You can now rent select buildings in towns throughout WP!
Look for a small UO sign (like a bank) on the wall of a building. Hover your mouse pointer over it to see the building's monthly rental cost and how many lockdowns / secures it allows. To rent, just double-click the sign and follow the prompts.
Townhouses work the same way as regular houses. You can lock down items, add vendors, and decorate as you wish. Some aspects of these buildings (notably tables and carpets) are permanent and cannot be moved or changed. You'll have to tailor your decoration around these. Anything not permanent will vanish when the rental starts, leaving you a clean slate to work with. Most buildings include a 1-tile area in the front for you to have vendors, deco, etc.
Buildings will remain public and you can't sell them to anyone else. To end a rental, use the "Demolish House" choice from the sign menu. Gold will be automatically withdrawn from your bank monthly to cover the rent. Be sure you have it in loose coin form (not checks)! If you don't have the required gold the house will be rentable again and your belongings will be released and subject to decay and/or pickup by other players.
