Stephan Siegfried

One Agency, were highly recommended to us by two people who had sold their homes with Stephan. So we chose them and are sooooooo happy we did. Honestly, you read positive reviews and sometimes roll your eyes, but with this agency they break the mould of any realtor I have dealt with in my lifetime. We were dealing with our father passing, and me having health issues throughout having to prepare the house and get it on the market, but it was made a lot easier when we went to One Agency. Stephan and Jo were always available to offer support, advice, and help us above and beyond what you would expect from a normal real estate agent. Stephan and Jo both have a way about them that is honest, supportive, experienced and respectful. They represented our values, and are...

Karen Dair is the real deal. The elusive unicorn property manager who not only does what she says she will, her actions and treatment of all those she interacts with reflects her values making her a high value person worthy of trust. Friendly, engaging and caring with genuine warmth are words I would use to describe Karen Dair. In the short time of my new tenancy I have found Karen to care for her tenants (I say her’s because Karen treats you like one of the family from the get go) just as much as her owners. A true unicorn property manager indeed. Repairs are actioned promptly with quality contractors. The property I moved into recently was well maintained and clean - a total renter’s dream to move into. It is not just me I have seen Karen treat with...

Selling my home after 13 years was a big and emotional step. Stephan and Jo went over and beyond to help me throughout the entire process. Their communication was excellent, keeping me informed every step of the way and making me feel supported and confident. Their honesty, loyalty, professionalism, and dedication helped me achieve a great result. I truly appreciate all their hard work and highly recommend them to anyone selling their home. ????✨????

Just recently we had the pleasure of dealing with both Jo and Stephan from Agency One. Whey were so professional and helped us get a fantastic sale result on our home. Nothing was a problem and in fact they met our expectations 100%. Great people to deal with. I would recommend Stephan and the team to anyone wanting to sell or buy just like we did. Thanks again. Really appreciate everything you did. Grant and James.

Grant Iceton, 29 May 2026

Stephen was great to deal with and achieve a fantastic result in selling my property. I would definitely deal with Stephen again in the future and would recommend him to others.

Ralph Olbertz, 11 May 2026

Being a trusted and experienced Buyers Advocate & Vendor Advocate it was a no brainer to me when my Vendor Advocate client desired to sell their property in Scarborough. After dealing with Stephan Seigfried and his team on a number of occasions over the years I invited him to represent my client in the sales process. The eventual outcome achieved a significant dollar value over Stephans proposed value, so well done TEAM. I would have no hesitation in appointing Stephan to represent me again.

Stephan McGee, 07 May 2026

We recently had the pleasure of meeting both Stephan and Jo when purchasing a home in Woody Point. They were both warm, professional, personable, responsive without being pushy and quite simply fantastic to deal with. We knew we were in good hands as both Stephen and Jo had excellent knowledge of the local market and surrounding suburbs. We feel confident in our investment and cannot recommend them highly enough.

Dane Bowden, 01 May 2026

We have used Stephan and Jo a number of times in the past. Stephan is our go-to person for any property related transactions. He knows the market, provides honest price estimates and marketing strategies. He is an excellent negotiator. This property was on the market for one day before we received an offer, above our asking price. We cannot recommend Stephan and Jo highly enough!

Ronelle, 28 Apr 2026

Stephan and Jo did an excellent job of selling my home from suggestions on presentation through the photography as well as the detail for the conveyancing and site plans.

Peter Goodman, 08 Feb 2025

I have just sold my house with One Agency Redcliffe with a fantastic result. Stephan and Jo were awesome from start to finish. From the first meeting with them they gave me a Honest price guide and marketing program. They achieved a quick sale at a record price far in excess of my expectations. Jo helped me with the presentation of the property even bringing around some of her own pot plants!! We had multiple offers after the first open home, and it was a very smooth process to settlement. I would 100% recommend anyone looking to sell or buy a property to use the Professional services of One Agency Redcliffe

Murray, 15 Oct 2024

Great Advice! Stephan understood our plans/intension! I have known Stephan since 2015, when we bought this house, we just sold from him. I have stayed in touch with him, as he has with me over the past nine (9) years, chatting about the property market, seeking his advice and our long-term plans with this home (Rental SMSF Investment Property). So, when it was time to act, I reached out to Stephan to sell this property. Again, his advice and sale strategy/timing were impeccable. Stephan made it work, liaising heavily with the tenants, the buyer and us. I highly endorse & recommend Stephan and One Agency Redcliffe to both buy and sell your property.

