Quick check under sinks to see if there are leaks, check the a/c unit to be sure it's not leaking inside (window units), listen to see if the toilet was running, check smoke detector batteries, ask if there were any maintenance issues, and off to the next one.I gave them several days notice, so they could plan for it and to have time to clean.It really doesn't matter how messy it is in-between inspections.  

If the garbage disposer is backing up into the dishwasher, then the dishwasher line isn't routed per installation instructions as it's supposed to have a high point above the drain pipe level of the sink.

Check for water damage under all sinks.

Thank you Ned, that is exactly right, we actually check a condo/townhouse about 2 weeks ago, the thing was a condo with a basement, I cannot tell if it was a condo or townhome, anyway, the ceiling in the first floor was bowing, the 2nd floor, one of the bedroom was sinking, could not tell how this damage was done but the walls came apart from the floor, you could see the roof of the unit bowing inwards towards the structure a bit, and their "general contractor" estimate that for 5k they could straighten the property and level everything, even 1 window and 1 door looked so uneven that you would think  there was something wrong with your eyes...5k for structural damage, good luck with that one, we ran as far as we could from that....but we have seen they do inflate their ARV, since we learned the hard way , we go through these deals with a magnifying glass, I knew I was not so picky, numbers do not lie.Another thing that caught my attention, which I do not know if I am overly suspicious now that I am older, but they want to get the closing for us at the same time/day they are getting the property from whoever they buying it, which it seems to me they try to save on the closing by having a "dual" closing when in reality is just 1 closing and we are the one paying for it...I do not know there are few things that do not click right with this folks.

But if its got at least a half bath (i.e. no tub or shower) which is what I'm guessing you mean, then adding a shower isn't too bad since it either has an ejection pit or something that toilet and sink are draining to.But once you figure those two things out.

You want to make sure that the new tenant receives the unit in excellent condition, and you should want to know that everything is in good working order, i.e. no leaks under the sinks etc....This will cost about $200-$300 and you can either just eat this or build it into the deposit.....worth every penny....

Materials: tub and surround, toilet, sink, vanity, mirror, vanity light, mold resistant drywall, GFI outlet, light/fan combo, flooring, paint.I installed 'luxury vinyl plank' flooring since the bathroom is a high moisture area, which was super easy to install and is holding up well.

My (sink, oven, a/c) is broke will cost YOU hundreds, where for me it is usually handled in 20 seconds over the phone.The PM is so important that when I exchange out of some larger backyard holdings for OOS 1031s, I will locate the best PMs in the country first, then invest in their market. 

They would need some work, there is also one working sink/break room area.

If one person is bidding formica and the other granite, if one is bidding under counter sinks the other set in, one a tankless water heater the other a standard, one laminate the other engineered wood, one a 30 year roof another tile, it makes a big difference on what you get in the final product, and what the appraisal comes in at.
