About Marika
18 years experience Having lived and worked in Mount Gambier for nearly 20 years, I love the area and am proud of the knowledge and connections I’ve developed within the local community. Having been a highly successful sales agent since 2004, I went one step further and set up my own agency, Complete Real Estate. As Mount Gambier has evolved over the past decade, so has Complete Real Estate. We launched with personal referrals and have now become a highly sought after team. Today, we look after a large number of clients, at any given time, with their investment properties and home sales. Our ‘family’-style operation is a perfect fit with Mount Gambians’ down-to-earth values. We are finely attuned to the sensitivities that surround all types of property transactions and enjoy working with clients through all stages of the property process. Staff are encouraged to share their market intel with each other so we can continually improve and refine our approach. With customer experience a vital component of our business’s difference, my goal is to ensure that staff are given the time and freedom required to put the interests of our clients front and centre. Each property team in our real estate agency works in unison, ensuring an integrated approach is taken whether we are helping you to lease, manage or sell a home. Complete Real Estate is well-known for its approachable staff, streamlined operations and complete transparency. Our collective ethos is to achieve the very best result for every property with which we work. My team and I are excited about the long-term opportunities for growth in Mount Gambier. Our combined expertise in sales and property management gives us unique insights into the history of each and every property, and the future of this thriving region. Call me today to discuss your property needs and you’ll be guaranteed to receive a warm welcome!

Nathan and the Team at Complete Real Estate are the Go Too Team if you want to sell/buy a home

Nathan Hayward at Complete Real Estate, Mount Gambier is not only a very professional, effecient and effective agent but with his warm personality, he took on the sale of my house with ease. With the support of the team at Complete, Nathan was able to be keep me informed of the progress of the sale at every stage. This not only gave me complete peace of mind but it allowed me the ability to focus on other important matters whilst the sale progressed. From the start, I knew that I had chosen the right Real Estate Agent and Agency to look after every part of such a big decision (the sale of one's home). I highly recommend Nathan and Complete Real Estate to anyone thinking of selling or buying a home in Mount Gambier.
