What purchases, not counting real estate, will help me increase my cash flow?
Mutual funds can be relatively low risk and a good starting point. Really it depends on you.  What are your goals? This is a pretty open ended question. These can all be low risk and provide some return.  Note "Less Knowledge" is never a good qualifier for an investment. Your money is your business and you are entitled to know what your business is up to.
