Another common one is tenants not knowing how to change smoke detector batteries & or being confused by the beeping the smoke detector makes when the batteries need to be changed, 

Its a challenge to find a good tenant, especially in the winter.As Victor said... make repairs that prevent additional damage to the property or are essential to safety... leaky roof, broken windows, storm windows, furnace filters, smoke alarm batteries, furnaces & hot water tanks well beyond their useful life, repair holes in foundation or walls to prevent easy critter egress, repair gas leaks, repair dripping faucets, etc.Bob Collett, PM

One day you will love this then the next you will be pulling your hair out.I highly suggest putting in your lease tenant checked all smoke detectors and carbon monoxide detectors.I also make them write that they will keep working batteries in them at all times.This will be like any relationship,no two people are the same.What works with one door might not work with the next.I will HIGHLY SUGGEST READING Managing rental properties by Brandon Turner !!!

A good evaluation module with better representation When I searched on the internet, I got a list of so many quality tracking software.

Also the smoke detector batteries twice a year. 

I think its muratic acid , not sulfuric acid  ( its been a while)  sulfuric acid is battery acid .  

3 smoke detectors went in, the new thermostat (which needs batteries, have to remember to bring some tomorrow!)

I would also look into getting a battery back up for the pump.
