From the start I felt that John was working in my best interests. He was very knowledgeable about the local property market and this was certainly exhibited in his approach to marketing the property. I believe he exhausted every contact he had to let them know the property was for sale. John established an easy rapport from the start, was pleasant to deal with and kept me well informed about open house attendances. The whole process was stress free which was much appreciated. I would have no hesitation in recommending John Kastellorios to anyone who would want to sell their property

Having dealt with John Kastellorios for some ten years I felt very confident in placing my property sale with him. John has seen the booms and busts of the Sydney real estate market but his advice and professional conduct has always been consistent, realistic and fair to all parties regardless of the market pressures in play.

John was professional throughout the entire campaign. Auction went smoothly with a result we were very happy with. John’s communications skills are excellent. I’d recommend John as an agent to my friends and family.

We first approached John to ascertain his understanding of our particular type of property in our area with a brief face to face, from here he made us feel comfortable and from there we went ahead with engaging him to sell our property. From the very start we were kept up to date of both feedback on our property from the buyers perspective and where John thought our sale was heading. We received a price that was acceptable to us without any high end selling from John that gave us any expectation that was not able to be realised. My wife and I would recommend John if you need an honest broker of your property.

John and his team were an absolute pleasure to work with for the sale of our property. John was very honest from the beginning in helping us to understand the market and in setting expectations. He kept us informed regularly and was professional at all times. I am very glad to have trusted John and his expertise.

From the first time we met with John, we were impressed with his professional and most helpful advice on preparing to sell our home. The amount of time and special effort he put into finding the buyer speaks volumes for the man. John's knowledge and sales skills are to be admired and we would highly recommend him to anyone looking for the best.

The sale of our property has been one of the most stressful times of our lives. We used another agent for 6 months and were very disappointed with the outcome. When we decided to use John's services, his strategies, communication, capabilities, network support and approachability was first class. He made us feel comfortable despite the stress and was always coming up with new ideas to find the right buyer for us. He is thoroughly professional, a great communicator and a genuine nice guy. My wife and I would highly recommend him to any property seller.

Absolutely amazing. The most honest and hardworking agent you will find. John is easy to work with, friendly, approachable, professional and knows the market extremely well. He went above and beyond to make the process worry free and achieve optimum result. John took great care and put everything into achieving maximum result. I had the bar set extremely high and he exceeded expectations. Thank you all so much, can't thank you enough for everything and all the extra work and support you gave and are still giving months later.
