What to deduct from security deposit when tenant moves out?

[Jeffrey Chang]

Hello.

I am a newbie with rental properties and currently have a few.

I am uncertain what is considered a normal wear and tear when tenant moves out.

My lease states tenant should leave the property in "ready to move in" condition as they moved in.

When my previous tenant moved out there were several holes in the wall ranging from nails to anchor size holes. Walls were dirty and would require painting to get it to "ready to move in" condition.  

What level of dirty wall and holes in the wall do you consider it normal wear and tear?

If you end up getting some or all walls require paint touch up or painting do you deduct this cost from the security deposit?

Thank you.
