The job seemed to go well, until I realized I forgot, AGAIN, the demon known as the tv dish! 

The tenant is unlikely to help or hurt the appraisal one way or the other, as appraisals are based on square footage, general repair condition of the house (I assume the tenant hasn't destroyed the place), amenities and location, not on whether the tenant badmouths the landlord or has dirty dishes stacked in the sink. 

He does have a daily maid come in and do the dishes, vacuum, etc. for 2 hours a day. 

Most shocking is a humans ability to live in roach infested squalor surrounded in filth clothes dishes and junk everywhere ....and still be satisfied !

The following is the exact language used in my lease addendum regarding tenant care and feeding of the property, also known as Schedule A, a five page addendum made part of the lease signed by the tenant with sections initialed as required to show proof of reading and understanding.The following checked items are furnished by Management as a courtesy to Tenant and are not to be construed in any manner as a part of the rental paid by the Tenant:[X]Stainless Kenmore Refrigerator[X]Stainless Kenmore Stove/oven[X]Whirlpool Dish Washer [X]White Kenmore HD Top Loading Washing Machine[X]White Whirlpool Gas Dryer[X]Wood Extension Ladder 24' [X]Black Garden Hose 25' [X]Wood Workbench x 2 [X]Microwave[X]Ceiling Fan x 2 [X]Window Coverings,10 mini-blinds and one four panel drapery.This/these items are personal property which have been left at the Premises for your convenience.

Still waiting for the world to stop turning and the Russians or North Koreans to take over the universe lol  .

When I got to my unit, I found both kitchen sinks were full of dirty, dish-washing water that overflew the sink and spilled onto the kitchen floor and living room floor.

There's really nothing a tenant can do to damage the roof unless they improperly mount a satellite dish or put up a Clark Grizwold Christmas light display. 

Similar for dish washers. 

He had to show the place stepping over dirty clothes on the floor, dirty dishes in the sink.
