When you look under the Collections menu and peruse the non-owned homes, or when you look on the map... why not include the gold and/or crown price for the houses?
I, of course, have had a list since Homestead patch was released (that doesn't have the new houses, which is what made me think of this) but there's innumerable new players all the time that need no go through the super-annoying fast travel/loading screen fiasco for 4 hours just to check house prices. Even things no one sells in one's inventory have prices for vendoring them listed. It's not hard to include. Especially given that it's such a large cost to consider.
