Gretta and her team are very professional, and I can only say that she produces results immediately. She is very hard working and has your best interests at heart always. I recommend Sapphire Realty as an excellent agency to either list or buy.

Seller of Duplex/Semi-detached in Avoca, Qld

Gretta was an absolute pleasure to work with on the sale of our property. She was very professional and kept us updated on the progress each step of the way. Her constant communication and personal approach made the experience quiet enjoyable and stress free.

Seller of Acreage in Gooburrum, Qld

Monica was very approachable and easy to deal with. She went out of her way to assist in any way possible to get the property sold. She responded quickly to any requests for information. The property was listed and shown quite quickly which then led to a speedy and successful result.

Seller of House in Norville, Qld

Monica was so helpful, she was very friendly and went out of her way to make it as less stressful as she could. She came, looked at our property and gave us a good figure to put on the market. Our property only lasted 2 weeks and got well above the asking price. Will definitely use her again.
