Somewhat appropriately for a home page, Master Advocates are the experts in homes.
Buying them, (Buyers’ Advocacy), Selling them (Vendors’ Advocacy) and Managing them, (Property Management) Since 2014, we’ve been helping people just like you to find or buy their dream home, buy investment properties, upsize, downsize, sell their existing properties, or manage and maintain their properties. We pride ourselves on our ability to take the stress out of what is arguably one of the most stressful events in your life.
How? By taking care of everything for you. The searching, due diligence, research, inspections, auctions, paperwork, negotiating, contracts and all the rest. Basically, all the stuff you hate. And, being second generation licensed estate agents and having been in the real estate business for over 25 years, we like to think we’ve become pretty darn good at it. In fact, you could say we’re the masters.
Buyers’ Advocacy
Buyers’ advocates (also known as Buyers agents) are licensed professionals that specialise in searching, evaluating and negotiating the purchase of a property on your behalf. They take care of all the details including finding a place, due diligence, negotiating, bidding, contracts and much more.
An independent Buyers advocate works exclusively on your behalf and does not accept any sales commissions from vendors, sales agents or developers.
Vendors’ Advocacy
Vendors’ advocates are the specialists you turn to when you want to sell your property.
They take care of every aspect of the sale including background research, finding the right sales agent, valuations and appraisals, negotiations, managing private sales and auctions, documentation and more.
property management
Property management is basically getting someone else to manage your investment property for you, whether you have one investment or a multi property portfolio.
A property manager manages all aspects of the tenancy on your behalf and makes sure that you are maximising the value of your investment.
This includes renter checks, documentation, collection of rent, regular inspections, looking after all repairs, maintenance, improvements and renovations, assessments, safety compliance, residential rental minimum standards, written reports and documentation to be rental ready and much more.

Why You Should Choose Us
The decoy bidder in the check coat: Mark Errichiello
The second of our new faces to have a big impact on the day was buyer’s advocate Mark Errichiello, who appeared to have a client keen on securing at least one of the Island Cove Villa properties.
Known as bidder No. 24, he tick-tacked with other bidders on houses 4 and 3 before eventually dropping out of the race.
It was the auction of House 5 when he finally came out on top after fighting off four other bidders, winning Kristian and Mimi’s property for $2.93 million.
At the conclusion of all the auctions, it was revealed his client was actually Portelli.
So, why did a billionaire need someone to buy his home on his behalf?
“Who knows how it would have worked out if he [Portelli] was just there on his own, buying them all?” Errichiello asked. “Others may have competed with him a little bit more vigorously at times.”
“Portelli waited until after all five auctions had taken place to make his big reveal. The billionaire stunned the crowd when he revealed, post-auction, that he had bought every home on the show, directly or through his buyer’s agent. He also confirmed that he won’t be returning to bid again next season.”…

Mark from Master Advocates was a pleasure to work with. He is well organised, helpful and his communication was excellent — I never had to chase, and he always explained the rationale behind each step. His strategy and instincts were spot on during pre-auction negotiations which helped secure the property ahead of Auction. He was always responsive and moved negotiations along, while keeping expectations realistic and grounded for all parties. I felt well supported and genuinely well represented throughout the process. Highly recommend Mark.Posted on Google![]()

Mark was invaluable throughout the process of buying a home. His expertise was essential to know what to look for, when listings were horrendously underquoted and how to approach offers and bidding. Mark provided us with recommendations for various tradespeople which has helped us to make improvements to the place he secured for us.Posted on Google![]()

I recently had the opportunity after so many years of knowing Mark to actually work with him in a conjunctional sales campaign. Such a pleasure and privilege to be working alongside this ultimate professional. Mark's knowledge of our trade, and vendor communication was second to none, even on the day of the auction his communication and education to a younger purchaser explaining things was refreshing and powerful to watch. I have no hesitation in referring Mark to anyone who is thinking of buying as you will be in the safest, caring hands. Well done mate and I look forward to working again with you very soon!

Mark has been absolutely incredible. Mark found my new home quickly. He was always prompt at communicating and his professionalism/honesty was unmatched. I highly recommend Mark for facilitating your purchase. I would not have been able to get a house as a first home buyer without his help.Posted on Google![]()

Thank you Mark for your professional, knowledgeable and responsive manner. From our very first conversation, you demonstrated deep market knowledge, clear communication, and genuine care for my goals. Despite the distance, I always felt informed and supported. Your attention to detail and proactive updates gave me peace of mind in what wasn’t the most straightforward sale. What truly stood out was your commitment to going above and beyond. I would highly recommend Mark to anyone looking to sell their property—especially if you're doing it from afar.
