I have never had much trouble with neighbors as I take a "below the radar" approach. Everyone knows when a new guy buys a property as word spreads pretty fast. The pre-conceptions about who you are have already been established. Your first contact will either remove or re-enforce these views.
On my first property 15 years ago, I spent time trying to protect my land by putting up no trespassing signs. This was a waste of time as it only tells everyone a newbie is on the block and is no deterrence to the violators. Tried to talk QDM and that was a waste of time as people always do what is in their self interest, or they resent you for telling them how to hunt.
Over the years my approach has been to spend more time learning about my neighbors and taking an interest in them and their lives. If they need help with a project, I show up to help. I let them bring up deer hunting and listen more than prattling on about my thoughts. My wife and I will stop by their place sometime just to say hi with no agenda. The local farmer who rents my ag land, I work out an acceptable deal, I don't try to get top $$. My approach is slow and steady until I know more about the person. I also look to identify who the neighborhood "Rabbis" are, the quiet guys who know everyone and everything that goes on. I seek to build trust first before a forced friendship with them. If you handle it right, these are the guys that can make or break your reputation.
I think too many people today are self absorbed Face Book types who want to talk about them selves and what they know. This doesn't go over well with rural folks. They are usually a hard working bunch who have seen many out town property owners come and go. I have some very good neighbors that are now friends. We share info about the deer herd, complain about politics, and crack open a cold one occasionally.
I have found that slow, steady, and low key usually is a good approach ...
