Usable-equity estimate
A common starting calculation is the chosen percentage of the lender valuation, less debt already secured by that property. The lender may use a lower valuation or LVR.

Turn usable equity into a clearly structured investment deposit
Equity can help fund an investment deposit and purchase costs, but available equity is not the same as total equity. The valuation, LVR, serviceability and loan structure all need to work together.
Equity and investment-loan planning
The short answer
How can home equity be used to buy an investment property?
A lender may allow a separate loan or split secured by an existing property to fund some or all of the investment deposit and eligible costs. The remaining purchase loan is commonly secured by the new property. Approval depends on valuations, acceptable LVRs, borrowing capacity and the purpose of each advance.
Model before you commit
Equity is security—not additional income
A strong property value may provide deposit security, but the borrower still needs sufficient income and cash flow to service the total debt under lender assessment rules.
- Use lender-supported valuations rather than optimistic market estimates
- Calculate usable equity after the existing mortgage and target LVR
- Keep the investment deposit split separate from private borrowing
- Test combined repayments and cash buffers across both loans
Separate loan split
A distinct investment-purpose split can make the flow of borrowed funds easier to document than mixing investment and personal transactions.
Avoid unnecessary linking
Using both properties as security for one facility can be convenient, but may reduce control when selling or refinancing one property.
Serviceability
The equity release and purchase loan both add debt. Lenders assess total repayments, buffers, limits, expenses and acceptable rental income.
Compare the structure
Separate securities or cross-collateralisation?
The lender may offer either structure. Understanding control, valuation and exit implications before settlement can prevent avoidable complexity later.
Decision point
Separate loan securities
Properties linked together
Control
Each property generally supports its own loan or defined split.
The lender relies on multiple properties for the combined exposure.
Sale
Selling one property may require a simpler release assessment.
The lender may reassess the whole position and direct how sale proceeds are applied.
Refinance
One property or facility may be easier to move independently.
Moving one loan can require valuations and restructuring across several securities.
Valuation
Equity and LVR are clearer for each security.
Surplus equity in one property can support a shortfall in another.

Common questions
Clear answers for Victorian property investors
What is usable equity?
Usable equity is the amount a lender may allow you to borrow against a property after considering its valuation, existing secured debt, acceptable LVR and your borrowing capacity.
Can equity cover the full investment deposit and costs?
Potentially, if there is sufficient usable equity and serviceability. Borrowing the deposit means the effective debt across both facilities can be high, so repayments and buffers need careful modelling.
Does using equity change the ownership of my home?
No, but it increases debt secured against the property. If repayments cannot be maintained, secured properties may be at risk. Obtain appropriate advice before proceeding.
Should the equity release be a separate loan?
A separate investment-purpose split is often useful for clarity and record-keeping. Your accountant or tax adviser should advise on deductibility and records for your circumstances.
Can I access equity without refinancing my current lender?
Sometimes the existing lender can create a new split or top-up. Refinancing may provide alternatives, but costs, policy, pricing and the effect on both properties should be compared.
