1. You have a yard for you and your kids to play in. I know a number of people who love this. You can send the kids out to the yard without having to be there with them. When the weather is nice you can do this most days. And, the kids can have a blast doing it.
2. You can grow a garden. Flower garden or vegetable garden... I know a number of people who do this. This brings them pleasure in multiple forms.
3. It's a place that's yours rather than someone else's. When you rent there is someone else that owns it and you live there. Some people like to own and have more control over their space. It's about agency.
