A perfect campaign!

We could not have asked for a better experience selling our house. From the very initial conversation the attention to detail and quality of the advice ensured we were at ease throughout. Working with Gianna we really felt we were putting our best foot forward going into the market, confident with the campaign and with how we had prepared the house. We ended up selling prior to auction within a week, well beyond our expectations. The support from other staff we dealt with at the OC agency through the process was also really professional and friendly.

Genuine professional

We recently had the pleasure to buy a property through Gianna. Gianna is a genuine professional, who understands this process can be overwhelming. Gianna represented the seller perfectly, all while supporting the purchasers. There was no query that was too difficult for her to assist with, especially after-sale service. Gianna had an excellent knowledge of the local area, which shows her experience and in particular local knowledge. I would recommend Gianna to anyone looking to sell or buy.

Gianna was amazing

Gianna was amazing, very responsive and accomodating - she always made time for us taking into account we both work full-time and a young family. Her customer service was exceptional and would highly recommend her to others looking to buy or sell! Well done and thank you for making our selling experience a great one!

Consistent, clear, concise & thorough

We met Gianna 4+ years ago when we bought a property which she was the selling agent. We recently utilised Gianna's services to sell a property. On both occasions we have found Gianna consistent, clear, concise and thorough from both sides of the fence. Gianna has a sincere ability to be personable and professional at the same time, thank you!

Top agent!

From the first meeting it was clear to my wife and I that Gianna was the right agent for us. She was friendly and knowledgeable, and honest about the value of our property and how to prepare and present it for sale. Thanks to Gianna, negotiations with the buyers proceeded without fuss. We felt confident when we signed the sale's contract that Gianna had achieved the best result for us.

Highly recommended

I wouldn't hesitate to work with Gianna again or to recommend her to others. Friendly and knowledgable with excellent communication, Gianna guided us with all the information we needed and kept us up to date along the way.
