Generation X and Millennial isn't really a sharp transition. No generation is, but it is even more diffuse this time since there wasn't necessarily one or multiple "big events" at a fixed date. I don't know if parent's argument is correct, but what is being said is essentially early Millennial, ~1985 and late Millennial, ~1995. Huge difference in many e.g. housing markets. Once people born around the actual millennial gets old enough we might start talking about Generation Z instead.

Most people born in 1985 had their income affected too much by the Great Recession to really take advantage of the lower housing prices then.

Could be the case for many people. I think the commonality between generations might even be declining in favor of other divides. It is in some ways assumed that many people are starting at the bottom and mostly share paths based on development. But I am not sure that is the case anymore, if it ever really were.
