I'm new to this landlord stuff. I had a tenant that moved out and left no forwarding address what do I do with there old mail. --99.28.xxx.xxx

I mark it that the person is no longer at that address and drop it back in the mail. --98.174.xxx.xxx

Unless you made an agreement with the vacating Tenant that you would hold all mail for them, for a specified time so they could pick it up from you, since it's not your mail, you must make an effort to return it to the Post Office and mark it like razorback said. You are not allowed to open it or destroy it. Also advise new Tenants to either do the same, or give the mail to you so you can return it. I print up a ton of little address stickers (moved no forwarding address) and give the new Tenants some to make it easier for them and encourage them to not open someone else's mail or throw it away. Especially with Stimulus checks arriving, this is a bad time to not put in a 'change of address' when you leave. --72.197.xx.xx

In the future, modify your lease so that tenant gives consent for you to forward their mail to one of the personal references they listed on their application. Be sure to demand COMPLETE addresses for these people. --107.141.xx.xxx

I write on the front: Moved,return to sender, no forwarding address and leave it out for the mailman to pick up and give it to the post office to send it back to sender. Or I write the forwarding address on it if I have the tenant's new address. I put it in a plastic bag, clear, and tape it to the mailbox so the mail carrier can see it. --108.24.xx.xx

Also, remove the old tenant’s name from the mailbox. Some tenants will keep showing up there to get their mail ( because they are using the address still). You can also tape it shut . --68.191.xx.xx

I often write -Please Forward- on them for 30-45 days, the junk mail never stops. But it makes great flower bed stuffing for new plants and fire starter in the colder months. --76.188.xxx.xxx

If it is bill for you, you can do as I do - write the word deceased on the envelop --24.154.xx.x

The rest of us just don’t dare to post here what the obvious and practical solution is for ex tenants who move but don’t have the decency to leave a forwarding address. --98.13.xx.xxx

I would write on the mail "return to sender, no longer at this addess" and drop it at post office, then they would deliver it again! Crazy. So now i take a fat black marker and scratch off any bar codes, and blacken out the Send to Address name and address, so all they have is the senders address visable on the envelope. However whomever sent the mail will get it back and know from the contents or read under the blacken window envelope who its from. But for the postoffice to deliver it again was insane! --208.54.xx.xxx

I guess you can't return the security deposit either? Put a rubber band around the mailbox --172.58.xx.xxx

All mail just mark, moved please forward. Not your problem. --99.23.xxx.x

What old mail? --184.57.xxx.xx

I have two properties that get mail for people I've never hear of. And have gotten that mail for literally years. --69.80.xx.xxx
