You must keep increasing your settlers and their happiness in order to maintain the growth of the Sanctuary. You also need high-level Workshop Merchants so they can sell better stuff to you which will again increase the Settler's Happiness. This Fallout 4 guide will provide you map the location of each Merchant and where they spawn.

Where to Find High-Level Merchants

Now in three variants, the norma Rich Merchants with 10000 caps, the Rich Merchants Less Caps with 2000 caps and the Very Rich Merchants with 30000 caps. The 30000 caps variant works perfectly and does not have the Skyrim bug were you could'nt get the monies when the merchant had more than 32K.

Merchant Spots

The Spot locations that we are about to share are the location where randomly any merchant can spawn. This will be a totally random encounter where you can also find a doctor or legendary merchants. Before hitting these Spots, you must be ready with Minimum 30 settlers(average needed), unlike the Fixed Location merchant which do not demand any Population need.

Spot 1:

Location: Near the Mass Fusion Containment Shed there is a parking lot where you'll see two NPC from which one can be recruited. Then Save the game, leave the zone and come back to recruit the other NPC as well.

Possible Merchant that Spawn

• Ron Staples - Food & Drink Specialist
  • Appropriate Store: Restaurant
  • Population Demand: 20
    
• Doc Anderson - Clinic Specialist
  • Appropriate Store: Surgery Center
  • Population Demand: 20

Fallout 4 Level 4 Merchants

Spot 2:

A tricky and time consuming one, but much need merchant spawn here. That is why we will explain you Step by Step and do exactly the same in order to get this one. To begin with you must Sleep in any settlements for 3 days(72 hours) a bit far from the Med-Tek Research Center.

Note: Save/quicksave after you have slept for 72 hours

Travel to Med-Tek Research center and wait there until you see someone walking down or up the road which is obviously a random spawn. The Spawns include a caravan trader or a patrol and if you are lucky enough then a Legendary merchant will spawn here. The Trick here is that if you don't want this particular merchant or any other person then Quickly load the last save instead of waiting 72 hours.

Possible Merchant that Spawn

• Smiling Larry - Weapons Specialist
  • Appropriate Store: Weapons Emporium
  • Population Demand: 30
    
• The Scribe - Armor Specialist
  • Appropriate Store: Armor Emporium
  • Population Demand: 10

If you are unable to recruit this merchant then the reason will be the population demand where you must have enough settlers. Try to quicksave within the same range of the spot so if that person didn't appear the same exact spot then you can reload your last save and then hit the spot till that person is there.
