Testimonials

  • Mark is very professional and friendly. Superb agent!

    Lennon & Ma

  • We found Mark to go above and beyond our expectations when it came to selling the house. Mark was extremely helpful in achieving a positive outcome for both parties. His attention to detail ensured the sale of the house went through smoothly. We would highly recommend him to colleagues and would definitely use his services again in the future.

    Marcus & Carolyn

  • Willing to relay all offers and a savvy negotiator for a higher sale price. If I was a seller I'd be happy with the work he put in. Easy to work with as a buyer, open communication and fast response time.

    Edward

  • I cannot begin to describe how impressed we were with Mark. From our first meeting he was professional, listened to us and offered sound advice. Mark took the extra time to do thorough research of the current market on our behalf prior to listing our property to ensure we listed it at a competitive price that still met our needs. The attributes that really stood out to me with Mark included: - His outstanding communication skills- he ALWAYS listened to our wants/needs and consistently gave us feedback and kept us informed about how the sale was going. -His dedication and passion about real estate, this isn’t just a job for him- he lives, breathes and LOVES it! -His professionalism, Mark was always well presented and ready to work. -Above all, Mark is genuine, he gave us honest and realistic expections. If you are looking to sell in the Toowoomba Region then it’s most definitely worth contacting Mark, once you’ve met him you’ll know he’s the agent you need!

    Andrea & Jeremy

  • Mark was most professional throughout my recent purchase. He responded to my queries in a very timely manner and was most obliging during the negotiation and purchase process.

    Cathy

  • We couldn't be happier with the result of sale of our Rangeville property. Mark was able to source several buyers prior to advertising or marketing the property at all. His enthusiasm to get us the best price was overwhelming, he continued to work with his buyers to get the price we were looking for. His genuine nature in wanting to save us money and time was refreshing. We would thoroughly recommend Mark (and already have) to anyone looking to sell or buy in the area. Thanks again Mark!

    Janelle

  • I found Mark very easy to deal with, I was extremely happy with Mark's communication & negotiating skills, he kept me updated through out the entire process. Our house sold after only 2 weeks on the market. I would highly recommend Mark as an Agent!
