I have a large quantity of money on one account and I wish to purchase a house to transfer it over to my newer, main account. However, I don't know if that is possible and rather than spending all of my money on a house that I won't be using, I'm wondering if you can put houses in shared bank so your other characters can use them?
Yes, you can place houses in your shared bank. However, it is limited to one house in the shared bank at a time. Just make sure there are no items in the house when you attempt to place it in the shared bank otherwise it will not work.
