Some houses were returned to the market recently. These were homes where the user has not played for over 3 years nor had the house even been entered since 2015 or the player was banned. I didn't go through the usual claim for the home since no one had even entered the home in a long period of time.
If you feel I have mistakenly returned a home to market, feel free to let me know, houses can be restored via backups if I've erred.
