On the surface, nothing abnormal. Real estate can be, for someone with knowledge of the market, knowledge of how to rent out property and maintain it (or how to hire a good manager), and the financial end of real estate, can make good money and move up the ladder from single family homes to small apartment complexes, and then to larger complexes...all in a relative short period of time. He was an accountant, so probably more intelligent and informed that the average bear...again, this is not far-fetched, and doesn’t speak to a “secret life” as an arms or drug dealer.
Of course, it also doesn’t speak to the evil residing in his mind, either.
I’ve read that he was an accountant—where did he go to college?
