This is a general guide to housing as many people have gotten used to the new Safe rules that EA introduced. T2A housing is not entirely safe, house looting can happen so make sure you understand how to keep your house and belongings secure.
House deeds are noobie and may not be stolen from you by a thief or looted from your corpse if you die, as long as they are kept in the top level of your pack. This does not apply to Murderers, noobied items are not protected on Reds.
House keys are not blessed and may be stolen out of your pack or looted from your corpse if you die. I player with a key may enter your house if it is locked. If you lose a key the house owner may use the house sign menu to re-key the house. You will get new keys to the house and the old keys including and copies made will no longer work on the front door. If your house in unlocked, anyone who is not banned may enter. The holder of a house key does not infer ownership of the house. The character who owns the house is displayed to friends of the house on the house sign.
All houses are allowed at least one secure container. A secure container can hold a maximum of 125 items and 400 stones. Secures can only be accessed by friends of the house so things in this container are safe from being looted as long as your house friends don't turn on you. Secures can only be created and released by the owner of the house, not co-owners or friends. To secure a container in a house say "I wish to secure this". To unsecure the container say "I wish to unsecure this". Secures and their contents do not count against the maximum number of lockdowns a house has.
Locked down containers are accessible to anyone who can get close enough to reach into them. Locked down containers can be locked with a key, but they will be pickable by anyone with sufficient skill. Locked down containers count as one lockdown against the maximum number of lockdowns a house is allowed, the contents of the container does not count towards that maximum. Locked down containers hold 125 items with unlimited weight. To lock down a container or any other object in the house say "i wish to lock this down". To release the object say "I wish to release this"
I ban thee - Bans a targeted player and ejects him from the house.
Remove thyself - ejects targeted player from the house.
I wish to lock this down - Lock down an item or container
I wish to release this - Release a locked down item ot container.
I wish to secure this - Secure a container
I wish to unsecure this - Release a secured container
I wish to place a trash barrel - Add a trash barrel or move the existing one.
Houses may be redeeded to be moved from the house sign menu. When you do this all the contents of the house will fall to the ground and be accessible to anyone. When you redeed a house the noobie deed goes directly to your backpack.
You may sell deeds back the the NPC for the full price paid.If you use the detect hidden skill inside a house of which you are at least a friend, the skill will never fail and will reveal everyone hiding in the house regardless of their distance from you. This does not prevent them from re-hiding.
You may attack without penalty anyone inside your house who is not at least a friend, i.e., they will be grey to you.
If someone who is not a friend logs out inside your house, they will be ejected upon login, so there is no fear that someone can logoff inside your house and log back in later when you are not there to protect it.
Most houses larger than the small house have interior lockable doors.
Small Houses have One Secure and 25 Lockdowns and cost 43800 gold from the Architect in the carpenters shop.
I'll give a description of the other house types soon.
