Hey Adaesza!

PF is party finder. It's a good way to look for a house, though i have to say waiting like Maero suggested is likely going to be your best bet. Either you can get lucky and get a house in the new ward, or a bunch of people and FC's will be transferring their houses to the new area so a bunch of plots in ARR should be opening up. A good tip is to be up early when the new houses go live and have a good idea of the size of house you want and obviously the money to grab it.

I wish you the best of luck in grabbing a house.
