A plumbing issue here, a broken appliance there and soon enough you will find yourself in a hole.

As a PM, I wouldn't leave a negative review unless house rules were maliciously broken or if items in the house were broken or missing. 

Now, this list of rules has been broken but I try to stick to it best I can. 

I don't think newer windows will affect an appraisal too much, unless they are cracked and broken.

Our out of state tenant just informed us her house was broken into today.

Nuisance things: paint, wallpaper (very annoying), holes in drywall, smells (unless it is a sign of mold), cracked windows, missing or damaged screens, no GCFI, flooring, broken handles, damaged cabinets, interior doors on exterior entrances (I see this a lot), bowls under sinks to catch leaks, general run-down-unlovedness.

We had a broken sewage pipe that had to be fixed ($2,000) 3 months after we bought the house and we found mold and termite damage on both of those houses while doing other repairs.

I have a spreadsheet with everything broken out and my COC is 5.72.

I knew it needed lots of interior work, kitchen, bath cabinet, floors, broken windows, plus roof and trees falling in the yard--major huge trees. 

I would suggest turning the water off to the toilets because if the flap needs to be replaced or it does not fall properly when someone stops by to check it can run up an enormous bill real quick.So that the house does not get broken into, maybe add a few light or music  timers and a simpisafe type alarm with monitoring.
