There is a chance the expansion will add more wards to the existing residential areas but I don't think it has been confirmed. When you start going through the end game stuff after completing the 2.0 story will provide opportunities to increase your funds well. You can keep an eye on the residential status by going to the main aetheryte in the main cities and choose the residential option. You can choose the spot you want to teleport to and it will show the status of each lot in the ward. Wish you the best with your guild.
