I would like to just see LL remove the rolls feature, and just have the letterbox on each property have an inbuilt default AVAILABLE sign. Then as an actual awesome experience, people can meander around regions, until they find their ideal 'home', they like the neighbourhood, they don't see any signs of things that may annoy them like strobe lights from next door etc.
Then they just click the sign which understands that they are premium or plus that they have the linden home allowance to use, and it is theirs. If they already have a linden home, it will say ' by proceeding with this transaction you will lose your other home' and you agree, that then sets the other home to AVAILABLE.
This means that if you do have multiple homes, with multiple accounts, this way if someone wants to swap homes between accounts or just let a friend have theirs, they can make it available when the person is standing there ready to snap it up, in the wee hours of the morning while the moon is covered by clouds (lol had to set the sneaky scene).
This means that LL no longer has to deal with any of this stuff, the only situation they would be needed in is if there was some sort of glitch and it didn't work, lag hitting something like that.
This also as mentioned gives people a more realistic fun experience, like buying that first home, and it ties in with the older promotion images of the couple in front of the home.
