- Transportation = $2-$4 per mile from las vegas
- Assembly = "Boxabl only sells room modules. We will connect you with a Boxabl certified and state licensed installer in your area."
- The rest = "Whats not included in that price is your land and site setup. This can include utility hookups, foundation, landscaping, permits, and more. Depending on your location and the complexity of your site, this cost can range anywhere from $5,000 to $50,000."
$5k to $50k is a big range. In the video on the article about Musk's unit[1] they state they're initially targeting Accessory Dwelling Units, and specifically California's recently relaxed laws regarding them. I'm not sure the laws specifically regarding those (but there's info here[2]), but I suspect it's a lot cheaper when you're allowed to hook up to the existing house's sewer and power.
It may well be closer to $100k all said and done for a unit not set up as an ADU, but I suspect that the answer to the original question (of who this targets) is "not the people that need to pay $50k in install fees, at least not initially".
EDIT: They also state this in their FAQ (https://www.boxabl.com/faq/):
