Refinancing multiple properties means restructuring more than one loan at the same time to access equity, reduce interest rates, or align your debt with where your business is heading.
If you own a home and an investment property in Sydney, or you've built a small portfolio over the years, the decision to refinance isn't just about swapping one loan for another. It's about coordinating debt across properties so each loan works harder for you. That might mean releasing equity from your owner-occupied home to fund a business expense, moving to a variable rate on one property while locking in a fixed rate on another, or consolidating loans to improve cashflow.
Why refinance more than one property at the same time
Refinancing multiple properties together lets you see your total debt position and make decisions based on the whole picture, not just one loan in isolation.
Consider a sole trader who owns a home in Marrickville and an investment unit in Parramatta. The home loan is on a variable rate at 6.2%, the investment loan is coming off a fixed rate period and reverting to 6.8%. Refinancing both at once might mean moving the investment loan to a lower variable rate while adding an offset account to the home loan. The valuation process happens simultaneously, the application is lodged as a package, and the outcome is a coordinated structure that reflects how the properties actually work together in your financial life.
When you refinance separately, lenders assess each application without full visibility of your other commitments. When you refinance together, the lender sees your entire position and can price accordingly. In some cases, that means accessing a lower interest rate or waiving fees because the total loan amount is larger.
How lenders assess multiple property refinances
Lenders evaluate your ability to service all loans combined, not each property in isolation.
Your borrowing capacity is calculated using your declared income, rental income from investment properties, and all existing debts including credit cards, car loans, and the new loan amounts you're applying for. If you're a sole trader, lenders typically require two years of tax returns and a recent notice of assessment. They apply a serviceability buffer, usually around 3% above the actual interest rate, to ensure you can manage repayments if rates rise.
Rental income is assessed at 80% of the actual rent to account for vacancy and maintenance costs. If your Parramatta unit generates $650 per week in rent, the lender will use $520 per week in their serviceability calculation. This is why sole traders with variable income need to show consistent earnings over time. A strong tax return from two years ago won't offset a weaker result last year.
Structuring loans across owner-occupied and investment properties
Your owner-occupied home loan and investment loan should be structured differently because they serve different purposes and have different tax implications.
Interest on an investment loan is tax-deductible, so many sole traders prefer to keep that loan interest-only or on a variable rate with an offset account. The offset account holds business income or savings, reducing the interest charged on the investment loan while keeping those funds accessible. Interest on your home loan is not deductible, so the priority is often to pay down that loan faster using a principal and interest structure.
In a scenario where you're refinancing both, you might move your home loan to a lower rate with extra repayment flexibility and structure the investment loan to maximise deductible interest. This approach separates personal and investment debt clearly, which matters at tax time and when you're planning the next property purchase.
Accessing equity across multiple properties for business use
If you need to access equity to invest in your business, buy equipment, or fund another property deposit, refinancing multiple properties can release that equity in a structured way.
Equity is the difference between what your property is worth and what you owe. Lenders will typically let you borrow up to 80% of a property's value without paying lenders mortgage insurance. If your Marrickville home is valued at $1.2 million and you owe $600,000, you have $600,000 in equity. At 80% loan-to-value ratio, you could borrow up to $960,000, meaning you could access up to $360,000 by refinancing.
Releasing equity from one property while refinancing another lets you consolidate the process. You lodge one application, complete one valuation round, and settle both loans at the same time. The funds can be drawn down into an offset account or released as cash depending on how the loan is structured.
When to refinance investment properties separately from your home
There are situations where refinancing investment properties independently makes more sense, particularly if your home loan is already on a competitive rate or you're planning to sell one property soon.
If your owner-occupied loan was refinanced recently and you're still within a competitive rate range, you might only refinance the investment property. This avoids discharge fees on the home loan and keeps the application focused on the property that needs attention. Similarly, if one investment property is underperforming or you're considering selling within the next 12 months, refinancing that loan separately keeps your options open without locking other properties into a new loan term.
Sole traders with fluctuating income should also consider timing. If your most recent tax return shows lower income due to business reinvestment or deductions, waiting until after the next assessment might strengthen your serviceability. In that case, you could refinance one property now and the other once your income position improves.
Coordinating fixed rate expiry across multiple loans
If you have fixed rate loans ending at different times across multiple properties, you can either refinance each loan as it expires or bring them all onto the same lender at once.
Many property owners locked in fixed rates between late 2020 and mid 2022 at rates between 2% and 3%. Those fixed rate periods are now ending, and revert rates are often above 6%. Refinancing as each loan expires means you're always monitoring rates and lender offers. Refinancing all properties together when the first fixed rate ends can simplify your position, especially if you're moving to a lender that offers portfolio pricing or relationship discounts.
The downside of refinancing everything at once is that you might exit a fixed rate early on one property and incur break costs. Those costs depend on the remaining term and the difference between your fixed rate and current wholesale rates. Before committing, ask the lender to calculate break costs and compare them to the interest savings you'll achieve by moving all loans to a lower rate.
How the refinance process works for multiple properties
The refinance application for multiple properties follows the same steps as a single loan, but with additional documentation and valuation requirements for each property.
