Tenant Vacated & only paid for 14 days

[J.N. Miller]

Tenant gave legal  notice to vacate , BUT only paid for two weeks(left on 14th & paid to 14th) paid $700 out of $1400 rent. -- .  I intend to take the remaining two weeks out of her damage/security deposit and refund everything else as the house is fine minus normal wear and tear.

How would other landlords handle this? Im in Washington state.
