Property Investment Loans | Double Bay Mortgage Broker

Growing Your Property Investment Portfolio in Double Bay

Expanding your property investment portfolio is one of the most effective ways to build wealth over the long term. Whether you already own one investment property and are looking to add another, or you have a growing portfolio and want to keep the momentum going, the right investment loan structure makes all the difference. At Double Bay Mortgage Broker, we work with property investors across Double Bay and beyond to access investment loan options from banks and lenders across Australia.

Understanding your borrowing position

Before adding to your portfolio, it helps to understand where you stand financially. Lenders assess your investment loan application based on a range of factors, including your income, existing debts, the loan to value ratio (LVR) on your current properties, and the rental income each property generates. Under current APRA guidelines, lenders apply a serviceability buffer of 3 percentage points above the product rate when assessing your ability to repay. This means your borrowing capacity may be lower than you expect, particularly if you already hold multiple loans.

The debt-to-income (DTI) cap introduced in February 2026 also affects how lenders approach investor borrowing. Authorised deposit-taking institutions can now fund only up to 20 per cent of new investor loans at a DTI of 6 times or greater. This does not mean borrowing above that threshold is impossible, but it does mean lenders apply closer scrutiny. Double Bay Mortgage Broker helps you understand how these settings affect your position before you apply.

Using equity to grow your portfolio

Many investors looking at expanding their property investment portfolio already hold equity in existing properties. Equity release allows you to leverage equity built up in your home or investment properties to fund a deposit on the next purchase, reducing the need for additional cash savings. This is one of the most common strategies used by experienced investors to achieve portfolio growth without waiting years to save a fresh deposit.

The amount of equity you can access depends on your current property values, your outstanding loan balances, and the LVR limits set by your chosen lender. Lenders Mortgage Insurance (LMI) may apply if your borrowing takes the LVR above 80 per cent, though some lenders offer LMI waivers for eligible borrowers. Our team at Double Bay Mortgage Broker can walk you through the numbers so you know exactly what is available to you.

Choosing the right loan structure

Expanding your property investment portfolio requires careful thought about loan structure. Many investors choose interest only investment loans to keep repayments lower in the short term and maximise tax deductions on claimable expenses such as interest costs. Others prefer principal and interest repayments to reduce debt over time. A variable rate gives you flexibility to make extra repayments or refinance, while a fixed interest rate provides certainty over your repayment amounts for a set period.

The right choice depends on your property investment strategy, your cash flow, and how you plan to manage the portfolio over time. Double Bay Mortgage Broker compares investment loan products across a wide panel of lenders so you can weigh up the investment loan features and investment loan benefits that matter most to your situation.

The Simple Steps

Initial Consultation

Your journey begins with a conversation about your property goals - whether you're purchasing a home, investing, refinancing, or seeking another type of loan. Our Finance & Mortgage Brokers explain the overall loan application process, assess your financial position, and begin identifying suitable loan options from a wide panel of banks and lenders across Australia.

Financial Assessment

Your broker conducts a detailed review of your finances, including income, expenses, assets, liabilities and savings. They determine your borrowing capacity and explain key terms like loan-to-value ratio (LVR), lenders mortgage insurance (LMI), and any government schemes or discounts you may be eligible for.

Loan Comparison & Selection

With a clear understanding of your financial situation, our Finance & Mortgage Brokers research and compare a range of loan options. These may include fixed or variable interest rate loans, products with offset accounts, or flexible repayment features. Our brokers help you weigh the pros and cons of each loan, ensuring you choose the one that aligns best with your needs and preferences.

Loan Pre-Approval

Securing loan pre-approval provides a clear idea of how much you can borrow and strengthens your position in the property market. Your broker prepares and submits the required documents - such as payslips, tax returns, and bank statements - to the lender for assessment. Pre-approval also gives you confidence to make offers when you find the right property.

Formal Loan Application

Once you've chosen your preferred loan, your broker completes and submits the formal application to the lender. They manage all required documentation, respond to any queries from the lender, and keep you informed throughout the process to avoid unnecessary delays.

Loan Approval & Settlement Preparation

After your loan is formally approved, our brokers review the loan agreement with you and confirm that all terms - such as interest rate, fees, and repayment schedule - are clear and understood. They also help you set up your loan account and arrange any necessary insurance, such as mortgage or home loan protection.

