Think of the money. Of course, not all niches, no matter how specialized, are profitable. Some don’t have that powerful of an industry attached to them.

A company called StreetShares helps mostly veteran small business owners (also some non-veteran owned) acquire capital for their business cash flow needs by providing loans.

When money is lent to a partnership or S-corporation acting as a pass-through entity (essentially a business that is designed to reduce the effects of double taxation) by that entity’s owner, the interest income on that loan to the portfolio income can qualify as passive income.

Given the opportunity cost of equity, a company can have positive net income but negative residual income.
