Maybe I can help with a rule of thumb. Picture Las Vegas as a circular valley. Downtown is the middle. Make a line from the bottom of the circle to the middle and that is the strip. It basically takes 30 minutes to cross the valley on the freeway so the strip is basically 15 minutes from most houses. A little longer if you live further from a freeway. We have a North/South and an East/West freeway and then there's a circle around 2/3's of the valley.
Please let me know if I can help you with any housing information or searches.
