Do you get your money back on these items?

[John Pruner]

I'm thinking of selling the house I'm living in. House will sell in Denver for about $445k.

It has service-able (but worn and slightly stained in places) carpet covering about 700 sq ft. Is it worth it to replace the carpet?  I'm guessing this might cost $1500?

Same question for back yard zero-scaping - wood chips are a little bare....is it worth it to bring in a new load and spread them? I'm guessing this might cost $1000?

Same question for window covers - mixed light drapes around the house - worth doing better window coverings? I'm guessing this might cost $2000?

Thanks for any insight and I hope this was posted on the correct sub-forum.
