I wanted to let them know I appreciated things like tightening the screws on a loose hinge or cleaning out a hair clog from the bathtub. 

Not an emergency and it's probably a bad compressor that has burnt up due to dirty coils, likely clogged with dog hair. 

The hair dresser lady needs to be told to either sign the lease by XX day or tell her you will not be renewing.

The sterotype for somebody who didn't have a car payment when they came in was someone with gray hair, they would own their car and pay cash and were sensible about the new car, or somebody who was driving a rat car that they owned for 20 years. 

Someone may have lost weight, gained weight, changed hair color, gotten eyeglasses or contacts, etc.  

As my mentor told me, you should write down goals and be laser focused on them.

Even the cleanest dogs have oils in their skin and hair, and all carpet will eventually smell of animals in houses that have animals, no matter if they have "accidents" or not. 

And/or market it as a great unit for people allergic to pet hair :-)

Yeah, the math works but it seems like splitting hairs to me.

If the HA stayed out of my hair and simply paid some portion of the rent, I'd be fine with it.
