Extremely Professional and Pleasant

Mark was extremely professional and pleasant. He was very easy to deal with and kept us informed throughout the purchase process. A minor issue with the water heater was resolved without any hassles. We would definitely recommend Mark to other prospective buyers.

Excellent Communicator with Brilliant Service!

Seller of a house in Seville Grove, WA Guy was incredibly professional and provided excellent communication through the whole process of selling my house. Due to market conditions, it took a little longer than I hoped to sell but Guy was always patient, confident and provided great advice. In the end he sold the property a lot higher than I expected. Extremely happy with the end result, Thanks Guy!

Entire Experience Exceeded our Expectations!

Entire Experience Exceeded our Expectations!

We recently sold our home through O’Neill Real Estate, and the entire experience exceeded our expectations. From the outset, Mark and his team demonstrated professionalism, experience, and a clear understanding of the market. They made the entire process stress-free by handling everything with calm efficiency and by thoughtfully managing communication — keeping us informed without overwhelming us with unnecessary updates. Mark and his team provided valuable advice on preparing our home for sale, guiding us on what improvements would add the most value. He also created a group chat, which made it easy to ask questions and receive prompt, helpful responses from the team. We had a specific price in mind, and Mark worked diligently behind the scenes to achieve it — ultimately securing a result above what we were hoping for. Throughout, he remained approachable, friendly, and committed to our best interests. After the sale, we were touched to receive a beautiful keepsake book featuring our home, along with a partial refund on advertising costs. This thoughtful gesture really highlighted the care and integrity of the team at O’Neill. We are truly grateful we chose to work with Mark and his team and wouldn’t hesitate to recommend O’Neil Real Estate to anyone looking to sell their home with confidence and peace of mind.

Effective Sales Strategy and Well-supported Team!

Mark had good market knowledge and an effective sales strategy. He is well-supported by his team around him, and Vanessa was a gun project manager who coordinated everything for me including key handover, maintenance, staging, etc.

Excellent agent highly recommend.

Excellent agent highly recommend.

I have known Mark for many years- since high school! We hadn’t been in touch for years but I knew of his excellent professional reputation and knew him to be a genuine, trustworthy guy. So when it came to choosing an agent to sell my house, it was an easy choice! It’s a challenging market for buyers but I feel Marks down to earth approach and sense of humor help to reduce the stress of buying and selling. He’s an excellent communicator. Highly recommend Mark and the O’Neil Team.

Mark is a fantastic agent and I was very impressed by his professionalism and effort. As a buyer, I felt that he genuinely wanted to see me find a home while honouring the goals of his clients. He was knowledgeable and honest. I already know if I am ever to sell my property Mark Grogan would be my choice as a sales agent!
