The housing lists need to be fixed. I went to shirogane and saw like 5 for sale, but they were either loto houses or free companies cant buy them. So my suggestion would be to not add the price but to say this is a loto house plot, or the plot cant be bought if you're in a free company. It would save a lot of time by not having to go all the way to the placard and find out that you cant buy it or that the loto ended.
