Ouch, you just missed the first lottery round for the big addition of 5 new wards. It would have been the best possible chance to relocate. However, you may still have a decent chance. It looks like there will be over 150 Ishgard houses available to personal buyers on Behemoth. If you are going for a FC house, you can probably still get one without competition in the FC only wards.

Wards 1-6 and 25 are FC only
Wards 7-20 and 26-29 are Free for all. When bidding in these wards you will be presented with a choice of bidding for yourself or behalf of a FC. Make sure to pick the appropriate choice!
Wards 21-24 and 30 are private buyer only

The next bidding round starts in a few hours. Don't rush your bid. The bidding period lasts for 5 days. If you want to maximize your chances, wait a few days and see how the bids are stacking up on the houses. That way you can at least dodge some landmines that get a ton of bids early on.

When you bid, it will ask for a deposit of the full purchase price. Make absolutely sure that you are at the proper plot and that you are bidding on behalf of the appropriate entity (personal or FC). Once your bid is placed, there are no takebacks. You cannot cancel it, and a GM cannot cancel it for you if you messed up. So take your time. There is no prize for speedrunning your bid. At the end of the 5th day of bidding it is results time. Go back to the placard and either finalize your new purchase if you won or collect a full refund if you lost. If you forgot what plot you bid on, you can see your lottery entry under Duty -> Timers -> Estate
