A standard bar top usually isn't ADA compliant.The simple concept of telling others what you do, or are doing, should be a cornerstone of any business model.

@Michael Marchman ADA has nothing to do with residential rentals, this is a very common misconception.

You're definition of "Nationalization" essentially means that the apartment industry has been nationalized for decades - Fair Housing Act, ADA, etc. 

What ADA impact on the property and building4.

Some things you can do is charge a flat rate and cover the difference or call the utility company and get a 12 month average and make that a part of the rents.3: Personally I don't believe in furnishing or supplying anything for my rentals because my market simply doesn't call for it.4: Depending on your area and what the replacement cost for that building is, inflation can effect your policy differently, for this one I would call your provider and ask.5: Common areas much like an HOA would charge, put a common element/area clause in the lease stating the tenant is responsible for a percentage of costs for upkeep of common areas.6: This may depend on state laws, but I would look into if your area requires ADA compliant signage but if you wanted to put a no smoking sign so long as it's stipulated in the lease then it's your call.7: You can't always do much about guests so long as they don't stay indefinitely or cause a danger to other tenants.

@Shannon K. and @ Steven Payne,thank you kindly for your votes, but the credit goes to @Marcia Maynard (our resident ADA, low income, healthcare, communications guru ). in a previous thread about how to get rid of smoke smell, she mentioned the vinegar bowl method used successfully with her piano performer husband.i just improvised on top of that with a dog house/basement (since bleach would have me faint in that relatively confined space). no smells reported for 3 years

I have seen quite a few SFH in our area placed in such converted homes; you would have to build in the upfit costs into the loan, but if the property is in overall good shape, a few cosmetic and ADA compliance touch-ups, with some interior modifications (mostly plumbing) could work. 

I am starting my search for an MF in the Canyon or Ada County area in Idaho, anyone know of a good deal out there?

Make sure you put as much detail in the ad as possible include room dimensions, pet policy, address of property, and TONS of pictures. 

You'll earn a lot of respect from a lot of people rather than earning their disdain for simply evicting him because of his needs (check with your attorney, also - may be an ADA violation).Some may disagree saying, "It's just business".
