Water and Honesty

 is a mission in Red Dead Redemption.

Story
A man has found out that there is water underneath the Pleasance house that he wants, to get it he needs the deed, unfortunately the owner of Pleasance house is not handing it over.

Walkthrough
The mission starts in a camp on the road from Macfarlane ranch to Armidillo. A man with a strange stick (remarking he dosen't have the irrigaion tools like the city folk do) explains to John Marston that underneath the Pleasance house there is a stockpile of water that he wants. The only way to get it is if he has the deed to the property. The owner of Pleasance house does not want to leave though. John Marston agrees to get the deed.

Travel to Pleasance House just out some of Armidillo and talk to the owner. He demands $200 for the deed, says he'll by a house in Blackwater (although he doesn't like the people there). John Marston has the choice to either pay $200 for the deed, kill the owner and take the deed or hogtie the owner into giving the deed over.

Either way you have the deed to Pleasance house and can now use it as a normal property (save your game and change your outfit etc.)

Head back to the man at the campsite and hand over the deed he then also pays you some money for getting it. If you killed the owner he notices the blood on the dead and says he didn't want anyone to die and that keep the deal a secret as the owner has a son in Blackwater. Unless the player likes killing entire families.

After giving him the deed and completing the mission, he can be killed and you can loot his corpse to re obtain the deed to the house.
