"Cornelia recently helped us sell a property, and working with her was a real pleasure! She brings the kind of calm professionalism that we appreciate, and her advice was thoughtful and spot-on. We felt very well supported at every step of the process. Cornelia's experience shines through in the important moments (e.g., during advertising and negotiations), and she is more engaged than any other realtor that we have worked with. Plus, she finds an excellent balance in her communication, so her engagement feels welcome and not at all intense. We would definitely work with Cornelia again!"

"It was a great pleasure working with Cornelia to sell my town home. Cornelia is very professional and will go to great lengths to satisfy her clients. Right from the start, she came prepared with a thorough market evaluation so we could set realistic expectations to sell the property quickly and at the best possible price. She took care of all the details and made sure the transaction proceeded smoothly from beginning to end. Cornelia is very organized and had a clear plan and timeline to close the transaction. She kept me informed at every step and promptly returned phone calls or emails. She would go out of her way to get all the information on potential issues so we could make quick decisions. In addition she always kept a backup plan should any unforeseen issues arise. I can highly recommend Cornelia and would hire her again for my real estate needs."

"I wanted to take a moment to thank you for the professionalism and collaboration you brought to this transaction. It was a pleasure working with you, and I truly appreciate your dedication and attention to detail throughout the process."

"Cornelia worked tirelessly setting me up in my first home, and negotiated ruthlessly to her own detriment (lower price means lower commission, something that never deterred her which is deeply admirable). She was incredibly professional, knowledgeable, and an overall pleasure to work with. She double checked every detail and managed complications seemingly effortlessly. I cannot recommend her highly enough."

  -Andrew Bender, Client

"Excellent and honest agent. I would recommend Cornelia to anybody who is looking for a honest and straightforward agent. She’s working in your best interest. We were very happy to do business with her."

  -K.M., Client

"Cornelia helped me almost 10 years ago to purchase an investment townhome in Tucson. I did not hesitate to call her again when I needed to sell it, during a tough year in real estate. Well Cornelia did an amazing job; we got the home sold in 3 days for top price and it closed in 3 weeks. I have referred her several times in the past and she is hard working, dedicated and knowledgeable about Tucson market. Make sure you call her first whether buying or selling."

"Cornelia Nestler helped us to purchase a home a couple of years ago. Because of the great experience and her outstanding work, we chose to work with her again when we had to sell the property due to a job transfer. She gave us excellent advice on what we needed to do to prepare the house for sale to get the highest price possible. She was available around the clock and goes above and beyond of what a typical real estate agent does; making sure that all T’s are crossed, and all I’s are dotted. We trusted her completely and even asked for her advice when we purchased in another state, where she helped us find a local agent and supported us through that purchase as well. Cornelia is very patient and her communication with us was exemplary. We would always choose her again to represent us."

  -K.M., Client

"We met Cornelia, when she helped us buy our dream house. Fast forward 5 years, when we had to sell the house owing to a job-related move, the only person we wanted to work with was Cornelia. Even before we listed the house, Cornelia spent many hours with us trying to nail down the list price. It was a bit difficult to nail down the list price, but Cornelia was patient and brought a number of resources to bear to help us. She was honest with us about any work that we needed to get done on the house as well. All that hard work paid off when we got a list price offer within 24 hrs. The final negotiations turned out to be a bit tricky and Cornelia expertly navigated the minefield - all the while being very responsive and detail oriented. If you are looking for a talented, diligent, responsive, honest Real Estate agent and a skilled negotiator, look no further than Cornelia Nestler."

  -D.K., Client

"Cornelia is the best! She helped my wife and I sell our home and purchase another one in Tucson in March of 2025. Her attention to detail, professional communication, and local knowledge helped us navigate an unpredictable housing market. She went above and beyond in every situation and we always felt like that she had our best interests in mind. One example was that she discovered that the home we lived in (and were selling) had been misclassified on our property taxes. She let us know how to contact the county and we ended up getting a sizable refund. We would absolutely recommend Cornelia to anyone in Tucson looking for a class-act realtor!"

