Don’t be discouraged…sdrealtor is probably right about their thought process, but you can change that.
We got the same kind of treatment when we first moved in; even had one of the neighbors tell us they were going to move because of all the renters moving in (knowing full-well we were renting). Now, they bring our kids holiday treats and talk to us more than any other neighbors. We’ve been here longer than most “buyers” since 2004 — they’ve largely been foreclosed on or sold already.
One way to get “into” the n’hood is to do work in the front yard. If they see you making improvements to the house (just plant some flowers, pull weeds, sweep the walkway, etc.), they will appreciate your efforts to “keep their property values up.” This also affords you (and them) an opportunity to talk, as neighbors go for walks or do their own yard maintenance or just come by because it’s easy to approach someone who’s working in the yard.
If the wine and yard work don’t do it, they aren’t worthy of your friendship.