Colin W, 14 Oct 2024

Handled our divorce sale with ease!! After a long time trying to sort out property settlement with my ex-husband and the stress that come along with that, I can honestly say that it was a true comfort having Stephan and Jo looking after the sale of my property. They both looked after myself and my ex separately during the sales process giving us full updates on open homes, sales inquiries and sales offers. Stephan and Jo sold our place at a street record sales price which blew my mind. During the sales process I found them both to be supportive, honest and have the highest integrity. I would truly recommend these guys to sell your property as they work together as amazing team. Amethyst Court, Caboolture, QLD, 4510

Karen N, 01 Oct 2024

Truly a professional outfit, this team is leaps and bounds above everyone else. You get honest and reliable advice which i find rare in the Real Estate industry. I’m happy I went with One Agency and would not hesitate to recommend them to others. Great work very happy seller!

Shaun S, 14 Aug 2024

Excellent team to deal with and Stephan has been amazing agent to work with. Highly recommended the whole team. seller of 26 Pine Valley Drive, Joyner

Borris, 03 Jul 2024

Over gut feeling was to go with Jo and Stephan when we listed our house, but we were recommended to go with the largest agency on the Peninsula. That was money out the window, as we say it from our part of the world. After a range of low-ball offers, we decided to reevaluate our decision and second time around we followed our gut feeling. OOOH Boy what a difference. Suddenly we were listened to, taken seriously and felt we had a team on our side. Not just any team on our side but the peninsula's best team. From our first meeting all the way to handing over the keys, we felt supported, looked after and valued. Gone were all the arguments between us, gone were the uncertainty and price drop discussion, suddenly we had a team that worked with...

Soren Rasmussen, 01 Dec 2023

What can I say other than Stephan, Jo and the whole team became like family to me with the huge decision to sell my home in Newport. They were so supportive and understood exactly what I was going through and managed to deal with my demands anxieties and everything in between that I was going through. Having rented from them and bought and sold with them I would not go anywhere else. Ty guys for everything you have done for me I so appreciate it :-)

Karren Bull, 30 Oct 2023

Stephan and Jo have an excellent knowledge of the local market. They are honest and provided us with honest advice and feedback throughout the whole selling process. Results speak for themselves!

Christiaan Hattingh, 28 Jul 2023

Selling our home through Stephan Siegfried, Principle of One Agency, Redcliffe was an excellent experience. Stephan was thoroughly professional, kept us constantly in the loop, was not at all pushy and did not once suggest that we lower our price to force a sale - which we appreciated. We achieved our asking price. Stephan's attention to detail and suggestions in preparation and presentation of the house to potential buyers was impeccable and we have no hesitation in recommending him to any person wanting to sell their home. Ray and Margaret Prince

Ray & Margaret Prince, 10 Jul 2023

Stephan and Jo were professional throughout the whole process of selling our home. Both very knowledgeable with the market and kept us informed every step of the way.

Lewis Wells, 01 Feb 2023

Jo and Stephan are the best! I would not be where I am without them. Their guidance to both myself and the buyer was invaluable for an outstanding outcome. Their support with the big things to the smallest, their linkages to the community, their vast experience and professionalism made this very easy at a time I was swamped. I would recommend no one else and it will be my pleasure to do business with either of them again. They are an excellent team that understand the market and the individual - whatever their role may be. Take my advice because theirs is beyond a mere transaction - it’s priceless. Thank you both so much. Kirsten

Kristen H, 05 Dec 2022

We recently sold our home through One Agency - Redcliffe and couldn’t be any happier with the service provided by Stephan and Jo. They were both professional, open, honest and very easy to deal with at all times. Their reassurance of achieving our asking price kept us motivated throughout. Thank you again Stephan & Jo.

Bruno & Gayle, 03 Oct 2022

I recently purchased a property through One Agency. Stephan was sensational to work with his integrity , openness , kindness , efficiency and professionalism was second to none. Whether you are buying or selling I highly recommend using One Agency

Marilyn Stivens, 16 Sep 2022

Couldn't be happier with Stephan's service. The price he secured for our home was above our expectations. He is very approachable, pragmatic and a pleasure to deal with. Nothing was too much trouble for us - or the buyers. Highly recommend.

Paula & Craig C, 02 Sep 2022

Jo and Stephan were great. I recently purchased from interstate and they were welcoming, supportive and reassuring.

Hayley Lalor, 01 Sep 2022

Seller of a house in Margate, Qld Jo and Stephan just recently sold our family home after many years being in the same family.Their professionalism was outstanding to say the least, as both of them have strong real estate backgrounds. They listened to our queries and concerns as this was very difficult time for our family which made the whole process easier for all of us. Jo and Stephan know the current market and nothing was a problem, in fact, it literally took away any stress out of selling our property.Well done, thank you.

Sonja, 06 Aug 2021

We'd like to thank you Stephan for all you have done for us over the past few months to sell our family home. We have no doubt that had we chosen a different agent we would not have had such a positive experience and achieved such a good price for our home. You were always enthusiastic & professional and we would have no hesitation in recommending your services to friends and family.

