How to use your home equity to get a cheaper home loan

A home successfully refinanced using the high equity built up.

As refinancers gear up to escape rising interest rates, there’s one tool in their arsenal they shouldn’t forget about: home equity. 

Home equity is the value of your homeownership, i.e. how much your share of your property is worth. As you pay down your mortgage, you build up equity because you own more of the property. Your equity can also rise as your property value does, whether due to renovations or capital growth

Usually, the more home equity you have, the better interest rates you could potentially access. Lenders like seeing borrowers with high equity because it means they're less likely to default on their payments and have a greater amount of security in their home.

As a rule of thumb: the safer borrower gets the lower interest rates. 

Your equity can lower your mortgage interest rate

If we look at statistics from the Mozo database, we can see this trend in action. According to our numbers, a refinancer with a loan-to-value ratio of 80% (i.e. 20% home equity) pays an interest rate 0.53% lower than someone with an LVR of 95% (i.e. 5% home equity). 

RELATED: Wait, what's the difference between LVR and equity?

So what does this 0.53% rate difference mean for your mortgage repayments? For a $400,000 home loan over 25 years, you could reduce your costs by $156 per month, or $1,872 yearly.

Here’s a breakdown of average variable rates based on LVR in the Mozo database. 

Home equity
LVRAverage variable rate
5% of property value95%7.38% p.a.
10% of property value90%7.13% p.a.
20% of property value80%6.85% p.a.
30% of property value70%6.81% p.a.
40% of property value60%6.77% p.a.

NOTE: Calculations current as of 12 January 2023. These averages assume an owner occupier making principal and loan repayments on a $400k loan.

Lenders may not always advertise LVR tiers lower than 80%, so this is where it's critical to do your own research, establish your LVR, and see if you can refinance to a lower rate – even with your own lender. 

How to calculate your home equity

To calculate your home equity, you need to know two basic things: the market value of your property, and any outstanding debt you have against it like mortgage debt or personal loan debt. 

Your home equity is then found using this equation:

Equity ($) = Home value - loan value

A property valuation can help you determine how much your home is worth.

To refinance, you’ll usually need at least 80% LVR (or 20% in home equity), although some lenders do accept LVRs of up to 90-95%.

Just bear in mind that refinancers with a LVR above 80% may have to pay Lenders Mortgage Insurance – even if you already paid LMI when you took out your first mortgage.

Banks also tend to be conservative in their property valuations, and property prices have swung wildly in the last few years. You may have more equity built up than you think!

Once you’ve got a handle on your home equity, it’s time to check out competitive deals for refinancers. Here are a few award-winning to get the ball rolling.
