Security deposits
When a tenant moves out, Idaho gives landlords 21 days to return the deposit if the lease doesn't set a deadline. A lease can extend that, but never beyond 30 days. If you keep any part of the deposit, send an itemized statement of what was deducted and why. Good move-in photos and a signed condition report make this far easier.
Late or unpaid rent
Before filing for eviction over unpaid rent, Idaho requires a written three-day notice that demands payment or possession and states the amount due. The notice has specific content requirements, so many landlords use a standard form or a manager who issues them routinely.
Month-to-month tenancies
Idaho's statute on tenancies at will requires at least one month's written notice to end the tenancy. This is commonly applied to month-to-month leases; your lease terms matter too.
