Tenant requested carpet to be changed

[Radu Botnari]

I purchased a duplex that came with one section 8 tenant that has been there for 1.5 yrs. Tenant is month to month and been wanting to move because old landlord didn't want to replace the carpet (worn out and super dirty). Tenant would stay and sign a new 1yr lease if I changed carpet and fixed some maintenance issues. Bottom line is either way I have to change carpet if tenant stays or if tenant goes but carpet is mostly dirty than worn out, so tenant is partially at fault. How should I proceed ?
