Rent
Neck and neck
Washington and Las Vegas are about even on rent.
Washington
$2,150/mo
Las Vegas
$2,150/mo
What this means for your life
Typical rent in Washington is $2,150 a month versus $2,150 in Las Vegas, 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.
