Little did I know they used those very same kids to manipulate me in a way.  

Is there any way to manipulate it so the "analysis over time" section is accurate?

If you're using some sort of callrail or sideline number (I would highly suggest not having your personal cell phone number on the sign) then there's really no way for them to track you down and fine you but you would still want to take the sign down if called.Putting them up Friday evening and taking them down Sunday night is a solid idea and that would be a great way to capture areas that would normally get the sign pulled ASAP - Scottsdale, Tempe, ChandlerThe further west you get into Phoenix you'll see multiple signs on every street corner.

I am an aerospace design engineer working in Tempe, AZ with a B.S. in Aerospace Engineering and an M.S Business Management from Arizona State University (Go Devils!).

Generally, freezing temps and power washing don't mix, I would wait till spring and focus on interior for now.

I guess this isn't the worst thing in the world, but the inspector said the AC would probably need to be replaced in the next couple of years, and from what i read, this temp differential is satisfactory but so close to being unsatisfactory.  

Temp housing would last as long as your rehab takes.

her "wording" is concerning for a section 8 tenantSounds too high maintenance and she sounds skilled at manipulating a lanlord Cut your loses and move on

FNMA listing agents in my area often try to play games and manipulate the MLS status in an attempt to secure both sides of the commission.

As a side note...make sure you have copper still, up here the copper is like gold to crooks interested in risking 10 years in jail for $100 in scrap copper :) - Proper response...no water on...no dealSpeaking of cold temps, make sure you order an HVAC inspection.
