High Maintenance tenant

[Ethan Martin]

Need some advice. I have a tenant who moved in last week. We did a walk through with a checklist and she kept saying how everything was great. House is new construction, less than a year old, and she wants me to take $500 off rent because she has to clean it. Also, I mopped the floor twice and she just moved in, so I’m betting most of that on the floors are from her… 

I know I can be a pushover sometimes, and I think my kindness to her in the beginning is starting to backfire. How would you respond to this?
