Look at the layout of the bushes, opposed to other houses.then compare how quickly, effectively, and sensible the ability to farm would be. For instance the nexus retro house it's bush layout is pretty much the same as the basic house. You'd need to travel to each corner. If I remember from memory there is about 3-4 each corner. Opposed to the basic house with the water in the center with lots of grass, or the castle. Or others. It's a horrible choice for farming.

But is this a great house just to decorate, have fun it. Or settle out some house fights? Absolutely yes it is. But farming? You have much better options you don't need to pay 20k for. Infact nothing at all but a small 50 gralat fee to change your house at most.
