It would be pointless since you still need to beat the bids. At the very least, it cuts of the "Pay first -> Relinquish -> Check Aetheryte and hope no one stole he house".

And for people with truckloads of Gil, the real question i how far are you willing to push? The prices of houses are pretty much stable atm, fluttering around numbers that most people know. Problem is, they need to pay the "relinquishing fees" and the land price. Ultimately, I feel like an auction house is still cheaper.

E.g with the auction system, I could buy a mansion for 80mil (maybe 50mil over the starting price). Atm, the same house would prolly cost around 80mil anyway but i also have to pay the land price on the aetheryte.
