She was fired about 2 weeks ago, mainly for behavioral issues. 

Stick to the data the comps display, and DONOT overpay.  

Well this was a bigger problem for crews assembling displays who arrive 12 weeks out to begin the build-out and stay 4 weeks after to tear down. 

4) remember what happened in the last crash... wiht listing / sales prices being out of whack, ask what happens if THIS behavior goes away while your holding?

Yes, sometimes you can jail them for this behavior, but it's a essentially lose-lose situation.I definitely wouldn't give them half the bill, but something small so that you aren't completely antagonistic with them.

We have seen tenants without electricity do crazy things, like: use candles for light (resulting in burns to kitchen cabinets, candle wax in carpet, and removal of beeping smoke alarms); run an extension cord from a neighbor's patio to a power strip in which they plugged in more extension cords to lamps, the refrigerator and the gas stove (for the digital display).

set expectations.. display expectations.. enforce expectations..

Think about it, this is when they are on their best behavior and want something from you, namely acceptance.

EXPECT what you ACCEPTyou have accepted this poor behavior, and there is no chance it will change going forward.

Funny because what you claim to be theory is me describing normal market maturation behavior.
