Navigating Home Loan Portability: How to Transfer Your Mortgage When You Move

Selling your current home and buying a new one can be exciting, but it also involves juggling multiple financial decisions. One option that’s often overlooked is home loan portability, which allows you to transfer your existing mortgage to a new property. This can be a smart alternative to refinancing, helping you save on fees, time, and effort during your move.

In this blog, we explain what loan portability is, how it works, and whether it’s the right strategy for your next property move.

What Is Home Loan Portability?

Home loan portability lets you transfer your existing mortgage—including the interest rate, terms, and features—to a new property. Instead of closing your current loan and applying for a brand-new one, your lender simply moves the mortgage from your old property to your new one.

This process is generally quicker and more cost-effective than refinancing, especially if you’re happy with your current lender and loan terms.

How Does It Work?

Here’s how a typical loan portability process looks:

You sell your current property.
You buy a new property, often simultaneously or shortly after.
Your lender pays out the old loan using the sale proceeds.
The same loan is then secured against the new property.

This is often referred to as a substitution of security. You may also need to pay a portability fee (usually modest) and meet the lender’s conditions.

Benefits of Home Loan Portability

Save on time and paperwork: No need to complete a full refinance application.
Avoid break costs: Especially useful if you’re on a fixed-rate loan that would normally incur early exit fees.
Keep your existing loan features: Retain access to your current offset account, redraw facility, or interest rate.
No need for credit reassessment: In some cases, your financial situation doesn’t need to be reassessed, simplifying the process.

Things to Consider Before Choosing Portability

While loan portability can offer convenience, it’s not suitable for everyone. Here are a few points to weigh up:

1. Timing Is Crucial

Most lenders require the sale and purchase to happen at the same time (or within a short window). If there’s a delay between selling your current home and buying the next, portability may not be possible.

2. Property Value Differences

If your new home is more expensive, you may need to increase your loan amount, which could trigger a full reassessment. On the other hand, if you’re downsizing, you’ll still need to meet your lender’s minimum loan limits.

3. Loan Terms May Still Change

While you keep the loan account, some elements—like LVR (loan-to-value ratio), fees, or lender conditions—may change, depending on the new property.

4. Not All Loans Are Portable

Some fixed-rate or basic loan products may not allow portability. Always check with your lender or broker before making assumptions.

Is Loan Portability Right for You?

You might consider home loan portability if:

You’re happy with your current interest rate and lender
You’re moving from one property to another within a short timeframe
Your loan features (like offset or redraw) are valuable to retain
You want to avoid the costs and delays of refinancing

However, if you're planning a major change, like accessing equity, changing your loan structure, or switching to a better deal, refinancing might be a better option.
