money are separate issues. Cross-collateralisation does not determine whether interest is tax deductible.
Where lending includes both private and investment purposes, careful loan splitting and record-keeping may be important. Obtain advice from a registered tax agent about deductibility and from a solicitor or conveyancer about the legal effect of the security documents.
What Happens If You Want to Sell One Property?
Selling a cross-collateralised property is not necessarily impossible, but the process generally involves more than repaying the loan account you associate with that property.
The lender will usually assess whether the remaining property or properties provide sufficient security for the remaining debt. Depending on the outcome, it may:
Release the property without requiring additional debt reduction
Require part of the sale proceeds to repay or reduce one or more loans
Request updated valuations of the remaining properties
Reassess your financial position
Require another property or acceptable asset to be offered as replacement security
Decline to release the property unless the lending is restructured
It is important to speak with your mortgage broker, lender and conveyancer before committing the expected sale proceeds to another purchase.
Does Cross-Collateralisation Affect Borrowing Power?
Cross-collateralisation does not automatically change your income, expenses or existing debt, which are key parts of a borrowing power assessment.
However, the structure may affect how easily you can access equity, release a property or move part of your lending to another lender. This can influence the options available when you apply for further finance.
Every lender applies its own assessment criteria, including how it treats existing debts, rental income, living expenses, loan limits and property valuations. A structure accepted by one lender may not be viewed in the same way by another.
What Is the Alternative to Cross-Collateralisation?
One alternative may be to keep each property and its lending separately secured.
For example:
A separate equity loan split may be established against the existing property to contribute towards the deposit and eligible purchasing costs.
The main loan for the new purchase may be secured only by the new property.
Under this type of structure, the lender for the new property does not necessarily need to hold the existing property as additional security. Depending on the circumstances, the two properties may even be financed by different lenders.
Cross-collateralised structure | Separately secured structure |
Multiple properties may secure the lending | Each property generally secures its relevant loan or loan splits |
One lender usually controls the combined security position | It may be easier to deal with each property independently |
Selling or refinancing one property may trigger a broader review | Selling or refinancing may be more straightforward, subject to lender requirements |
Equity and debts can become closely linked | Loan purposes and property securities may be easier to identify |
A separately secured structure is not automatically available or suitable. The outcome depends on usable equity, borrowing capacity, loan-to-value ratios, lender policy, costs and the purpose of each loan split.
How Can You Tell Whether Your Properties Are Cross-Collateralised?
Do not rely only on the names or balances shown in online banking. Review the loan approval, mortgage and security documents to identify which property secures each loan.
You can also ask your lender or mortgage broker:
Which property secures each loan account?
Does either property secure more than one loan?
Will the new property also secure my existing home loan?
What would be required to sell or refinance one property?
Could the lender require sale proceeds to reduce another loan?
Can the lending be structured with separate securities instead?
For legal confirmation about the lender’s rights under the documents, speak with a qualified solicitor or conveyancer.
Is Cross-Collateralisation a Bad Idea?
Not necessarily. The right structure depends on your financial position, the available equity, the properties involved and your future plans.
Cross-collateralisation may be workable where you understand the arrangement, prefer to remain with one lender and do not expect to sell or refinance the properties separately.
It may be less appealing if you value flexibility, plan to build a larger property portfolio, expect to sell one property, want to use different lenders or would prefer each loan and security to remain clearly separated.
The key is to assess the structure based on more than whether the lender will approve the immediate purchase.
