What to send the tenant
Send the remaining deposit, or a written, itemized list of each deduction with its cost (free letter template), to the tenant's forwarding address before the deadline. Keep proof of the date you sent it. Normal wear and tear generally can't be deducted, and a deduction is strongest when your signed move-in report shows the item was in good condition.
DepositDay walks you through the move-in and move-out inspection with timestamped photos, counts down your Washington deadline from move-out day, and writes the itemized deduction letter.
