It's funny, because I asked Kinberg this exact question at Xverse, about how many locations they had and how all the mutants would be traveling between them nad he got very curt and was like, "Not all of those are in the movie."
Voila! Look at this! I think I'm one of the first people to bring this up in his/her review of the film. It was perhaps the most jarring thing for me. The locatiosn don't make any sense.
There's a reason Singer kept Magneto and Company out of suburbia -- it just DOESN"T WORK!!!!!! People would notice them.
How about this one?
After levitating a house, having a huge battle inside and outside the neighborhood, Magneto, after mourning and witnessing in horror Jean killing Xavier, takes Xavier and SOMEHOW MANAGES TO GET AWAY!!!!! Nevermind, Logan and Storm, moments later, rush in and have enough time to cry, pick up Xavier's chair, and flee without anyone contacting them to ask what the hell went on at that house.
