The areas that have risen quickly over the past 4 years are not the kind of areas that were within reach of millennial twitter-twits to begin with. Activity was more driven by investors, Wall St, and tech money, depending on area.
The areas and cities within reach haven’t risen as quickly. Also, if you think that free Fed money doesn’t have a part in it, think how millennials will afford homes in already poorly affordable markets at higher rates. Something has to give.
