Colorado allows real estate agents to share office space with their affiliated title insurers, with certain restrictions, but the arrangement makes some in the industry uneasy. Shared space is permitted as long as consumers don’t have to walk through the real estate portion of the office to reach the title business, the title company’s door is lockable and there is no quid-pro-quo in packaging transactions. Some think the lines are too fuzzy for consumers to know any better. “It has always been my opinion that the shared office or entrance suggests a further inquiry,” said Robert Holman, president of General Title Insurance Company in Ohio and a national expert on affiliated business arrangements.
