Why Your Loan Structure Matters More Than Your Rate

Most investors focus on rates. Smart investors focus on structure. Here's why:

💸

Tax Deductibility

Wrong structure: You can't claim some interest as a tax deduction.

Right structure: Every dollar of interest is fully deductible at your marginal tax rate.

Potential impact: $5K-$15K/year in tax savings

🏦

Cash Flow Control

Wrong structure: High monthly repayments eat your rental income and require constant top-ups.

Right structure: Interest-only with offset = lower repayments, better cash flow, pay down when you want.

Monthly savings: $800-$2,500

📈

Future Flexibility

Wrong structure: Locked into one product. Can't adapt to market changes or life events.

Right structure: Split loans let you hedge rates, access equity, and adjust as needed.

Value: Priceless when rates change

🔐

Asset Protection

Wrong structure: Personal and investment debts mixed = ATO complications and legal risks.

Right structure: Separate facilities keep investment clean, compliant, and auditable.

Peace of mind: 100%

4 Investment Loan Structures (Which Is Right for You?)

Each structure has pros and cons. We'll match you to the best one for your situation:

1️⃣ Interest-Only Loan

Most Popular for Investors

Pay only interest for 1-10 years. Principal stays the same. Lower repayments = better cash flow.

✅ Best For:

  • Maximizing cash flow
  • Negatively geared properties
  • Short-term holds (5-10 years)
  • High-income earners who want tax benefits

📊 Example: $600K Loan

Principal & Interest:
$3,400/month
Interest-Only:
$2,200/month
Save $1,200/month!
Pros:
  • Lower monthly repayments
  • Maximize tax deductions
  • Better cash flow
  • More money for other investments
Cons:
  • Debt doesn't reduce
  • Slightly higher rates (0.1-0.3%)
  • Must convert to P&I eventually

2️⃣ P&I Loan + 100% Offset Account

Maximum Flexibility

Pay down principal, but park your cash in offset to reduce interest. Best of both worlds.

✅ Best For:

  • Building equity while staying flexible
  • Investors with irregular income
  • Those wanting to pay down debt faster
  • People with high cash savings

📊 How Offset Saves You Money:

Loan: $600K @ 6.5% = $39,000/year interest

Offset Balance: $100K in offset account

Interest Charged: Only on $500K = $32,500/year

💰 Annual Saving: $6,500 (while keeping $100K accessible!)

Pros:
  • Build equity automatically
  • Reduce interest with offset
  • Access your cash anytime
  • Pay loan off faster
Cons:
  • Higher monthly repayments
  • Less tax deductions over time
  • Requires discipline to keep offset funded

3️⃣ Split Loan Structure

Best Risk Management

Split your loan into multiple parts (e.g., 50% fixed, 50% variable). Hedge your bets on interest rates.

✅ Best For:

  • Risk-averse investors
  • Uncertain rate environments
  • Long-term holds
  • Investors wanting certainty + flexibility

📊 Example Split: $600K Loan

Split 1: $300K Fixed (5yr)
✓ Rate locked at 6.2%
✓ Certainty on repayments
✓ Protected if rates rise
Split 2: $300K Variable + Offset
✓ Current rate 6.5%
✓ Redraw/offset available
✓ Extra repayments allowed

Result: Protection from rate rises + flexibility to pay down debt

Pros:
  • Hedge against rate movements
  • Flexibility + certainty
  • Can mix interest-only + P&I
  • Customize to your risk appetite
Cons:
  • More complex to manage
  • May pay 2 sets of fees
  • Need to track multiple accounts

4️⃣ Line of Credit (LOC)

For Experienced Investors

Revolving credit facility. Draw down equity as needed. Interest charged only on what you use.

✅ Best For:

  • Active property investors (2+ properties)
  • Quick access to equity for deposits
  • Renovation projects
  • Sophisticated investors who understand the risks

📊 How LOC Works:

Property Value: $800K

Existing Debt: $400K

Available Equity (80% LVR): $640K - $400K = $240K LOC limit

You Draw: $80K for next deposit

Interest Charged: Only on $80K (not full $240K limit)

Pros:
  • Instant access to equity
  • Pay interest only on what you use
  • Perfect for deposits on next property
  • Flexible draw-down and repayment
Cons:
  • Higher interest rates (0.5-1% premium)
  • Temptation to overspend
  • Annual review required
  • Can be called in by lender

🧾 Tax Deductibility: The #1 Rule You Can't Break

Get this wrong and the ATO will disallow your interest deductions (costing you thousands)

✅ CORRECT: Keep Investment Loans Separate

  • Scenario: You buy investment property for $700K with $140K deposit + $560K loan
  • Loan Purpose: 100% for investment property purchase
  • Tax Outcome: 100% of interest is tax-deductible at your marginal rate
  • Annual Deduction: $36,400 @ 6.5% = save $16,380/year (45% tax bracket)

❌ INCORRECT: Mixing Personal & Investment Debt

  • Scenario: You refinance and use $50K from investment loan for personal car
  • Loan Purpose: Mixed (investment + personal use)
  • Tax Outcome: ATO may disallow $3,250/year of interest deductions
  • Lost Tax Benefit: $1,462/year (45% bracket) = $14,625 over 10 years!

