Using equity to Invest

Home equity is the difference between your property's current market value and what you still owe on your mortgage. As you pay down your loan and your property increases in value, your equity grows. For example, if your home is worth $1,000,000 and you owe $400,000, your equity is $600,000. Equity is the foundation for using equity to invest, renovate, or consolidate debt.

Usable equity is the portion of your equity that lenders will allow you to borrow against. Most lenders cap borrowing at 80% of your property value (to avoid LMI). The formula is: usable equity = (property value x 80%) minus your current loan balance. For a $1,000,000 home with a $400,000 loan, usable equity is ($800,000 minus $400,000) = $400,000. Use our home equity calculator for your exact figure.

There are four main ways to access equity: a cash out refinance (replace your loan with a larger one and withdraw the difference), a top up loan (increase your existing loan limit), a separate split loan (add a new loan secured against your property), or a line of credit (revolving access up to an approved limit). Our mortgage broker team recommends the best option based on your purpose, tax situation, and LVR.

A cash out refinance replaces your existing mortgage with a new, larger loan. The difference between the old and new loan amounts is released as cash for you to use. This is the most common equity release method for large, one-time purposes like funding an investment property deposit. A cash out refinance also gives you the opportunity to switch to a lower interest rate and better features at the same time.

A top up loan increases the limit on your existing mortgage without changing lenders. It is the simplest way to access equity and often the fastest. However, a top up loan can create a mixed-purpose loan (personal and investment) which complicates tax deductions. Our mortgage broker team advises on whether a top up loan or separate split is better for your situation.

A separate split loan creates a new, distinct loan secured against your property, keeping it completely separate from your personal home loan. This is the preferred structure when using equity to invest because it keeps your tax-deductible investment debt clearly separated from your non-deductible home loan. Clean separation simplifies tax reporting and ensures you claim maximum tax deductions. Our mortgage broker team always recommends a separate split for investment purposes.

A line of credit provides revolving access to your equity up to an approved limit, similar to a credit card. You only pay interest on the amount you have drawn, not the full limit. This suits ongoing or unpredictable needs. However, a line of credit requires strong financial discipline because there are no fixed principal repayments. Our mortgage broker team advises whether a line of credit suits your financial profile.

The rule of four is a quick guide for estimating how much investment property you can afford based on your usable equity. Multiply your usable equity by four to get an approximate maximum purchase price. This works because it allows for a 20% deposit plus approximately 5% for purchase costs. For example, $150,000 in usable equity could fund a $600,000 investment property. Our mortgage broker team provides precise calculations based on your actual situation.

Your LVR (loan to value ratio) determines how much equity you can access and the rate you pay. Most lenders allow equity release up to 80% LVR without LMI. Below 60% LVR, you typically access the best rates. Each equity withdrawal increases your LVR, so our mortgage broker team ensures your LVR stays within the best rate bands. Read our LVR guide for a detailed explanation.

Cross-collateralisation occurs when a lender links multiple properties together as security for your loans. This means you cannot sell one property without the bank reassessing your entire position, and problems with one property can affect the other. When using equity to invest, our mortgage broker team structures your loans to avoid cross-collateralisation, keeping each property and loan independent for maximum flexibility.

Interest is tax-deductible when the borrowed funds are used for income-producing purposes (such as buying an investment property). Interest on equity released for personal purposes (renovations on your own home, holidays, debt consolidation) is generally not tax-deductible. This is why a separate split loan is essential when using equity to invest. Our mortgage broker team structures your loans for maximum tax deductions. Consult your accountant for personalised advice.

Debt recycling is a strategy that converts non-deductible home loan debt into tax-deductible investment debt. You draw equity from your home, invest in income-producing assets, then use the investment income to pay down your non-deductible home loan faster. Over time, a greater proportion of your total debt becomes tax-deductible. This strategy requires careful structuring with separate loan splits. Our mortgage broker team sets up the loan architecture and you should work with your accountant on the investment component.

Yes. Using equity to invest means you do not need a separate cash deposit. Your usable equity acts as the deposit on the investment property. Many Australians buy their first investment property entirely through an equity release from their home. The equity funds the deposit and purchase costs, and you take out a new investment property loan for the remainder. Our home equity calculator shows your available amount.

You generally need at least 20% of the investment property's value plus approximately 5% for purchase costs (stamp duty, legal fees). Using the rule of four, $100,000 in usable equity could fund a $400,000 property, while $200,000 could fund an $800,000 property. Our mortgage broker team calculates your exact position and identifies the best investment price range for your equity level.

Yes. The property valuation determines your property's worth, which directly affects your LVR and usable equity. A higher valuation means more equity available. Different lenders value properties differently. Our mortgage broker team knows which lenders provide the highest valuations in your area, maximising the equity you can access. Read our bank valuations guide for more detail.

Yes. If you refinance or take a top up loan, you can maintain or add an offset account. Keeping savings in your offset account reduces the interest on your non-deductible home loan portion while your investment split earns tax-deductible interest. This is an important strategy for maximising the benefit of using equity to invest. Our mortgage broker team ensures your offset account is linked to the right loan split.

Releasing equity increases your total debt, which means higher repayments and greater exposure to interest rate changes. If property values fall, your LVR increases and you may have less flexibility. If you cannot meet the higher repayments, your home is at risk. Our mortgage broker team ensures you leave a reasonable equity buffer (do not borrow the maximum) and stress-tests your repayments against potential rate increases. Never use all your usable equity.

Equity release for renovations typically offers rates of 5% to 7%, compared to personal loan rates of 10% to 15%. On a $100,000 renovation, the difference in interest can be $5,000 to $8,000 per year. However, using equity extends the loan term (30 years versus 5 to 7 years for a personal loan). Our mortgage broker team models both options and recommends maintaining higher repayments to pay off the renovation portion faster.

Yes. Self-employed borrowers can access equity through the same methods (cash out refinance, top up loan, separate split, line of credit). Documentation requirements are stricter, typically requiring 2 years of tax returns and financial statements. Our mortgage broker team knows which lenders are most flexible for self-employed equity releases.

A top up loan with your existing lender can be approved in days. A cash out refinance or separate split with a new lender typically takes 2 to 4 weeks from application to settlement. A line of credit setup is similar. Our mortgage broker team manages the entire process to minimise delays and ensure fast access to your equity when you need it.

Yes. You can access equity from any property you own, whether it is your home or an investment property. The same LVR rules apply. This is how property portfolio investors fund their second, third, and subsequent investment property purchases. As each property grows in value, the equity can be recycled into the next purchase.

Negative gearing occurs when the costs of your investment (including loan interest) exceed the rental income, creating a tax-deductible loss. When using equity to invest in property, the interest on the investment loan contributes to the negative gearing calculation. A properly structured separate split loan maximises the deductible interest. Our investment property guide explains negative gearing in full detail.

Borrowing power for equity release depends on your income, existing debts, living expenses, and your LVR after the equity release. Lenders assess whether you can service the higher total debt. If using equity to invest, expected rental income (at 80% of market rent) also factors in. Each lender calculates differently. Our mortgage broker team compares 35+ lenders to maximise your borrowing power for equity release.

Yes. A mortgage broker compares equity release options across 35+ lenders, structures the loan for tax efficiency (separate splits, avoiding cross-collateralisation), identifies lenders with the highest property valuations to maximise usable equity, and handles the entire process. The service costs $0. Your bank can only offer its own products and may not recommend the best structure for using equity to invest.
