How much to charge tenant for damages to furniture?

[Keno Powers]

Hi. My tenant just vacated a furnished rental property of mine. There was damage like scratches, scrapes and slight water damage to wood furniture which marred the surfaces. Also, stains on couch cushions and the fabric on the dining room chairs that might not come out. I was wondering how other landlords deal with this issue? How do I determine the amount to take out of the security deposit? I'm planning to sell the furniture to make way for selling the townhouse. Because of the damage, I won't be able to sell them for anywhere near what I could have if the damage wasn't there.