Settlement & Ongoing Support

At settlement, the lender advances the funds and ownership of the property is transferred to you. Our brokers coordinate with your solicitor or conveyancer to ensure everything runs smoothly. After settlement, our Finance & Mortgage Brokers remain available for ongoing support - whether it's managing repayments, exploring refinancing opportunities, or helping with future property plans.

Key Considerations When Expanding Your Portfolio

Expanding your property investment portfolio involves more than finding the right property. The finance behind each purchase needs to work as part of a broader strategy, and that requires understanding how each loan interacts with the others.

Rental income and vacancy rates

Lenders take rental income into account when assessing your investment loan amount, but they do not always use the full rental figure. Most lenders apply a discount to account for vacancy rates and ongoing costs such as body corporate fees, rates, and maintenance. Understanding how lenders treat rental income helps you set realistic expectations around how much you can borrow for your next property investment loan.

Tax considerations for investors

Property investors in Australia have historically been able to offset rental losses against other income through negative gearing benefits. However, the tax landscape is changing. Under the Treasury Laws Amendment (Tax Reform No. 1) Act 2026, properties acquired on or after 7:30pm AEST on 12 May 2026 will face new rules from 1 July 2027. Net rental losses from residential dwellings that are not eligible new builds will be quarantined, meaning those losses can only be offset against other residential rental income or carried forward. They cannot be offset against salary or wages. Properties held before that date continue under existing rules. Eligible new residential dwellings, including those built on previously vacant land or those that increase dwelling numbers, retain access to negative gearing under the new framework. Changes to capital gains tax treatment also apply from 1 July 2027, replacing the 50 per cent CGT discount with cost base indexation and a minimum 30 per cent tax rate on real capital gains for affected assets. These are significant changes that affect how investors approach property investment strategy. Double Bay Mortgage Broker is not a tax adviser, but we work alongside your accountant or tax professional to ensure your loan structure supports your broader financial goals.

Stamp duty and upfront costs

Each new property purchase comes with upfront costs, and stamp duty is typically the largest. These costs affect how much deposit you need and how much you may need to draw on equity from existing properties. Planning for these costs early helps avoid surprises during the investment loan application process.

Investor interest rates and rate discounts

Investment property rates are generally higher than owner-occupier rates. However, investor interest rates vary significantly between lenders, and there is often room to negotiate a rate discount, particularly for borrowers with strong equity positions and clean credit histories. Double Bay Mortgage Broker compares investor rates across our lender panel to help you find a competitive investment loan interest rate. If you already hold investment loans, it may also be worth exploring investment loan refinancing to see whether a better rate is available.

Building wealth through property takes time and a clear plan. Double Bay Mortgage Broker is here to help residents in Double Bay structure their investment loan options in a way that supports long-term passive income and financial freedom.

Hear From Our Clients

Our Client Reviews

Nick and the team at Azura Financial exceeded our expectations at every step. Their guidance was clear, their expertise was evident, and they handled every financial detail with care — giving us complete peace of mind throughout the process. We couldn't have asked for a better team by our side. Thank you very much, V&V.

Van Tran

As a founder, getting a mortgage requires a couple more hoops to jump through, which is why I couldn't recommend Nick O'Sullivan and the Azura team more highly. Not only were they able to offer a seamless process, but Nick was also patient with us as we changed our minds about when to buy (over a period of years!). The truth is anyone can approach a bank and get a mortgage, but when things don't go perfectly (e.g. abrupt government changes), that's when you want a pro on your team like Nick.

Shaun Cunningham

As a first home buyer, Carl and the team at Azura were incredibly helpful throughout the whole process. They made everything feel straightforward and were always there to answer any questions along the way. I’ve already recommended them to friends and would highly recommend them to anyone looking to get a mortgage!

Frequently Asked Questions

Why choose Double Bay Mortgage Broker over a broker based elsewhere?

Choosing a local broker means working with someone who genuinely understands the Double Bay area, the types of properties here, and the people who live and invest in this community. We are not a call centre or a faceless online service. We are a local business that takes pride in building real relationships with our clients. When you work with Double Bay Mortgage Broker, you get personalised service from someone who is invested in your outcome. We are accessible, we communicate clearly, and we are here for the long term. Many of our clients come back to us when their circumstances change, and that kind of ongoing relationship is something we value deeply.

Can Double Bay Mortgage Broker help if I am self-employed?

