Even though it didn't affect the integrity of the stairs we agreed, but finding a contractor in the winter was tough. 

My fear is something very unexpected happens and I will make the wrong decision to remedy it, crushing ROI or the integrity of the unit/home.

Your property manager should be trustworthy, honest, ethical and have integrity.

Housekeeping and living habits are an integral part of the ability of mold to grow.

It is more important to maintain integrity than not hurt feelings.Allen Fletcher

If the tenant has been a good client and you feel charitable (there is nothing wrong with a compassionate business as long as you are not being taken advantage of or starving yourself/family), then I'd arrange with the tenant to deliver the keys to you on XX date and you will either a) prorate their deposit back to them according to the days they had "key occupancy" assuming the condition of the residence meets your standards to release the security deposit, or b) charge them the amount of the anticipated date XX on the 1st of August and then return their security deposit upon their subsequent vacancy and cleaning subject to your inspection.Personally, I like the prorating of the security deposit better if you feel like the tenant is a good individual and will treat your property with integrity before they move, and it shows additional compassion by not tying up their money while they position themselves for a new location.In any case, do not put yourself in odds with the law, and do not perform any activity that would allow your tenant to come back against you. 

That reduces your stress, gets the job done, and you can then find a new tenant and start with a clean slate after integrating the lessons you've learned from this one.As an aside, quit acting while you are emotional!

Doesn't that mean the whole integrity of the house is shot now?
