A lot near downtown is also not my cup of tea. 

Have picked this up by hand more times then I care to remember and each time walk away with bags full of nothing but cat feces.

Essentially you both are taking the good, the bad, the ugly legacy issues you potentially have individually and with your generations of families and blending into a new combined unit going forward.Imagine carrying a sack of weighted down junk that tires you down and every once in awhile you look into it to see what is so heavy but then close the bag back up because you do not want to do deal with it right now so keep carrying it.

My handyman used it to repair an area about 2x4' and used about 1/3 of the bag.

I already put charcoal bags out to absorb smoke smell and IMO it's gone.Sorry this is a rambling post, it's been a long day!

It's probably profitable, just not my cup of tea.

Im sure I can tie my shoe, or get my duffle bag ready in that time.TL;DR, dont buy smart keys, they usually are a fast way for a free pass to a smart thief. 

Also bag anything cloth once it is washed to limit re-infestation that will save her some washing.In any case try to have a civil conversation with the property manager, otherwise you will be off on the wrong foot.

And putting them in heavy trash bags .  

I’ll be supplying my own vacuums (thanks Avery) and guest consumables (toilet paper, paper towels, trash bags, shampoo, conditioner, soaps, etc) and the cleaner will provide their own cleaning supplies (cleaning sprays, mops, brushes, etc.).
