I have gone through his key ring and put the 3 keys he needs to enter the building and his apartment on a separate keyring.  

They brought the whole 3-ring binder and started going over it with me from pg 1. 

A ring camera pointed at the driveway is an excellent way to keep an eye on things.

Quick same day turnaround and provides most inspection services.I have also had clients use Champion inspection services.

Finally, use drapery rings so they glide on the rod easier.  

I would get a google voice number to give out to tenants because I can control when they rings and when I receive messages etc.

Yes, we have ring cameras at multiple properties.

(On Maple Street only about 3 blocks long I owned 12 houses...once I bought into the street I found value and became known as a cash buyer who maintained their properties so my phone rang and I shook hands on the street to keep it ringing.)Always check ARIES the Lucas County Auditor site.

If unsure how, lookup local chapters of MFH landlord associations, they are champions of this and may find data from them.

I'd prefer not to give an entry code to lots of different delivery drivers if possible.In this position I'd wait until packages actually started getting stolen before doing anything, or maybe I'd get a Ring doorbell or camera.
