Investment sale · Artesia

Jason Keyz is amazing. He knows his business and you can tell that he loves what he does. He sold a piece of commercial property in Artesia for me in just a few short months. Jason also has an awesome team that works alongside of him. I didn't have to worry about a thing because Jason and his team handled everything and made the sell go very smoothly. He got us a great price on our property. We couldn't be happier. I would highly recommend Jason to anyone who is looking for a go-getter. He is honest, reliable, hard-working, very knowledgeable and always available to answer my calls. Jason even dealt with the tenant while the property was on the market and in escrow. I didn't have to do a thing. Jason always kept my attorney and I updated on everything that came up. I could go on and on about him because he is fantastic! He always had time for me when I called, and he was never in a hurry to get me off the phone. Jason is quite knowledgeable in all aspects of real estate. One of the best things I've done in a long time is finding Jason. Thank you, Jason, for such a great experience selling my property.

Office lease · Fullerton

Finding the right temporary leasing office for our needs in Fullerton, CA, was a journey that took us through many twists and turns. Before meeting Jason Keyz, we were with another broker for nearly a year, filled with countless roadblocks and disappointments. However, the scenario changed for the better when we decided to switch gears and bring Jason on board. From the onset, Jason impressed us with his professionalism. Unlike our previous experiences, working with him was seamless and efficient. He didn't just bring listings to our attention; he brought the right listings. It was clear from the start that Jason wasn't just in this to close a deal. He was in it to find us our perfect space, no matter how challenging the search. For two months, Jason worked tirelessly, navigating through the Fullerton real estate market with an enthusiasm and persistence that was both refreshing and motivating. His positive attitude was contagious, making the search far less stressful than it had been. It's not just that Jason found us a space; he found us the perfect space. This outcome speaks volumes about his ability to deliver and his dedication to truly understanding and meeting his client's needs. What stood out most, however, was Jason's persistence. Where others might have given up, he saw opportunities. Where we saw roadblocks, he saw challenges to overcome. His determination was a game-changer for us, transforming a once tedious search into a successful endeavor. In summary, Jason Keyz is more than just a real estate broker; he's a dedicated professional who goes above and beyond for his clients. We're grateful for his efforts and highly recommend his services to anyone needing real estate assistance.

Lease-up + probate sale

Thanks to Jason Keyz and his group, he managed to fill one of my commercial lease vacancies in several days and he obtained a strong multi year lease agreement. He is a man of strong character, with integrity, wisdom, kindness, and wealth of commercial knowledge which is necessary to get the job done. I recently partnered with Jason In a difficult Commercial probate trust sale with a tenant occupied buyer. He continually made himself available, while handling things on the sellers behalf to save them time. This transaction was in a Trust Fund, involving several relatives and could have been very volatile. However, Jason managed all parties with finesses, respect and tremendous ease all the way to the end. I would HIGHLY recommend Jason for ALL your commercial needs, you will not be disappointed! A real joy to work with.

Repeat client

Jason Keyz is one of the few brokers who always goes above and beyond to serve his clients, and he's created a culture at the company where his entire team follows that same approach. He's helped me through numerous deals and I've seen him provide the same exceptional service for dozens of my friends and business associates. It's truly a pleasure to work with him because I know he always has my best interests in mind. In fact, he's actually steered me away from a couple of deals that would have put considerable money in his pocket but would have been bad for me. That kind of integrity is rare these days. I highly recommend Jason and the team at Keyz Commercial. Truly a class act!

Lease · Cerritos

Jason was a pleasue to work with. He helped us lease a property in Cerritos. Jason and his teams communication was outstanding throughout the whole process. Every time I spoke with his team Jason would follow up with a phone call later in the day. We had to go back and forth with the property management over a few things and they stayed on top of it the whole way through. They also made the transition over to the propety management team a breeze. Would definitely recommend Jason for your commercial property needs.

Restaurant lease

I met Jason at a business event. He shared about how he loved helping his clients and has various systems and companies in place to make sure his clients succeed. Being that I have plenty of business type of folk in my life, I'm not easily convinced when one makes such a bold statement. A little background, here. I was in need of a restaurant location, with very specific parameters. I worked with a large commercial brokerage that kept affirming that I would get two properties for two stores. I waited 1.5 years of back and forth with them until they finally broke the news that the offer didn't go through. And then, I attend this event shortly and met Jason. I gave him the details and then within 2.5 weeks I signed the lease. 2.5 weeks after 1.5 years of waiting. How did he do this? While in the waiting room for the birth of his child, he thought about the urgency of my needs and called the Landlord to talk about the lease and make sure to complete the deal. This is beyond professional. I did not ask him to do this. He is that caring for each client that he takes on. Even more so, his team went and did the research and he offered some suggestions for the property that would make it a successful business opportunity. Thank you so much, Jason. This location is ridiculously amazing!
