Wow not bad =P now you see why I didn't have a pawn shop at first hehehe.
Anyway 50,000 was about what we were thinking for a small one room house that comes with one crafting device of your choice and 50,000 per each crafting device beyond that when you would like to add more.
Expanding the house would be 50,000 per room.
A small keep or small tower would run 100,000 with 50,000/tile of expansion
A large castle/tower would be 1,000,000 (this would most likely be used as a guild hall, but there will be no rule precluding a single player from gaining one).
In the future RP tokens will be added to prices but since we don't have many DMs at present it would not be fair to ask this of the players since they have very little chance to earn them.
