A burned carpet and lease extension

[Manoj N.]

My tenant just informed that he accidentally burned holes on the carpet. Apparently this happened a month ago and he was afraid to tell me. His lease is expiring next month, and we were negotiating for an extension. He wants to live with the damaged carpet for another year and the cost be deducted from deposit at the end of the next term.  I want to get this repaired ASAP (by a professional and paid for by the tenant) if he wants another term. Am I being reasonable in asking for this ?
