My first two years of college from ‘69 to ‘71, I had a delivery job with a pharmacy/liquor store operation in Altadena, just north of Pasadena. Lots of large & valuable older homes at the base of the San Gabriel Mountains. Delivering drugs & alcohol (oh boy!), folks would often want to chat a bit. I would wonder how anyone could afford these homes, and came to find that many of them had simply been passed down through a family, with few new purchasers.
Today with so many kids continuing to live with their parents well into adulthood, I think we’re going to see that happening a lot. So rather than more homes becoming available as baby boomers die off, their homes will go straight to the kids, who will continue to live in them because like their parents, they wouldn’t be able to live as comfortably in any other scenario.