You'll need to provide proof of income, recent tax returns, rental statements for investment properties, current loan statements, and details of other debts. The lender will order valuations for each property, either desktop or physical depending on the property type and location. In some Sydney suburbs, particularly in the Inner West and Eastern Suburbs, lenders are more likely to require physical valuations if recent sales data is thin.
Once the application is approved, the lender will issue a formal loan offer covering all properties. You'll review the terms, sign the documents, and the new lender will arrange settlement with your existing lender. Settlement happens on the same day for all loans if they're with the same outgoing lender, or staggered by a few days if they're with different lenders. Your solicitor or conveyancer will manage discharge and registration, and you'll start making repayments to the new lender from the following month.
Should you consolidate all properties with one lender or split them
Consolidating all loans with one lender simplifies management and may unlock relationship pricing, but splitting loans across lenders can give you flexibility and competitive tension.
If you consolidate, you'll have one point of contact, one online portal, and the potential for fee waivers or rate discounts based on total loan size. Some lenders offer portfolio home loans designed for property investors and sole traders, which include features like shared offset accounts and flexible redraw. This structure works well if you want clarity and minimal administration.
Splitting loans across lenders means you're not locked into one institution if your circumstances change. If one lender increases rates or removes a feature, you can refinance that loan without touching the others. You also maintain borrowing capacity with multiple lenders, which can be useful if you're planning to access equity for investment or expand your portfolio. The trade-off is more admin and less leverage when negotiating rates.
Offset accounts and redraw facilities across multiple loans
Offset accounts and redraw facilities both reduce the interest you pay, but they work differently and matter more when you're managing multiple properties.
An offset account is a transaction account linked to your loan. The balance in the offset account reduces the loan balance used to calculate interest. If you have a $500,000 loan and $50,000 in your offset account, you only pay interest on $450,000. Offset accounts are particularly useful for sole traders because you can park business income, tax savings, or unallocated funds and reduce interest without losing access to the money.
Redraw lets you withdraw extra repayments you've made on a loan. It's common on investment loans, but the lender controls access and can change redraw terms. If you're relying on redraw to access funds for a business expense or deposit, check the lender's policy before refinancing. Some lenders have removed or restricted redraw in recent years, particularly on fixed rate loans.
When refinancing multiple properties, consider whether each loan needs an offset account or whether redraw is enough. Offset accounts sometimes come with higher interest rates or annual fees, so if you're not going to use the account actively, it might not be worth the cost.
Tax implications when refinancing investment properties
Refinancing an investment property can affect your tax deductions, particularly if you increase the loan amount or consolidate personal debt into the investment loan.
Interest on borrowings used to purchase or improve an income-producing property is deductible. If you refinance to access equity and use that equity to buy another investment property or fund business operations, the interest on the additional borrowing is also deductible. If you use the equity for personal purposes, such as renovating your home or buying a car, that portion of the interest is not deductible.
This is why loan structure matters. If you refinance your investment property and draw down $100,000 in equity, that $100,000 should be split into a separate loan account if it's being used for a different purpose. Your accountant will need a clear record of how the funds were used to ensure you're claiming deductions correctly.
Working with a broker to coordinate multiple property refinances
Coordinating the refinance of multiple properties involves matching loan structures to your income, tax position, and what you're planning to do next, which is where a broker adds the most value.
A broker will review your current loans, calculate your equity position, assess your serviceability, and identify lenders that suit your situation. If you're a sole trader with two years of solid tax returns and rental income from an investment property, the broker can approach lenders that price competitively for that profile. If your income is variable or you've recently changed your business structure, the broker will know which lenders assess sole traders more flexibly.
The broker also manages the application process across multiple properties, ensuring valuations are ordered at the right time, documents are submitted in the correct format, and settlement is coordinated so you're not left without access to funds between loans. If you're planning to release equity to buy the next property, the broker will structure the refinance so the equity is available when you need it, not tied up in a redraw facility you can't access quickly.

Frequently Asked Questions
Can I refinance multiple properties at the same time?
Yes, you can refinance multiple properties together by submitting a single application that covers all loans. This approach lets lenders assess your total debt position and may result in portfolio pricing or lower rates based on the combined loan amount.
How do lenders assess serviceability for multiple property refinances?
Lenders calculate your ability to service all loans by combining your declared income, rental income at 80%, and all existing debts. For sole traders, they typically require two years of tax returns and apply a serviceability buffer around 3% above the actual interest rate.
Should I keep all my property loans with one lender or split them?
Consolidating with one lender simplifies management and may unlock relationship discounts. Splitting loans across lenders gives you flexibility and competitive tension, so you can refinance individual properties without affecting the others.
Can I access equity from multiple properties when refinancing?
Yes, refinancing multiple properties lets you release equity from one or more properties in a coordinated way. Lenders typically allow you to borrow up to 80% of each property's value, and the equity can be used for business, investment, or another property deposit.
What happens if my fixed rate loans expire at different times?
You can either refinance each loan as it expires or bring all properties onto the same lender when the first fixed rate ends. Refinancing together may involve break costs if you exit a fixed rate early, so compare those costs to the interest savings before proceeding.
