Siobhan was amazing. She was incredibly patient; showing us more homes than any of us wanted to see. Siobhan developed a sense of what we were looking for after initial visits were better able to direct us. She was absolutely incredible with following up on information I needed towards closing. When I started the process, I thought it would likely be next year before I either found an existing property or decided to build. It is a surprise that I'm sitting on my new property!

I was looking to purchase my first home earlier this year. I reached out to Realty Austin and was connected with Siobhan McKillop. Siobhan helped educate me on the home buying process and made me feel comfortable every step of the way. She didn't try to pressure me into anything I wasn't ready for. Siobhan let me know that this purchase was something I needed to be sure about since I would be the one signing that mortgage check every month. I ended up purchasing a new construction home, so there was a four-month wait from signing the contract and closing on the property. Siobhan stayed in touch and continued to provide advice along the way. She was so right though, I love my new home and can't wait to write that first check! If you are looking for a Realtor, reach out to Siobhan McKillop, you won't regret it!

Siobhan McKillop did an amazing job helping us find a house that we love. She was very professional and responsive to texts and email. Siobhan met with us twice to look at houses, was very helpful with the process. She gave us lots of advice that definitely sped the process up and got us the house we wanted. I even had two sets of friends that were looking for homes, and she was more than willing to help them out. They found houses pretty quickly too. I highly recommend her.

I met with Siobhan McKillop in late November and by the third week of December, I had found the house for me. The search experience was very enjoyable and comfortable. I also experienced no surprises concerning the closing of the home and by the first week of January, I was a proud owner of my first home. Siobhan’s customer service skills are first rate. She is organized, informative, and timely. I look forward to working with her again on buying an investment home in the future.

Having Siobhan McKillop as my realtor was a great experience! I was worried about the process of buying a house on my own in Austin’s competitive housing market, but Siobhan was with me every step of the way and helped me find the perfect home! From notifying me about available properties that matched my criteria and showing me houses, to being at my closing, and everything in between, Siobhan made my home-buying process a breeze!

If you are searching for your Sweet Dream Home, our entire family would surely recommend Ms. Siobhan McKillop, who made our dream come true in a very short period. Within a few meetings, all at our convenience, irrespective of weekends or harsh weather, she made great attempts to hunt for our house with my very strict specific requirements. Her advice and input were invaluable to us. We feel very lucky to have her as our realtor and in all our future endeavors, we are very sure to have her as our family realtor. I, Nisha Dipal Bhatt, on behalf of my entire family, thank you, dear Siobhan McKillop, God bless.

Thanks again to Siobhan for all her help; she is a blessing and I recommend her to anyone who needs a realtor!!    


Thanks to Siobhan for doing a great job in helping us sell our condo!

We are a few days away from our one-year anniversary in our new house! Thanks to Siobhan for all she did to help make it happen.

We had a wonderful experience working with Siobhan McKillop to purchase a home in which our daughter and son-in-law could live. We flew to Texas from Ohio and had 2-1/2 days to make a purchase while in town and, despite traveling to at least a dozen homes, ended up having fun during what could have been a very stressful time. Siobhan was available whenever we needed her and even quickly came up with a new list of houses to look at after we decided to increase our price range. The house we purchased was vacant for about half a month after closing, and Siobhan checked up on the house a few times and reported her findings until our daughter and son-in-law took possession. She went above and beyond anything we could have expected of her, and we would not hesitate to recommend her as a realtor. She is a true professional and delivered after closing attention that is unusual to find in today’s business world.

It was a real pleasure to work with Siobhan and I will recommend her.  


Yesterday was the two-year anniversary of us finding our house with Siobhan and we drank mimosas out of the glasses she gave us! Hope you are doing well, Siobhan!  


I want to thank Siobhan for all her help and support to make this move possible. I know she extended herself to make this happen so quickly, and I am incredibly grateful. When I worked with her two years ago, I also had a wonderful experience moving in and want to thank her for being extremely professional, very communicative, reliable and all around a delight to work with.   


Siobhan has been wonderful. Thank you for all your help in finding our house, Siobhan!
