2 Quick points:
1) 1m per week per tile is WAAAAAY too much
2) When introduced, Headquarter Tiles were touted as being Org related. Now they are personal use. I would strongly suggest they need a different name more aligned with their function to avoid confusion such as Residence Tile, or Personal Tile, Estate Tile.
PS:
While on the subject of renaming maybe the patch should be renamed:
"Make Sanctuary Great Again!"
