Some issues I've found with Section 8 versus hand-picking well-qualified tenants:  most annoying one, although not major, is they don't have much if any expendable income so they will never buy a can of ant spray or Resolve or mulch the yard or any other maintenance that requires any additional small expense, at least in my experience, so prepare to do it all, filters, light bulbs, etc.  

I'd spray it on (make sure it's not windy and you don't paint the neighbor's house/car!) 

They have stamping and spray coat overlays that greatly improve resale value

Depending on what exactly the issue is, a roofer could add venting (maybe a few hundred dollars) or you might just get a spray foam insulation company insulate the attic (a few thousand).

Typically batt insul is used in this situation but rigid could be used.2b) Spray foam insulation to the wood deck with a new lower drywall ceiling.

Instead of using Spray Foam like we do in most of our intown builds, we used a Radiant Barrier roof decking, which helps to keep the attic cool by making it more difficult for heat to pass through it, kinda like the film on most of the new Low-E windows.Pictures are also FANTASTIC for locating outlets and wires that sheetrockers ALWAYS occasionally seem to cover up!

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?  

Few bath tubs are designed with the jet sprays that will help with proper blood circulation.

. $4 per spray can and needed about 4.

I would spray foam every joist space with closed cell foam.
