definition of "wear and tear" on carpet

[George P.]

the tenants at one house moved out a few weeks ago. they were there just one year and moved in after the house was freshly painted and re-carpeted.

anyway. there were fingerprints and smudges on the walls all over the house and even areas that you'd have to try to leave a fingerprint. nothing that a new coat of paint can't cover, but the whole house needed to be re-painted.

regarding the carpet, there are dog pee stains and large furniture impressions. they tried to steam all stains out and even used spray chemicals to remove them. it does not smell, but the stains are there.

would you charge them or keep a portion of the s. deposit for something like this? what would you consider "wear and tear"?

how do you evaluate the carpet when tenants are moving out?
