    I had an excellent experience working with Mark. From start to finish, he was knowledgeable, responsive, and truly had my best interests at heart. His understanding of the local market and strong negotiation skills helped me secure my property $10,000 below asking price, which was a huge win.He guided me through every step of the process, answered all my questions promptly, and made what could have been a stressful transaction feel smooth and manageable. I always felt informed and confident in the decisions being made.If you’re looking for a real estate agent who is professional, strategic, and genuinely committed to their clients, I highly recommend Mark!

    Mark Stillings is the best realtor ever! Me & my husband were able to find our first home thanks to mark & his team. We looked at so many houses but none of them felt like home. Mark knew we were new coming into this new home process with zero knowledge & he made sure to cover all the bases from A to Z. He made sure to find homes with the features we wanted & took into consideration of how we could possibly sell our house in the future. Me & my husband work full time so, we didn’t always have availability to look at houses but he went above & beyond to show us a home no matter the time. We appreciate everything that’s he has done for us & we can confidently say that he will be our forever realtor. Even though we’re not family, he will always be apart our ours! ??

    Mark Stillings is the man!! He sold our old house and bought our new dream home!! His assistance during the buying and selling process was second to none with driving around looking at homes, assisting with help for our house to sell and keeping it 100% at all times. I told him from the get go to honest with us no matter good or bad and just that he did! Stayed updating us in every aspect and walked us through some areas of what we did not understand. I would 100% recommend Mark to anyone who is looking to buy or sell a home or property! Thanks again Mark for your assistance and knowledge to make this a very easy process!

    Working with Mark was the smoothest process I've experienced when house hunting. Mark is extremely knowledgeable and well connected to various resources in order to close and move in to your new home smoothly and stress free.

    How do I say how fantastic a realtor Mark is, in such a short space?We started working with Mark in early 2018 and have now used his services to both buy and sell 3 houses in San Antonio. We had some challenging circumstances as well as being overseas buyers. Everything went so smoothly and Mark knew exactly what to do through all 6 transactions. We found him to be trustworthy, knowledgable, professional, very experienced, focused on quality customer service, and was a great host when we visited SA in person. He has an awesome team around him, and is well connected, which makes everything so much easier, when selling in particular. Turns out he is a pretty darn good interior decorator too, as we had to rely on him from afar to refresh our last house we sold. It looked great and we got a good price in such a short time. We are so grateful that we met him and he definitely went above and beyond, exceeding our expectations. You won’t find a better realtor in Texas!

    Mark is a rockstar! Look no further for your next realtor. He is knowledgeable, kind, patient, and goes above and beyond. Mark was referred to me by another realtor friend back home, and I couldn't be happier. My husband and I are a small military family looking to buy as San Antonio was our next assignment. So we flew out, and Mark had an itinerary ready to rock for us, which made it an extremely productive few days. Unfortunately, after our first day in town, we got into a nasty car accident, and Mark drove back to come and pick us up and help us get to our hotel since our rental was totaled. We ended up going with a new construction home, and during that process, he was very present and helped us make building decisions that would allow us to customize our house but still keep resale at the top of mind. Given the events of the last few years, our home ended up suffering MANY delays. However, he stuck it out with us and helped us consider our options along the way. Mark became more than a realtor; he became a great friend. Whether you're looking for a home in a great neighborhood, or a nice place to get a steak, Mark is full of knowledge and helpful recommendations. When the time comes to sell our home, we will be going back to Mark!

    Mark was exceptionally helpful to me in both buying my home in 2016 and selling it in 2022.When he became my agent in 2016, he was ready to take me too look at homes immediately. He has many connections and uses them to get his clients in to look at properties as soon as they come on the market and sometimes even before then. He provided me with excellent counsel when narrowing down what I was looking for and how much I was looking to spend. He made me feel at ease with the entire home buying process.Six years after purchasing my home, I received a job offer that required me to move. I called Mark when I determined that I was going to sell. He provided me with comps for both the rental market and the selling market. While I was moving out, Mark networked with a fellow realtor and had a potential buyer come check out the house before it was even listed. I had an offer before the home even went on the market and closed within a month.Mark has many connections with cleaners, handymen, plumbers, roofers, and myriad other trades people that he can recommend to you for any updates, upgrades, and repairs. Every one that he recommended to me offered a fair price and did excellent work in a very timely fashion.Mark is a Realtor. He works to sell houses, and he is great at it. You should definitely trust him to help you through the process!

    Mark has helped my buy two homes and sell one in Texas and has always been professional, flexible, and very knowledgeable in his industry. He goes the extra mile to make it possible for me to see all the homes I am interested in before making a decision. Mark is easy and enjoyable to work with. I recommend Mark for all your Real Estate needs.
