Thoughts on Tiny House in backyard for extra income

[DAn L.]

Using a tiny house as an extra bedroom- no bathroom no kitchen- Good idea or bad idea?  

It's the size of a shed, or average bedroom.  I'm renting these out as an affordable housing solution.  I've designed ones that are on a trailer and ones that can be put up on site in an afternoon.    

I've got an ad up on craigslist to find people who might need an extra bedroom in their backyard.
