Sep is a multifamily real estate investor who has made an unusual transition from multifamily to portfolios of single family homes. When I first heard about the transition, I was a little skeptical. But the rationale for the shift makes sense and is sound. Sep has dealt first hand with the difficulties of managing economically challenged properties in rough neighborhoods. That learning has shaped his current investment choices. Many investors have made the same mistakes in some form. I love his willingness to share his mistakes so that all of us can learn from them.
