3 mos in, tenant got a promo and wants to move, options?

[Alison P.]

I'm a new landlord and just rented out a newly refurbished SFH in June of this year to a great tenant. She just texted me to tell me she got a promotion in another city and needs to move before school starts, this month! She signed a one year lease and has already paid me for August rent. I know that legally, I could hold her to the lease, but I'm not going to do that. There will be a little bit of touch up work needed to cover and repaint nail holes in the walls (she did the place out really nicely but there are a lot of pictures and decor up on the walls) Other than that there is no damage that I saw when I had to go in a couple of weeks ago to repair a leaky toilet valve.

My question is this.  I now have to re-advertise the place and go through applications again and it could take a couple of months to get another tenant in there.  Should I keep her deposit to cover this inconvenience and loss of rent? Or should I just make the transition painless and wish her well?  Really would appreciate your opinions and comments.
