★★★★★
"My interactions with Callum were outstanding. He is responsive, thoughtful, punctual and prepared. As we looked for a home to lease, he was extremely patient with the process, answering our questions, making new recommendations, and eventually locating a place that is ideal for our needs. Highly recommended! Thank you, Callum" - Craig

★★★★★
"Words are not enough to begin to describe how fantastic Callum is. Hands down the best realtor you can ask for. I was moving from Houston to ATX and Callum took all the stress away by asking me all the important details: budget/neighborhoods/size/pet friendly/etc so he could do the hard work and identify the top prospects. Given I was moving from another city, I knew very little about ATX and Callum was beyond patient with answering all of my questions. He never made me feel like I was bothering him and made me feel confident I would find the best place. I told Callum I needed to come look at places and sign a lease in one weekend and he made exactly that happen. He was able to provide invaluable insight about each of the properties and their respective locations. He walked me through my lease and graciously answered any and all clarifying questions I had regarding the details. When I was back in Houston, Callum went to the property to take measurements of all the rooms to aid in my furniture purchases. On my moving day, Callum reached out to check in and ask how everything was going and was able to provide some amazing support while I dealt with the standard “moving pains”. Working with Callum has been the best part of moving to ATX thus far! If you are in need of a realtor, look no further—it will be the best decision you make!" - Hannah

"We were lucky to find Callum by chance and decided we liked his personality and work ethic. He helped guide us through the buying process, he was patient and informative and we enjoyed working with him to find the perfect home for us. He was never pushy and let us take our time to see as many places as we wished, no matter what day or time it was.
Callum negotiated in a very professional manner and kept us updated at every step. He went above and beyond what he needed to do and we wouldn’t hesitate to recommend him, in fact we have done, he is now working with my daughter and husband to help them buy a house. Our only regret was closing remotely and missing the opportunity to witness “closing in a kilt”. " - Mike + Theresa C.

"Callum is truly a fantastic realtor to work with, and I would recommend him to anyone. I wish we could have used him for our out-of-state home purchase! We really enjoyed working with Callum for a second time, and are grateful for his professionalism and care. He truly wants the best for his clients.

★★★★★
"Callum Sinclair helped me and my husband as a first time homebuyers navigate the market in an incredibly chaotic time. He helped us find a home that was a great fit for us. He was always available, answered any and all questions we had, gave us great advice, and made sure to find listings for us that accommodated our wants and needs. On top of that he went above and beyond by putting us in contact with contractors to help us with our renovations after we had closed on our home! Without a doubt we highly recommend working with Callum and Reality Austin if you are looking to purchase a home, especially if you are a first time buyer like we were" - S. George

★★★★★
"My husband, Bruce, and I were very much impressed by how quickly Callum zeroed in on our wants for our home. The properties he chose to send us online were exactly what we had asked for, and in just one afternoon, he lead us to our dream home. It was amazing how quickly he found us a place. And, due to the hot real estate market here in Austin, we were in a competitive bid for the place, which surprised us as it was a rental. But Callum was there for us each step of the way, taking care of things between the landlord and us. He didn’t stop until he knew the house was definitely ours.
Callum’s commitment, professionalism, and genuine warmth make him a great asset to your company. Thank you for sending him our way." - Sharon + Bruce F.

★★★★★
"Cal did a great job helping us to secure a place in an insane market. He was extremely communicative and made himself very available to see houses with very limited notice, as is necessary for a market this hot. Closing went entirely smoothly, and we really enjoyed working with Cal over the home searching and buying process!" - Drew T.

★★★★★
"Callum Sinclair made going through new home construction a breeze. We thought we were in over our heads multiple times, but he always helps put things in perspective and guide us through the multiple stages. He was also a great advocate for us with the builders and sales consultants. We will definitely work with Callum for future endeavors!" - Nick L.

★★★★★
"I worked with Callum Sinclair at Compass when I was looking for a new place. I couldn’t be more pleased with the entire experience from when I started looking until closing day (actually, after closing, he helped me take care of issues I found too). He knows the Austin market very well, he’s proactive in dealing with anything that comes up, and he’s the least pushy realtor I’ve ever worked with. He even found an error in the closing documents that saved me hundreds of dollars! This was my first time buying a house, and it was honestly far less stressful and far less work than I thought it would be. Thanks, Callum!" - Shiv H.

★★★★★
"I had a positive experience working with Callum Sinclair.

★★★★★
"Callum has been amazing and very patient as we ponder with our decisions to purchase a home. His support and guidance are greatly appreciated. I will definitely recommend Callum to my employees when we begin the relocation process soon." - Chris W.

★★★★★
"From the beginning of the process, when I filled out a general request form regarding the sale of my mom's house, Callum was very responsive and helpful. Whenever I had a question (which was quite often!), he was always quick to reply with an email or a phone call no matter what time of day or night. The "For Sale" sign in front of my mom's house was very impressive, as was the marketing on social media and real estate sites like Compass and others. Callum was also very helpful when it came to negotiating. I believe we received a fair offer on my mom's house, which was very important for her current and future well-being. The process was challenging for me as I've never been through it before, and there were lots to do on behalf of my mom. That said, Callum helped us navigate the process with relative ease. We are so happy the process is complete! We wish Callum all the best as he continues to grow and gain even more experience in the real estate world! He's got a great personality and lots of energy to go a long way in this business!" - Jennifer M.

★★★★★
"We enjoyed working with Callum very much. While we were uneducated and completely new to the area, Callum was knowledgeable and extremely helpful in finding us a brand new home in a beautiful area. We would recommend Compass and Callum Sinclare to our friends." - Pammy K.

★★★★★
"Callum was an amazing agent! He went above and beyond to make sure I felt comfortable at every turn. I was a first-time homebuyer and knew nothing about real estate, contracts, down payments, you name it. Callum was always available for questions, met me last minute on tours, and anything I needed he was there. I can confidently say I don't know if I would have gotten my dream first home without him! If you are in need of an agent lookup Callum Sinclair!" - Kimberly S.

★★★★★
"Callum Sinclair is the kind of patient, professional agent who will help you find your dream home as he did for us! Closing with a kilt was a nice touch, and his follow up to see how we are doing is the kind of salesmanship that has been lost to time. We are recommending Callum to multiple family members who are looking to move into the Austin area in the near future. Anybody would be lucky to work with him." - Leila + Kerry L.

He was never pushy (like some realtors can be) and I believe he had my best interests in mind throughout our search. He was incredibly efficient, accommodating, and knew exactly what I was looking for in a home. You won't regret working with Callum- give him a call today!" - Morgan R.

★★★★★
"Callum was very knowledgeable and easy to work with! He helped me find the perfect house that was within my budget. Whenever someone mentions the pains of the home buying process or nightmares using realtors, I explain to them what they are missing out on. If you use Callum, you won't be disappointed!" - Gabe C.
