Move in/move out Checklist

[Samantha Swenson]

What should I do if a tenant hasn't returned their move in/move out checklist within the time stated on their lease agreement. Our lease says to be returned no later than 5 days at 5 PM and today is day 6... they said they are "working on it.." and can I come pick it up at 8pm tonight!  I do not want to start off this relationship between landlord and tenant being  a pushover and having to chase them down for every little thing, but I Also dont want to be a hard ***  and cause problems. What is your advice on handling this situation
