You're either going to sell at a loss and have to make the difference up at closing from your other assets or you're going to work out the debt on the property, get tenants in there and dispose of the bad memories whenever you can do so at a reasonable profit in the future.

You have two steps available to you here, and you might be able to do both of them, you can at least do number 1.1) Given you already have the cost segregated on your building, assuming you had a good quality cost seg study that breaks out the different pieces of the roof, dispose of the old roof and take a loss on that old roof. 

How to properly operate the disposer.

Sorry about that I worded that incorrectly I meant unexpected repairs things that I should set aside money for just in case something does happenSo for the expenses you mentioned such as garbage and landscaping, those would be considered operating expenses not unexpected expenses since I know I will always have to pay for garbage disposal and landscaping

Its all disposable.

My point is I have never met YIMBY that both could be affected and had no limits (ie would be good if a garbage disposal sight moved next door). 

Take photos and get them to sign off that anything left behind can be disposed of.It is 'funny' how people have money for their kids' sports and eating out, but not paying the rent.

I don’t have the certification to take out and disposal of asbestos.

Pet policies and pet-walking and waste-disposal areas.

Any surface that is porous (not hard like countertops, etc) will need to be disposed of and you will need to clean the heck out of even the hard surfaces.