🔑 The Golden Rule: Purpose Test

The ATO doesn't care what security you use (your home, investment property, etc.).

They only care about PURPOSE: What did you use the borrowed money for?

  • ✅ Borrowed to buy/improve investment property = Deductible
  • ✅ Borrowed to buy shares/income-producing assets = Deductible
  • ❌ Borrowed to buy personal car/holiday/renovate PPOR = NOT deductible
  • ❌ Borrowed for investment, then redraw for personal use = That portion NOT deductible

5 Costly Loan Structure Mistakes (And How to Avoid Them)

1

Using Redraw for Personal Expenses

The Problem: You make extra repayments on your investment loan, then redraw $20K to buy a car.

Tax Impact: That $20K is no longer tax-deductible debt. You lose ~$1,300/year in deductions.

The Fix: Use offset accounts instead of redraw. Offset doesn't change loan purpose.

2

Paying Down Investment Loan First

The Problem: You have $50K spare cash. You pay down your investment loan instead of your home loan.

Tax Impact: You reduce tax-deductible debt (bad!) instead of non-deductible debt (good!).

The Fix: Pay down non-deductible debt first (PPOR). Keep investment debt as long as possible.

3

Converting Investment to PPOR Without Restructure

The Problem: You move into your investment property without adjusting the loan structure.

Tax Impact: Interest is no longer deductible once it becomes your main residence.

The Fix: Split the loan or restructure BEFORE moving in to preserve deductibility.

4

Cross-Collateralizing Properties

The Problem: Lender uses both your PPOR and investment as security for one big loan.

Tax Impact: Hard to separate debt for tax purposes. Limits future refinance options.

The Fix: Keep each property on separate loan facilities. Clean separation = flexibility.

5

Not Documenting Loan Purpose

The Problem: You can't prove to ATO what you used the borrowed funds for.

Tax Impact: ATO can disallow ALL interest deductions if you can't prove purpose.

The Fix: Keep clear paper trail: contracts, settlement statements, bank transfers.

Investment Loan Structure FAQs

Should I choose interest-only or principal & interest for investment?

Interest-only is generally better for investors because:

  • Lower monthly repayments = better cash flow
  • Maximize tax deductions (interest stays high)
  • Free up cash for other investments

However, P&I makes sense if you want to pay down debt aggressively or the property is positively geared.

Can I claim interest on a loan secured by my investment property if I use funds for personal purposes?

No. Tax deductibility depends on purpose, not security.

If you borrow against your investment property but use the money to buy a car, that interest is NOT deductible.

Only interest on funds used to generate assessable income (rent, dividends, business income) is deductible.

What's the difference between offset and redraw for investors?

Offset: Separate account. Your cash stays separate from the loan. Safe for tax purposes.

Redraw: Extra repayments reduce the loan. Redrawing can contaminate loan purpose and affect deductibility.

For investors: Always use offset. It's safer and more flexible.

How long can I have interest-only on an investment loan?

Most lenders offer 1-10 years interest-only, with 5 years being the most common initial term.

After the interest-only period ends, the loan reverts to principal & interest for the remaining term.

You can often refinance or extend interest-only with another lender when your term expires.

Should I fix or go variable on an investment loan?

Variable is generally better for investors because:

  • You get offset accounts (most fixed loans don't offer this)
  • More flexibility to make extra repayments
  • No break fees if you refinance or sell

Consider a split loan (50% fixed, 50% variable) if you want rate certainty + flexibility.

What is debt recycling and how does it work?

Debt recycling is the strategy of converting non-deductible debt (PPOR) into tax-deductible debt (investment).

Example:

  • You have $300K PPOR loan + $200K investment loan
  • You make extra $50K payment on PPOR (reducing it to $250K)
  • You redraw $50K from PPOR and invest in shares
  • That $50K is now tax-deductible because it's for income-producing assets

Over time, you convert your entire PPOR loan into deductible investment debt.
