I will be posting rule set 3.0 soon. Still wanting to hear back from one team member, but I will share with everyone my view on this. And I do not get this way too often, but I feel very strongly about dropping the unique item component the more I think about it. It's not a big deal and it would be nice to do a no multiplier challenge. Do what you want with your houses. The whole point of the challenge is you have to move every day -- hard and fast requirement. And each house has to cost more than the lot value of your current house. So, bingo...make your homes worth more by doing whatever you want. Does not matter. When it's time to move...press Build mode to get the lot value...your next home has to be more. Easy peasy, right? I also would like to allow you to add Maxis homes to any empty lots in any world. More options for you. That's the gist of it. The rules will be much simpler.
