This means the median income to house ratio is roughly 1:5.5
This is fairly standard across the US, and was true even 20 years ago.
For example, in 2000 the median household income ($46k [2]) and house price (~$240k [3]) ratio was roughly 1:5.5. This ratio held true in 2024 as well with a median household income of $83k [2] and a median house price of ~430k [3].
As such, the cost of buying a house as a ratio of household income hasn't changed. The only thing that has changed is the perception.
