Large stains in carpet , how to charge

[Shilpa P.]

Members please help me out on this. Landlord trying to sell the property. High quality Berber carpet with 25 year warranty was purchased ~ 10 years ago. Landlord intends to sell the property.

Steam cleaning was done.

Tenant left large stains on 2 stairs which are very visible.  Several stairs have lot of dirt or discoloration from use, making them look ugly. 1 bedroom has large stains and other bedroom 6' stain but very bright.

Landlord feels this will steer potential buyers to thinking of replacing carpets vs had stains not been there or minor, resale value could have been better. How much can be charged? Entire carpet likely needs replacement by stairs (not to have mismatch as carpet is no longer available). Same with bedrooms. That leaves 2 bedrooms and hallway with mismatched carpets. Replacement of entire carpet seems like the only option at this point. This would have been a cost easily avoidable if stains were less visible or minor. How much can the landlord charge tenants?
