X-CHANGE REALTY & INVESTMENTS

Serving Los Angeles County, CA

Profile Description I specialize in the sale and valuation of established, qualified businesses, representing owners who want accurate pricing, confidentiality, and maximum value. I am an expert business evaluator, providing realistic, defensible valuations based on financial performance, market conditions, industry multiples, and current buyer demand. I actively work with a network of qualified national and international buyers, including strategic buyers, operators, and investor groups seeking well-run U.S. businesses. This expanded reach increases competition and helps drive stronger sale outcomes. Unlike many brokers who simply list businesses, my focus is on completed transactions. I work hands-on with sellers to properly prepare, position, and market their businesses to financially qualified buyers only. My background includes a Business Degree from Munich Business School (Germany), 45 years of real-world business experience, and the creation and sale of six successful California businesses, each built from the ground up and sold for substantial value. I understand valuation, operations, scalability, and what serious buyers expect. I take a selective approach to representation. Businesses must be properly documented and realistically priced to qualify. My philosophy: I don’t just list businesses — I sell them.