Marilyn & Craig, 30 Jul 2021

Stephan from One Agency achieved a smooth and timely sale for us at a price that exceeded our expectations. He was extremely pleasant to deal with and handled a delicate tenant, who could easily have stalled our sale, with a level of tact and respect that facilitated the best outcome possible. I would not hesitate to recommend him to anyone and will seek Stephan's advice and representation in any future real estate transactions. Thank you Stephan!

Rebecca, 28 Jul 2021

‘Stephan and One Agency were recommended to us by both a buyer and a vendor, and we were not disappointed. Stephan demonstrated his passion for real estate and his knowledge of the local market was invaluable. Communication was open and valuable personal feedback was always provided after inspections. Stephan and Jo were both very approachable and professional in achieving the desired result. We would highly recommend Stephan, Jo and One Agency.’

Sue & Richard, 20 Jul 2021

I've used One Agency to sell my property twice, each time I have had Jo Fenton as my agent. She did a wonderful job and was super patient and got the best price for my property. All the staff at One Agency are friendly, courteous and professional. I would definitely sell with Jo and the team at One Agency again.

Terry, 15 Feb 2021

Exceptional local knowledge and positioned our property accordingly. Always communicated at a high level and delivered it in a personalized way. Wish there were more agents at the same caliber as Stephan.

Helen, 09 Feb 2021

I found Stephan to be very approachable and knowledgeable about sales and buyers in his local area. He demonstrates a passion for realestate and really knows his market well. He willingly provided great advice on what would be best to market the property and followed up frequently as worked progressed on the house. Stephan provided thorough data on recent sales, market trends and buyer wants which helped us achieve a better than expected outcome in the sale price.

Patricia, 07 Feb 2021

We have dealt with plenty of agents over the years and never trusted any as much as we have Stephan. He is honest, efficient and professional and for these reasons we had a lovely selling experience.

Taylah, 12 Jan 2021

I engaged Stephan & Jo from One Agency Redcliffe to sell my investment property at Scarborough. Prior to listing I had spoken with a number of different agencies but was very impressed with the advice Stephan provided concerning the value of the property and the reasons for that and the strategy for selling the property to achieve its maximum value. Stephan and Jo were professional and approachable and kept me well updated through the process. Most importantly they achieved the desired result.

Shane, 15 Dec 2020

Lives up to his promises and achieved fabulous result for the sale of my property. As a returned client, I would not go anywhere else! Stephan is simply the best.

La, 18 Nov 2020

Stephan was a great agent to deal with. He kept us well informed all through the process.

Danny, 04 Jan 2019

We recently engaged Stephan to sell a property at Newport and were very impressed with his service, communication and client service levels. Stephan is very knowledgeable about the local property market, which, combined with his great communication skills and friendly approach, was the reason we initially chose to engage him. The property was sold in a timely manner, and we would certainly recommend Stephan.

Jessa, 17 Dec 2018

Stephan was great to deal with and is a very communicative operator with extensive experience in our Newport QLD area. Stephan was able to quickly negotiate a sale price that met our requirements at a time when all the news on Real Estate was doom & gloom. We would have no hesitation in recommending Stephan Siegfried and One Agency and infact have already done so. As a further indication Stephan was recommended to us by one of his happy customers.

Kristen Kingsley, 13 Dec 2018

This is the third property I've sold with Stephan in the last 5 years and I couldn't be happier with the results. The service and communication was of the highest level and we were impressed that they even did inspections on Sunday when needed. I trust Stephan and his team, he knows the local area values and has been spot on with all of my house sales so far.

Caroline, 12 Dec 2018

An easy over, pleasant experience from a start to finish..... Worth every one of the 5 Stars ***** We are happy campers. For a pair of fiercely independent people, who like to do everything ourselves, Lloyd and I were anxious about having to leave the sale of our home in the hands of someone else. We had contacted four real estate agents and told each one we were interviewing them for a job – the sale of our little home. We chose OneAgency Redcliffe, and we couldn’t have hoped for a better result. Stephan was a stand out immediately. Based on his research of our area and our property, Stephan explained what his marketing strategy would be. He was right on the mark from day one and as he left our home that first day, we both breathed a sigh...

LloydLynelle, 26 Nov 2018

Professional Agent Attentive, focussed, good knowledge of the market in the target area and is willing to tailor the marketing strategy to the vendors wishes.

Walter & Fay, 26 Nov 2018

Second Sale with Stephan This is the second property I have sold with Stephan at One Agency, Stephan is always professional and fantastic communication. We have met the buyers of our home a number of times since the sale and speak very highly of their experience as well. Well Done!!

