hardwood floor repairs

[Carey Branam]

We finally got our toughest tenants yet, out of our house.  Unfortunately they chewed up all of the hardwood floors.  Looks like their couch or chairs did it in the living room and every single bedroom is chewed up from their beds.  I hate that people are so inconsiderate.  My question is, how do I charge for this?  The only way to really fix it is to redo the hardwood floors but refinishing all of the floors would be in excess of their deposit.  Just curious what others have done in this situation.  We are preparing the house to sell.  The hardwood floors would have been a nice selling feature but now it's an eye sore unless we refinish them all.
