Key Takeaways
- Borrowing against shares and borrowing against investment property equity can both provide capital without an immediate sale, but each uses different security and assessment rules.
- Share-backed facilities can respond directly to changes in portfolio value, including agreed loan-to-value limits and possible margin calls when security values fall.
- Property-backed borrowing depends on usable equity as well as serviceability, existing debt, valuation and the purpose of the proposed funds.
- Holding both shares and property does not mean both need to secure the same debt. The structure can affect liquidity, future borrowing and the consequences of falling asset values.
A substantial share portfolio and investment property can leave you asset-rich while much of that wealth remains tied up. To borrow against shares in Australia without selling them, you need to distinguish a share-backed facility from property-backed borrowing because each responds differently when values, income or debt change.
For borrowers whose wealth sits across several assets or entities, a broker for asset-rich borrowers may need to separate assessable income, security and ownership before an application is lodged.
Your share portfolio may secure a securities-backed facility, support your wider financial position or produce dividend income without securing the loan. An investment property may provide mortgage security and accessible equity, while a lender may still assess income, liabilities and other commitments before approving further credit.
Why Do Shares and Property Create Different Lending Paths?
Shares and property can affect a lending structure differently depending on whether the asset provides direct security, supports the wider application, produces assessable income or changes the regulatory treatment:
Shares Acting as Direct Security
Borrowing against shares means the securities themselves support the facility. Depending on the product terms, the borrower may retain ownership and market exposure while the provider obtains security rights over the portfolio.
A margin loan is one form of share-backed borrowing. Under a margin loan, the loan-to-value ratio (LVR) is tied to the value of the investments securing the facility. When those investments fall in value, the ratio rises even if the loan balance has not increased.
A fall in the pledged portfolio may affect the facility even while scheduled payments remain up to date because the shares form part of the provider’s security position.
Property Acting as Mortgage Security
Property-backed borrowing generally uses a mortgage over real property as security. The amount available may depend on the lender’s accepted property value, existing secured debt, the proposed loan and the lender’s credit policy.
Growth in property value can create equity, but the full increase is not automatically available as new borrowing. Refinancing or increasing a loan may require another assessment of the borrower’s financial position and proposed credit.
A property may therefore have substantial equity while equity release options remain constrained by serviceability, existing commitments or lender policy.
Other Assets Supporting the Application
Assets outside the security arrangement may still form part of a lender’s assessment of the borrower’s financial position.
A borrower might hold listed shares, cash and investment property while only one property secures the mortgage. The remaining assets may demonstrate liquidity or net worth without themselves becoming security for the loan.
Owning an asset does not automatically give the lender security rights over it or mean its full market value will be recognised.
Asset Income Supporting Serviceability
Income produced by an asset may contribute to serviceability even when the asset itself does not secure the loan, depending on lender policy and the evidence available.
Shares can produce dividends, while investment property can produce rent. Both income streams can change or stop, so lenders may assess them differently depending on the history, evidence and applicable credit policy.
Income, asset value and security play different roles in a lending assessment.
Loan Purpose Affecting Regulation
The product, borrower and purpose of the credit can determine which Australian regulatory framework applies.
A margin lending facility is a financial product under the Corporations Act 2001. Issuers and advisers of margin lending facilities need an Australian financial services (AFS) licence with the relevant authorisation and must comply with applicable licensing, conduct and disclosure requirements. The Australian Securities and Investments Commission (ASIC) sets out the margin lending requirements.
Consumer mortgage credit can instead fall under the National Consumer Credit Protection Act 2009 and the National Credit Code, depending on the borrower, purpose and other statutory criteria. The National Credit Code includes certain credit used to purchase, renovate or improve residential investment property.
Authorisation to engage in mortgage credit activities does not by itself provide the AFS licence authorisation required for margin lending. A structure involving both forms of finance may therefore involve different authorised professionals.
What Factors Shape a Share-Backed Facility?
