How Much Equity Can You Safely Release from an Investment Property?

You can usually safely release 10–30% of an investment property’s value in Australia, provided your LVR stays around 70–80%, you can afford repayments at least 3% above today’s rates, and you hold 3–6 months of full holding costs in cash or offset. The exact amount depends on your income, portfolio size, tax position and how you’ll use the funds.

This guide walks through the numbers, safety rules and loan structures so you can decide, this week, how much equity you can safely release from your investment property.

Equity release decisions start with property value, loan balance and a safe target LVR.

1. Equity release basics for investment properties

1.1 What is equity and usable equity?

Equity is simply:

Current property value – current loan balance = equity

But you can’t (and shouldn’t) borrow all of it. Usable equity is the portion you can safely and sensibly draw out as an extra loan.

For geared investors, usable equity is decided by three filters:

1. LVR limits – what the lender will accept and what you’re comfortable with.
2. Serviceability – what you can repay under APRA’s 3% buffer.
3. Cash buffer rules – what keeps you safe if rates rise or rents fall.

A safe plan respects all three.

1.2 Why investors release equity

Common uses for equity from an investment property include:

• Deposit and costs for the next investment property.
• Renovations to lift rent or value.
• Building a standby equity facility as a war chest.
• Business or self‑employed cashflow, equipment or fit‑outs.
• Debt restructuring – consolidating expensive personal debt into a lower‑rate loan.

Each purpose has different risk and tax implications. If you’re comparing renovation versus buying another property, it’s worth also reading "Should You Use Home Equity to Renovate or Buy an Investment?" and "Using Home Equity Safely: Renovations, Investments and Buffers".

2. Core safety rules: how much is “too much” equity release?

2.1 The LVR guardrails

From a risk perspective, most geared investors are safest when each property sits somewhere between 60–80% LVR, with total portfolio LVR usually capped a little lower as you get larger.

A practical rule from our broader equity guidance is:

Target LVR after equity release: 70–80% (not the 90–95% many banks technically allow).

Why not push to 90%?

• LMI (Lenders Mortgage Insurance) usually applies above 80% LVR – a large, non‑deductible cost in many cases.
• Higher LVR magnifies the risk of negative equity if prices fall.
• Post‑2027, CGT and negative gearing changes will cut after‑tax returns for many investors, so excess leverage bites harder. (See "New CGT Rules For Geared Property Investors: Practical 2027 Playbook").

2.2 The buffer rule for multi‑property investors

From existing guidance on upgrades and equity use, a practical minimum buffer is:

• At least 3 months of all home + investment loan repayments in cash or offset; and
• Preferably 6 months of full holding costs (loan, rates, insurance, basic maintenance, landlord insurance, property management).

This aligns with the stress‑testing framework from our articles on safe gearing and portfolio stress testing.

2.3 The interest rate stress test

APRA currently expects lenders to test serviceability at at least 3% above the actual interest rate. As a personal rule of thumb, you should do the same.

Stress test: Could you comfortably cover your share of repayments if rates were 3% higher and the property had 3 months’ vacancy?

If the answer is “not really”, you’re already pushing too hard, before you even touch more equity.

3. Step‑by‑step: calculating how much equity you can safely release

3.1 Step 1 – Work out current value

You need a realistic current market value. Options:

• Desktop valuation (what many banks use for quick top‑ups).
• Full valuation ordered by the lender.
• Independent agent estimates – useful cross‑checks but not decisive.

For planning, be conservative. If the range is $820k–$880k, maybe plan at $830k–$850k.

3.2 Step 2 – Calculate equity and target LVR

Example:

• Investment property value (bank valuation): $800,000
• Current loan balance: $480,000 (60% LVR)

Your total equity is:

• $800,000 – $480,000 = $320,000 equity

Now apply a target LVR. Let’s compare 70%, 75% and 80%.

Maximum loan at 70% LVR = $800,000 × 70% = $560,000
Maximum loan at 75% LVR = $800,000 × 75% = $600,000
Maximum loan at 80% LVR = $800,000 × 80% = $640,000

Subtract your existing loan to see how much gross equity you could release:

This is lender‑side usable equity based purely on value and LVR.

3.3 Step 3 – Overlay your cash buffer rule

Next, work out how much cash/offset you must keep untouched.

Assume this property’s holding costs are:

• Loan repayments (interest‑only at 6.5% on $480,000): about $2,600/month
• Council + water rates, insurance, basic maintenance: approx $600/month

Total holding cost ≈ $3,200/month.

If you want a 6‑month buffer for this property alone:

• $3,200 × 6 = $19,200 needed as a buffer

In reality, your buffer needs to cover your whole portfolio and your home, not just this property. Many of our clients target 3–6 months of household and property costs in aggregate.

If you currently have $40,000 in offset against this loan and other loans, and you refuse to let your buffer fall below $25,000, then you can safely use at most:

• $40,000 – $25,000 = $15,000 of your existing cash; and
• Any new equity released that you don’t immediately park in buffers.

Often, part of the equity release is actually used to top up buffers (e.g. release $160k, allocate $140k for investment and $20k into offset as a bigger emergency fund).

3.4 Step 4 – Serviceability and repayment test

Now test how the higher debt affects your cashflow at stressed rates.

Continuing the example, suppose you lift the loan from $480k to $640k (80% LVR) on an interest‑only 5‑year split at 6.5%, with a stress test at 9.5% (6.5 + 3):

Scenario A – Before equity release

• Loan: $480,000
• Actual rate 6.5% IO → repayment ≈ $2,600/month
• Stressed at 9.5% → $3,800/month

Scenario B – After equity release to 80% LVR

• Loan: $640,000
• Actual rate 6.5% IO → repayment ≈ $3,470/month
• Stressed at 9.5% → $5,067/month

If your rent is $3,000/month and after expenses you currently chip in $400/month from your salary, post‑release you might be contributing $1,100–$2,000/month (depending on rate and vacancies).

That’s where negative gearing and the future 2027 tax changes matter. You can no longer assume the ATO will subsidise big losses forever, especially on established properties bought after 12 May 2026.

3.5 Step 5 – Convert to a safe equity number

Bringing it together, a practical rule is:

Safe equity release = lower of (LVR‑based capacity, buffer‑based limit, serviceability‑based limit)

In the $800k example, that might look like:

In this case, you might settle on a $100k–120k equity release, not the full $160k the bank would allow.

4. Safe LVR ranges for geared investors at different stages

There’s no single “correct” LVR for every investor. But there are sensible bands for different stages and risk appetites.

4.1 Typical safe LVR bands

These are guidelines, not hard rules. In practice, we tailor around:

• Job security and income volatility.
• Dependants and household spend.
• Portfolio spread (location, property types).
• Your genuine tolerance for seeing values and cashflow move around.

4.2 Investment vs home: where to hold the higher LVR?

In many cases it’s safer and more tax‑efficient to keep your home at a lower LVR and let the investment properties carry more of the leverage, because:

• Home loan interest is not deductible.
• Investment loan interest usually is deductible (subject to purpose and new rules).

However, this must be balanced against:

• The emotional and practical safety of a lower home LVR.
• Portfolio‑level risk if rental income stumbles.
