Las Vegas land prices have more than doubled since the depths of the Great Recession. Buyers paid a median price of $383,838 per acre last year, up from $166,786 an acre in 2012, according to Colliers International. Land is selling at higher prices as construction gains steam. Developers have packed the valley with apartment complexes, housing tracts, warehouses and other projects in recent years. There have also been more land sales on or near the Strip the past few years.
