Looking to remove knee wall and carpet from staircase and add stained treads, handrail, balusters, etc. 

Example of what a tenant might say - this 2x2' stain on 2 year old carpet was already there when I moved in.  

Currently there is that extremely thin, hard, cheap landlord carpeting (and also an area with cheap thin stick on hard tile squares). 

My lease requires professional carpet cleaning, which would cost more than $500 for a home of that size.Yes, it's reasonable to reduce the cost because she was such a long-term tenant.

For example, avoid wasting time comparing new construction with sun-soaked windows to basement units with stained drop ceilings.

Since this situation was so egregious (IMO), I would either boot them out now, or at least have a serious talk, real serious....If you're going to let them stay I would just get a really deep cleaning done, maybe a couple, and then replace carpet after they're gone.

Agreeable grey with apartment tan carpet (or pet resistant tan carpet).

Stain gone then wash.We use Charisma/Berkshire summer weight comforters from Costco.

Avoid surfaces that can stain or feel cheap like low end LVP.
