Move-out walk through, what do you think of this issue?

[Maria G.]

Hello,

I had my tenants' move-out walk through yesterday. The carpet was brand new two years ago and it's been kept well. The only two issues are some discoloring by the legs of the bed and some discoloring by the shower, where there is carpet.

I am not planning to charge them for it because they have kept good care of the property. However, it does seem like it could have been avoided. They said they had a rug there, but it happened anyway and it is "wear and tear." However, it looked to me that the rug was not big enough, as the discoloring was on the edges of where the rug must have been. What do you think? (The lighting is not the best, so the blackening doesn't show up as clear as when you look at it, but I hope you can see what I mean.)

Going forward, should I tell the next tenant to have a large enough rug? 

Should I consider replacing the carpet in that area by linoleum or something else?

Thanks!
