Even with that clause, I do not typically charge the tenants unless I can prove they caused the blockage.A clear case would be they flushed a rubber duck or a tooth brush down and that lodged inside the neck of a toilet. 

Some random investor I've never met coming right to me with an offer, I could be taking my clients property off the market and risking losing out and find out I am downwind from the guy going "all in" every hand and hitting his 2/7 flush on the river against my pocket aces. 3) It works until it doesn't.

Oh and don't forget the 3-fingered gloves.Serious answer though: the hand tools missing from your list are: cats paw nail pullers (framing nail and finish nail sizes), flat bars (big and small, I like to sharpen mine up), nail set, speed square, pliers, chisels, level, flush cut saw, and wrenches (crescent wrenches/adjustable wrench and socket set). 

My family is flush with lawyers. 

Disclaimer I was young, dumb, and was flush with recent college graduate money.I would create a separate a pet addendum to your lease. 

We also had the sewage backup problem ---- Empire hired Affordable Plumbing who found out that it's due to tenants flushing down baby wipes.

The sewer guy could not state which side was flushing tampons.

That includes drain cleaning if grease and other stuff is flushed down the drain or cleaning of AC coils for failing to change the filter.

Toilets that use more than 1.6 gallon per flush must be replaced.Second, look at areas of the home, room by room that may be in need of minor repairs: For example, correction of any plumbing leaks or drainage issues, torn window screens, replacement of missing roof shingles, repair of broken or leaking sprinklers, etc.

Otherwise, give him the check out list that you will use and take lots of photos of any problems (don't forget to flush toilets, check the oven and look in cupboards).
