Integrity, ethics & extraordinary negotiations skills!

Integrity, ethics & extraordinary negotiations skills!

Greg Costello a long time friend was engaged to market and sell my home in Beaumaris not simply because of his unquestionable reputation but also because importantly, his integrity and ethics and extraordinary negotiations skills. We were confronted with a rapidly changing market late 2024 and despite this, Greg didn’t wilt, remained positive and importantly was very open with me to explain all possibilities. Nothing but praise for Greg and testimony to that, he still remains one of my great friends. A great outcome!

Above and Beyond, A Superb Realtor

Greg is a superb realtor - not only does he know the market but goes the extra mile ! He helped with literally everything from going to the bank to buying flowers. Available until late at night 7 days a week ! Flexible, compassionate, helpful at all times. I couldn’t imagine anyone else who would have done the same. He obtained a great price. He is a beacon in his profession. I would recommend him 100% ! He has the patience of a saint and zero defaults THANK YOU !!!!

Genuine, enthusiastic, diligent and thorough.

Greg was fantastic from the moment we engaged him. His endeavour, determination and expert knowledge regarding the special nature of selling our property was second to none. He was always on the front foot and positive and clearly communicated what the market was saying. We highly recommend Greg to sell your property. He was superb and we are very happy.

Excellent Service and Knowledge

Throughout the entire marketing campaign and sale at auction (as planned), Greg's insight, communication, market analysis and auction performance could not be faulted. I had used Greg previously and had recommended Greg to a close friend of mine. All sales were completed very successfully. I would have no hesitation in recommending Greg to others and would look to engage Greg again for any other real estate marketing and sales campaigns in the future.

Great result despite selling in a challenging time

Greg did an excellent job selling our place in the lead up to Christmas and whilst dealing with a challenging market during Covid 19. He talked us through the entire process, strategy and campaign and kept us informed at all stages. Very happy with the result. Would happily recommend.

Excellent and honest

From my first meeting with Greg I found him to be very professional. He has so many years in the Real Estate Industry and a great knowledge of the area. Most of all he cares about his clients moving forward, always going above and beyond to help. During COVID in the hardest of times he worked so tirelessly clinching the deal for us both with great communication, honesty and consistency. For these reasons I would definitely refer Greg to anyone thinking of selling or buying.
