Extend auto-demolish

[Jojoya]

A lot of people also buy their housing items/don't craft themselves, so in that respect I believe that furniture could also be counted in the gil sink.

A gil sink removes the gil from the world economy completely. It's not just taking it away from one character so another character gets it.

Going to a vendor and buying housing items is a gil sink. Going to the marketboard isn't (outside of the transaction fee, if any) even if the player later loses/gets rid of the item.

If housing is truly intended as a gil sink, then there should be no refund of the purchase price for any reason (relinquish, relocation or auto-demo). Since 2 of those 3 do offer a refund of sorts, it's not really intended as a gil sink. The purchase price is more of a deterrent ("do you really want to be spending your gil on this instead of something else?").

A real gil sink would be a monthly property tax. Set it at 10% of the maximum plot value and paid to the resident caretaker. The lore explanation would be the fee is to pay the expense involved in maintenance and upkeep of the shared areas in the ward (the money to pay that lala groundskeeper near the Topmast has to come from somewhere). That would actually get players thinking twice about whether or not they really want that house after all if they will be continuing to pay for it.
