Check the gutters, downspouts and grade of soil/cement around the house and make sure it's draining properly as a lot of basement moisture issues can be fixed by backfilling and extending your drainage further from the building.

Certain lots/land *require* certain types of homes (for example, two store full walk-outs vs. a rambler/ranch), soil, easements etc. and that's just the land!

Make sure all of the soil is graded away from the house.

Try to get them to see it from your side; you are a reasonable person and would like people to have the quiet enjoyment of their home and thus have tried hard to avoid having many restrictive "house rules", but your intention in renting to them was for them to use this single family residence in a typical way.An imperfect analogy:When Hertz or Avis rents you a car, sure you have "use of it for X days" - but they are not expecting you to enter a race with it at Watkins Glen, or use it to transport 150 bags of potting soil, stacked into every space in the trunk, back seat, passenger's seat, and roof.

@Caleb Coats ,@Sandy Sciales and @John Underwood the main issues we ran into with our systems came from restocking, and logistic details.

Dear all,I have tenants that moved out leaving behind heavily soiled carpet and I have deducted damage from deposit.

Water, sun, great soil, not a ton of people compared to other parts...And just in the last week I read an article which seems to dovetail with these assumptions, except the author has a research staff to help him with the evidence. http://www.scribd.com/doc/53865070/GMO-April It is an enlightening and well researched report on what is likely to come.
