Return to Sender for Packages?

[Paul Bleisch]

We've had a half-dozen pieces of mail and a small package or two delivered to our vacant rental property.  I believe the person addressed is the last tenant before we purchased the property - we have no information about them other than the name on the address.  We marked the previous mail and packages "Return to Sender - No Longer At Address" and dumped them off at the post office.

Today, there were five packages - four largish ones in the mail box and one Amazon package on the front steps.  Do we keep doing the "Return to Sender" thing or is there anything else we can do?  Is there a way to file a "no longer at this address" form to halt the mail at the post office?

The irony on the Amazon package is that the house is currently boarded up and getting ready for a rehab. No Trespassing signs, dumpster in front yard, etc...  And there was the Amazon package on the front steps.

Any thoughts would be appreciated.
