Gaylen,  Thanks for your comments.  I have more to the story....

My husband was standing out in our driveway late Sunday morning.  We live five doors down from another property we own and have listed for sale, where we just put a sign up now that it's allowed and we've worked through the placement with the HOA. 

My husband watched a couple come to the T in the road and look and point at our sign down the street.  They then proceeded to a house on the other side of us, the one they must have scheduled an appointment to see.  When they were done, they looped around to our property, which is vacant, and did stop in and look.  That's a showing that wouldn't have occurred if the sign hadn't been in place.

Rick,

Glad this was a helpful tip for you.  The gentleman I spoke with at the County Tax office was very helpful, and the City of Scottsdale was equally supportive of confirming the correct property line info.

You are welcome, Kathy!  It's still an interesting transition here, as some agents still are not aware that the law has changed.

Yes, indeed, Kathy.
