As members of the Kidder Mathews Retail group, we leverage net lease specific tools and software that help identify quality real estate, analyze store performance, and ensure that the property is a quality asset for clients.
If a client works with an outside retail broker to help them find their upleg exchange property, you risk potentially losing control and communication with your client; we will make sure you are directly involved throughout the entire exchange process.
We will always work with you to ensure equitable compensation.
The transaction remains within the Kidder Mathews network.
Our team handles everything after the sale of the downleg from identifying properties, reporting, negotiating, and the entire escrow process. You can be involved as much or as little as you would like.
We will methodically vet and qualify potential properties, ensuring that your client finds the right property within the 45-day identification period.
If we are included in the downleg sale process early, we can help structure ways to give your client more time to identify their upleg.
We would like to thank Simon Mattox and team for their professional help in selling our automotive business & related property in north Orange County in early 2022!
We were referred to Simon by a friend of ours after the successful sale of his automotive business the prior year by Simon and company.
After our introductory meeting, we felt very comfortable with Simon and entered into a contract. The team proceeded to put together a comprehensive property and business valuation to make sure we were priced right and competitive. Then, a complete marketing and promotion packagewas created that made it very attractive to any potential buyers. From the start to the finish, his team kept a steady flow of prospects to our front door as they promoted the sale both locally and globally. That eventually resulted in finding a qualified buyer who agreed to pay the close to the initial asking price.
Always keeping us informed of the sales progress, it was the final couple of nerve racking months during escrow where the team really shined. They made sure that all the loose ends were always tied up and that escrow completed on time. Simon and his team have allowed us to move on to the next chapter of our lives and we thank you Simon and his team!
Working with Simon and his team was a pleasure right from the start.
We had a situation where we couldn’t advertise the property for sale as we didn’t want our clients finding out that the business and property were being sold. His team was fully understanding and worked hard to find us a buyer through old fashioned calling on clients. Within hours, we had our first bid and ended up with 3 great offers. I can’t think of another Broker that would go the extra mile like that!
Simon, you were / are a phenomenal super star! Can't imagine anyone better.
Thank you for all your expertise and handholding. Thank you again for your fantastic work on behalf of GFP. What a blessing it has been to have you as our leader / navigator / expert. I can't thank you enough for all you have done for GFP. It has been an absolute pleasure working with you.
We at Devonshire Silver Plaza, LLC would like to express our gratitude to our agent, Simon Mattox and his team.
Our successful closing was due to him, his extraordinary marketing skills, his enormous network, and of course his wonderful advice. His even-tempered disposition and his calm character helped us in every regard. We are grateful to him for selling our property. We highly recommend his professional services.
Simon, was not only a pleasure to work with but very effective at a complicated escrow.
The kind of broker that you want on your team when things get difficult and hard and you need someone to fight for you and make things happen, when it is hard to get it done. First class.
Simon Mattox recently assisted my family with a sale of commercial property we had owned for several generations.
After some discussion about whether we should hire a broker at all, we settled upon Simon, and we could not be happier that we did.
Simon and his team did a fantastic job dealing with our diverse ownership group, soliciting dozens of competitive offers, and ultimately selling the property for a price that exceeded our expectations.
His team could not have been more responsive and professional, and I recommend Simon to anyone selling commercial property.
Our experience in selling our commercial property with broker, Simon Maddox was exceptional.
Simon is a true professional. He responded quickly to calls and messages, knowledgeably navigated and resolved the challenging issues that arose in our complicated sale; and was on top of things and a good negotiator. Looking forward to working with him again on future sales or purchases of properties.
A new client owned an underperforming office building in Carson, CA that had sat vacant for years despite efforts from multiple brokers. He turned to us for guidance — whether to lease it or reposition the asset entirely. After a thorough analysis, we advised that the office building no longer represented its highest and best use. Within just three months, we secured a 20-year ground lease with Chick-fil-A, transforming the property’s trajectory. Originally valued at $5.5 million, the site was sold 18 months later for $9.2 million, delivering a remarkable return and validating the power of strategic repositioning.
Our team assisted a developer client in a 1031 exchange to acquire a 1.4-acre corner lot in Los Angeles County. During escrow, we negotiated and secured two high-profile deals: a build-to-suit agreement with Starbucks and a ground lease with Quick Quack Car Wash. These pre-development commitments significantly enhanced the site’s value and positioned the project for a lucrative exit just a few years later. It’s a textbook example of how early-stage deal structuring can unlock long-term upside.
A client approached us with a challenging inherited property near Slauson Blvd and Crenshaw Blvd in Los Angeles. The site was burdened by two small retail tenants paying below-market rents, coupled with rising property taxes and operating expenses — resulting in negative cash flow. Our analysis revealed the parcel’s highest and best use as an affordable housing development. Despite a long-term lease encumbrance, we successfully negotiated an early termination and brought in a qualified affordable housing developer. We then guided the client through a 1031 exchange into a single-tenant net-leased investment with a credit-rated tenant on a long-term lease, generating a stable $10,000/month net cash flow. From loss to legacy — this was a complete financial turnaround.
