Home is Good
I think having a home is good because it feels like home with doors, windows, walls, roof, furniture and family. A house, on the other hand, seems older while a home seems newer. I believe that a home is cooler because you own it, but you still have to pay taxes or something. I am not sure about anything else, but it feels better when your family is in it. So, calling it your backyard makes more sense because it feels like your own space.
