We had a signed contract within 3 weeks with Mark Deegan as our Agent

Mark was absolutely incredible from our very first meeting right through to signing the contract and beyond. His professionalism, communication, knowledge and dedication made the entire process smooth and stress-free. We felt supported every step of the way and always knew we were in great hands. Mark went above and beyond to make sure everything ran seamlessly, and we couldn’t have asked for a better experience. We are so grateful for all of his hard work and would highly recommend Deegan and Co to anyone looking to buy or sell a property!

Listed Tuesday, Under Contract Saturday – Outstanding Communication Every Step of the Way
5 months ago
Listed Tuesday, Under Contract Saturday – Outstanding Communication Every Step of the Way

We recently sold our property through Mark from Deegan & Co, and the entire experience exceeded our expectations. We listed the property on a Tuesday, held the first open home on Saturday, and by Saturday night Mark had secured a signed contract. The sale then went unconditional the following Friday. The speed of the result was impressive, despite challenging market conditions, but what stood out even more was the professionalism and communication throughout the process. Our property had tenants in place under a somewhat complex leasing arrangement, which could easily have made the sale difficult. Mark handled the situation exceptionally well, building a positive relationship with the tenants and managing the process so effectively that we were able to remain largely hands-off. He kept everyone informed, ensured inspections and negotiations ran smoothly, and achieved a great outcome without creating unnecessary stress for any party. Communication was excellent from start to finish. Mark provided timely updates, kept us informed of every development, and was always straightforward and honest. There was no sales spin, no fluff, and no surprises, just clear advice, regular communication, and a genuine focus on getting the best result. Thank you Mark from Deegan and Co!!
