Will Sarti was solely responsible for the sale of our family home, albeit off market. We are extremely private people and didn't want to advertise or publicly engage with respective buyers or entertain traditional open homes or auctions. We found Will always acted in the most ceremonious manner and we always found he was extremely respectful. Throughout the seamless process Will always would provide support and affirmation which is sometimes needed in the delicate process of selling your family home. The dedication to which he serves people is incredible, and I find him to be a pleasure to talk to, as he is exceptionally insightful. Having always displayed a high degree of integrity, responsibility, and ambition, I have personally been intrigued and impressed with his stance on life.

It was an absolute pleasure dealing with Will from Kollosche, he was extremely helpful in the whole process of selling. He advised in presale and preparation of the property and advised on the right advertising package for the property. Will really excelled in negotiating the right sale price when it came to crunch time and always kept us in the loop with what was happening with buyers and the local market. Will achieved a sale price record for the property and sold the property in a record time on the second inspection. I would highly recommend Will to any prospective seller and would use his services in the future without hesitation. Thanks for a great experience, Ged & Amanda.

Rod and I are elated that our property was sold in just 5 weeks by Matt Lanyon and William Sarti at Kollosche, After 3 months of being on the market already, we decided to change agents as we needed a fresh approach and new energy and that's exactly what we got with Kollosche. Matt and Will's energy transferred to us which we needed and we were able to get to the finish line with their advice and professionalism and their ability to problem solve and negotiate.
