Scrape the cranberries off the wall that my toddler decided he didn't like. 

I will start with my primary residence , make two unit energy efficient home, I am also planning to install green roof, solar panel, solar water heater, storm water collection , extra thick wall insulation.

Every wall, floor, ceiling, front/back/spine of doors, appliances (inside, outside, and the sticker with make/model information), inside closets, window coverings, window screens, glass, cabinets opened/closed, etc.

We just switched tenants again and hadto do a professional two coat repaint because in some areas discoloration came through the paint we put up when they moved out - after cleaning the walls.

This is really nothing more than a direct subsidy from the middle class to the Wall Street FatCats.

Another is measuring interior room dimensions and loses sq footage to the walls.

That's why it's in the wall and covered by a mirror that tenants aren't supposed to take down.

The floors and lower walls look to be sprayed with a white substance (similar to what I've seen in a mold remediation).

Unless this property is really worthwhile, I suggest you read the writing on the wall and walk away.

If you are not already, cover all the bases by advertising the rental on as many websites or locations (flyer on grocery store wall) as reasonably possible.
