What are some time tested passive income streams?
Last year was a great opportunity for dividend stocks and MLPs. I have a few which are earning 6-9% of my investment basis cost. Municipal bonds are a good value now.  If you have the connections, passive investments in convenience franchises or other commercial property are a good income stream. A Dunkin Donuts used to be an amazing money printing machine.
