The pickiness point struck out to me, it makes sense that a cohort with house ownership harder to save for would be more picky when they did manage to buy.
It just clicked that the millennial they interviewed bought a house in an old neighborhood with a lot of gentrification happening, which changes the pickiness question into whether it is a millennial thing or a gentrification thing, which the article doesn't touch.
I'm not sure Dallas does gentrification very well either though -- seems to be about rebuilding or adding on to max the square footage and slapping granite countertops all over. That's another reason millennials are buying fewer houses here. The square footage has skewed bigger. The neighborhood I was born in had a bunch of 1000 or 1400 square foot houses and in the last 10 years most of them have been rebuilt to 2 or 3 thousand.
