Last year, I found and bought 3 automated bicycle rental stations from a company. I liked it so much that I joined their staff. (I'm keeping the website off so as not to spam. I'm not advertising, I'm looking for suggestions). I'm now working with their partnership department, finding other people who want to buy and run stations.
This is a super-mustachian investment: it's "passive" (very low maintenance), low overhead, and higher ROI than VSTAX. And, bikes!
The problem is I'm not sure where people look to buy. We advertise on Craigslist and are advertising on some business for sale websites.
If you've bought a passive income business or franchise, how did you find out about it? Any tips?
