Using your equity as a deposit when you already own a home

Equity 101: how it links to your deposit
If you already own a property, your deposit for the next place often does not come from cash in the bank. It usually comes from equity.
Equity is:
The difference between what your property is worth and what you owe on it.
For example:
Home value: $900,000
Mortgage: $500,000
Equity: $400,000
Put simply, equity is the full gap between your home’s value and the debt, while usable equity is the portion a bank is actually prepared to lend against once it applies its LVR limits. You might have $400,000 of equity on paper, but only part of that can be turned into a deposit.
Banks will only let you borrow up to a certain percentage of the value, depending on whether the property is owner occupied or an investment.
For owner occupied homes, the standard cap is 80% LVR
For residential investment properties, it is 70% LVR, which equates to a 30% deposit
The difference between that cap and your current loan is your usable equity.
Using the example above:
Maximum lending at 80%: $900,000 × 80% = $720,000
Current loan: $500,000
Usable equity: $220,000
That $220,000 can, in many cases, be used as part or all of the deposit for your next purchase.
Typical deposit expectations when you are moving home
For someone buying a home to live in, deposit expectations do not change just because you already own.
Banks still anchor off a 20% deposit for a standard owner occupied purchase
They are allowed to do some lending above 80% LVR, and from December 2025 this can be up to 25% of new owner occupier lending
The difference is that your deposit may now be a mix of:
Equity release from your current property
Net sale proceeds, if you sell
Any additional cash savings or investments
If you keep your current home and turn it into a rental, most banks will now treat that property as a residential investment. This means:
Your new home is assessed under owner occupied rules (usually up to 80% lending)
Your old home is assessed under investment rules (usually up to 70% lending), which can reduce how much equity you can draw out of it and may change the interest rates and product options on that loan
DTI rules also apply, so your income must support the combined lending across both properties during any overlap.
Common real world scenarios
Sell first, then buy
This is often the simplest on paper.
You sell your current home
Use the net proceeds as your deposit for the next place
Your loan structure then reflects only the new property
Pros:
Very clean from a bank perspective
No period of “double debt”
Easier to stay within DTI and LVR limits
Cons:
You may need temporary accommodation between properties
There is a risk of being priced out if the market moves while you are between homes
You may need to break any current fixed terms in order to pay off the existing debt
Buy before you sell (bridging)
Here you buy your next home first, while still owning the existing one. For a period, the bank is exposed to two properties and two loans.
There are two broad flavours:
Open bridge: where sale is intended but not yet confirmed
Closed bridge: where you have an unconditional sale on your existing home, with a known settlement date
The bank will usually:
Secure lending over both properties
Test your ability to service the peak debt position within DTI and internal stress test rates
Expect the bridge to be short term and to clear on sale
This can work well if you have strong income and know your existing property will be saleable, but it does increase risk and complexity.
Keeping the existing home and buying again
This is where things become more “investor flavoured”.
Example:
You keep your current home as a rental
You buy a new home to live in
The deposit for the new home comes from the equity in your current one
From the Reserve Bank’s perspective:
The property you live in is owner-occupied
The retained property is generally treated as a residential investment if it generates rent
Investor lending is subject to stricter LVR settings:
Investor loans are usually limited to a 70% LVR threshold
It is uncommon for banks to allow borrowers to release equity past 70% in today’s market, but non-banks may have appetite for this
In practice, that means:
Your old home will often be limited to 70% lending, capping how much equity you can extract
Your new owner occupied home will usually be assessed at 80% LVR, subject to the bank’s tolerance for high LVR owner occupied lending
The combined picture has to fit within both LVR and DTI constraints.
How banks actually calculate usable equity
Most lenders follow a similar process.
For each property:
Determine value
This might be a desktop estimate, e-valuation, or full registered valuation depending on the scenario
Apply maximum LVR
80% if owner occupied
70% if residential investment, although there can be some exceptions and new build flexibility
Subtract current debt
The difference is your theoretical usable equity
Overlay DTI and affordability
Even if you have plenty of equity, income and DTI caps can limit how much the bank will actually lend
You can then combine usable equity from multiple properties as the deposit for a new purchase.
For example:
Own home: $900k value, $500k loan, 80% cap gives $220k usable
Rental: $800k value, $500k loan, 70% cap gives $60k usable
Total usable equity: $280k
If you use that as a 20% deposit, your price range is around $1.4m. If you use it as a 30% deposit on an investment, your range is lower.
Risks and trade-offs to think about
More leverage across the whole portfolio
Using equity increases your overall debt, as the deposit itself is not “cash”
Cross security
Some structures tie properties together under a single facility
This can increase the bank’s control if things go wrong, or you need to sell one of your properties
We highly suggest a “Split banking” strategy for this reason
Market movements
A downturn can compress equity across several properties at once
Higher leverage makes you more sensitive to valuation changes
Cash flow pressure
Even if equity looks strong, running costs, vacancies, and rate rises can bite
Exit flexibility
The way loans are structured can affect how easily you can sell one property without major reshuffling
Return on investment
While your current home may suit your needs, this doesn’t necessarily mean it is going to perform well as an investment property
These are not reasons to avoid using equity, but they are reasons to plan carefully instead of just maximising the next purchase price.
Practical next steps for movers and upgraders
Get a current valuation view on your existing properties
Run a usable equity calculation based on 80% and 70% caps
Map out different scenarios
Sell then buy
Buy then sell
Keep and convert to investment
Check how each scenario looks under DTI and servicing tests
Decide how much risk you are genuinely comfortable carrying, not just what is technically possible
From there, you can design a deposit and lending structure that supports your lifestyle plans rather than boxing you in.
