Lysis Castro

As a Commercial Real Estate investment advisor to international and out-of-state investors, I seek out investment opportunities in the US with a safe risk-return, that will permit the investor to preserve, diversify and increase their net worth.

Commercial real estate investing is highly localized and its returns dependent on the asset’s immediate economy. It requires financial analysis savvy, expert market intelligence and asset type knowledge to advise your investors. While I maintain a focus on my customer’s risk profile and goals, I educate them on investment alternatives and its potential returns, to aide them in their decision-making and asset purchase.

I am at ease in a team-oriented situation where I can play a key role in facilitating results for my investors. As the founder of Mattis Team, working under the Keller Williams Realty umbrella to leverage my negotiating skills with a team of professionals and cutting-edge tools, I strive to achieve a win-win outcome for my investors. Through Mattis Team, LLC we attend the investor’s asset management needs of procuring and coordinating the various groups of providers required from entity structuring at pre-acquisition, management, and operation during the ownership years, to asset disposition and post-sale.

I hedge my extensive local market intelligenceas a resource to my foreign customer’s advantage, educating and guiding them through the intricate transaction process, from identifying the best deal, to contract, closing and post-closing assistance. My commitment to you is to help you create and preserve wealth, while providing localized market knowledge and research, transaction due diligence expertise, financing arrangement, and exceptional customer service that exceeds your expectations.

Metro-Miami as well as Central and South Florida have grown into a multi-cultural, International hot spot, which offers an array of real estate opportunities for those who want to live, invest, or own real estate and enjoy the “Florida Lifestyle”.

On the advice, we engaged to help us purchase a property for our business. Before hiring Mattisteam, we had been working with another broker without much satisfaction. Things changed once Mattisteam went to work for us. The folks were very responsive and displayed excellent market knowledge.
