Here in WI, the landlord is required to provide a mailing address of an actual location on the rental agreement (not a po box) where documents/notifications can be sent or dropped off in person (however it is ok to also require rent be sent to a PO box).

I'll look for it, if memory serves correctly it wasn't a Po box, but I think I do remember it being in TX

I also have a PO Box for them to send checks too.  

If they are not text savvy, have them mail rent to a PO Box in your town if you're not comfortable with them dropping it off in your mailbox.

You can get a PO box for responses and make up a name (Acme surveys) so you don't have to provide your name or address.

I see it is a PO box.

Get a PO Box as address.

Perhaps start using a PO Box location and set up a google phone # that goes right to your email but at already it doesn’t call your phone.

Also as stated a PO box is not appropriate for a company address.

I use a PO Box simply as a way to separate my business and personal life, plus any Return To Senders will be more obvious in a PO Box (for me, anyway).
