Every room was extremely cluttered with trash and were filthy.

IMO, it's unwise to show a unit with the existing tenant still resident - - you're showing the mess and clutter which always makes the unit look too small.So, showing for a prospective new tenant I wait until it's ready for move-in (yep, that's a vacancy, but it pays me back with better tenants).Showing for the purpose of selling is another matter and the tenant will have to allow access when given written notice of intent to enter the residence - - knock on the door and then use YOUR key.

I take lots of breaks, I allow myself days where I just go to the park with my dog to read a fiction novel, I don't sweat a cluttered house.If I could give advice to my younger self, I'd tell me to do the above - forget the dishes and go play with my daughter. 

I fire pit all the small branches as I cut it to eliminate “clutter”. 

Potential tenants have a hard time seeing past the mess/clutter/dirt (or whatever it is) and envisioning it as a nice/clean place for them and their family. 

IE it likely wouldn't make sense to do a trash out and clean up the yard if the most likely buyer is an investor who is going to gut the place anyway (and can see past the clutter).

*Mods, if you feel that this is clutter feel free to lock it or whatever.So below I will start.

You may find that once you empty it out, you'll realize that it was just all the junk and clutter that made you feel like it was a loser.

But instead the baby is getting tossed out with the bath water.Let's not clutter this thread any further with these unrelated discussions.

I suppose it could also just be some random disgruntled citizen that knows they're against city code and they don't like them cluttering up the side of the road.