A share-backed facility turns on the investments recognised under its terms and how the facility responds when values change. These factors are a general guide only because treatment varies by provider and product:
Portfolio Eligibility
The facility terms determine which investments can contribute to its recognised security value.
A margin loan can be used to invest in shares, exchange-traded funds and managed funds, but the investments accepted as security and the applicable lending terms depend on the particular facility.
The portfolio’s market value may therefore differ from the amount recognised for lending purposes.
Portfolio Concentration
A portfolio concentrated in one company can experience a larger overall movement when that holding rises or falls than a portfolio spread across several investments.
Diversification can reduce exposure to the fall of a single investment, while concentration can make the overall portfolio value move more sharply. How the provider treats that concentration depends on the facility terms.
Loan-to-Value Ratio
The loan-to-value ratio compares the amount borrowed with the value of the investments recognised under the facility.
Margin lenders require borrowers to keep the LVR below an agreed level. The ratio rises when recognised investments fall in value or the loan balance increases.
There is no single maximum LVR for every share-backed facility. Listed investments can change value quickly, so the security position may move without another drawdown.
Margin Thresholds
A margin call can occur when the LVR moves above the agreed level.
Depending on the facility terms, restoring the required position may involve paying money into the facility, adding eligible investments or selling investments to reduce the loan. If the required LVR is not restored, the provider may sell investments under the facility terms.
The required response and timeframe depend on the agreement, so the initial limit needs to be considered alongside the consequences of a fall in the portfolio.
Market Liquidity
Liquidity affects how readily an investment can be converted to cash if the borrower or provider needs to sell it.
A listed security may become harder to sell at its previous market value during sharp price movements, limited trading or a trading suspension. The effect on a particular share-backed facility depends on the securities involved and the agreement.
Limited liquidity may make it harder to raise cash when it is needed.
Facility Purpose
The permitted use of borrowed funds depends on the product terms and applicable regulatory framework.
Margin loans are commonly used to finance investments in shares, exchange-traded funds and managed funds. Other securities-backed arrangements may have different permitted purposes.
Borrowing to acquire more investments creates a different position from borrowing for another purpose and may affect tax treatment and the professional authorisation required.
Repayment Source
Borrowing against investments does not remove the obligation to repay the debt and interest under the facility terms.
The debt and interest remain payable even if the investment falls in value. Dividends may help with cash flow, but they can fall or stop. A future asset sale also creates timing risk if the asset is worth less or cannot be sold when expected.
What Factors Shape Property-Backed Borrowing?
Property-backed borrowing depends on recognised equity, repayment capacity, valuation, existing debt and the lender’s applicable credit settings. These factors are a general guide only because assessment methods vary by lender, product and borrower:
Available Equity
Equity is generally the value of the property less the amount owed against it.
The amount available for further borrowing can be lower once the lender applies its valuation, maximum LVR and credit policy.
A property worth $2 million with a $600,000 mortgage has $1.4 million of equity before considering the lender’s requirements, but that does not mean the full $1.4 million is available to borrow.
Where accessing equity involves replacing an existing loan, a refinance broker may need to assess the existing facility, proposed debt, fees and lender policy.
Serviceability Position
Property-backed borrowing typically requires the lender to assess whether the proposed repayments can be met under the rules and credit policy that apply to the loan.
For regulated consumer credit, credit licensees must make reasonable inquiries about the consumer’s financial situation and take reasonable steps to verify it before assessing whether the proposed credit is unsuitable.
For borrowers considering asset-rich lending options, substantial assets may still sit alongside relatively modest assessable income. Treatment of dividends, rent, business income and distributions varies by lender and evidence.
For residential mortgage lending by authorised deposit-taking institutions (ADIs), the Australian Prudential Regulation Authority (APRA) confirmed on 28 May 2026 that its mortgage serviceability buffer remains at a minimum of 3 percentage points.
Property Valuation
The lender’s accepted property value affects the amount of equity it recognises and the resulting LVR.
