I have a POS tenant now and because of this I do drive-bys to previous addresses.

We try to create some distance by using a PO Box and a Google-voice phone number for our tenants (free service).  

I posted on another LL and would like to get y'alls thoughts on the situation:I'm on a merry-go with a POS tenant.

You should establish a PO box for collecting rent checks and use that address in your lease where rent is to be paid.  

We are newbies too and we went ahead and set up a PO box for mailing payments and to use as our address for everything.

I know you can use a PO Box with the tax assessor's office. 

Looking at things from a long term perspective I personally chose not to buy any property out there that have a POS requirement because ultimately I may have to deal with the intricacies of that if I decide to sell.

Whereas if you find another deal like the triplex, it is completely feasible to pay Answer America $1.00 a call to take messages on your maintenance hotline (they give you a free toll-free number) and get a PO Box or autodebit for your rent payments rather than fooling with a property manager. 

Maybe live there on paper and have my mail routed to a PO box?

Creating a PO Box may help.
