The Power Of Understanding

Jack Britvan SIOR
Licensed Real Estate Broker
Jack Britvan, SIOR has 43 years of experience in Commercial Real Estate. Over 30 years as an SIOR Designated Member and his reputation regarding Ethics, position Jack as an Expert Witness that carries weight in and out of a Court Room. His achievements include both large and small transactions, as well as very complicated to simple renewals. Jack is known throughout the commercial brokerage community as a leader in the industry who is not only knowledgeable and a deal maker, but also extremely ethical. It is not unusual to have fellow brokers approach Jack to arbitrate a commission dispute with fellow brokers. Landlords also call upon Jack to help secure deals. For example, Jack was called upon by a major landlord to assist in valuating some of their properties. After an appraisal was done by both the lender and the landlord's appraisers, the landlord wanted to get more equity and hired Jack to prepare a BOV (Broker's Opinion of Value). Jack was able to find $8,000,000 - $11,000,000 of additional value. Unlike an appraiser, Jack understands the true and potential value of commercial real estate.
