Passive income business ideas

[Lesley Resnick]

I have been trying to brainstorm passive income business ideas.  I am trying to create multiple sources of income.  I do not have the time to run a business day to day.  I am not interested in trying to reinvent the wheel.  Something with a track record and would be scaleable.  It would have to be like Lays potato chips, can't have just one (location).

Ideas:

Laundromat - Cash management is the main issue.  I do not want to collect money from the store everyday.  Finding someone to trust is going to be impossible.

Carwash - I like the real-estate element, but again a cash management issue.  There are a number of local and national companies that are building Wall Mart sized carwashes in Jacksonville. 

Ice vending machine - I have just started to look into this.  It may be a limited market.  The machines are largely credit card.

Vending - On the fence if this is really passive.  Need to source and deliver supplies to the machines every week.
