Lovely team to work with

Lovely team to work with

We hadn't considered the property we ended up buying but Sinéad encouraged us to have a look. It ended up being perfect for us and we can't wait to roll our sleeves up and make it our own. The team were all brilliant, and we were able to arrange a few extra viewings with no trouble. We would definitely recommend Team Sinéad to anyone looking to buy or sell.

Professional and knowledgeable throughout the buying process

Professional and knowledgeable throughout the buying process

Sinead and the team did a great job across the board from showing us the house early on and through the open homes. Information was provided in a timely way and we felt fully informed throughout. There was really good support through the auction process from dealing with special conditions, a pre-auction session which was really useful, and support on auction day. Follow up service has also been great, with all queries answered quickly and professionally. Thanks to Sinead, Jen, Elsa and Nick who all helped along the way. Great job.

Thank you Team Sinead

Sinead and her team were professional, knowledgeable and energetic in their marketing of my property. They were approachable, super-helpful, and responsive whenever I had queries, kept me updated with progress, and know the local market well. I highly recommend Team Sinead.

Great Team & Top Service!

Great Team & Top Service!

A big thank you to Team Sinéad and Jen Schipper at Harcourts for helping us secure 66 Copeland Street. The entire team was super friendly, quick to respond, and made the purchasing process straightforward and transparent from start to finish. Fantastic service all around! After our initial offer didn't go through due to price and conditions, Jen helped us navigate the deadline process to successfully secure the property. Her support didn't stop there—she stayed in touch continuously after the offer was accepted to ensure everything was going right for us. Thank you, Jen and team, for all your hard work!" Thanks again

Approachable, proactive, and warm

Team Sinead were unwaveringly friendly and responsive; they made a genuine effort to help us navigate the challenges that come with entering the housing market for the first time. Each member of the team was approachable and fast in actioning anything we needed to know. We could tell they make a great team. Thank you.
