Boutique Realty provided exceptional service, Mathew St Guillaume achieved an amazing sale price.

Mathew is genuine, friendly, and very easy to deal with, he and his 5 star team provided a truly professional service. Mathew recommended pre-sale refurbishing works, and staging to ensure my home was beautifully presented to attract multiple buyers. The seamless sale process was executed with diligence, speed, and a strong commitment to achieve the best sale price possible. Mathew delivered an incredible sale price that was significantly in excess of my expectations. I would highly recommend engaging Mathew, he is a delight to deal with.

Mathew has an excellent knowledge of real estate in the Floreat area and located a property perfectly suited to my daughters needs. I would not have considered the property that we purchased unless Mathew had arranged a viewing for us. Mathew and his team were all extremely helpful and professional throughout the purchasing process.

Outstanding Agent with an Exceptional Team..

Working with Boutique Realty Perth was exceptional. The team operated with precision, speed, and clear strategy from day one. My property went from first contact with Mathew to listing within a week and an accepted offer in 10 days. Communication was consistent and professional throughout. Mathew was calm, knowledgeable, and decisive, making the process effortless. The team delivered outstanding marketing and a seamless, results-driven experience I confidently recommend.

Seamless Process & Record Price

Seamless Process & Record Price

An exceptional experience from start to finish. The entire process was handled with a high level of professionalism, discretion and expertise. The strategy behind the off market approach clearly paid off, delivering a fantastic result that was a record price in our area, without the stress of a full public campaign. Couldn’t be happier with how smoothly it all came together. Highly recommend to anyone considering selling. I understand completely why Mathew is number one selling agent in his area. Five stars all the way.
