We absolutely love working with our clients and we love nothing more than helping them have a wonderful buying or selling experience. Over the years, our clients have graciously written 1000+ reviews about their experiences on sites like Google, Yelp, & Zillow. We've collected them here.

The best Realtor you will ever use. Whether it be for investing, first time home buying, or selling- she knows everything and everyone. She guided us through the buying and selling process, advocated for us and got us the best deals. She sold our house in five days and got us a killer deal on a new place. Sign up with Xuan- you won't regret it.


All I have to say is that Xuan's was amazing and I would recommend Xuan to anyone looking for a home in Austin area.


The first time we met with Xuan, what should have been a short meet-and-greet consultation ended up being a 3 hour long chat on a Friday night---and that's all it took for me to be obsessed!

We came from using Redfin's agents to Xuan, and I have to say that the level of service couldn't have been more different. Right from day one with Xuan, we already had a better and more comprehensive view of what the entire process from start to finish should look like. I am quite a picky customer, and she was top notch with her communication and explanations every step of the way.

Sadly, we were able to find a house with her SO quickly (in the dream neighborhood that I'd written off as unaffordable, no less!) that our relationship did not get to last as long as I would've liked. We spent 3 months and 4 offers with Redfin, but with Xuan we got our first accepted offer in less than a week. But, the house we found was worth the trade off.

Xuan is a skilled negotiator, and we were happy to find that her analysis jived with our own in every case. She joined us on closing day and made sure to ask any questions we hadn't. She even brought us a wonderful basket to celebrate our closing. Since closing, she has remained communicative and responsive to my questions and has provided us with many recommendations on contractors.

Xuan comes with my highest recommendation!


This is my first time buying a house in my life, and I feel so lucky that I've had Xuan help me!!!

I knew nothing about the buying process before I met with Xuan. She was sooooo patient and professional!! During the entire process, Xuan always did everything as quickly as I could imagine and explained my questions very detailed. She knew exactly all the strong/weak points of the houses and could always make great recommendations. My buying process couldn't go so smoothly without Xuan!

I've recommended Xuan to my friends who are looking for houses, and yes I will definitely go to Xuan for all my future purchases!


Rachel was absolutely AMAZING! She was extremely knowledgeable and provided the best advice during the home building process. When searching for our dream home, Rachel set up and attended each tour appointment no matter what location or time. She was available for every text, call, or email and set up reminders for important questions and deadlines. On top of her amazing service, she provided professional videos to keep us updated throughout the entire home building process. We'd recommend Rachel to anyone.


From the minute we met our realtor, Rachel Pulliam to the time we got the keys to our new home, we knew we hit the jackpot! Rachel is super personable which is what instantly drew us to her. We are first time home buyers and wanted to work with her instantly because she was positive, enthusiastic, and motivated to help us find our dream house. And that's just what she did! We were very particular about what we wanted for our first home and yet we were so overwhelmed by all the options. HOA or not? Old home or new? North Austin or South Austin? Rachel helped bring clarity to what it is we wanted -- in large part to being totally flexible, encouraging, responsive, and patient by showing us all the options. When we found "the house", we put in our offer immediately. The first offer on our first house. With Rachel's help, our offer was accepted and closing was seamless. She was hard-working, dependable, and patient with our million questions. We are now moved in and feel more lucky than ever. Thank you Rachel and team for making this experience such a positive one! It made home-buying a breeze -- we are so lucky to be able to say that!


5 stars for Tammy Costello! The Austin real estate market is crazy and Tammy navigates these crazy

Tammy was our real estate agent and she was amazing! God send. Moving to Austin from Cali, we had no

Tammy Costello was a blessing to us. She assisted us in finding a rental when moving from out of state
and was so pleasant and positive during that experience. When it came time to purchase our home,
Tammy was amazing!!! She answered our questions with real honest feedback and the rare instances she
didn’t have the answer, she would tell us that she would get us the answer and then deliver on her word.
Never at any time was there any pressure as there commonly is with agents.
I can’t imagine going through the process with anyone else. Her upbeat attitude and kind character made
her so fun to be around!


Tammy Austin was beyond helpful. She turned what should have been a stressful experience into an
