Actually LL mandates neighbors approval to change the ownership of a sim if they are adjacent or corner to corner. The sim I am selling is adjacent to other 2 sim, like in a cluster of fashion sims, and the approval of 2 neighboring owner is required. So 4 ticket are required, buyer, seller, and 2 neighbors, and all of this has to happen in 48 hours because that's how long a 'case' stays open.
For personal reasons I have to close the sim by year end, and if we are not able to finalize the transaction by then LL will lose a sim for a self imposed policy. How smart is that. All the tickets are there but they wouldn't process them because the case is closed. I am not going through the ordeal again, especially after Mae shut the case on my face. If this is their customer servive and you, the seller (LL) are so rich that you can spit on 295$ a month, good for you.
I am not sure if you have to pay the move to another location when you are buying an existing sim, or if they give you this oportunity for free at this time.
