Hi David! Hmmmm...this could be a tricky one. I have lived in a rental that backed up to a graveyard in a good neighborhood with great schools. I spoke with neighbors about their decisions to buy backing up to the graveyard. By and large, most people were not superstitious, and didn't have an issue with the idea of what was beyond the wall. I didn't have an issue either. In fact the bonuses were peaceful quiet, and a plethora of beautiful birds visiting my yard (selling points for you). However...your neighborhood might be a different demographic with superstitious people or people of a faith that might feel weird about buying there.
Advice? Take into consideration the surrounding neighborhood. What condition are the houses in? Can you speak with some of the neighbors about their decisions to live where they are living? Is a church nearby? What do the county records have to say about how often the neighboring homes sell, and for comp pricing? I think once you have answered these questions, you might be better informed about your decision. I'm curious...let me know what you decide, and how it goes. :)
All the best,
Lauren
