I bought 2 plots of land a while ago because Vision and someone else said they'd make me a building and I said I'd give them something like 1000 in BTP money but they never made it, and I haven't been here for ages. I'll go and sell them.

Edit:
I can't find them. Maybe they've been sold on now?

1) Adding the date when each plot was bought would be a good idea so you can tell who isn't building anything in the future. That way we can track them in the future. Perhaps PM those who have the lots above and say they will be removed in 30 days if nothing is added to them (or something like that). Keep them there if they reply and say they will build something there, let them sell them if they have no use for them and sell them for them after 30 days if they haven't replied and nothing has been done.

2) Add a mortgage to pay on each house or up the price of the lots. Adding a mortgage would mean people would be constantly paying for the lots so they wouldn't want them. Add the invitation of tenants, then people would be more inclined to build something there so that they can invite people to live there so they can make money out of them.

But it would be well worth it *hint hint*
