Just So Everyone Knows: Housing

[Mimilu]

Step 1: Find an FC that wants to sell their house.
Step 2: Strike a deal
Step 3: Join the FC
Step 4: Place the gil into the FC chest (no limitation.)
Step 5: FC leader makes you the new leader of the FC.

Plot, house, and deed has now been bought/sold/traded. Nevertheless, the original point being made contains good information for people buying non-FC housing.

And what happens if the FC Leader doesn't do step 5 and just kicks you out of the FC?
Sure, you could try ruining their reputation on that server but all they have to do is transfer and wa-la, fresh start with your gil.
You could try reporting them to the GMs but most of the time, they won't get involved with player-on-player, in-game transactions. And you would be ratting yourself out for buying a plot through none-official ways, which Niqote has just pointed out is a punishable offense.

Just fyi
You can trade the house permit after you demolish the plot
So ya you can trade it.
And they can be bought on the Mb....

Permits are for constructing houses, you still have to buy the plot and the previous owner still has to demo their old house first.
