This man bought a ghost town and lived alone for 3 years. These are the 5 biggest struggles he's faced.

• Brent Underwood moved from Austin to the abandoned mining town of Cerro Gordo, California, in 2020.
• He spent three years living there alone working to bring a relic of the past back to life. 
• Some challenges haven't become any easier, he writes in his new book "Ghost Town Living."

In 2018, Brent Underwood pooled together $1.4 million and bought an abandoned silver mine in the mountains above Death Valley.

Once a thriving 19th-century mining hub, it was a desolate ghost town when he moved there two years later.
