How Equity Actually Works (And Why It’s One of the Most Powerful Tools Homeowners Have)

If you’ve owned your home for a while, you’ve probably heard someone say, “Just use your equity.”

It’s one of the most common phrases in property conversations but it’s also one of the most misunderstood.

So, what is equity, and how does it actually work?

What is equity?

Equity is the difference between what your home is worth and what you still owe on your mortgage.

What you own vs what you owe

In simple terms, equity is the portion of your home that you own.

For example:

• Home value: $900,000

• Mortgage balance: $600,000

Your equity is $300,000.

Does having equity mean you can borrow all of it?

Not necessarily.

Many lenders prefer borrowers to retain at least 20% equity in their property, although this can vary depending on the lender and your individual circumstances.

Using the same example:

• Home value: $900,000

• 80% of the property’s value: $720,000

• Current mortgage: $600,000

This could mean there is around $120,000 of usable equity available, subject to lending criteria and affordability.

What can you use equity for?

Equity can help you achieve a range of financial goals, including:

• Purchasing your next home before selling your current one.

• Buying an investment property.

• Buying a business

• Funding renovations that add value to your home.

• Consolidating higher-interest debt into your mortgage (where appropriate).

• Purchasing a business or investing in an existing business (subject to lender criteria and suitability).

• Helping family members into the property market.

Every situation is different, so the best option depends on your goals and financial position.

Equity is only part of the picture

One of the biggest misconceptions is that if you have equity, you can automatically access it.

In reality, lenders also assess whether you can comfortably afford the additional borrowing. They’ll consider factors such as your income, existing commitments, expenses and overall financial position.

That’s why two homeowners with the same amount of equity may have very different borrowing outcomes.

Why understanding your equity matters

Whether you’re thinking about upsizing, investing, renovating or simply planning for the future, understanding your equity gives you more options.

It can help you make informed decisions about what’s possible today and what you could work towards in the future.

Frequently Asked Questions

• Is equity the same as cash?

  No. Equity represents the value you own in your property. To access it, you generally need to apply for additional lending and meet the lender's affordability requirements.

• Can I use equity as a deposit instead of cash?

  Yes, many homeowners use available equity in their existing property instead of a cash deposit when purchasing another home or investment property, subject to lending criteria.

• Can I use equity before I sell my house?

  In some cases, yes. Depending on your financial position and lender approval, you may be able to use the equity in your current home to purchase another property before selling.

• Can falling house prices reduce my equity?

  Yes. If your property's market value decreases, your equity may also reduce, even if you've continued making mortgage repayments.

• Does paying off my mortgage increase my equity?

  Yes. Every mortgage repayment that reduces your loan balance increases your equity. Equity can also grow if your property's value increases over time.

• Can refinancing help me access equity?

  Refinancing may allow you to restructure your lending and, where appropriate, access available equity. Whether this is possible depends on your financial position and the lender's assessment.

• Can I use equity to help my children buy their first home?

  Some homeowners choose to use equity to help family members into the property market, either by providing a gift, loan, or acting as a guarantor. The right option depends on your circumstances and should be carefully considered.
