Calculate Your Available EquityWhat is Home Equity?
Home equity is the portion of your property that you truly own - the difference between your home's current market value and what you owe on your mortgage.
Simple Equity Calculation
Based on recent comparable sales or registered valuation
What you still owe the bank
How Equity Grows
1. Paying Down Your Mortgage
Every mortgage payment includes principal repayment, reducing what you owe and increasing your equity.
Example: Paying $400/month in principal = $4,800 extra equity per year
2. Property Value Increases
As your property appreciates in value, your equity grows even without paying down the mortgage.
Example: 5% annual growth on $1M home = $50,000 extra equity per year
How Much Equity Can You Access?
Banks won't let you borrow 100% of your equity. They require you to maintain a buffer to protect both you and them from market fluctuations.
Maximum Borrowing Limits
Owner-Occupied Property
Living in the property yourself
Banks lend up to 80% of property value (you keep 20% equity minimum)
Investment Property
Rental properties you own
More conservative lending for investment properties (you keep 35% equity minimum)
Example: How Much Can You Access?
Scenario: $1M home with $600K mortgage (40% equity, 60% LVR)
This calculation assumes you meet income serviceability requirements and have good credit history.
Ways to Access Your Home Equity
1. Refinancing (Top-Up)
Increase your existing mortgage amount. The bank pays you the difference in cash, and you repay it as part of your regular mortgage. Learn about refinancing →
Best for: Large lump sum needs ($50K+), one-time projects
Pros: Lowest rate, simple structure, easy to understand
Cons: Refinancing costs ($1,500-$3,000), less flexibility
2. Revolving Credit / Line of Credit
Acts like a giant overdraft against your home. Borrow and repay as needed within your approved limit. Only pay interest on what you use.
Best for: Ongoing expenses, business use, property developers
Pros: Maximum flexibility, only pay interest on amounts used
Cons: Higher interest rate (floating only), requires discipline
3. Offset Mortgage
Your transaction account is linked to your mortgage. Savings offset mortgage interest, and you can redraw if needed (effectively accessing equity).
Best for: People with fluctuating income or expenses
Pros: Tax-effective savings, interest savings, emergency access
Cons: Higher interest rate than fixed, complex to understand
4. Second Mortgage / Home Equity Loan
Separate loan secured against your property equity, in addition to your primary mortgage. Usually from non-bank lenders.
Best for: Can't refinance main mortgage (high break fees), bad credit
Pros: Avoid breaking main mortgage, faster approval
Cons: Much higher interest rates (9-15%), higher fees

Risks of Using Home Equity
Increased Debt & Risk to Your Home
You're increasing your mortgage balance, meaning more interest and longer time to pay off. If you can't make repayments, you risk losing your home through mortgagee sale.
Property Value Fluctuations
If property values drop significantly, you could end up in negative equity (owing more than the house is worth), making it difficult to refinance or sell.
Interest Rate Rises
Higher mortgage balance means greater exposure to interest rate increases. A 2% rate rise on extra $100K borrowed = $2,000/year extra in payments.
Longer Debt Repayment Period
Spreading debt over 25-30 years means paying substantially more interest over time, even at low rates. Can delay debt freedom and retirement.
Temptation to Overspend
Easy access to large amounts of money can lead to unnecessary spending on wants rather than needs. Requires strong financial discipline.
Mitigating the Risks
- →Only borrow for value-adding or income-generating purposes
- →Maintain emergency fund of 3-6 months expenses
- →Stress test affordability at 2-3% higher interest rates
- →Keep total LVR below 70% to maintain buffer
- →Make extra repayments to pay down the additional debt quickly
Home Equity FAQs
How quickly can I access my home equity?
If staying with your current lender (topping up existing mortgage), typically 2-3 weeks from application to funds. If refinancing to a new lender, allow 4-6 weeks. Urgent situations can sometimes be expedited.
Can I access equity if I'm self-employed?
Yes, but you'll need 2+ years of financial statements showing consistent profitability. Banks are more conservative with self-employed applicants. A mortgage broker experienced with self-employed lending is highly recommended.
Do I need to explain what I'm using the equity for?
Yes, banks want to know the purpose. They're more likely to approve for value-adding renovations or investment than for holidays or lifestyle spending. Be honest - banks can decline applications if they think the purpose is too risky.
Is interest on home equity loans tax deductible?
Only if you use the borrowed equity for income-earning purposes (e.g., investment property deposit, business investment). If used for personal purposes like renovations on your own home, the interest is not tax deductible. Consult an accountant for specific advice.
What if my property value has decreased?
You can only access equity based on current value, not what you paid. If your property value has dropped, you may have less equity available than you think. Banks will require a registered valuation to confirm current value.
Can I access equity if I have a low credit score?
Difficult with mainstream banks. You may need to improve your credit first, or explore non-bank lenders who charge higher rates (9-15%). If you have significant equity (50%+), more options become available despite credit issues.
