Using home equity to buy an investment property: what to check first
See how home equity may support an investment-property deposit or costs, and why you still need to check serviceability, valuation, LVR and risk.
Key checks before you decide

Equity is an initial estimate, not available cash
Estimated property value less the current loan balance is estimated equity.
A property estimated at $900,000 with a $500,000 loan has estimated equity of $400,000.

Treat a property-appraisal figure as planning information until the lender's valuation and policy checks are complete.
Security and serviceability are separate questions
Equity is mainly a security question. Serviceability asks whether repayments can be met. An investment purchase generally needs both.
People with similar equity can have different outcomes because their income, commitments, property details and lender policy differ.
| Question | What a lender may review | Why it matters |
|---|---|---|
| Can security support lending? | Valuation, existing debt, total borrowing, LVR, property type and policy | A higher estimate does not settle the lender's view. |
| Can repayments be met? | Income, expenses, debts, rental-income treatment, rate assumptions and structure | Rent may not be counted in full and equity alone does not show repayment capacity. |
Broker note
How equity may fit into an investment purchase
A broker and lender will discuss the loan structureHome Loans / Loan decisionsCompare loan typesCompare fixed, variable, split, repayment type, offset, redraw, LVR and deposit trade-offs before choosing a structure.Open page . The information needed changes with the security and loan arrangement.
Prepare the existing property's loan statement, estimated value, ownership and fixed-rate constraints. Add the new purchase price, deposit, buying costsHome Loans / Loan decisionsDeposit and buying costsSeparate saved deposit, stamp duty, legal costs, lender fees, moving costs, and settlement cash.Open page , contract timing, debts, expenses, expected rent, vacancy and maintenance assumptions.
Ask which properties would secure which loans, what happens if values change and whether refinancing, valuation, discharge or settlement costs apply.
A lender may consider the existing property and the new property as security in different ways. Ask for a clear explanation of the proposed loan balances, the security each loan uses, and the consequences if the purchase does not settle.
Watch out
Plan for costs equity does not remove
Equity may help with a deposit or costs, but it does not remove the cost of owning or borrowing for an investment property.
Prepare a cash-flow view that includes the existing home loan and proposed investment loan, plus interest, rates, insurance, repairs, loan fees, valuation, conveyancing and possible LMIHome Loans / Loan decisionsLVR and LMI explainedUse this when a guide mentions loan-to-value ratio, lenders mortgage insurance, or low-deposit trade-offs.Open page where relevant.
Build a buffer for rent, interest-rate, repair and vacancy changes. If the plan works only under one optimistic valuation, rent or rate assumption, pause and seek advice.
Include the timing of each cost. A deposit, transfer duty, conveyancing, valuation and lender fees may fall due at different points, while repairs, insurance and vacancy costs can continue after settlement. Equity does not create cash flow for those commitments.
Watch out
Check later repayments as well as the first payment
Interest-onlyHome Loans / Loan decisionsPrincipal and interest vs interest-onlyUnderstand repayment-type trade-offs before choosing an interest-only or principal-and-interest structure.Open page repayments do not reduce principal during the interest-only period and repayments can rise afterward. They can cost more over the life of a loan than principal-and-interest borrowing.

A lower initial repayment does not resolve affordability, tax treatment or investment suitability.
Compare the existing home-loan repayment with the combined repayments after the purchase, using a rate and rent assumption you understand. A lender assessment may use different assumptions, so the comparison is for planning rather than a credit decision.

Borrowing to invest increases risk
Investment returns, property values and rent can fall while loan repayments remain due. A home used as security can be at risk if repayments cannot be met.
A mortgage broker can help with lending options and application preparation, but does not decide whether an investment suits your goals. Keep mortgage guidance separate from investment, tax and legal advice.

Test whether the household could meet the commitments if rent falls, rates rise, repairs are needed or the valuation is lower than expected.

Take the estimated equity, current loan balance and proposed purchase figures as discussion material, rather than assuming they establish a borrowing limit. The broker can identify which lender questions remain and when a valuation or formal assessment is relevant.
