Property Sale

We were very happy with the level of service provided by Mark. We found him to be very thorough, very experienced and very reliable. He communicated with us constantly throughout the process and worked hard to find the right buyer for our property. We would happily recommend him to anyone wanting to sell their property around our area.

Excellent communication skills and a good listener.

Excellent communication skills and a good listener.

We had several real estate agents come and review our property and we went with Mark because he actually listened. We had expectations about how we would like our home marketed and he realised our vision. Ultimately we liked his down to earth approach which is solidly backed with a comprehensive knowledge of the market and a feel for when the buyer was genuine. He didn't waste our time with "fluffy" feedback but rather gave us realistic ongoing appraisal of potential buyers and price expectations. We couldn't be happier and would highly recommend his service.

An A-Class Agent who provides professional services with a personal touch

An A-Class Agent who provides professional services with a personal touch

Mark stands out as a highly impressive property agent that I have ever met in my property transactions. Given his remarkable duration of service in the Lower Northshore communities and outstanding career achievements, he seems to be known and recognised by most of the visitors who come to inspect the property. Being a nice gentleman with extensive knowledge and experience in his professional area, Mark also approaches his clients with respect and patience. I believe his professional manners and etiquette assigns additional values to the properties he is engaged to look after. I would like to thank Mark wholeheartedly for a fantastic transaction experience!

Timely communication and strong depth of experience in the sale process

Mark is well-known as a trustworthy and highly knowledgeable agent in the lower North Shore. His management of the sale process of our waterfront property in Northbridge was top-notch, and he provided timely feedback after every open house. We had a great experience working with Mark, and highly recommend him

A quick result with minimum of fuss

A quick result with minimum of fuss

We asked Mark to present his strategy for the sale of our house taking account our desire for minimum fuss. He made us feel very confident that he could achieve our objective and we felt very relaxed in putting our trust in him. His extensive knowledge of the market enabled him to assess a likely sale price the accuracy of which was borne out by the sale which we achieved within 3 days of being open for inspection. This result exceeded our expectations by far.

Mark brings all of his many years of experience, skills and knowledge to achieve great results.

Mark has unrivalled knowledge of the area and almost 30 years of experience in "the Crag". Mark is a skilful, knowledgeable and experienced agent, with an engaging personality, who used those qualities to achieve a good sale price in challenging and unexpected market circumstances in March 2020. Mark kept me up-to-date during the marketing period and answered all my questions. Mark also has a skilled team of ancillary service providers for the preparation of marketing material.

Straightforward & stress free.

We just purchased a property from Mark in Castlecrag. We live overseas which had its challenges but Mark was very strong at communicating and accommodating us. Mark was prompt and straightforward in his approach, providing us with what we needed to make informed decisions. Given how stressful these things can be, it was an incredibly smooth process - hopefully for the Vendor as well. Overall, I'd highly recommend Mark.

Property sale by Mark O'Brien (Richardson & Wrench Castlecrag)

Mark has demonstrated his extensive knowledge and experience in castlecrag properties. From the moment he was engaged to sell the property, he took leadership in organising the services required to prepare and present the property at its best. Mark has kept us informed at all times and managed the whole process with professionalism, integrity and achieved a good outcome. I have dealt with Mark in the past and would use and recommend his services in the future.
