Experience the SHELMARK difference

Local residents since 1990 and owners of boutique real estate agency, SHELMARK since 2006, Shelley and Mark Clayton work in tandem to help their clients achieve their property goals.

As business owners, licensed real estate agents and residential sales specialists, Shelley and Mark are 100% committed to their clients and the business they have built from the ground up. The husband and wife team are known within the community as the hardest working, most honest, down-to-earth and results-focused real estate professionals south of the river. It’s no coincidence that most of their business is referred and repeat.

Bestowed multiple real estate awards over the years, Shelley and Mark's focus has never been on the accolades. Rather, their mission is to provide an unsurpassed real estate experience to every client they work with. Many have engaged them multiple times to transact property on their behalf, some becoming good friends in the process, a testament to the level of trust earned over time.

“There’s a lot more to selling a property than most people realise. We take the stress and hard work out of the process for you and our negotiation skills can make a huge positive difference to the price achieved. We also provide additional services to you such as property preparation, styling and professional marketing – all aimed at improving your chances of a successful outcome and making the entire process a smooth and rewarding one.” Shelley Clayton
