Exactly. I live in a 2nd tier city. My friends who are home owners have very middle class blue collar jobs. Examples include auto mechanic, security system installer, and local delivery truck driver. None of them got "help."
How old are they? I know plenty of people who bought a house 30 or 40 years ago on blue collar salaries. I don't know any <30 year olds who bought property without parental help.
I just picked a metro: Baton Rouge. Median home price there is around $160k, although naturally there is plenty of inventory available for less than $100k. Some of it's in pretty dismal shape, but, looking at Zillow, there are non-zero houses in this category that look livable. The median HHI in Baton Rouge is $45k. So it would take about four years for the median family to save up enough to buy something that's at least livable, assuming they can save ten percent of their income.
I couldn't say whether blue collar people make at, above, or below the median, but it strikes me as likely that at least some of them will be able to purchase a home in this type of metro.
