AFTER the cleanup!!! 

I guess she would have someone come in and feed them and clean up weekly.

I would just clean up the brick on the fireplace .

Now you have the environmental asbestos issue on top of the water clean up efforts - not a good combination. 

They clean up nice, look great and install easy.

Could you clean up the unit and then raise the rent so you attract better tenants, who may less likely be smokers?

You'll need a Natural Hazard Disclosure Statement too, you want to make sure nothing was on the property that could cause a disaster cleanup (oil dumped, etc.)

I have to clean up some credit issues due to bad RE choices made in the past.

You just need to stay focused and get it done.If the cleanup is a family project then no doubt there will be some that will be thinking picking over cleaning which is fine I suppose as long as they know that within minutes the muscle is coming through and that pile is gone.    

As long as you clean up your present problems and don't create any more.
