It seems like there's all prices, depending on the area, and the more work you're willing to do, the better a deal you can cut. I got my place because they needed to sell, it needed work, and I was interested. I'm hoping I'll make enough from the restaurant that I can add some more land to the place and build an actual house. I want the house on the same property so all my Pokemon can just stay there and go between the house and the restaurant when they want. Otherwise, I'm only allowed to bring six while traveling.
