Understanding Home Loan Portability: How to Move Your Mortgage to a New Property in Australia

Moving house is a significant life event, and for many Australian homeowners, the thought of navigating a new home loan while selling an existing property can be daunting. However, there is a feature that can simplify this process: home loan portability. This guide explains what home loan portability is, how it works in Australia, its benefits and potential pitfalls, eligibility criteria, and a step-by-step process to help you decide if it’s the right move for you.

What Is Home Loan Portability?

Home loan portability, also known as loan substitution or security substitution, allows you to transfer your existing home loan from your current property to a new one without having to refinance or take out a completely new loan. In essence, you keep the same loan account, interest rate, features, and terms, but the property securing the loan changes.

This can be particularly useful if you’re selling your home and buying another simultaneously. Instead of discharging your old loan and applying for a new one—which can involve break costs, application fees, and a new credit assessment—you simply substitute the security property. The loan amount may remain the same, or you can increase or decrease it depending on your needs, though increasing the loan typically requires additional credit assessment.


How Does Home Loan Portability Work in Australia?

In Australia, home loan portability is offered by many lenders, but it’s not automatic. You must apply through your lender and meet their criteria. The process involves a legal mechanism where the mortgage over your old property is released, and a new mortgage is registered over the new property. The loan account itself stays active, and your repayment history, direct debits, and linked offset accounts may continue unchanged.

Key Steps in the Portability Process

1. Assessment and Approval: Your lender will assess the new property’s value and your financial situation. Even though you’re not refinancing, the lender needs to ensure the new security is acceptable.
2. Property Valuation: The lender will order a valuation of the new property to confirm it meets their lending criteria and to determine the loan-to-value ratio (LVR).
3. Legal Work: Solicitors or conveyancers handle the substitution of security. This includes discharging the mortgage on the old property and registering a new mortgage on the new one.
4. Settlement: The sale of your old home and purchase of the new one are coordinated. The lender releases the old security upon receiving the sale proceeds, and the new mortgage is registered.

It’s important to note that portability is usually only available if you’re buying and selling at the same time. If there’s a gap between selling and buying, you might need bridging finance or a separate loan.

Benefits of Home Loan Portability

1. Cost Savings

Porting your loan can save you money on discharge fees, application fees, and potentially break costs if you have a fixed-rate loan. It also avoids the need for a new loan establishment fee.

2. Retain Favourable Loan Terms

If you have a competitive interest rate, valuable features like an offset account, or a package discount, portability allows you to keep these benefits rather than starting fresh with a new loan.

3. Simpler Process

Because you’re not applying for a new loan, the paperwork and credit checks may be less extensive, though you’ll still need to provide some documentation.

4. Avoid Break Costs on Fixed Loans

If you have a fixed-rate loan, breaking it early can incur significant break costs. Portability may allow you to transfer the fixed rate to the new property, avoiding these fees. However, not all lenders permit this, so check your loan terms.

5. Continuity

Your loan account, repayment schedule, and linked accounts remain the same, reducing disruption to your finances.

Potential Drawbacks and Considerations

1. Not Always Available

Some lenders don’t offer portability, or they may restrict it to certain loan products. It’s essential to check your loan contract or speak to your lender.

2. Valuation and LVR Issues

If the new property is valued lower than expected, you might need to contribute additional funds to keep the LVR within acceptable limits. Conversely, if you want to borrow more, you’ll need to pass a credit assessment.

3. Timing Challenges

Portability works best when the sale and purchase settle on the same day. If the dates don’t align, you may need bridging finance, which adds complexity and cost.

4. Fees Still Apply

While you avoid some fees, there are usually costs for the legal work, valuation, and possibly a portability fee charged by the lender (often a few hundred dollars).

5. Fixed-Rate Limitations

Even with portability, fixed-rate loans may have restrictions. Some lenders won’t allow porting a fixed rate, or they may require you to break and re-fix at current rates.

