We have exceptionally good neighbors on our block, even though we live in an area many people won't even consider around here. (Old houses on narrow lots with only 8' wide driveways in between, "undesirable" school district, etc.) We bought our house 7 years ago for $85k, and plan to stay here as long as we live in the area, mostly because of how good the neighbors are.
Just a few examples that come to mind:
-We share our stuff. I have never owned a lawnmower. I just use the neighbors. I buy gas for them. We share tools etc. No need for everyone to own a ladder if one person has one.
-We help each other. Cutting down trees, house projects, moving furniture. We help if we can, say no if we don't want to. One neighbor is a nurse. When my wife was home alone and one of our kids split his head open, she came over and helped out until I got home. Her husband also came over, cleaned up the blood, and held our infant while things were being taken care of.
-Lots of young kids that have fun together. I think there were 7 born on just our block the year our twins were born. We babysit each other's kids for free, and even the older neighbors who have grown children enjoy all the young ones. Everyone is ok with having the kids in their yards, so one of us has a nice playground, one has a playhouse, one has small swimming pool, one has swings etc. It is efficient, and less boring for the kids.
-Gardening. Many of us have small raised bed gardens. We exchange produce, seeds, plants, etc.
-We have a block party every summer - 100 percent attendance the last 2 years (12 houses)
-We look out for eachother. Crime is an issue in our area, especially vehicle theft...since we've been here 2 cars have been stolen from our block and many "rifled" through if doors aren't locked. We keep each other updated and call the police for each other. Two teenagers have been caught/arrested because of the vigilance of my neighbors.
For the first time ever, we aren't traveling back to visit family in Wisconsin for Thanksgiving. Instead, we are having a dinner here with two of the other families on our block.
We could easily afford to live in a more "desirable" neighborhood, but have no desire to move because of our good neighbors.
