Why is this not the solution?

[MilkieTea]

So if someone is willing to pay a flipper over 50M for it, lets say 100M, why wouldn't they just bid on a house for up to 100M instead? They might get it for less. And you have zero chance of the placard taking your gil and running off.

Flipping only exists in the first place because SE tried to pretend that supply and demand don't affect prices on a limited resource. This would introduce that factor back in. Flipping isn't going to die, but its going to severely drop off.

Because 100mil off a flipper is static - that's the price and it won't change, AND flipping is a nearly solid enterprise within the game, with ways to ensure you get your house as there are dedicated discords for this, with active communities (I'm sure someone who is active in such communities will come in here to pipe up). Whereas having the "potential" to get the house for "less than... or greater than" 100mil is not a solid opportunity, with plenty of chances for failure.

This idea is, honestly, worse than the lottery system we're about to get.
