I just drove by 6 of my look alike comps, all within 3 city blocks of the subject. My privileged urban row appraising life has no comment for this thread. Well, maybe i do. Rural appraisers are the storm troopers. From these years of reading i would think you ain't being paid enough. I did some rustic suburban in my youth before the internet and cell phones. I don't know how you could find any driveway without some identifying mark. One time, all the mail boxes were on the corner of the street. I don't do them anymore, mostly big urban.
