Sold in 7 days, sight unseenFrom our initial conversation with Tanja, we had full confidence in her ability to achieve WELL-BEYOND our desired result. There was zero hesitation or doubt appointing her as our agent. She was honest and had so much confidence in pricing the house and she wasn't wrong. Our first offer was well beyond what we expected and she called weeks before she even saw the finished product of our renovation. We were so impressed with her ability to adapt to the lockdown and still make the sale work for us. We sold our Chelsea Heights home after just 7 days and one virtual tour via zoom. We achieved a fantastic result. Prior to this, Tanja also helped us secure our next property, the dream home. All dealings have been highly professional but with a human touch and we truly appreciate that!Thank you again Tanja!
