Tell Us Your Story
My family and I have had the pleasure of working with Cynthia Gastelum twice.
We have been on both sides of selling and purchasing a home with Cynthia’s guidance and knowledge. She represents her company with outstanding professionalism from start to finish. Any questions or concerns we ever had she made sure to always answer our calls or emails. We were very fortunate to have a great realtor like Cynthia to go above and beyond as she did. She has made our experiences very comfortable and very exciting! We thank her very much for taking her time with us and giving us nothing but the best! I highly recommend Guarantee Real Estate and Cynthia Gastelum.
Cynthia is very knowledgeable and kept me well informed throughout my whole transaction.
I couldn’t have asked for a better realtor and experience. I would highly recommend Cynthia if you are looking to sell or buy a home/property. She is personable and professional. She hand picks her partners as the process goes along and ensures that each and everyone you come in contact with are at their uppermost level of expertise. She without a doubt will take care of you and ensures that your transaction goes smoothly. Thanks a million Cynthia!
She was super detailed in the process and kept me informed through the whole process.
She was available whenever I had a question or concerns. She made it less stressful even when we had a different kind of experience with this home. She went above and beyond what I expected her to do! Will recommend her to everyone who is looking to purchase or sell a home!
Cynthia Gastelum was AMAZING to work with.
She made our whole first home buying process smooth and easy. She noticed details of what we wanted so we could find out perfect home.
Cynthia did an incredible job for us.
I completely credit Cynthia's hard work and diligence in us receiving $30,000.00 over what we were planning on selling the home for. She made the stressful process of selling a home much more tolerable. She explained the process from beginning to end and I was comfortable in handing over the keys to my home. I've done several real estate transactions and she is by far the best agent I have ever worked with. I would do so again in a heartbeat. Cynthia Gastelum took over dealing with Tesla Corporation because I was telling her I was tired of sitting on hold. She didn't need to take over with their frustratingly long hold times and convoluted customer service but she did so anyway. Cynthia saved me hours of frustration and stress in this aspect alone. Whenever we had a question or concern we could always count on Cynthia being available to answer them. If your selling property you could find no one else more competent and trustworthy than Cynthia Gastelum.
One of best realtor in the central valley

When I first started this journey, I was nervous, overwhelmed, and honestly unsure of how I was going to navigate everything.
Buying a home is such a huge milestone, and I wanted to make sure I was making the right decisions for me and my family. That’s when Cynthia stepped in — and from that moment on, everything changed. She wasn’t just a realtor; she was my guide, my advocate, and at times, my biggest cheerleader. She walked me through every step, making sure I understood each detail, no matter how tedious or complicated it seemed. When challenges came — and there were plenty — Cynthia faced them head-on, armed with her knowledge, professionalism, and fierce dedication to protecting my best interests. There were moments I felt uncertain or discouraged, but Cynthia never let me lose sight of the goal. She kept me informed, confident, and, most importantly, hopeful. Her kindness and patience made me feel like I wasn’t just another client — she truly cared about me, my family, and our future. Today, as I hold the keys to our new home, I know this dream wouldn’t have become a reality without her. I will forever be grateful to Cynthia for turning what could have been a stressful process into an unforgettable journey filled with support, trust, and joy. She didn’t just help me buy a house — she helped me open the door to a brand new chapter of our lives. You are blessed to have an agent like Cindy on your team!!!
I had this ongoing saying that Cynthia is the best in the business, and she truly met and exceeded that standard!
Whenever I needed her, she was there for me throughout the entire home buying process day or night. I will definitely be recommending her Realty services to anyone and everyone who may be interested in purchasing a new home or investing in property.
