Our Services
Personal Finance
Whether you’re planning a wedding, consolidating debt, or funding a personal project, the right loan can make all the difference. We look beyond the banks to find flexible personal finance solutions with competitive rates that fit your budget. Our team helps you secure the funds you need quickly, with a simple and streamlined process from start to finish.
Refinancing
Your financial situation evolves, and your home loan should too. We specialise in reviewing your current mortgage to ensure it’s still working hard for you, potentially saving you thousands by securing a lower interest rate or better features. Let us handle the market comparison and paperwork to unlock your home's equity or simply reduce your monthly repayments.
Pre-Approval & Purchasing
Enter the property market with confidence. We guide you through the entire purchasing journey, starting with a solid pre-approval that defines your budget and strengthens your negotiating position. From making an offer to final settlement, our Adelaide-based team is by your side, ensuring a seamless and stress-free path to owning your new property.
Asset Finance
From a new vehicle for your business to equipment that drives growth, we make asset acquisition simple and affordable. We leverage our extensive network of lenders to find competitive financing for cars, machinery, and commercial vehicles. Our team structures the finance to protect your cash flow and align with your business or personal goals.
Commercial Funding
Financing commercial property requires specialised expertise and access to the right lenders. Whether you’re purchasing an office, a retail space, or an industrial warehouse, our specialists navigate the complexities for you. We structure tailored funding solutions that maximise your return on investment and support your long-term commercial strategy.
Business Finance
Fuel your business's growth and manage your day-to-day operations with the right financial support. We go beyond standard loans to provide a range of solutions, including working capital, overdraft facilities, and invoice financing. Let us find a flexible and strategic funding solution that helps your business thrive in a competitive market.
Private Lending
When unique circumstances or tight deadlines require a solution outside of the major banks, private lending can provide the answer. Our team has cultivated strong relationships with a network of private lenders to facilitate fast, flexible funding for complex property transactions and short-term needs. We specialise in finding creative solutions when traditional finance isn't the right fit.
Construction Loans
Financing the construction of a new property involves a specialised process of staged payments and lender requirements. Our team are experts in managing construction loans from start to finish. We handle the entire process, from structuring the initial finance to coordinating progress draws with your builder, ensuring a smooth and timely build.

Sergio and the team were exceptional to work with on our first home loan. Looking at buying our first home felt overwhelming, but Sergio took time to answer all of our questions and help us along the journey so we felt comfortable and confident the whole way through. I was actually surprised (and very grateful) by how easy Sergio made everything for us. Without hesitation, I would feel confident coming back to Sergio and the team in the future!

I recently had a great experience working with Steffan as my finance broker, and I couldn't be more satisfied. After two unsuccessful attempts at refinancing our multiple loans, Steffan stepped in and secured fantastic financial outcomes for us and made the entire process efficient and straightforward. Steffan was easy to work with and I highly recommend his services to anyone looking for a reliable and knowledgeable finance broker.

Outstanding service by Brokerage and Co. I immediately felt at ease working with Sergio as no question was too much and no call was ever a bother. His response time reflected his work ethic and passion for helping families achieve their goals. Shout out to Nikola as well for the enthusiasm and prompt responses. They've fast tracked our goals and we look forward to continuing working with them

Sergio is very knowledgeable, responsive and a delight to deal with. I have confidently told family and friends what a great broker he is, and sometimes they had seen other brokers and they all said the same thing: “wow, Sergio is so much better than my old broker!”. I look forward to working with Sergio for my finance needs for many years to come.

Sergio and the team were ready to answer any question at any time. I would highly recommend Sergio to anyone looking for a broker!

The thought of ever owning a property, or applying for a home loan had always been so daunting for me but Fedi made the whole process so easy and was very patient and explored so many options to make it all happen. Fedi’s professionalism is demonstrated through his guidance and effective communication skills. Couldn’t have asked for a better mortgage broker!
