Simple hacks to calculate home equity for refinancing

Home equity is the portion of your property you own outright, after you subtract what you still owe on your mortgage.

Most lenders will let you borrow against up to 80% of your property's value without paying lenders mortgage insurance. If your property is worth more now than when you bought it, or you've paid down your loan, you could have access to usable equity for renovations, investment, or consolidating other debts. Knowing your equity position helps you understand whether refinancing to release equity makes sense.

How to calculate your current equity

Subtract your current loan balance from your property's current value. The difference is your equity.

If your Rosebud property is valued at the current median and you owe $400,000, your equity is the difference between those two figures. That number tells you what you own outright. To work out usable equity, multiply your property value by 0.8, then subtract your loan balance. That figure is what you could potentially access through refinancing your home loan without incurring lenders mortgage insurance.

Consider someone who bought in Rosebud a few years ago and has been making regular repayments. Their property value has increased in line with local demand, particularly for coastal homes within walking distance of the foreshore and Rosebud Village. They now owe $380,000 on a property valued at the suburb's current median. Using the 80% lending threshold, they could access a portion of that equity to fund a renovation or deposit on an investment property. The actual amount depends on their income, expenses, and the lender's serviceability assessment, but the equity calculation gives them a starting point.

Why property valuation matters more than you think

Your equity is only as accurate as the valuation you're working from.

Lenders don't rely on online estimates or what you think your property is worth. They order a formal property valuation report as part of the refinancing process. If the valuation comes in lower than expected, your usable equity shrinks, and so do your borrowing options. In Rosebud, where property types range from older weatherboard beach houses to newer architect-designed builds, valuation outcomes can vary significantly depending on location, condition, and recent comparable sales. A property on a larger block near the foreshore will be valued differently to a unit set back from the coast.

We regularly see clients surprised by valuation results, particularly when they've relied on online tools that don't account for local nuance. If you're planning to access equity for investment or renovations, it's worth understanding what drives valuation in your area before you apply.

What lenders look at beyond the equity number

Having equity doesn't automatically mean you can borrow against it.

Lenders assess your income, expenses, existing debts, and credit history before approving any refinancing application. Even if you have $150,000 in usable equity, a lender won't approve the drawdown if your income can't service the higher loan amount. This is where the conversation moves from property value to cash flow. If you're self-employed, lenders may require additional documentation. If you're carrying personal loans or credit card debt, refinancing to consolidate debt into your mortgage could improve your serviceability by reducing your monthly commitments.

The equity calculation tells you what's possible in theory. Serviceability tells you what's possible in practice.

When refinancing to access equity makes sense

You should have a clear purpose for the funds and a plan to service the higher loan amount.

Refinancing to access equity works when the cost of borrowing is lower than the return you'll get from using the funds, or when it consolidates higher-interest debt into your mortgage. Borrowing against your home to fund a holiday or depreciating asset rarely makes financial sense. Borrowing to renovate a property in a tightly held coastal suburb like Rosebud, or to fund a deposit on an investment property, could. The key is understanding the long-term impact on your repayments and whether your income can absorb the change.

In our experience, the clients who get the most value from equity release are the ones who've modelled the numbers carefully and understand exactly what they're signing up for. If your fixed rate period is ending and you're reviewing your loan anyway, it's worth checking your equity position at the same time.

How to check your equity without applying for a loan

You can estimate your equity using your most recent loan statement and a realistic property valuation.

Your loan statement shows your current balance. For valuation, you can use recent comparable sales in your street or suburb, but keep in mind that lenders will apply their own assessment. If you want a more accurate figure before committing to a refinancing application, some lenders offer desktop valuations or kerbside assessments for a smaller fee. These won't replace a full valuation, but they give you a clearer picture than an online estimate.

If you're serious about refinancing, we can help you request a valuation as part of the process. It's one less thing to guess at, and it gives you a concrete number to work from when comparing loan options.
