Tenant wants out after 3 days

[Tom Herzog]

On Friday, I signed a 12 month lease with my tenant. She paid the security deposit and first month's rent. By Monday she called, saying that she didn't want the house anymore and she wants a full refund. Her cited reason is due to the condition of the house. While filling out the move-in condition sheet, she noticed some minor issues- signs of water under the kitchen sink and by the laundry tub, roof sealing not complete, garage light burnt out, and signs of a mouse (I have not seen anything that would lead me to believe a mouse has lived there). I told her that I could have everything taken care of within a week, but she still wants out. 

I don't want to keep a tenant who doesn't want to be there, but I feel I'm owed something for the trouble of relisting and finding a new tenant. Per the terms of our lease, I can take one month's rent plus a fee for cancellation. Is it reasonable or should I consider giving her a full refund?
