Pro rate rent?

[Ron Tafoya]

Hi.  

My tenant gave her 30 day notice today. She is on Month to month.  Rent is due on the first of each month.  Her move out date is August 19th 2016 but she starts her new job AUG 1 and likely will be out by AUG 1.  

This is my first Tenant turnover.  Question is do I pro rate her rent from  AUG 1 through the 19th since the 30 day notice ends on AUG 19th, OR if she leaves on AUG 1  do I just let it go and not and not charge her rent for that month since she wont be there? (Costly for me)  Seems to me she should pay rent up to the ending date of the 30 day notice.  but wanted to ask you guys how this is handled.

Thanks

Ron
