Experienced Agent

Kathleen was easy to deal with. Her experience and knowledge of realestate around the Newcastle Lake Macquarie area was very helpful. Kathleen allows plenty of time at private viewings, enabling prospective buyers to consider all options.

Kathleen was a delight for us to work with and communication was first class

Kathleen’s agency were unreal and the vendors were very lucky to engage them because we had a horrible experience when selling our house in Sydney. They were the total opposite from what we experienced selling Kathleen was honest, knowledgeable about what she was selling, trustworthy and a pleasure to work with

Exceptional- Above & Beyond In Every Way

I couldn’t have asked for anything more from my real estate agent. From the very beginning, Kathleen’s intuition and ability to understand my needs were exceptional, combined with outstanding attention to detail throughout every stage of the process. What truly set her apart was her ability to connect with prospective buyers on a personal level, creating genuine engagement and understanding rather than simply facilitating a transaction. Her unique knowledge and understanding of the Valentine community was invaluable and clearly contributed to an outstanding result. Kathleen’s professionalism, communication, care and commitment was exemplary. She is the epitome of best practice in real estate and went above and beyond in every respect. I am incredibly grateful for the way my sale was handled and would have no hesitation in recommending Kathleen Matinlassi to anyone looking for an exceptional agent. Couldn’t ask for anything more!

Who would have thought selling would be such a smooth process

We cannot thank Kathleen and her team enough who recently sold a property for us. From our initial meeting we felt like we were in the best hands. Kathleen's knowledge and genuine love of the local area was so reassuring. Communication was on point, updates so prompt. Happy to say we sold in a very quick time frame. Would highly recommend Kathleen, such an easy agent to deal with and nothing was ever an issue

Honest, respectful, informative and genuinely understanding.

We can't thank Kathleen Matinlassi enough for helping us purchase our dream home. From the very beginning, she listened to what was important to our family, knew we were ready to buy, and worked with us to help make it happen. When we walked through the front door, we instantly knew as a family it was the one. Kathleen made the buying process smooth and stress-free with her honest communication, prompt follow-up and genuine care. She was respectful to both parties throughout the entire process, which really stood out to us. It was the little things that made a difference too, like taking the time to ask our children's names. It showed she genuinely cared about the people, not just the sale. We're so grateful to Kathleen for making the purchasing process such a positive experience for our family, and we highly recommend her to anyone looking for a professional real estate agent who just really cares and wants to help your family secure your new home.
