Early Retirement (quest)

Early Retirement is a side quest

Walkthrough
Following the strange signal leads the Sole Survivor to a terminal at the Campus law offices, which speaks of an Institute Courser, who planned to interrupt a meeting between two escaped synths, R3-11 and PR-15, at Fairline Hill Estates.

At Fairline Hill, one discovers the body of the Courser. Searching his body will give his mission log, which tells more of his activities, the locations of the two Synths and the location of a terminal at University Point where he recorded reports on his mission to later upload to the Institute. Reading the log will spawn the two characters.

R3-11 now goes by the name "Burner" and is part of the raider gang at Back Street Apparel, while PR-15 is a Gunner Captain named Carol Janssen at Hub City Auto Wreckers. Killing them or deleting their records at University Credit Union will advance the quest. Note: Even if the records are deleted, the characters will still be present at their respective locations and hostile to the player character.

After killing them or deleting the records, accessing the University Credit Union terminal will reveal the location of the key to the Institute safehouse, in a mailbox near Hub 360. Entering the penthouse at Hub 360 completes the quest.

Bugs
If you do not listen to the strange signal as soon as the quest pops up, it can bug out so that the quest will never progress. To fix it, open the console and type. This will force you past having to listen to the signal and the coordinates will pop up.
 * Alternatively, if you're unable to use console commands (Survival Difficulty, Xbox One or PS4) you can head to Campus law offices to progress the quest, albeit without the quest marker to guide you there.
