Seizing on the popularity of "Flip or Flop," starring Tarek and Christina El Moussa buying, renovating and then selling houses in Southern California, HGTV expands the franchise to include new duos in cities across the U.S. The first offshoot is set in Las Vegas, where Bristol Marunde and his wife, Aubrey, take on one of the country's most expensive, competitive, and unpredictable housing markets. After buying dilapidated properties via auction sales and real estate sites, the couple do most of the construction work themselves to keep their margins high. Aubrey is the designer and real estate agent; Bristol is the general contractor -- and his background as a mixed martial artist comes in handy during demolition. Together, they showcase their skills to complete stunning showpieces worthy of their top dollar zip code.
