I live here in Las Vegas and I love it!
At one point, they claimed 7,000 people move here every month, but also 3,000 people move away every month. Still a major net gain in population, but obviously this city is not for everyone.
Before you sign a lease for an apartment, check into renting a house for the same amount of money. There are quite a few home for rent (people bought, then moved or spouse died or divorced, etc) and you can get some great rent deals on an entire house for the price of an apartment.
I only go to The Strip when I have out-of-town visitors. Not that I don’t like The Strip, but there are plenty of great local casinos with better odds, better buffets and most of them have large multiplex movie theaters. Do not try to get a place to live near The Strip - trust me on this.
Las Vegas was recently ranked as one of the better places to get work - and no, not just in the casino/resort branch. Lots of high tech industries and other businesses moving here - it helps that there are no personal state taxes.
As far as what part of town? Well, maybe a wise idea would be to rent a place at one of the many budget suite type of places for awhile - they have mini-kitchens and are priced right for longer stays. That way you can see what the job market is like and then, once you see where you might be working, you can decide then what part of town to live in. Traffic is nothing like LA, but you still do not want to be working on the far Northwest and living in the far Southeast of the city.
I like living in a 24 hour town, I love the heat in the summer (but it gets colder in the winter than what I was expecting), and there really isn’t a lot that you cannot do in Las Vegas…you have Mt. Charleston 45 minutes away for skiing and mountain air and forests, you have Lake Mead for boating and fishing, you have lots of park areas for hiking and you also have a major airport in the middle of the city that has some great offers to most places in the world for when you want to get away.
Another thing - once you move here, be prepared to see family and friends you haven’t seen in decades. It doesn’t take a lot of arm twisting to get most people to come to Las Vegas, and once they know you are here - well, buy a couple of air mattresses for the living room floor.
