Fairline Hill Estates is a myth location in Fallout 4.
Fairline Hill Estates consists of six buildings in a cul-de-sac, very similar in appearance to Tranquility Lane.
If the player has a companion, they will usually mention that they feel uncomfortable and want to leave. If the player takes Preston Garvey to the estate, he mentions that it used to be a Minuteman settlement.
There are several clues that can be found within the estate that possibly reveal what happened to the settlement.
The first clue can be found as soon as the player enters the estate; two Yao Guais will appear and try to attack the player (unless they have the Animal Friend perk). There will also be two half-eaten Brahmin which can be found.
The second clue is the boarded up house containing a group of Feral Ghouls, including a Glowing One.
The conclusion that can be made from these clues is that the settlement was attacked by the Yao Guais, causing many residents to run away. Those left behind boarded themselves into a house which was at one point irradiated, causing everyone inside to turn into Feral Ghouls.
