Affordability forces builders to abandon forst time home buyers and seek out an ever shrinking "high end market". In reality it's the same house over priced.
In order for number of units sold/number of buyers in the market to stay Net Nuetral. For ever first time buyer eliminated a new "high end buyer" has to be created.
I assume given the national outrage over inflation this is not the case.
Someone will get stuck holding the real estate bag when interst rates go up and student loans kick back in.
