Tenant wants to pay for new flooring

[Alice Riley]

I have a sfh that I rent. The tenant just indicated that she wants to stay for her third year and offered to pay to have the flooring replaced in the main bedroom. That's where she spends most of her time in the house and between her and her two dogs, the carpet is looking real rough. Has anyone else been in this situation? Should I reduce her rent for a month to cover part of the new flooring or just let her cover it? She has been a great tenant and I'm very glad she is staying for another year but money is a little tight right now as I had to have some concrete repaired on the outside of the house this month. What do you all think?
