User blog:Shepherd's ghost/pleasance house

the page for pleasance house says if you kill the old man during water and honesty the place becomes a safehouse for you. however, it says specifically if you "pay him $200, kill him, and loot the body for the $200" i only had $198 so i slit his throat and took the deed. i brought it back to McCallister and the mission was done. i killed the old man, yet i still do not have the safehouse. did i need to have the deed first?
