Principal Property Director and Principal Real Estate Agent at Principal Property Real Estate

About Siobhan Cowell

I'm Siobhan Cowell, Director of Principal Property and a licensed real estate agent with 12 years of experience selling homes across Brisbane’s northside. I’ve built my business on straightforward advice, clear communication, and a strong understanding of the local market.

Before real estate, I worked as a Registered Nurse and later as a Pharmaceutical Sales Manager in London. That background taught me how to deal with people in high-pressure situations, stay organised, and communicate clearly—all skills that still serve me well in real estate.

Over the years, I’ve bought, sold, renovated, built, and subdivided property myself, so I understand the process from both sides. I don’t give textbook advice—I draw from hands-on experience and a solid track record in sales.

I work with a small, experienced team and we focus on doing the job properly. I don't overpromise. I give clients a realistic picture of the market, what their property is worth, and what’s possible in the current conditions. I’m not interested in hype—just in delivering a good result with as little stress as possible.

Most of my business comes from repeat clients and referrals, which says a lot about how I work. I’m reliable, direct, and focused on the outcome. If you're selling or leasing on the northside, I can give you straight answers and useful advice to help you move forward.

Testimonials

Siobhan is amazing, very professional, a great communicator and also very sensitive to the issues for a family in relation to selling a home. We felt completely safe with Siobhan, she provided excellent guidance throughout the whole process and made a difficult decision to sell our beautiful family home so much easier. We are very happy and grateful with the outcome and would not hesitate to recommend Siobhan or use her services again for the sale or purchase of property.

Siobhan provided invaluable assistance with the recent sale of my house. She displayed good awareness of the local market and kept me updated throughout the process. Siobhan is a proficient negotiator who clearly puts the interests of her client first. I was very happy with the result and would recommend her anytime.

Siobhan was amazing, she was organised and did what she said she would do. Very helpful with advice and made the whole process seamless and easy for me. She is always welcoming and friendly and had both buyer and seller's interest in mind, being a very reasonable and professional negotiator. I would definitely use her again.

As a first home buyer I kept missing out by the smallest of margins. After contacting Siobhan, she not only provided me with great tips and tricks to get into the market, she looked over properties that I wanted to make serious offers on and gave me great advice on how to make the best offer. She always made herself available and although I found a property under a different agent she continues to check in and assist where needed. With her guidance I was able to obtain a property. Finance broker and Solicitor, by her recommendation, has made the whole process so much easier and I am confident with my new purchase. I highly recommend her and have already told my friends looking to get into the market to reach out.
Siobhan I can't thank you enough for everything.

Siobhan completely understands the market and responds in a timely manner. She is a true professional and as a bonus honest and forthright. She helped us understand the process but allowed us to come to our own conclusions. Her commitment to communication and ability to listen and understand our needs fostered a mutual trust.
We can’t thank her enough for helping us find our home in a community we thought we were out-priced for.