Douglas, 29 Oct 2018

Outstanding result! We had been trying to sell our home for a while with another generic real estate office and had been advised to go to auction. The house was passed in and these agents pressed us to accept the highest bidder and that was all the house was worth and then proceeded to pressurize us other the next few weeks to reduce our price. Goodness knows what we were thinking by not using Stephan in the first place but once we changed over to him things really began to change for the better. He and Johanne worked so hard to get the result the home deserved. We were so pleased with the price that he achieved for us as our home was very unique and it needed someone to come along who would love it as we did for...

Elaine Brophy, 25 Oct 2018

Honest Up Front. Dear Stephan and Team. It was a pleasure to use your company for the sale of one of our investment properties. Whilst undertaking the sale you also took the rental on board making it great Synergy for the sales process. At all times we were kept up to date with all activities, wit a down to earth up front honest feedback. Please also to have you and your team listen to our comments and taking them into consideration for a win win situation. To anyone needing an agent in the Redcliffe Peninsula to North Lakes areas, I would have absolutely n hesitation in recommending Stephan and he team. Well done.

Damien & Debbie, 22 Oct 2018

Great agent This is the second time we have used Stephan's services. The first was with a buy and then we used him again for a sale. So we have been on both sides with our dealings and in both instances he made the whole process very easy with great communication along the way. We would recommend Stephan to anyone and would use him again in the future.

Suzy B, 14 May 2018

Exceptional There really is only one word for Stephan and thats exceptional. I have dealt with a lot of agents over my time and this guy stands out- miles above the rest. From honesty to knowledge I could not have asked for more. My only advice ... use this guy!!

Dean & Christine, 01 May 2018

"Simply the Best" My initial research showed that Stephan had the most success in property sales for our area and for this reason we asked him to sell our home. From the time we first met Stephan and Jo, they impressed us with their communication, marketing skills (including a comprehensive buyer database) and importantly their up-to-date knowledge of the property and sales market. The marketing of our property was well planned and resulted in good attendance at our open houses with strong buyer interest. Stephan kept us well informed on a regular basis. We achieved our sale at the price we were seeking in a reasonable time frame. We thoroughly recommend Stephan and the One Agency team, they were excellent.

Brian & Judy Gill, 28 Mar 2018

A pleasure Working with Stephan & Johanne was a pleasure. A great line of communication and information. I can see why people buy and sell with them on multiple occasions/properties.

Sabina & Chris, 27 Mar 2018

Fantastic! It was a pleasure to deal with Stephan. You can expect professional and knowledgeable advice. Communication was important to me and I wasn’t disappointed, I never felt out of the loop. Stephan doesn’t sugar coat the facts and is realistic about your expectations. I wouldn’t hesitate to recommend his services!

Nichol & Mark, 15 Mar 2018

Down to earth honest agent. I had noticed Stephan from one agency selling property in my street and asked him to sell mine. From our first meeting I noticed stephan didn't try to pump my property up and gave me some good advise on how to present my home. I did my part and took his advise and he did his part. He got me top dollar and I have no problem recommending stephan to anyone selling there home.

Paul, 12 Mar 2018

This is the Third property sale Stephen has achieved for me Stephen and his fantastic team at One agency, did a terrific job of selling my home, from the moment I called him he was on the job, creating a great video, and perfect photos and house brief, we ran 7 open houses and the house was sold, its not any one thing that is a stand out - Stephen is the complete package he leaves nothing to chance. I am writing this as some people may choose an agent to sell your largest assets based on price but I urge you to speak with Stephen, he is the real deal, I have no hesitation in recommending him and his team to get your house sold, a saying that I have always believed in "if you pay peanuts you get...

Lana Vella, 04 Mar 2018

Fabulous experience! Stephan and Johanne provided us with a quick and stress-free selling experience. Based on their expertise having purchased our home with them, we then hired them to sell our home. We couldn’t be happier with the price, communication and time it took to sell our home (1 day!!). I believe the preparation and client base this company provided is what resulted in such success. These are seriously great people, and I highly recommend them!

Amy & Matt, 08 Feb 2018

Efficient agent We found Stephen to be a very efficient agent with great knowledge of the area. He obtained the best price for us, of our last two properties. He managed to obtain a very good price and valued our properties not just on historical sales in the area but on the true value of the property. We would recommend him as an agent to anyone.

Gary & Mirian, 03 Feb 2018

Great agent We recommend Stephan 100%. We appreciate his eye for detail, marketing approach and his perspective on the value of the property. He did what he said he would do, plus much more.

Cassi & Chris, 02 Feb 2018

Excellent agent Having bought and sold 15+ properties over the years, we can categorically say Stephan is the best agent we've had the pleasure of dealing with. Very knowledgable and above all else, honest. I highly recommend Stephan to anyone considering selling or buying property. Mike & Carole Cox

Mike & Carole Cox, 01 Feb 2018
