I have done 25+ transactions that are from a wide variety of advanced real estate techniques that include rehabbing, wholesaling, dividing and rezoning land, taken property subject to existing financing, purchased short sales with cash, purchased luxury short sales with advanced land trust techniques, purchased probate, and held long and short term rentals.

I'm a retired military veteran and newbie to Real Estate Investing; seeking proven tips/techniques/systems, legit course suggestions, and networking opportunities.

I have an educational background in engineering and business and have grown up in a family that has had several members employed in the construction industry.I joined BiggerPockets looking for tips and techniques that will help grow my property investment empire, so that I may one day take over the world!

Very eager to learn the techniques and different approaches to successfully invest in real estate .