A valuation below the owner’s estimate can reduce the equity recognised for further borrowing. Valuation methods and lending treatment vary by lender and property.
Existing Debt
Existing debt can affect further borrowing because lenders may need to consider the borrower’s wider financial obligations.
For regulated consumer credit, the assessment includes inquiries into the consumer’s financial situation. Mortgages, personal loans, credit facilities and other debts may therefore affect the outcome.
Company or trust debt may also be relevant where guarantees, repayment obligations or the lender’s credit policy connect that debt to the borrower.
Debt-to-Income Position
Debt-to-income ratio (DTI) compares debt with income and is separate from the LVR used to assess debt against property value.
Effective from 1 February 2026, APRA requires ADIs to limit new residential mortgage lending at a DTI greater than or equal to 6 times income. An ADI may have up to 20% of new investment lending and up to 20% of new owner-occupied lending at or above that threshold, with the two portfolios measured separately.
The 20% setting is a portfolio limit for ADIs, not an automatic maximum DTI for every borrower. APRA confirmed on 28 May 2026 that these limits remained unchanged.
A borrower with substantial property equity may therefore still encounter lender constraints where total debt is high relative to income.
Loan Purpose
The intended use of released property equity may affect the credit assessment, documentation and tax treatment.
Funds for another property purchase can create a different lending position from funds for shares, business purposes or private expenses.
Where equity funds another property purchase, an investment loan broker may need to consider how the new debt interacts with existing investment lending.
For tax purposes, the Australian Taxation Office (ATO) generally looks at how borrowed money is used when considering whether interest is deductible. The property securing the loan does not by itself determine the tax treatment.
Security Structure
A property lending arrangement may involve one property or more than one property as security, depending on the lender and loan terms.
Where several properties support debt, selling or refinancing one may require the lender to reassess the remaining security before releasing its mortgage.
The consequences depend on the loan documents and lender policy. Separate security arrangements may provide different refinancing or sale options, depending on the borrower and lenders involved.
What Are the Differences Between Share-Backed and Property-Backed Loans?
The main differences concern how security values move, how the debt is assessed and what can happen when the underlying asset or the borrower’s financial position changes:
| Factor | Share-Backed Facility | Property-Backed Borrowing |
|---|---|---|
| Security value | Recognised investment value under the facility | Accepted property valuation |
| Primary assessment | Investment security, LVR and facility terms | Equity, financial position and property policy |
| Falling values | Can change the security position as market prices move | May reduce recognised equity after revaluation or sale |
| Security response | May require action after agreed thresholds are breached | Depends on the mortgage terms and applicable credit law |
| Documentation | Portfolio, ownership and facility evidence | Financial, liability, property and valuation evidence |
| Asset control | Subject to conditions over pledged investments | Subject to the mortgage and loan terms |
| Future borrowing | Debt and payments may affect later assessments | Debt may affect serviceability and available equity |
This table is a general guide only. The exact assessment, documentation and lender response depend on the facility terms, lender policy, borrower and security.
Security Values
Share-backed facilities can respond to market movements quickly because listed investments may change price throughout a trading day.
Property values also change, but residential mortgage security is not repriced against a live traded market. A lender may obtain a new valuation during a refinance, increase, sale or other security review.
A falling share market may therefore affect a margin-based security position before a property borrower seeks another credit decision.
Repayment Assessment
Both structures can involve an assessment of the borrower’s ability to meet financial obligations, although the legal requirements and provider processes differ.
Margin lending issuers are subject to responsible lending requirements under the Corporations Act. Regulated consumer mortgage credit is subject to responsible lending obligations under the National Consumer Credit Protection Act 2009.
A borrower who cannot obtain the desired property-backed amount cannot assume the same amount will be available against shares.
Forced Sale Exposure
A margin loan may lead to the sale of investments if falling values cause the LVR to breach the agreed level and the required position is not restored under the facility terms.
A mortgage does not generally respond to daily movements in property prices in the same way. Enforcement of regulated mortgage credit instead depends on the credit contract and applicable law.
