If you want a boulder in your backyard
You’re probably going to have to buy a house that already has one in it. The SF Chronicle has an article about a woman who buys a 1500lb boulder and the delivery person will only drop it off in the driveway, not the backyard. It would cost around $2500 just to get a crane to your house, which you’ll need to move the rock.
