My list is on my other computer, so here goes from memory:Roof, Furnace, water heater, AC, swamp cooler, lawn (I have some artificial lawns), electrical system, plumbing, windows, siding, kitchen, baths, floors, insulation. 

@Todd Whiddon so do you have the developer bug?

Ask for the year of the roof, windows, boiler, and electrical wiring.

Is the park paying water gas and electric??? 

In this case, the prior owner passed and the sole heir wants nothing to do with the place, as it has fallen into disrepair and the electrical would cost about $7k to redo alone if it had to be contracted out. 

In the second bedroom, even after a coat of paint, the tape kept coming off, so I opted for electrical tape instead.

For another, my occupancy of the MIL is so unpredictable and sporadic that it is hard to develop any rationale for the portion I should pay even if I wanted to do so (but it would definitely be less than the sq ft proportion).So, I was thinking of just laying it on the line for prospective tenants, "yes, you will pay all electric/gas/water/cable/trash, and yes that includes for the MIL suite, but I will pay landscaping ($200/mth) and pest control spraying ($30-$50/mth)".It probably wouldn't deter the discovery of a decent tenant, but I'm fearful I'd be planting the seed for some amount of resentment, whereas if I were to communicate (or treat) the situation differently, maybe I could avoid and have a nice Kumbaya relationship.Any ideas on how I could best handle this situation?  

In a rental case I'm guessing most people would not be interested in those circumstances,  and those who would consider the option certainly wouldn't pay a premium for it.So I guess the question is,  when accounting for water, sewer, and electrical hookups,  THEN what time to install and what is the ROI?   

This usually fixes most browser bugs.

They build high quality houses without Electrical which can be a good fit for my skill set.
