Teleport to House, also known as 'House Teleport', teleports the caster inside their player-owned house, right next to the exit portal (or within the house), regardless of the 'location' of the house (Rimmington, Taverley, Brimhaven, etc.).
When adventuring, a player could bring runes or tablets for this spell to guard against dying from poison and fully heal themselves instead. Dying in a player-owned house will cause the player to respawn outside the house portal, NOT lose any items, and have all stats restored to default levels.
