For instance, in Ohio (as "flyover" as it gets :-)) the median household income is $45,749, and the median house sales price is $135,500, or about 3x median income.
In California the median household income is $67,458, and the median house sales price is $405,000, or about 6x median income.
So no, it is not actually true that the lower housing prices in flyover states are offset by lower incomes. Housing in California is proportionally twice as expensive as it is in Ohio.
Right. Households often have multiple incomes. That doesn't help the OP's point, though, since people in Ohio are more likely to live in a multi-income household than people in California.
If you look at per capita income instead of household, Ohio gives $135,500/$26,937 ~= 5, and California gives $405,000/$30,441 = 13 By that standard, California is 2.6 times more expensive instead of only 2.
In California the median household income is $67,458, and the median house sales price is $405,000, or about 6x median income.
