Pay for dryer repair?

[Maddie Rodman]

I gave my renter 30 days notice at the beginning of February because I need to sell my house and since then he has done nothing but try to cause me trouble. I believe his latest attempt to give me grief is complaining of a broken dryer(possible tampered with). The lease mentions the dryer as "personal property" so am I obligated to pay for the repairs? Also the renter has an unpaid bill and I am wondering if I can deny repairs until the bill is paid? (The bill is his portion of a garage repair for damage caused by him.) Lastly, I am wondering how long I have to make the repair if I am indeed responsible-all I can find is documents saying within a reasonable period-how long is that since the property is still inhabitable?
