Today, Grant Cardone is the founder and CEO of one of the largest private real estate investing firms in the world, Cardone Capital. Cardone’s preference is multifamily real estate, and he offered an explanation of how this works. Since the property was already cash flow positive, that extra $100 each month is all cash flow.
