How to Refinance Your Australian Home Loan for Property Investment in 2026

Refinancing your home loan can be a powerful strategy to unlock equity and fund your next property investment. With Australian property values remaining robust and interest rates evolving, 2026 presents unique opportunities for homeowners to leverage their existing assets. This guide walks you through the entire process, from assessing your equity to choosing the right lender and managing tax implications.


Understanding Equity and How It Fuels Investment

Equity is the difference between your property’s current market value and the outstanding balance on your mortgage. For example, if your home is worth $900,000 and you owe $400,000, your equity is $500,000. Lenders typically allow you to access up to 80% of this equity (minus any existing debt) without incurring Lenders Mortgage Insurance (LMI).

Calculating Usable Equity

To determine how much you can access:

1. Multiply your property value by 0.80 (e.g., $900,000 × 0.80 = $720,000).
2. Subtract your current loan balance ($720,000 – $400,000 = $320,000). This $320,000 is your usable equity, which can serve as a deposit for an investment property.

According to the Australian Bureau of Statistics (ABS), the median dwelling value in capital cities reached $942,000 in early 2025, reflecting a 6.8% annual increase. This growth has boosted equity for many homeowners, making refinancing an attractive option in 2026.

Step-by-Step Refinancing Process for Investment

Step 1: Assess Your Financial Position

Before approaching lenders, review your:

• Credit score: A score above 650 improves your chances of approval. Check your report via Equifax or Experian.
• Income stability: Lenders assess your ability to service both the existing and new loan. Provide recent payslips, tax returns, and proof of rental income if applicable.
• Existing debts: Reduce credit card limits and personal loans to improve your borrowing capacity.

Step 2: Research Lenders and Loan Products

Not all lenders treat investment refinancing equally. Compare:

• Interest rates: As of Q1 2026, variable investment rates range from 6.20% to 7.10%, while fixed rates for 3 years hover around 5.80%–6.50%.
• Features: Offset accounts, redraw facilities, and the ability to split loans can be crucial for tax planning.
• Fees: Look for discharge fees from your current lender, application fees ($300–$600), and valuation fees.

Lender Type	Typical Variable Rate (2026)	Max LVR for Investment	Key Feature
Major Bank	6.40% p.a.	90% (with LMI)	Package discounts
Online Lender	6.20% p.a.	80%	Low fees
Credit Union	6.55% p.a.	85%	Member benefits

Step 3: Submit a Refinance Application

Gather documents including:

• Identification (passport, driver’s licence)
• Proof of income (last 3 payslips, 2 years of tax returns if self-employed)
• Statements for all existing loans and credit cards
• Council rates notice for the property
• Rental income appraisal if the new property is already tenanted

Lenders will conduct a valuation of your existing property. Be aware that valuations may come in lower than market expectations, affecting your usable equity.

Step 4: Structure the New Loan

When refinancing for investment, you can:

• Increase your existing loan: Top up your current mortgage to release equity as cash.
• Take a separate investment loan: Keep the loans distinct for tax purposes. Interest on the investment portion is generally tax-deductible.
• Cross-collateralisation: Use both properties as security. This can increase borrowing power but ties the assets together, reducing flexibility.

Step 5: Settlement and Beyond

Once approved, your new lender pays out the old loan. Any excess funds are deposited into your account. Ensure you update any direct debits and redirect rental income if applicable.

Tax Implications of Refinancing for Investment

Understanding the tax rules is critical to maximizing your returns.

Deductibility of Interest

Interest on the portion of the loan used for investment purposes is tax-deductible. If you refinance and use the released equity to buy an income-producing asset, that interest can be claimed. However, if you mix purposes (e.g., using part for a new car), you must apportion interest carefully. The Australian Taxation Office (ATO) scrutinises loan purpose, so maintain clear records.

Capital Gains Tax (CGT)

Refinancing itself doesn’t trigger CGT, but selling the investment property later will. The CGT discount (50% for individuals holding the asset over 12 months) applies to the property’s gain. Keep records of all costs associated with the refinance, as they may form part of the cost base.

Depreciation and Negative Gearing

An investment property can be negatively geared if the rental income is less than the expenses (including interest). This loss can offset other income, reducing your taxable income. A quantity surveyor’s depreciation schedule can maximise deductions for new properties.

Strategies to Maximise Borrowing Power in 2026

Improve Your Serviceability

Lenders use a buffer (currently 3% above the loan rate) to assess serviceability. To boost your borrowing capacity:

• Reduce living expenses: Cut discretionary spending for at least 3 months before applying.
• Close unused credit facilities: Even a zero-balance credit card reduces your borrowing limit.
• Consider a fixed-rate loan: Lower rates improve serviceability, but weigh the risk of future rate changes.

Choose the Right Loan Structure

• Interest-only (IO) loans: Popular for investors, IO periods of up to 5 years keep repayments low, aiding cash flow. However, principal isn’t reduced, and rates are typically higher.
• Principal and interest (P&I): Builds equity faster and often attracts lower rates, but repayments are higher.

Leverage Government Schemes

The First Home Guarantee and Family Home Guarantee are for owner-occupiers, but some states offer stamp duty concessions for investors building new dwellings. Check state revenue office websites for 2026 updates.

Common Pitfalls to Avoid

• Overcapitalising: Don’t borrow more than you can comfortably service. Factor in vacancy periods and interest rate rises.
• Ignoring exit fees: Some fixed-rate loans have high break costs if you refinance early.
• Mixing loan purposes: Using an offset account with mixed funds can complicate tax deductibility. Consider a separate loan split for investment.
• Skipping professional advice: A mortgage broker and tax accountant can save you thousands.

FAQ

Can I refinance if my property value has dropped?

Yes, but your usable equity may be reduced. If your loan-to-value ratio (LVR) exceeds 80%, you might need to pay LMI or wait for values to recover. Some lenders offer LMI waivers for professionals, so explore your options.

How long does the refinancing process take?

Typically 4–8 weeks from application to settlement, depending on lender efficiency and valuation timelines. Digital lenders can sometimes complete it in 2–3 weeks.

Will refinancing affect my credit score?

A single application has a minor, short-term impact. Multiple applications within a short period can significantly lower your score, so avoid applying with several lenders simultaneously.

Is it better to refinance with my current lender or a new one?

Your current lender may offer a streamlined process, but you might miss out on better rates or features elsewhere. Always compare offers; a mortgage broker can help you negotiate.

Can I use equity from my home to buy an investment property outright?

Rarely, as most lenders cap cash-out at 80% LVR. You’ll likely need a separate investment loan for the remaining purchase price plus costs.
