My client stories
Sonja has been a breath of fresh air since the beginning, always punctual and knows the ins and out of the homes she sells, as if she is selling her own home.... There is never any questions unanswered, we viewed one house in one day and fell in love with the house because of her warm knowledge. Thank you Sonja!

She handled everything smoothly and made what could have been a stressful experience feel easy and well-managed. I would highly recommend Sonja to anyone looking for a reliable and trustworthy property professional.

Mrs Zinhle Nompumelelo Nonfundo Mnguni
Sonja is the hardest working agent I have come across. She really became deeply invested in selling our property and did her best for us at every turn. Most important for me was her punctuality and the fact that she honoured every appointment she made for a viewing .Her communication with us was frequent and informative. She did a great job and found our buyer!
Mr Dennis Richard Ryder
my sincere appreciation for the exceptional service and unwavering dedication shown by Sonja Egglestone in the sale of our property. More than two and a half years ago, Sonja was the very first agent to sign our home. In hindsight, bringing additional agents on board was unnecessary on my part, because throughout this entire journey Sonja consistently demonstrated a level of commitment seldom seen in this industry. Even when our property was taken off the market, she never lost heart. She returned, followed up, and continued to believe in the home and in the process. In the end, she was the one who sold it, exactly as she had set out to do from the beginning. What stands out most is not only her professionalism, but her perseverance, her honesty, and the calm, steady light she brings into what is often a very difficult environment. Her approach is refreshing, her work ethic is remarkable, and her character speaks louder than any sales result ever could. Sonja has been a blessing to us throughout this process. I hope she is valued within your organisation as highly as we value her, because she represents your brand with excellence, integrity, and heart. Her light shines bright in an industry where many grow weary, and it is clear she carries that strength into every client relationship. Thank you for having someone of her calibre on your team. She has made this journey not only successful, but genuinely meaningful.

Mr Darryl Graham Wilcock
I cannot recommend my estate agent, Sonja Egglestone, highly enough. From the very beginning, her service was exceptional, and I was extremely happy with the way she handled the sale of my property. It was not an easy or quick sale, and the property took considerably longer to sell than we had originally hoped. Throughout that entire period, however, she never lost enthusiasm or gave up. She remained positive, determined and completely committed to finding the right buyer. Her dedication and work ethic were truly remarkable. She worked incredibly hard, was always available when I needed assistance, and kept me informed throughout the process. No question or request was ever too much trouble for her. She was consistently friendly, patient, helpful and professional, and always willing to go the extra mile. What impressed me most was her perseverance. Even when months passed without a successful sale, she simply kept working, following up, arranging viewings and looking for new opportunities. I always felt that selling my property genuinely mattered to her and that I was more than just another client. Selling a property can be a stressful experience, particularly when it takes longer than expected, but having someone so dependable and dedicated made an enormous difference. I am extremely grateful for everything Sonja did for me and for the effort she put into achieving a successful sale. Her service exceeded my expectations, and I would recommend her without hesitation to anyone looking for an estate agent who is hardworking, trustworthy, professional and genuinely cares about her clients. Thank you for an outstanding job and for never giving up!
Mr Cornelius Johannes Abraham Pieterse
We had the pleasure of working with Sonja Egglestone during the purchase of our home, and we cannot recommend her highly enough. From the very beginning, she demonstrated exceptional professionalism, deep market knowledge, and genuine care for our needs. She guided us through every step of the process with patience and clarity, ensuring we understood all the details before making decisions. Her responsiveness was outstanding—always available to answer questions and provide updates promptly. What impressed us the most was her ability to negotiate effectively while keeping our best interests at heart. Thanks to her dedication, the entire process was smooth, efficient, and far less stressful than we anticipated. I am truly grateful for her support and expertise.
