Rent
Neck and neck
Las Vegas and Atlanta are about even on rent.
Las Vegas
$2,150/mo
Atlanta
$2,150/mo
What this means for your life
Typical rent in Las Vegas is $2,150 a month versus $2,150 in Atlanta, close enough that housing cost should not decide the move by itself. Factor it into your budget alongside salary differences between the two markets, then pick the city that wins the categories you actually live in: safety, schools, pay, or weather.
