Dear Jonathon and Donna,

Once again many thanks and please find below a reference that we hope will assist you in the success of De Brennan Property.

To whom it may concern,

We would like to highly recommend the exceptional service we received from De Brennan Property on the sale of our home. We have sold many homes in the past 25 years but the service we received from Jonathon and Donna was at a level far superior than any other real estate we have experienced.

Presentation, punctuality and knowledge of the market were excellent. Greeting the buyers was always at a professional level and follow up of the buyers and informing us was always completed to the highest standards.

Jonathon would return calls promptly and when exchange and settlement occurred they were handled efficiently.

It was an absolute pleasure to work with De Brennan Property and I have no hesitations in recommending them to any future seller.

Kind Regards

Bernadette and Rodney Furlong (Vendors of 16/1-5 Mandolong Road, Mosman)

I am writing to express my thanks to De Brennan Property for the excellent result they achieved on the recent sale of my brand new home in Northbridge.

Jonathon De Brennan has previously sold and leased other properties for me. He once again exceeded my expectations with the outstanding price he achieved for my Northbridge house.

He and his sales associate Donna are highly professional and worked together with their team, to ensure that every detail was performed to the highest calibre.

De Brennan Property’s trademark professionalism and energy meant that all aspects were carefully considered and the sale was enjoyable and seamless for me.

Jonathon always kept me well informed about all of the buyers and progress on my sale at all hours of the day and night.

I strongly recommend engaging the services of De Brennan Property.

Dear Jonathon and Donna,

Keith and I, decided on De Brennan Property, to sell our house.

With advice from Jonathon and Donna, we had our house ‘made over’.

Jonathon and Donna helped us all the way, it was a great decision, and after 3 weeks of inspections, our house was sold, to almost the first person who had seen it.

We achieved a great price, above the market norm, and couldn’t be happier.

With warm regards,

Jan and Keith Wainwright (Vendors of 10 Cutler Place, Cromer)


Hi Jonathon and Donna

We just wanted to acknowledge the tremendous effort you both put in to sell our family home.

From the moment we met you both and discussed our plans, you worked as a team to ensure that our home was well presented so that we could achieve the best result possible. We are glad we took your advice regarding marketing and minor improvements and the people you recommended to help with these things.

Selling a home is a big decision with many emotional issues to deal with. You both helped us and we are very satisfied with our decision to choose you to support us through this time.

I would be happy to recommend you services, and also your approach, to anyone thinking of selling their property

Thanks again

Pas and Josette Bueti (Vendors of 25 Redan Street, Mosman)
