Arthur Morgan will discover Jackson's house during one of the red Dead Redemption 2 missions. This will be a quest for knocking money out of debtors, the task of passing which will give Strauss. You can also learn about this house by chance from one of the characters. If Arthur does not like to follow the laws and regulations, you can safely send him to Rob Jackson's house, first do not forget to cover his face with a bandana.
You will not be able to perform two actions at once, namely, to knock out debts from the owner of the house and Rob him. So we'll have to come back here. This robbery is considered the simplest, in which there is no need to even use a firearm.
By the way, if the mission to collect debts was completed, and Jackson Sr. was shot by Arthur, then when returning to this house for a robbery, the owner may be alive. This is a game bug. But he will not be a hindrance in his plans. Morgan had to find his son, Jackson Jr., and all he had to do was threaten him with a revolver so that he wouldn't fight back and show him the cache of valuables. Arthur will find the loot in the back of the house, in the wall. You can also pick up a shotgun from the living room as a bonus.
