Excessive noise can violate a tenants right to enjoyment here is the new York lawExcessive noise and vibrations violate a New York State law known as the “warranty of habitability.”

One of my earlier forum discussions addressed the issue of excess bids in Alabama tax sales.

There's moisture getting in somewhere -- that's what's warping the floors. 

I also have a clause about excessive use charge back  I would use in this case.

Once we removed the baseboards, laid down the moisture barrier, and finished laying down the first few rows of laminate it was smooth sailing.

I pay workmen's comp and have general liability insurance in excess of $1 million.  

Credits to the sale price in connection with rents causes financing issues, the fair market  rent will be determined in the future (rents can be higher) and lenders will only credit amounts  paid in excess of FMR which can lower the equity granted to meet the required LTV, actual agreed credits can be adjusted at settlement but not at loan application.

How high up the wall is the moisture?

When we visit our out of state properties once every year or so, if it's in the fall, we plan on seeding and distributing that moisture control stuff on top where needed, then watering ourselves each day we're there and hope for rain after.  

I would just take plenty of pictures to document the current condition and explain (in writing, perhaps an addendum to the lease) what you will consider beyond normal wear and tear, i.e. marks, gouges, broken door knobs due to excessive force, etc...I know as a tenant it would be hard to have a landlord say you're worried about their little "angels" but hopefully they can emphasize once they realize that you have been burned before.
