So I was wondering, I have searched the forums and I think I have the answer. I am not 100% sure though.
When a steward or marshal is in a county for collecting taxes, raising troops, or speeding construction... are all holdings affected or only the ones included in your personal domain?
IE: I have a county with 3 holdings that belong to vassals. If I set my tax collector on that county will those 3 holdings generate extra income, or just the holding capital? This does not seem to work with build increase either. I set my steward on a county and had building going in each holding but non of them seemed to speed up.
Clear answer would be appreciated... thanks.
