My congratulations to Sean Cooper. It took me many years of buying and selling houses to achieve what he has at age 30.
I did most of it by buying, rehabbing and selling. Usually three steps forward and two back. Recessions, wrong decisions on neighborhoods and a little piss poor luck, but I finally achieved it. Just about the same time my brother paid off his VA mortgage he took out in 1969.
Real estate has been my downfall on occasion, lol. Glad you achieved your dream.
