That is, I don't think moving is usually driven just by prices. Is it? Investing largely is, but investment firms buying up neighborhoods is its own problem.
But a lot of these moves are just improvement moves. Move to a bigger place to have more room for kids. Move to a smaller place to save on mortgage for empty nesters. Move to make your 1 hour work commute 15 minutes. People would love to make these moves, but if the money doesn't line up - it isn't going to happen. Very few of these are REQURIED moves.
For sure required moves exist. Live in a studio and have a kid or two. Get a very good job 1000 miles away. Graduate college. But these are not "most" moves.
Has some actual numbers that are interesting. Moves slowing down as you age lined up fairly similar to my path, I think my entire life moves were at like:
21, 22, 23, 28, 30, 33, 37...
and I may not move again, or if I do I would see it as 10+ years out.
