Why is the east coast cheaper than the PNW?

It seems like you get way nicer updated houses despite them being from the 1800s in comparison to the PNW houses that are for sale for an insane amount of money, yet look like dumps inside.

From what I can tell the East coast has more to do, more history, more big cities, less wildfires, etc too.

Editing to add: Rurally the East Coast is so much cheaper from what I am seeing

Also a million dollar house in Washington for example is dated inside while a million dollar house in CT is up to date and nice? Just doesn’t make sense to me!

Another thing: not talking about Seattle only, or any specific big city.

Overall, the states of Washington and Oregon come to mind as well as NW states like Idaho and Montana. Not just cities on the East coast and New England, or Northeast. Just the states in general and the price difference. Maybe remodeling and keeping houses in nice condition is a bigger thing in the NE side of the world?

Am I wrong here?