Yes, we work with self-employed clients regularly. Getting a home loan when you are self-employed can be more involved than a standard application because lenders assess income differently for business owners. Some lenders require two years of tax returns, while others offer what are known as low-doc loans, which require less documentation but may come with different conditions. At Double Bay Mortgage Broker, we understand how to present a self-employed application in a way that gives it the strongest possible chance of being assessed fairly. We will take the time to understand how your income works and match you with lenders who are well suited to your type of borrowing situation.

What documents will I need to provide?

The documents required will depend on your individual circumstances, but as a general guide, most lenders will want to see proof of identity, recent payslips or tax returns, bank statements, details of any existing debts or liabilities, and information about the property you are looking to purchase or refinance. If you are self-employed, you may need to provide additional documentation such as business financial statements or BAS statements. At Double Bay Mortgage Broker, we will give you a clear checklist of what is needed for your specific situation so you are not scrambling to pull things together at the last minute. Being organised early can help keep the process on track.

How long does the home loan process take?

The timeline can vary depending on a number of factors, including the lender you go with, the complexity of your application, and how quickly documents are provided. In general, once we have everything we need from you, a straightforward application can take anywhere from a few days to a few weeks to receive formal approval. At Double Bay Mortgage Broker, we work to keep things moving as efficiently as possible and keep you updated along the way. We know that waiting for news on something as important as a home loan can be stressful, so we make it a priority to stay in regular contact and answer your questions promptly.

What is refinancing and how do I know if it is worth looking into?

Refinancing means replacing your existing home loan with a new one, either with your current lender or a different one. People refinance for a number of reasons, including accessing equity in their property, consolidating debts, changing their loan structure, or simply reviewing whether their current loan still suits their needs. At Double Bay Mortgage Broker, we can review your existing loan and compare it against what else is available in the market. We will give you an honest assessment of whether refinancing makes sense for your situation. There are costs involved in refinancing, such as exit fees or application fees, and we will make sure you understand these before making any decisions.

I am a first home buyer. Can Double Bay Mortgage Broker help me?

Absolutely. Buying your first home is one of the biggest financial decisions you will ever make, and it can feel overwhelming when you are not sure where to start. At Double Bay Mortgage Broker, we work with first home buyers regularly and understand the questions and concerns that come with it. We will walk you through the process from start to finish, explain the different loan options available to you, and help you understand what government grants or schemes you may be eligible to apply for, such as the First Home Owner Grant. We want you to feel informed and confident at every stage, not left in the dark.

What types of loans can Double Bay Mortgage Broker help with?

We help clients with a wide range of lending needs. This includes home loans for owner-occupiers, investment property loans, refinancing existing loans, construction loans, and loans for self-employed borrowers. We also assist with commercial finance and asset finance depending on your situation. Whether you are buying your first home in Double Bay, looking to grow a property portfolio, or wanting to review your current loan to see if there is a more suitable option out there, we are here to help. Every client has a different set of circumstances, and we take the time to understand yours before recommending any course of action.

How much does it cost to use Double Bay Mortgage Broker?

In most cases, our service comes at no direct cost to you. Mortgage brokers in Australia are typically paid a commission by the lender once a loan settles. This means you can access our knowledge and support without paying out of pocket. We are upfront about how we are paid and will always explain this to you clearly before we get started. There are some situations where a fee may apply, and if that is the case, we will let you know well in advance so there are no surprises. Transparency is something we take seriously at Double Bay Mortgage Broker.

Why should I use a mortgage broker instead of going directly to my bank?

When you go directly to your bank, you only see what that one lender has to offer. A mortgage broker like Double Bay Mortgage Broker has access to a broad panel of lenders, which means we can present you with a wider range of options. Your bank is focused on selling its own products, whereas we are focused on finding the right fit for your circumstances. We also know how different lenders assess applications, which means we can help you put your best foot forward. For residents in Double Bay, having someone local who understands the property market in this area can make a real difference.

What does a mortgage broker actually do?

A mortgage broker acts as the go-between for you and a range of lenders. Rather than you having to approach each bank or lender on your own, a mortgage broker does the legwork for you. At Double Bay Mortgage Broker, we look at your financial situation, understand what you are trying to achieve, and then search through a wide panel of lenders to find options that suit your needs. We handle the paperwork, liaise with lenders on your behalf, and guide you through each step of the process. It is our job to make sure you understand what you are signing up for before you commit to anything.
