FC house are great for the buff they provide, but some kinda overrate them (trying to make solo FC to get it)
Airship/submarine arent as great money making as some ppl want make others to believe
i hear a lot the "workshop give lots of specific items" true but they fail to mention that 95% of those items are to make airship/submarines,
and the good stuff is usually incredibly rare/hard to get, not to mention that some airship piece can be VERY costly !
(not talking about the mats you get from sending airship in explo) because you need then craft these mats into parts and there you need 4 crafter (if my memory doesnt fail me)
another disapointement for those who got a fc house using 3 own character

many MANY people overestimate housing as a whole like the "golden chicken that once you got it, youll become instantly rich !"
(garden for instance ..., crazy how many people believe this part alone is going to make them crazy rich ...)

but i do agree on the parts, as a crafter, to be able to craft in a nice house, in silence with nobody borthering you is real nice, but an appartement can do this all the same

(sorry for my poor english im not native, but hopefully i ve been able to convey what i wanted to say ^^)
