Brian Brian

Brian is a licensed real estate agent and general contractor. He has been investing in Real Estate since 2010 when he bought his first rental property. Shortly after this he subdivided that property into another lot and built a second rental. He flipped four more properties and held onto two of them. In 2013, he and his family of 6 moved to Columbus and began buying rentals and flipping houses here. In 2015, after doing several deals in partnership with John Horner, he decided to partner up with him and the growth since then has been phenomenal. To date, they have bought and sold 150+ residential properties, almost all of those being rehabbed in some fashion.

In 2015, he and John started building a rental portfolio of single­family and multi-family homes totaling 120+ units. They currently manage an office staff of 5 employees, all of their own rentals as well as rentals for other owners. As a veteran of the US Navy, he takes his duties at work, and all that is required to be professional and diligent in every endeavor very seriously.

Brian’s largest project to date is managing the rehab of a 24 unit apartment complex that was completely destroyed. So far, this has been a 12-month project with a construction budget of $900,000. It is near the end and should be renting units soon. Navigating the city permitting process was a huge learning experience. Recently, he and John started a podcast to educate others interested in real estate investing. He co­hosts the Take Real Estate Podcast and writes blog posts on their website. He is currently working with his staff to create materials and content to enable others to avoid pitfalls as they embark on their path to financial freedom.