Both structures can give the provider enforcement rights over security, but the triggers differ.
Asset Control
Security can affect how an asset is sold, transferred or replaced.
For share-backed borrowing, the applicable restrictions depend on the terms of the securities-backed facility. For mortgaged property, a sale generally requires the secured mortgage to be dealt with at settlement before clear title can pass to the buyer.
The practical effect depends on the specific loan and security documents.
Loan Terms
Share-backed and property-backed facilities may have different pricing, repayment periods, fees and review arrangements.
A property mortgage may have principal-and-interest or interest-only repayments, while a securities-backed facility may have different payment and review terms. Rates, fees, security requirements and repayment conditions depend on the product, so a headline rate alone may omit material differences.
Future Borrowing
Either form of debt may affect later borrowing because another lender may consider the outstanding balance and payment obligations in a future assessment.
Further mortgage debt can reduce unencumbered property equity. The effect of share-backed debt on a future mortgage application depends on how the next lender assesses the liability and associated investment income.
Using shares as security does not guarantee that future property borrowing capacity will remain unchanged.
Documentation Review
Share-backed borrowing and property-backed borrowing generally require evidence relevant to different forms of security.
A share-backed provider may require portfolio and ownership information under its application process. A property lender may require evidence of the borrower’s financial position, existing liabilities, property details and an accepted valuation.
Company or trust ownership can add entity and guarantee documents. Requirements depend on the provider, borrower, ownership structure and facility.
What Issues Arise When Property Equity Funds Share Investment?
Using property-backed debt to buy shares leaves the property debt outstanding while the purchased investments remain exposed to market movements. Further margin borrowing against those shares can add a second layer of debt:
Double-Gearing Exposure
Double gearing can occur where money is borrowed against another asset, such as property, to buy shares and those shares are then used to support a margin loan for additional investment.
A fall in the shares does not reduce the property-backed debt used to acquire them. If the shares also secure a margin loan, the same fall may increase that facility’s LVR and create a margin call.
Both debts can remain outstanding after the investment value falls.
Margin Call Pressure
A margin call may require the borrower to reduce the loan, contribute money or add investments accepted under the facility.
If the agreed LVR is not restored, the provider may sell investments under the facility terms.
Property equity elsewhere does not guarantee immediate access to cash. Further property-backed borrowing may require another assessment and valuation, while serviceability, existing debt and lender policy may limit the amount available.
Mortgage Repayment Commitments
Property-backed debt remains payable according to the credit contract even when investments bought with the borrowed money fall in value.
A $200,000 property-backed advance does not fall to $160,000 merely because the investments bought with those funds are now worth $160,000.
Dividends, rent or other cash flow may assist with repayments, but those income sources can change.
Tax Treatment
Tax treatment depends on the facts of the transaction, including how borrowed funds are used.
ATO guidance provides that interest on money borrowed to buy shares or related investments may be deductible where the investments produce assessable income. Where borrowed money is used partly for private purposes, interest generally needs to be apportioned.
A redraw used for a different purpose can create mixed-purpose debt requiring ongoing interest apportionment. The tax outcome depends on the transaction and ownership arrangements, so individual tax advice may be needed.
Regulatory Boundaries
Mortgage credit and margin lending can involve different licensing frameworks.
A credit licensee or credit representative may be authorised to provide credit assistance for regulated mortgage credit without holding the AFS licence authorisation required to advise on margin lending.
A financial adviser or securities provider may hold relevant financial services authorisations without providing mortgage credit assistance. A wider strategy may therefore involve different authorised professionals.
Liquidity Pressure
Property-backed and securities-backed facilities can create cash demands on different timelines.
A margin facility may require action when its agreed LVR is breached, while increasing property debt generally requires a separate credit process.
A planned property sale can take time, while selling shares during a market fall may realise less cash than expected. Liquidity therefore matters separately from total asset value.
How Does the Wider Financial Position Affect Security Choice?
