Right now, if you are inactive from the server for around 3-4 months, your house gets sold to the goverment. All your hard worked money goes to waste and you are left without a house.
I think this should be increased to atleast 6months, this should give enough time for the player to decide if they actually left, or if something is going on in their life.
Also, if the player knows they will be out of town for a long time, He could pay a percentage of the house price to the government to keep his house.
Ofcourse if a player gets perma banned and has not come back to town for 2 or 3 months his house should be sold.
