New tenant is moving in, what can I deduct from the Sec. Deposit?

[Nate O.]

I am a couple weeks away from placing a new tenant in my first rental property. The tenant that is leaving has kept the place reasonably clean throughout their stay. I'm going to have the carpets cleaned for the new tenant - do landlords normally deduct the cost of cleaning the carpets from the security deposit? (This property is in Nebraska)