The security decision sits within the borrower’s wider position, so funding purpose, cash flow, market exposure, existing debt, ownership and the repayment plan can all affect how the structure operates:
Funding Purpose Shaping Loan Term
The purpose of the borrowing can affect which product and loan term are relevant.
Short-term funding may place more weight on establishment costs, repayment timing and the planned exit. Longer-term debt needs to remain manageable if rates, income or asset values change.
Property-backed funds used for another property transaction can therefore create a different position from property debt used to acquire shares.
Cash Flow Supporting Repayment Capacity
Cash flow affects how ongoing debt obligations are met even where the borrower holds substantial assets.
Depending on the facility and lender, assessable cash flow may include salary, business income, rent, dividends or distributions, all of which can change.
Expected capital growth also does not provide cash for repayments unless the asset is sold or another source of funds becomes available.
Market Risk Testing Available Liquidity
Accessible liquidity is separate from total net worth.
Cash and readily tradable assets can provide more options during an unexpected cash requirement than wealth concentrated in less liquid assets.
Share-backed borrowing can react directly to changes in investment values. Additional property-backed borrowing may require another credit assessment and valuation.
Liquidity can therefore matter where the borrower intends to retain both asset classes during weaker market conditions.
Existing Property Debt Limiting Flexibility
Existing property debt can reduce the equity available for another purpose and may add to the repayment commitments considered in a further application.
An investment property may already support another facility or broader security arrangement. Fixed-rate periods, guarantees and other loan conditions may affect refinancing or restructuring.
Using additional equity can reduce the amount remaining for another purchase, business need or future refinance.
Ownership Structure Affecting Borrowing
Legal ownership can affect who borrows, who provides security and which documents a lender requires.
Shares may be held personally, through a company or through a trust. An investment property may be held through a different entity.
Where property is held through one of these entities, a broker for complex structures may need to review entity documents, financial information, guarantees and related liabilities, depending on the lender.
Moving borrowed funds between entities may also have tax, accounting or legal consequences requiring separate professional consideration.
Exit Planning Covering Repayment Delays
An exit plan identifies the expected repayment source and what could happen if that source is delayed or produces less cash than expected.
Long-term mortgage debt may be repaid progressively from income. A shorter facility may depend on a property sale, share sale, refinance or another liquidity event.
A delayed property sale can extend holding costs, a falling market can reduce share-sale proceeds and a future refinance remains subject to the borrower’s circumstances and lender policy. A contingency can provide capacity if the expected repayment event is delayed or falls short.
Clearer Choice Between Shares and Property
You do not need to treat every asset on the balance sheet as interchangeable security. Once the funding purpose, repayment source and exposure to value changes are clear, you can assess whether property-backed borrowing belongs in the structure without assuming the share portfolio must be sold or pledged.

Frequently Asked Questions (FAQs)
1. Can one loan use both shares and investment property as security?
Potentially, depending on the lender, product, ownership structure and facility terms.
Property lending and securities-backed lending sit under different product and regulatory frameworks, so the assets do not automatically form one pool of security. Where more than one asset supports borrowing, the facility documents determine what is secured and what is required to release, sell or refinance it.
2. Does borrowing against shares trigger capital gains tax?
Taking a loan secured against shares does not generally amount to a disposal of those shares if ownership does not change merely because the security is granted.
A capital gains tax (CGT) event may occur when an asset is disposed of, including when shares are sold. A later sale of pledged shares, including under enforcement rights, may therefore have CGT consequences depending on the investor and transaction.
Different arrangements can have different tax consequences, particularly where ownership or beneficial interests change. A qualified tax professional can assess the specific structure.
3. Can share-backed funds be used as a property deposit?
Possibly, if the share-backed facility permits that use and the property lender accepts the wider borrowing position.
The property lender may assess the source of the deposit, the related debt and its repayment obligations. The securities-backed provider’s terms also determine whether the proposed use is permitted.
Using borrowed funds for the deposit does not remove the associated liability from the borrower’s overall financial position.
