What Is Home Equity and Why Does It Matter for Refinancing?
Home equity is the portion of your property you own outright, calculated by subtracting your current loan balance from your property's current market value. Lenders typically allow you to access up to 80% of your property value when refinancing, which means your usable equity sits between what you currently owe and that 80% threshold.
In Shailer Park, where property values have shifted over the past few years, many homeowners find themselves with more equity than they realise. A property purchased several years ago may have increased in value while the loan balance has steadily decreased through regular repayments. That combination creates equity you can use to fund an investment property purchase, major renovation, or debt consolidation.
The calculation itself is straightforward: if your property is now valued at $600,000 and you owe $350,000, your equity is $250,000. However, the amount you can actually access depends on how much the lender will allow you to borrow against the property value. At 80% of $600,000, the maximum loan would be $480,000. Subtract your existing $350,000 loan, and you have $130,000 in accessible equity before factoring in refinancing costs.
How Lenders Value Your Property During Refinancing
Lenders use their own valuation process rather than relying on online estimates or recent sales in your street. They may conduct a desktop valuation using recent comparable sales data, or they may send a registered valuer to inspect the property. The valuation method depends on the loan amount, property type, and lender policy.
Shailer Park's mix of established family homes and newer townhouse developments means valuation outcomes can vary depending on your property type and location within the suburb. A renovated Queenslander-style home near Shailer Park State School will be assessed differently to a two-bedroom unit near the shopping precinct on Bryants Road. The valuer considers recent sales of similar properties, the condition of your home, and any improvements made since purchase.
If the valuation comes in lower than expected, your accessible equity shrinks. Consider a scenario where you believe your property is worth $650,000 based on recent sales, but the lender's valuer assesses it at $620,000. That $30,000 difference reduces your accessible equity by the same amount, which could affect whether you have enough funds for your intended purpose.

Calculating Usable Equity With an 80% Loan-to-Value Ratio
Most lenders cap refinancing at 80% loan-to-value ratio (LVR) to avoid lenders mortgage insurance. This means your total loan after refinancing cannot exceed 80% of the property's current value. The calculation determines how much additional borrowing capacity you have available.
Start with your property's current valuation and multiply by 0.8 to find the maximum loan amount. Subtract your existing loan balance to find your usable equity. If your Shailer Park property is valued at $580,000, the maximum loan at 80% LVR is $464,000. With an existing loan of $320,000, you have $144,000 in usable equity. From that figure, subtract refinancing costs such as discharge fees from your current lender, application fees, and valuation fees, typically between $2,000 and $4,000 depending on the lender.
Some lenders allow you to borrow up to 90% or even 95% LVR, but this requires paying lenders mortgage insurance, which adds thousands to your upfront costs. For most refinancing purposes, staying at or below 80% LVR makes more financial sense unless you have a specific reason to access additional funds and are willing to cover the insurance cost.
When Equity Calculations Change Your Refinancing Strategy
The amount of equity you can access directly influences what you can achieve through refinancing your mortgage. If your goal is to access funds for an investment property deposit, you need enough equity to cover that deposit plus the associated purchase costs while staying within the 80% LVR limit.
In a scenario where you want to access equity to purchase an investment property, your existing loan balance and current property value determine whether you can proceed. If your Shailer Park home is valued at $620,000 and you owe $380,000, your usable equity at 80% LVR is $116,000 before costs. After refinancing costs, you might have $113,000 available. Whether that amount is sufficient depends on the investment property price and the deposit required by the lender for that purchase. If you need a 20% deposit on a $500,000 investment property, you would need $100,000 plus another $15,000 to $20,000 for stamp duty and other purchase costs, which fits within your available equity.
If the numbers fall short, you have three options: wait until your loan balance decreases further through regular repayments, wait for property values to increase, or adjust your investment property budget. Running the equity calculation early in your planning process helps you make informed decisions rather than discovering shortfalls during the refinance application process.
How Property Improvements Affect Your Equity Position
Renovations and improvements can increase your property value, which in turn increases your equity. However, not all improvements add equivalent value in the eyes of a lender's valuer. Structural improvements such as adding a bedroom, updating a kitchen, or building a deck tend to have more impact on valuation than cosmetic changes like painting or landscaping.
If you have recently completed renovations on your Shailer Park property, make sure the valuer is aware of the work. Provide receipts, permits, and before-and-after photos to support a higher valuation. A homeowner who has added a covered outdoor entertaining area and updated the bathroom may see their property value increase by $40,000 to $60,000, which translates to an additional $32,000 to $48,000 in accessible equity at 80% LVR.
Keep in mind that the valuer assesses what similar properties have sold for recently, not what you spent on improvements. If you invested $50,000 in renovations but comparable sales do not reflect that level of improvement, the valuation may not increase by the full amount spent.
Using a Loan Health Check to Review Your Equity Position
A loan health check is a structured review of your current loan, property value, and financial position. It involves calculating your current equity, comparing your current interest rate to what is available in the market, and identifying whether your loan structure still fits your needs.
Many Shailer Park homeowners have been on the same home loan for several years without reviewing whether it still suits their circumstances. Your equity position changes as your loan balance decreases and property values shift, which means opportunities to access equity or move to a lower rate can emerge without you realising it. A loan health check brings those opportunities to the surface and helps you decide whether refinancing makes sense based on your current goals.
If your equity calculation shows you have significant accessible funds and your current loan sits above market rates, refinancing may allow you to access funds while also reducing your ongoing repayments. If your equity position is limited but rates have dropped, you might refinance purely to reduce costs without accessing additional funds.
Frequently Asked Questions
How do I calculate how much equity I can access when refinancing?
Multiply your property's current value by 0.8 to find the maximum loan at 80% LVR, then subtract your existing loan balance. The result is your usable equity before refinancing costs.
What is the difference between total equity and usable equity?
Total equity is your property value minus your loan balance. Usable equity is the amount you can actually borrow, which is limited by the lender's maximum LVR, typically 80% to avoid mortgage insurance.
Do all lenders use the same property valuation when refinancing?
No, each lender conducts their own valuation using either a desktop assessment or a physical inspection. Valuation results can differ between lenders based on their criteria and the data they use.
Can I access equity if my property value has increased but I have not paid down much of the loan?
Yes, if your property value has increased, your equity grows even if your loan balance has only decreased slightly. The calculation depends on the current value, not the original purchase price.
What costs should I subtract from my usable equity calculation?
Subtract discharge fees from your current lender, application fees for the new loan, valuation fees, and settlement costs. These typically range from $2,000 to $4,000 depending on the lender and loan structure.
