You're on Coeurl and so far I'm not seeing much entry activity in the FC wards so far (though it's still early in the week). Even some of the mediums are still lacking entries.

It could be there will still be some small plots left by the time your FC reaches the 30 day mark.

It shouldn't be that difficult for you and your FC mates to earn enough gil for a small in the next month so I'd say try to get a personal this week. If you manage to get one, you can add your friends as tenants to share (you're allowed up to 3 in a personal house) until you're eligible to enter for your FC and get a FC house.