Eligibility Criteria for Home Loan Portability

Lenders assess portability applications similarly to new loans, though the process is often streamlined. Typical eligibility requirements include:

• Good Repayment History: You must be up to date with your repayments and have a good credit record with the lender.
• Acceptable New Security: The new property must meet the lender’s criteria (e.g., location, type, condition) and have a satisfactory valuation.
• Loan-to-Value Ratio (LVR): The LVR on the new property should be within the lender’s limits. If you’re borrowing more than 80%, Lenders Mortgage Insurance (LMI) may apply.
• Serviceability: If you’re increasing the loan amount, you’ll need to demonstrate that you can afford the higher repayments. Even if the loan amount stays the same, some lenders may reassess serviceability.
• Same Borrowers: Usually, the borrowers on the loan must remain the same. Adding or removing a borrower typically requires a new loan application.

Step-by-Step Guide to Porting Your Home Loan

Step 1: Review Your Current Loan

Check your loan contract or contact your lender to see if portability is available and what conditions apply. Note any fees, fixed-rate break costs, and whether you can keep your current interest rate.

Step 2: Assess Your Financial Situation

Determine if you need to borrow more, less, or the same amount. Consider your equity in the current property and how much you’ll need for the new purchase, including stamp duty and other costs.

Step 3: Get a Property Valuation

Your lender will arrange a valuation, but you can also get an independent estimate to gauge the LVR. If the valuation is lower than the purchase price, you may need to cover the shortfall.

Step 4: Submit Your Application

Complete the lender’s portability application form. You’ll likely need to provide:

• Contract of sale for your current property
• Contract of sale for the new property
• Proof of income (if increasing the loan)
• Identification documents

Step 5: Legal and Settlement Process

Engage a solicitor or conveyancer to handle the legal aspects. They will coordinate with the lender to discharge the old mortgage and register the new one. Ensure settlement dates align to avoid bridging finance.

Step 6: Finalise the Port

Once settled, your loan will be secured by the new property. Confirm that your repayments, offset accounts, and other features are functioning correctly.

When Portability Might Not Be the Best Option

• You Want a Different Loan Structure: If you’re unhappy with your current loan’s features or rate, refinancing might be better.
• Significant Loan Increase: If you need to borrow substantially more, a new loan application might offer better rates or features.
• Changing Borrowers: Adding or removing a borrower usually requires a new loan.
• Lender Doesn’t Offer Portability: You’ll need to refinance with a new lender.

Home Loan Portability vs. Refinancing

Real-Life Example: Porting a Loan in Australia

Consider Sarah, who owns a home in Melbourne with a $400,000 mortgage at a competitive variable rate with an offset account. She sells her home for $650,000 and buys a new one for $750,000. She wants to keep her loan features and avoid break costs on her fixed-rate component. Sarah applies for portability with her lender. The lender values the new property at $750,000, and Sarah uses $250,000 from the sale proceeds as a deposit, keeping her loan at $400,000. The LVR is 53%, well within limits. The lender approves the substitution, and both settlements occur on the same day. Sarah pays a $300 portability fee and legal costs but saves thousands in discharge and application fees, and retains her low rate.

Recent Trends in Home Loan Portability (2023–2026)

In recent years, Australian lenders have increasingly offered portability as a feature to retain customers in a competitive market. According to the Australian Bureau of Statistics, housing loan commitments have fluctuated with interest rate changes, prompting borrowers to seek flexibility. Industry data from 2023 shows that about 30% of major bank home loans include portability options, with non-bank lenders also joining the trend.

The Reserve Bank of Australia’s cash rate adjustments between 2023 and 2025 have made fixed-rate portability particularly valuable for those who locked in low rates during the pandemic. However, the Australian Securities and Investments Commission reminds borrowers to carefully review terms, as some lenders may not honour the same fixed rate after porting.

FAQ

Can I port my home loan if I’m not selling my current property immediately?

Generally, portability requires simultaneous sale and purchase. If there’s a gap, you may need bridging finance or a separate loan. Some lenders offer a “substitution of security” without a sale, but this is less common and may have stricter conditions.

Will porting my loan affect my credit score?

Porting itself usually doesn’t require a full credit enquiry unless you’re increasing the loan amount. However, the lender may perform a soft check. It’s best to confirm with your lender.

What happens to my offset account when I port my loan?

In most cases, your offset account remains linked to the loan and continues to function as before. However, confirm with your lender, as some may require you to close and reopen the offset if the account is tied to the old property’s title.

Are there any government schemes that assist with loan portability?

There are no specific government schemes for portability, but first home buyer grants and stamp duty concessions may still apply when purchasing a new property. Check with your state revenue office, such as Revenue NSW.
