Maybe its me and my bad luck....it never fails that in a 300 home subdivision, the only people that are out front are my comps? Talking on the phone, yard work, coming or going, etc. Never fails.
As for stealth mode, my Samsung has a zoom out function....works most of the time. You can take a Pic of the house next door, but you will still get the comp in the pic.
I've only been chased down twice in 20 years. I tell them to Google what appraisers do.
Some appraisers have magnetic signs that says real estate appraiser