  -K.L., Client

"It is our pleasure to recommend Cornelia Nestler for anyone that is looking to buy or sell their home. Cornelia helped us buy our dream house and helped us sell that same house, 5 years later, when we had to relocate due to work. When we started looking for a house 5 years ago, we did not know what we wanted. Cornelia was patient with us and worked with us to help us articulate what it is we were looking for. Her attitude was “Let us figure out what you are looking for, together” as opposed to, “Tell me what you want and I will show you the listings”. That really helped us find our gem of a house. The house was a short sale and needed some finesse during negotiations and Cornelia was up to the challenge. Cornelia’s honest opinions re: value of the house and the work that will be needed really helped us finally get the house at a price point that we were very comfortable with."

"As a Real Estate Investor working with a skilled agent is crucial for the success of my business. I have worked with Cornelia Nestler repeatedly over the past decade and despite having been approached by many other agents always decide to work with her on sales and purchases. Cornelia is a skilled negotiator and has secured properties often at a significant discount to comparable objects. Cornelia is always available and responsive. She will diligently coordinate and attend inspections and guide through the process of requesting adjustments to the contract, be it repairs to be done by the seller or credits for disapproved items. Through the years of working together, we also completed some more complex transactions such as a seller carry-back and a 1031 Exchange. Cornelia was always on top of the situation and had the experts available to advise and support in these proceedings. I am looking forward to my next transactions with Cornelia and can recommend her without hesitation."

"I cannot overstate how efficient and knowledgeable Cornelia is. She was invaluable throughout the process of buying a house, and even continued helping us after closing with all our first-time-homeowner questions."

  -M. M. , Client

"Cornelia Nestler was a fabulous Tucson real estate agent to work with. In fact, I have already recommended her to others, including my daughter who was a first-time buyer. Cornelia is incredibly knowledgeable, patient, extremely detail-oriented and very helpful. She made the whole process seamless and efficient. I will definitely use her in the future if the need arises."

  -S.B, Client

"I had the pleasure of working with Cornelia Nestler as my buyer's agent, and I must say, the experience was nothing short of outstanding. From our initial conversation to the closing of the sale, Cornelia demonstrated unparalleled professionalism, dedication, and expertise. She paid the utmost attention to my desires and needs. Throughout the process, Cornelia was proactive in keeping me informed and involved. She promptly responded to my inquiries, no matter the time of day, and ensured that the seller’s side fulfilled their obligations. Cornelia’s transparent communication helped me feel confident every step of the way. Her expertise in navigating the complexities of real estate transactions was evident in her ability to secure favorable terms during negotiations and throughout the process. She proactively stayed on top of things and ensured that repairs were performed and documented. If you're in search of a buyer's agent who will go above and beyond, look no further than Cornelia."

  -Tina B., Client

"Cornelia Nestler was attentive, thoughtful, and has a fantastic efficiency and precision (as Germans are known for) that one could wish for in a realtor. She definitely went the extra mile that you would hope for from your agent, so you can get your property sale optimized. I hope to do business with her again one day."

  -R.K.H., Client

"I just wanted to say THANK YOU for connecting us with Cornelia Nestler as our agent in Tucson! She has gone above and beyond what anyone could expect from a Realtor, especially considering we decided to rent instead of buy. Cornelia has helped us through the entire lease process and contract negotiations. For someone who will not be getting sales commission from our deal, we could not have asked for more! Please refer Cornelia to any clients you have here in Tuscon. She is the best!"

  -G.F., Client

"Thank you for all you did to help us find the Tucson home we needed and wanted! You went far beyond our expectations and were so easy to work with! "

"Congratulations and great work! Thanks for your professionalism. Tierra Antigua is lucky to have you as an agent here. Not everyone could have done what you did and seen this through to the finish line."

"This letter is in response to our experience with Cornelia in the purchase of our home. Cornelia did a great job from start to finish. She was very patient with us as we took a very long time to get around to buying a house. She went all over the city and beyond to show us properties, and was informative and professional without being pushy (as we have found many realtors to be). Once we did find the house we bought, she stuck with us to help resolve problems that surfaced after all the papers were signed and many others would have abandoned us. We would happily work with Cornelia again."

  -S.N., Client

"Cornelia was the best real estate agent we have to work with. She is very dedicated and didn't count her time to help us find the best fit for our family. Even after the purchase, you can count on her if you have any questions. I would recommend her to my family, friends, co-workers with any doubts."
