I would reassess how much energy you put into your CL ad (photos, formatting, etc) and decide if it was marketed well or not.  

Sustainability (because we're a nation that imports more than we export and shipping empty containers to China takes fuel) might be another reason, but by the time all the holes are cut in the steel frame and the container has been modified to live in, the embodied energy in that little container (even after taking shipping into account) is probably higher than FSC-certified stick frame construction.  

Why should a house easy to sell have the same fee as a house hard to sell requiring five times the work, energy, cost, etc. and with less likely hood of successfully receiving a commission?  

Looks low maintenance and pretty bullet proof from the outside.

I recommend Nick Rosenberg at Bullet Property Management.

Victoria Wow, thank you so much for the positive energy!

Talking is a waste of your energy.

I told someone just last night that one of the struggles newbies have coming out of a guru course is that they generally only have 1 bullet in their gun...one tool in their kit.  

I help property owners and small businesses improve energy efficiency, environmental health, and impact on the natural environment.

While not bullet proof, if there's no other way, that's probably what I would do.
