My question involves landlord-tenant law in the State of: Idaho
My tenant moved out on 8/31/2015 but still has one key (out of two she had) to the property. She promised to mail it to me the weekend of 9/11, but it is the 17th and I have not received it.
The Idaho law says I have 21 days to refund her security deposit and that is only a few days from now. She is pressing me for the refund and I am pressing her for the key.
Does the 21 day clock start running on her move out day or does it start from the point that I have ALL the keys?
She is an attorney and says it doesn't matter if I have all the keys. She has moved out and that's all that matters. I would be inclined to re-key the property right about now and deduct the cost from her refund if the clock really starts on the move out day.
Any advise on Idaho law here? The code only states 21 days from move out, but it seems while she technically still has access, it would be illogical to consider the property truly surrendered.
Thank you.
